aa - week 12 - spatialisation

right to left - two copies panned left+right. each had sweeping eq (freq of high shelf) and sweeping volume. also slight delays - when sound was too the left, the RH sound was delayed a few ms. then as sound moved to the right, each file was adjusted to give more distant sound a delay.

back - two copies. HPF on one, LPF on other. HPF lower in level panned to 9.30 oclock, slight delay. LPF relatively higher volume panned to 11 oclock, slight reverb.

then combined the two concepts to get a sound that moves from left forward to center(ish) and then back to the right. using three copies, with the third having a BPF and phase inverted (just for good times) - using all above techniques.
the picture is of this one - you can see also a bit of reverb mix automation, as the sound gets closer the mix gets less reverb.

the fourth is slightly to the right. I used 3 copies, each with a stereo eq setting and some phae inversion, and also slight delay. i like this with no reverb.

CC - Week 11 - integrated setup (3)

I haven't changed the bidule since last week (other than changing various values and a little bit of routing).
Above is obviously a screen shot of Plogue. I didn't take one of Live :( at the time I forgot and didn't save it, keep'n it live and all that.
In Live, I introduced a number of samples into the Simpler and then adjusted individual settings. Also I used a reverb with an edited envelope send.

So thoughts this week ;

I did this using a VSTi style piano for access reasons.. but noticed the main thing is timing. Using midi FX in plogue, and then programming edited piano sounds rhythmic style (in simpler) makes for a bit of an abstract output - so either work on making it more regularly rhythmic or more regularly abstract.

Using semi tuned samples means playing in key - that's just a practice with the final setup style issue.

and I can't quite work out how to change tempo :? humorously enough I just happened to have all the delays in the factors of 250ms and 333ms so it wasn't too bad.

The audio is a 2 minute excerpt from a longer duration.

AA - week 11 - spectral synthesis

Once again I had some fun with Plogue.

I quite enjoyed mixing up the freq + amp signals (fft) between different sound bases.

The sounds I was using was a noise source, 3 tone generators (1f, 2f, 3f), and samples from my FM and additive synth adventures.

To these I added a little parameter modulation, lots' of messing with the routing and volume adjustments.

I also played with the FFT window size, but found I liked it low (512).

CC - week 10 - integrated setup

I went into studio 5 to once more battle with the Disklavier.

This, the second time, was once again a battle with technology.
And once again, when all hope was lost, rebooting the device saved the day - it only took me an hour to get it working :P Hmmmmph, rebooting a piano


I did spend at least 5 minutes just playing the Disklavier from the Novation just to watch.. and initially when I used both the In and Out on the Novation, I had a 1/2 sec feedback loop happening.. much enjoyment !!
the waves of key movement travelling up and down...

RESULTS
The latency is large enough to effect performance, so I will have to incorporate such into the performance - unless there is another setting yet to explore.

The responses are not always as expected, example being it not always playing the notes the transposition bidule should be playing.. I think this was dependant on note velocity and duration.
This I assume is down to the Disklavier's mechanical action.

And the Midi buffer bidule occasionally decided to not send anything. At this point, I am not sure whether it was actually the bidule or perhaps the Disklavier not reacting.. further research !!

Still,
much great advancement on the glorious road to revolution and freedom !!!

The example below is not the best section of the recording I did. However, I did it on my mp3 player without checking, and it is the most free of distortion..

aa - week 10 - additive synthesis

Once again I got a bit too excited with Plogue.

I did the basics; introduced multiple oscillators and gave each one a volume, pitch, filter envelope.
Had an extra fun time by putting summing the individual volumes, and using that as a divider on the end signal to keep it from going to far over 1 (except for those nasty filter squelches)

Then gave the envelopes a negative potential as well..
This caused me to spend a while on neatening up the filter envelope - as the filter cutoff has particular tendencies to bug out when too high or low.. this was one of my extra fun times :) giving it a changing gradient as it got closer to 20.

I also had a bit of fun with polyphonising the whole thing..
I was using mulitple UI's to keep it a reasonable size, and the master UI would call up the individual oscillator UI at request.. however when the whole thing was polyphonised, I would get a UI for each polyphony voice. ie lots..

So this image below is the inside of one oscillator.
I had four of these, and each was polyphonised, and then inside another group.



But by polyphonising in this way had other problems. When I would unpolyphonise so as to edit, the master UI button would disappear - so I would have to replace it.

Here is the 'voice' UI.



Picture of the sound.

CC - WEEK 9 - INTEGRATED SETUP

I've got to say, that Plogue has been incredibly stable for me at home. So when I went into studio 5 with Freddie, and forgot to save - it crashed. I think it's probably crashed, like, once over the last couple of months...mmmm.
So when it crashed I was, like, totally surprised :P

Anyway, we came out with a bit of experience, and thanks to Freddy, the idea of using an FM oscillator for a modulator - very cool..

So I acheived my finished product at home.

I had trouble getting the relative Parameter Modulator to act in what I considered a coherent manner. Setting it up with an osc producing a Ramp waveform, the modulated parameter just continued to go up + up... even using other waveforms it behaved surprisingly.
Using a triangular wave produced an effect like the wave below. The sine was similiar, and the square like a triangle...

aa - week 09 - FM synthesis

I got all excited and decided to build a multi-operator FM synth.



Finally I worked it out and got a reasonably manageable (I thought) 4 operator version working.



Using the audio matrix for routing was incredibly useful (especially once I started hitting the random button!!)
Not that all the channels did anything :) 1 - 4 operator in/ out (source and modulation). 8 in LFO. 7 + 8 audio out to mixer.



My major problem was that I forgot about frequency scaling (for melodic style output).
Once that was sorted my major minor problem :) was the oscillator bidule output level - as an audio module versus a modulator module.

The modulator intput I multiplied by the note frequency, which I figured would give me a range of 0hz to the pitch for the modulation freq, which would be adequate with the amplitude range of 0-1.
But this wasn't enough!!! I found to get really effective I needed to crank the output (using up to 10).
I'll have to give this more thought.

mtf - instrument of wobblyness

well i've built the instrument of wobblyness, and well, it's a bit messy...




BUT BEST OF ALL - it's mounted in a cardboard box :)
lo-fi aesthetic for all round budgetness...

At various stages throughout its construction, it went through design changes :)

Last of these was to introduce a seperate power supply for everything that wasn't the tape motor controllers (attempt at noise suppression - that pulse wave just leaks through everything)...and I don't have enough jacks.... so alligator clip mania !!!

Anway, it just begged for a patch bay style interface (more alligator clips), which I'll probably just keep on expanding because there is still a lot of space.

Presently, I am using two walkmans, two square wave oscillators and two ring modulators.

There is space on the Arduino for another 4 motor controllers, 2 square waves, 2 ring modulators and then there's I think 2 more switches on the 2003 chip which could be utilised.

I doubt I'll get as excited as I could, as 2 simultaneous sources with modulation is probably a good level of interactiveness for real time performance - although that pulse wave out of the arduino (driving the motors) through some ring mod sounds great !!

Here's a sample featuring two tapes of speech, and 1 ring mod.








thanks to Seb, for his invaluable assistance, help, aid, facilitation etc....

mtf - week 08 - physical computing and aesthetics

We (John Delaney and myself) did the appropriate building and connecting during last weeks actual forum ie controlled note on/off for 3 oscillators from cubase.

I don't have any evidence whatsoever, but hopefully John will post something soon[1] and I'll use one of his pictures :)

This physical computing exercise was quite cool - combining this with some sort of envelope controls and it'd almost be a real synth - bass line mania !!
I did notice that the circuit made a lot of noise, unfortunately I just remembered and have yet to ask anyone why - or even for that matter do a bit of experimentation.

As to the instrument aesthetics, I've got to say I think most of Reed Ghazala's instruments are a bit unsightly (I may be exagerating a bit when I say most:).
I think it is good that he got nicely carried away, but I'm a bit of the put it in a simple structure and there you go.
I'm willing to admit that if I'd done this for the length of time he has I wouldn't be surprised if my instruments were just as garish.

I'd quite like to mount mine in a cardboard box, but I think the idea of a clear plastic bottle should work and whilst not being as perhaps exciting as it could be, will suit my idea of aesthetics quite nicely thank you very much.

cc - week 8 - live 2

In the dim distant days of the mid 90's, I used M[1]. This had a time warping feature as a simple graph (known as time distort), nowhere near as powerful as the Live feature...



Above are two different warp versions of a sample. Combined with a pitch shifting envelope I made this particular sample sound quite different, in terms of timing and duration and melodically.
Here is a little sample of the two loops, each repeated twice.


With the drum loops, the warping combined with the warp mode and pitchshifting (global and envelope), make for nice glitchy drum sounds.
This I combined with the follow actions creating a few 4 bar repeated phrases, which make it much easier to manage the liveness.

I appreciate much the sample manipulating features in Live.

The restrictive aspects is quite interesting. The limited effects are not such an issue because of the afore mentioned manipulating features, giving an amazing amount of variety out of a simple sound. And the limited matrix of potential clips, is not necessarily an issue when aiming for 45 seconds of sound, but with a bit of keen editing one could easily introduce a single clip of mulitple drum loops warped and manipulated extensively.

aa - week 8 - amplitude modulation

well little luck with making anything useful la AM sounds ie "sounds that mimic natural or
human-made sounds".[1]

had a lot of fun with modulating the modulators though.
Spent a bit of time on a scaling constant distance style AM, had to find the cent to freq ratio, but never felt i really understood whether it was doing what i wanted it to.

Then when mucking about with self modulation, I decided that a divider on it would be great ie pitch shift.
So a short delve into the spectral bidules reminded me of what FFT actually does ie average out frequencies.
This left me wondering what other options there were - I didn't want to use a seperate oscillator because I wanted feedback !!
Alas I decided that it was so much easier using a seperate oscillator and putting a divider onto the freq output of the note extractor, and it was - now my next excitement will be how to effectively change the wave type's of multiple oscillators simultaneously.

Anyway, my bidule featured AM and RM, with a fixed frequency and a moving frequency, and a sort of self modulation - which with the divider worked very well as a scaled movable modulator as well.

mtf - week 7 - physcal computing 2

blah, can't get the maxruntime to recognise or initialise or whateverise the serial port on home computer :(

worked last week,

serves me right for trying at home- will keep workn at it..

anyway, again I'm thinking this is non-stop potentail. At first I was a bit dismissive of basically building a novel sound generation device and then conrolling it with a computer. I was a bit thinking this was overkill and just not necessary.
Why wouldn't you build something and then just play it, OR just play with a computer and not mix the two.

However I have inadvertently come to the pont where I see my former thoughts a tad small and whatever that word is where you are a bit limited.

I'm not really sure how all these exercises we've done tie together, or how they can be tied together - eg trigger a sound and change the pitch so will have to read the exercises again and consider.

I'm not convinced I'm interested in using this tool with my proposed instrument - to a major extent I'm more excited about playing it real time and not lugging more gear around than I have to, but will give it due thought...

aa - week 7 - basic synthesis

First going into studio 4, I made some Enoesque ambience :)

Second time, I took the Roland SH-5 to studio 2 and made Doctor Who noises, I spent a while but that's all I could make.



One thing I noticed was the non equal tempered keyboard. Does it ever play semitones ? It did make stuff sound more Doctor Who though.

It was very hard to make "natural" sounds, perhaps if I'd thought about it more it might have been easier.
But it just seemed that every time I made a new sound it just sounded like Doctor Who.

mtf - instrument design

I've had minimal luck with toys. They've been too limited, and a couple are now too busted.
As such I propose to bend a cassette walkman.
Creating a new device - The Wobbly Man... or something like that :)

By changing the voltage to the motor I can change the playback speed/pitch, and even reverse direction of the tape.

This will be controlled/played by either a) a pot, controlling the variable voltage ouput of a regulator
and/or b) the thick pencil line on a piece of paper controlling variable resistance.

I will have multiple tapes each with unique sonic characteristics giving an array of potential playback timbres.

The instrument will consist of the walkman itself, a voltage regulator as created (or attempted) in week 5, and a pencil and a piece of paper.
I have yet to discover exactly how to integrate the pencil and piece of paper.

As for packaging, I plan to mount it inside a clear plastic drink bottle - giving the needed rigidity for such things as patch leads and also a lovely view of exposed wires.

cc - week 07 - live live

Well again, I have an amount of familiarity with the software to be used, so I jumped in.

I did an amount of pre-preperation, in that I played around for a while, then had some effects and loops pre-arranged before recording.

Example being the following envelope of the rez on the filter effect on track 4 (amusingly enough, Live occasionally seems to mix up the parameter names in some effects - probably the VST's themselves - in this case, the rez, is the cutoff).

I'm not sure how my version of 'Live Lite 6 M-Audio Enhanced Edition' differs from the university version, but I could use one VST effect and two Live audio effects.

I also played with the starting times and loop points of the samples.

Also setting the quantise to various values and restarting samples so they were not necessarily in time - I think I first started doing this to emulate badly beatmixed records :)
This is quite obvious at the beginning.



Once I had recorded an arrangement, I couldn't help myself doing a tiny amount of neatening :) Changing some volumes so they weren't too outrageous, also a bit of deleting to get it below 5 minutes.

And for good measure, I inadvertently decided to keep a semi-disco version.

In this version I mapped scenes to the keyboard, and played them this way.
I found this conflicted with other real time mouse editing, in that it changed the focus to the clip attached to the mapped key.

I did quite an amount of re-editing on the arrangement to neaten, shorten and make funkier (probably about 1 1/2 hours worth) - 90% of the ideas in this came from the 'live' version. I just did this because it was 9 minutes, and once I got started I couldn't stop editing :)

This example I bounced down two tracks so I could extend the 'bass' line at the end, so there are 5 clips effectively playing (on four tracks still), this also freed up an effect slot which I used to master compress - still working within limitations :)

f - week 6 - arduino

Had a bit of fun getting the arduino to work on my home windows machine.
After a few software problems, got it running OK !!

It's great, I didn't do anything withit , but conceptually it's great..
I don't know about the programming side of it, but ... it's great.

The possibilities of the arduino are vast. I really can't say anything but it's great. I've always been excited about the idea of an interface to the real world from computer land. And using this to do all sorts of random things, like controlling motors to controlling sound...

Anyway, about the assignment.

For exercise 3, Horus, I used two pots. One was a 1M and the other 1000k and they both worked fine. I was a bit curious about the way the controllers attached to unconnected analog inputs used the input from the preceeding analog input, but after a bit of reattaching the pots to various of the analog inputs I decided that it just happened to work that way :)

cc -week 6 - more humanising

more of the black sabbath.
this time with eq and more effects.

I also went through and manipulated the note timing a bit more, added a slight amount of pitch variation on the snare, and pitch bending on the bass.

The main thing I'm impressed with is the changing of the timing on all instruments, and the minor pitch variations on the bass.
From when I played bass in a dub band, the slight variations in pitch through sliding to a note, pulling off of a note. And the slight timing difference between the left and right hands all provided slight inspiration for this weeks manipulations.

audio arts - week 5 - Interaction Design and Sound

I opened a jar of jam today, and noticed again the pop up safety seal feature
- when the jam is initially put into the jar, I assume it is done as a still hot product, so when the lid is sealed it creates a low pressure area inside the jar. This effectively holds a little 'button' in the middle of the lid, down. When the jar is opened, the pressure equalises and the little button pops up with an audible click - very satisying, and you know the the jam should still be good to eat :) Free from tampering and airborne bacteria.

This is good design, it is not in anyway intrusive, or does not effect the jam experience.
Very functional, I think as far as form is concerned, perhaps the size of the pop-up section which would affect the volume/pitch of the pop. The pop feature is not necessary at all, it exagerates the opening experience, without the pop it would be a little hiss as an inrush of air takes place - from my research the pop feature is more on food products that would have required cooking, and so would have a vacuum seal, and are at risk of spoiling.




also I considered the new public toilets, a sealed environment for your grafitti-ing pleasure.
These toilets feature a voice over accompaniment that describe where you are in the security process ("door locked" etc), and various features available. Whilst the features are also described by buttons in braille, having them illustrated audibly will at least prepare any blind person for the adventure of feeling their way around for the appropriate buttons.
There is also musical accompaniment ("what the world needs now" - a classic bowel movement inducing tune), no doubt to make sure you stay reasonably relaxed, yet aware of where you are. I have never stayed in one long enough, but at some point assumably there would be a warning voice to say that the doors are about to automatically open.

The audio feedback is a generally spoken affirmation of your action. It is direct feedback that also explains which button you may have just pressed.
To a person with good vision, this voice over/music can be annoying and annoying. The voice itself featuers a slight slap back echo to potentially give it a more natural feeling.
But to a visually challenged (blind) person perhaps this continual audio commentary is useful.

The interactivity starts with the door open button, accompanied with a flashing led to display its current occupancy state, then everything apart from dropping your trousers is done by button pushing - not real buttons however, but those that you just touch and possibly work through measuring inductance ? The buttons are not satisfactory as far as buttons go, so some response is good for a personal satisfaction thing - but as these buttons have fairly obvious response (toilet flush, door open) the reponses are a tad overwhelming.


Obviously the first example would take a fraction of the technology required for the second - the automated toilets have been waiting a while for technology to be cheap enought to build these :)

mtf - week 5 - circuit bending

I didn't seem to have much luck with this, other than being kind of impressed with my soldering :) I managed to do some fairly fine work !

Apart from that mmm.

The two toys I've been working with have proved not particularly helpful.
Following on from my post last week about the lion king thing, Seb suggested that the voltage regulator would prove useful :( It didn't work, so sad, I've tried it 3 different times so far - probably one of the components.

That said I also talked to Seb about using a pot to control voltage, he drew me a picture, but still again no luck :( Here's a photo with a bit of annotation showing how I did it.

Then I attacked the xbox - here the main problem was repetition. I found a number of cool effects, but they wouldn't repeat with any consistency. I think they all sort of depended on shorting out between something and one speaker connection or lcd connection, which makes me think that the short result may depend on the voltage output of the speaker or lcd at the time.

One sound involved a short noise, that I could manipulate into a crackle by shorting out appropriate buttons. This left me with not enough hands so I decided to try and make an automatic button pusher..For this I used a slot car with the spinning axle as the alternating contact - I figured that it constantly spinning would regularly break any connection.
It worked, but was far too noisy.. apart from the fact that the noise I was trying to manipulate so was so bloody hard to make anyway (lack of repetition).
