Anybody remember Cosecha? And the fun we had pulling together PS011, recently released by the outstanding PublicSpaces netlabel?

Well, Mr Fonseca and Mr James  require your help again. Our newly formed collaboration, Half-BIT will be providing an art sound installation at Netaudio’s EXPANDING 09 Festival on 14 November in Barcelona.

Half-BIT is all about collaboration. It’s our raison d’être. It’s how the whole project was kicked off. And we want it to be global. Our first track started life as a wonderful IDM piece from Alka’s “Dog Lost in the Woods” album. It was remixed by Fernando Fonseca, then remixed again by Kieron James. None of us have actually met. Alka is based in New Jersey, Fernando kicks around Barcelona and Kieron inhabits the far less urban-cool, though equally chic Cheshire, UK.

What we need from you

Just like Cosecha, Fernando has asked Kieron to seek parameters to create a new source file for him to glitch the hell out of for a sound installation on 14 November (when Kieron will be tucked up in front of Faithless at Manchester’s Warehouse Project). And we need YOU to help with those parameters.

This time, Kieron intends to use two of his favourite VSTs: Ohm Force’s Symptohm and BigSeq2 from Audio Damage. He’ll request some parameter values to create the sound (e.g. send  a number between 1 and 5000) and you’ll tweet back with your number. Just like Cosecha, Kieron’s not going to disclose which values are being requested, but unlike Cosecha, Kieron anticipate far fewer requests being made of the contributors. (Promise!)

Once Kieron has  handed our sound over to Fernando, he’s going to work even more collaborative magic to create a very special piece for Barcelona by using a max/msp patch that will gather live data from Twitter that mentions Barcelona and the Expanding’09 Festival that will mash the glitch out of the original sound in real time.

Play your part by adding a comment below with your Twitter username, or tweet us up with #halfbitbarcelona in your tweet.

We’ll keep you informed of progress via our favourite collaborative social networking wonder-drug: Twitter.

Sound 1 – Ohm Force Symptohm Output [30/10/2009]

Thank you to all the contributors for providing numbers today. Below you’ll find a SoundCloud player which previews the three bar loop your numbers have generated. Don’t get too excited just yet. There’s a second stage to the process where we mash this up using Audio Damage’s BigSeq2.

The table below illustrates how the sound was generated from the numbers supplied:

Parameter	Request	Received	Contributor
Note	1-12	5	@alka
Note	1-12	5	@BlueEydGlambert
Note	1-12	12	@dust_bunnies
Note	1-12	3	@fbish
Repeat (0) Reverse (1)	0-1	1	@groovecriminals
Tempo	110-180	123	@heuristicmusic
Beats	2, 4, 8 or 16	8	@HipGnosis13
Loop Length	1-4	3	@leeconnolly
Symptohm Sample	1-123	72	@LucidAcid
Slide Time	1-4000	1	@madebyrobot
Morphing	1-6	3	@PublicSpacesLab
VCA	-30 – +4	-7	@pure_tone
VCF Cutoff	60-8000	4358	@retorta
Voice Filter Type	1-3	2	@ronsens

 

None of the contributors was aware of the parameter for which they were submitting a value. The request simply read (for example), “Please send me a number between 1 and 4000 (inclusive). Thanks.”

Phase 1

Here’s how the loop was generated:

The first four contributors provided the notes for the loop. I preselected C major scale and with 12 notes in an octave we have a pattern of E, E, C, D.

Parameter 5 governs whether the pattern should then repeat or reverse (0 for repeat, 1 for reverse). So the second four notes are D, C, E, E.

Parameter 6 establishes the tempo of the loop: 123bpm. Parameter 7 sets the note length: 2 being a minim, 4 a crotchet, 8 a quaver and 16 a semiquaver. The loop length was established as 3 bars by Lee Connolly. The sample preset from Symptohm is 72 (literally counting through the sample files in the Symptohm library!) and the remaining four parameters establish the filters applied.

Loop 1 – Symptohm

More to come! Stage 2 will be the mash up and sequencing in Audio Damage’s BigSeq2.

Phase 2

Phase 2 of our Netaudio project applied a VST plugin named BigSeq2 from Audio Damage to the source file above. Once again, the values were requested without conveying to the contributors which parameters they governed. The table below illustrates how the values were applied:

Parameter	Request	Received	Contributor
Preset	1-40	25	@alka
VCA Step Size	4, 8, 16 or 32	4	@BlueEydGlambert
VCA Gate	1-100	43	@dust_bunnies
VCA Decay	1-70	36	@fbish
Filter Type	1-6	5	@groovecriminals
Filter Frequency	40-2000	1688	@heuristicmusic
Filter Resonance	0-100	76	@HipGnosis13
Delay Time	1-8	8	@leeconnolly
Delay Feedback	0-100	37	@LucidAcid
Delay Send	1-100	40	@madebyrobot
Bit Rate	1-100	89	@PublicSpacesLab
Bit Depth	8-24	19	@pure_tone
Distort Fuzz	0-20	15	@retorta
Distort Warp	0-20	17	@ronsens

Thank you to all the contributors. That’s my bit done. Now it’s over to you, F.
