@any1particular- since you asked...I've set up the description of how I got this sound (best as i can "reverse engineer" my Ableton Live 7 set up...):
1 - put drumloop in audio track
2 - added hematohm and set up some presets.
3 - Ohmforce plugs have a "time" parameter. This time parameter describes in seconds, how long to take to morph from on preset to another. Also- most hosts can record aLL the automation while changing from one preset to the next.
so... once I had my hematohm presets created, I copied several back to back instances of the loop into Live's Arrangement view, set hematohm's "time" to 3 seconds, armed the global record button in Live, hit play, then I changed presets.
4 - Once I was happy with my hematohm "pass", I added Ohmboyz and repeated the above process (created presets, armed record and changed Ohmboyz presets)
5 - now, I have a pretty interesting sounding soup, but to make things a little more interesting, I resampled 11 2 bar clips from that original hematohm/Ohmboyz pass.
6 - i then set the 11 clips in their own audio track In session view. i then set up a series of *legato* follow actions so that these clips would switch from one to the next randomly every bar. We'll call this the "random track"
7 - next, I resampled the "random track" and used that 36 bars back to back 4 times (= length of the piece) This is the only portion of the piece that actually sounds the same each time
8 - positioned the panning of the random track and the track in step 7 at about 10 and 2 o'clock.
9 - sent the output from "random track" to another open audio track. Sent that output to a MIDI track on which I load MST ReSynFX (that instrument resynthesizes it's audio input in realtime. Much fun to be had there!)
10- set the input of an open audio track to receive the output of the feed from "random track". the OUTPUT of that track was sent to the input of a midi track where I loaded Expert Sleeper's CrossFade Loop Synth. I have also used Live's Scale Midi plug to react only to octaves so that the "pitches" that the loop synth spits out are always rhythmically compatible (ie .25, .5, 1, 2, etc= midi octaves divide or multiply the original plybk time by these numbers)
11- sent the output of the Crossfade Loop Synth to open audio track
12- to the audio track being fed by CrossFade Loop Synth output, I added Ohmygod,Ohmicide,UHBIK-F(beta), Live fx rack with 4 instances of Grain Delay (all instances MIDI'd to PitchBend controller so that the input could be pitched up or down 3 octaves...), MFM2, and byd-Sinnister(agressive compression)
13- added 2 midi tracks: one to control Ohmygod set to Poly mode and the other midi track to control the Melohman option in Ohmicide (set Melohman to "all octaves). I wrote a patch that "tuned" decimation distortions to the pitch of the audio input from normal scaled instruments (it's "SynthBBDecimation.pbk" if you own the plug...pretty kniffty, if I do say so me self
)so...as you may be able to tell from this rambly dissection- It's a pretty CPU intensive set up. Or at least it's a tad complex on the routings- but that is the beauty of Live: once you get used to the way it accomodates things, routings are not so much a problem (it becomes more of a chore to get it all on one screen!)
while the above description is probably not as informative as a youtube vid, it's the best I can manage... and speaking of which- If you ARE a Live user, there are lots of cool vids with neat tips and tricks on youtube if you have the time an inclination
[edits for clarity...if you can believe that]
you'll see, part 2 forward is a bit more informative
