After much experimentation, I haven't been able to quite get the sidechain effect on the op1 I've been chasing. Here's where I'm at; maybe someone will find this helpful or be able to enlighten me.
My approach of choice has been to use element LFO with "input" as source, then split the output with a splitter cable, and send a drum track off tape while muting a recording channel with a bass sound (sequenced or just guesswork, as you can't hear it while you're muted obvsly)... Apply the LFO adding numbers to the hpf in nitro, or to the S in the adSr envelope for long sustained bass notes.
The main issue seems to be that there is no release control on this ghetto-rigged side chain gater/blinds effect. Without release, the LFO is too fast, and seems to create too many artifacts... I dig artifacts, but I don't really want them here.
Anyone have more luck? You can get some more convincing side chain effects manually, but I'd really love to automate it.
