Here’s my attempt at making an LPG that allows for a few useful adjustments.
The “vactrol ring” and “CV Both” are using a sample of the lower part of actual Make Noise LxD’s vactrol response on a +10v offset when strike is triggered — to achieve exponential envelope.
It’s pretty simple but i’m sure i’ll be improving it.
CV Both — equivalent to level control on Optomix or Terminal (VCA/VCF open/close). It is mapped to the reversed vactrol response sample to make it exponential, like on most LPGs.
Strike — feed it triggers / gates.
Damping — controls the speed of the vactrol response sample playback, effectively affecting the “ring” time. 0 is original speed (that seems too long-ish).
VCA Bias and VCF Bias — offsets tuning the response to make it brighter, darker, more “VCA-y” or more “VCF-y”. Experiment! I picked up ranges that seem useful to me but you can always “Edit Controls”.
VCF Q — filter resonance. Again, I limited ranges to what seemed useful to me.
put the .unit file anywhere
the “vactrol” folder goes into “ER-301/samples” folder in the root of the SD card.
Again, the path should be "/ER-301/samples/vactrol"
CPU level is at 13% now, i’ll think about what I can do to reduce it.
please let me know what you think! i was able to coax pretty convincing LPG stuff from it.
