"it starts as a simple 3 note 4 bar matrix 1000 patch #220 and that patch and sequence stays the same throughout, the only variations after that is from the filter, it ends with the basic patch one more time, I threw in a simple drum for interest too
the warp 9 is a mono 2 pole filter so it does not self resonate but there are some features that make it very attractive
the filter envelope can be triggered by a midi note on signal (or audio signal if you prefer) so you can control triggers with a sequence, then you can very the trigger patterns and the LFO recycle can also be linked to the triggers on varying combinations, there are a variety of LFO shapes, algorithms and a sample and hold
from there it goes to stage two where you control cutoff, resonance and modulation strength and you can throw in some distortion of you want ( I rarely do)
in the demo I got it going and then tweeked a few parameters - kinda nice IMHO, this thing can make the matrix 1000 a lot more interesting
best part is there are 32 memory slots so when you get a good filter set up you can save it all and recall it later - way cool , and it will transit knob movements out to midi of you want to take it that far
the negatives are that each knob is used for three different parameters so it is quite confusing, the patch ids are also in binary light combinations not in numbers, blecch
all in all this has been the hardest piece in my rig to learn to control but I,m getting it"

sweet petey garbage synth

"all chips and capacitors were pulled from dead electronics pcbs laying around.
the 3372 was pulled from my chroma polaris that went bad years ago (you do the membrane upgrade,
not me). - so vco / noise/vc mixer/vcf/vca with the asm-1 lfo and ian fritz’ ad/ar circuit. the vco is rene’s 4069 VCO - the noise is gravenhorst’s PIC based digital noise - which i had in another unit that i took apart. noise enters the synth through the VCO’s pulse width input via a pushpull pot/switch (pot is pitch)"
