Now I am confused too, have to be really careful with naming conventions otherwise it gets really confusing!
If you have a gate and a CV coming into the ER-301 as well as using the gate to trigger an envelope or whatever, you could also use the same gate input to trigger a S&H unit that is placed in-between the incoming CV and wherever you’re sending it.
And hey, the ER-301 is a pretty spiffing module, I can totally understand the obsession. I may well buy one one day. (And I do have a really neat idea for a control surface to code up on the Monone Ansible for it…)
Really really sorry for the slow feedback on this (have a young baby, modular time comes in fits and starts).
(This is based on firmware v2.16.)
Based on a bit of testing, it looks like it’s doing an inverted track and hold.
Thus when the track gate is high, the mod CV is sampled, but when the gate is low, the mod CV is passed through.
This causes an issue with release times on envelopes. If I’ve set up an LFO into a mod CV, and that in turn is modifying CV A, which is connected to VCO pitch. When the gate goes high, the input is sampled and I get just a single note, but when the gate goes low, the LFO directly modulates the VCO pitch, causing a warble in the release of the note.
(If that doesn’t make sense, I can type up a more detailed example.)
If possible I would like it to behave as follows, when the track gate is high the mod CV is sampled, when the track gate goes low, nothing should happen, the previously sampled value should still be current.
