Not sure if anyone else has come up with or shared this recipe, but I just figured out this trick to do ratcheting on an external synth via CV/gate and I figured other people would get some use from it. It’s a twist on the standard CV/Gate pair where you replace the gate channel with a VALUE LIN channel and “fake” the gate pulse using a square wave LFO. The main downside is that you lose the ability to set note length, but if you’re doing anything with ratcheting you’re likely using short note durations anyway.
Take your normal gate channel and change it to LIN
On the LFO page for the channel set:
• SPD to 63
• MUL to x16
• WAV to SQR
• MOD to ONE
• DST to VAL
• DEP to 127
This makes it so that a 1/16th note square wave pulse is sent every time a note is triggered (1/32nd high, 1/32nd low).
Now, enter steps in record mode like you normally would, but to get a step to “ratchet” you need to P-Lock the LFO MOD to TRG and LFO MUL to whatever rate you want for the ratchet. You can also mess with LFO SPD to get odd ratchet values.
