Stereo Tremolo - Fixed

Post by Digital Larry » Sun Apr 21, 2013 9:17 am

This one uses a Ring Modulator patch I found on the forum here.

One is in the left channel and one is in the right channel. I made the ring mod LFO factor 0.001 on both sides so you don't really get into ring mod territory even with the LFO speed turned all the way up.

POT0 is the left LFO speed and POT1 is the right LFO speed.

You may get no sound initially if the pots are all the way to the left.

This is a cool patch especially with stereo out as you get some weird rhythmic patterns going on from the different LFOs.

I've added some comments below to show you where you could adjust the left and right max LFO speeds. Note the minus sign!

Edit: This is stereo in - stereo out.

Code: Select all

SKP RUN,3
WRAX 33,0.0
SOF 0.0,-1.0
WRAX 34,0.0
RDAX 33,0.001     ; change this factor (and the one below) to set the max left LFO speed
MULX 16
RDAX 34,1.0
WRAX 34,-0.001  ; change together with the one above
MULX 16
RDAX 33,1.0
WRAX 33,1.0
MULX 20
WRAX 32,0.0
SKP RUN,3
WRAX 36,0.0
SOF 0.0,-1.0
WRAX 37,0.0
RDAX 36,0.001  ; change this factor (and the one below) to set the max right LFO speed
MULX 17
RDAX 37,1.0
WRAX 37,-0.001 ; right LFO speed factor
MULX 17
RDAX 36,1.0
WRAX 36,1.0
MULX 21
WRAX 35,0.0
RDAX 32,1.0
