Thanks for the suggestion. I don't have a proper sample and hold at the moment but I have a doepfer a-156 quantizer. Rereading your suggestion, I wonder however if I used the correct term when I said ghost notes. Actually what's happening is that I hear the notes whose gates have been turned off when my envelope has mor than the slightest decay time.
My muxlicer being scaled to 10v I've found that I can "turn off" gates by pushing my notes beyond the audio range. Obviously it's less practical.
I'm really up in the air about keeping this module : I'd been awaiting its release but think now that maybe I misunderstood what it's about. I'm looking for a way to mute notes.

It seems to work best with very snappy envelopes otherwise you get ghost notes which can be interesting but that's not the reason I purchased this module. The demo by synth diy guy used a percall.
If you have a sample&hold available you can use that to avoid the ghost notes. Just sample the pitch CV when the gate fires and route the output of the S&H to the V/O input.
I always have a quantiser with build-in S&H before my oscillators. Makes it easy to use independent pitch / gate sources.
I may be misunderstanding your issue but it seems to me that you're looking to create rests in your sequence? And you can't do that because you always hear the next note coming in (using anything other than a very short envelope)?
My advice would be to separate out thinking about "gates" (the pulses that it produces from gate/clock outs, and which trigggers your envelope for a VCA) and "pitch cv" (a continuous stream of cv that comes out of mux io)
Gates: There are a few ways to "silence" or skip gates on Muxlicer but none are very straightforward. You can:
- Use cv to address the "gate mode" input (low cv will silence the gate, high cv will create a ratcheting effect)
- taking the per step gates out you want and mix them.
- take the per step gate out you want silenced, invert and offset it, and use this to open and close a VCA through which you run the "all gates" pattern.
None of these are very practical for a simple use case, which I guess is why they made the Mex expander - it gives you a much easier way to adjust your gate patterns.
Now onto Pitch CV: Even if you get the gate pattern you want, you're still going to hear unwanted notes in your sequence with longer envelopes as you described. That's because unpatched the Muxlicer is literally just going to continously emit the cv pitch pattern that you've set the sliders to.
Like previous poster said, this is exactly what a sample and hold module is for. A quantiser is something else entirely and
won't help you here
Edit: Apologies I should have checked earlier, but I think your quantiser takes a trigger in, so it will solve your problem.
A sample and hold will take a) your chosen gate pattern b) your pitch cv. When it gets a gate or trigger pulse it will grab whatever the pitch cv is at that exact time, and hold it steady until it gets the next gate/trigger. It will ignore any notes changes inbetween, you'll be able to use envelopes of whatever length you like (until you get to your next gate and the pitch changes again)
The awesome thing about this I'd that if you have 2 different sample and holds and trigger sequences you can use that to derive different patterns from the same pitch cv.
Edit: all of this applies to your quantiser as well, plus you'll get the signal quantised however you like. Just make sure you trigger your quantiser with an appropriate gate pattern.
Hope this helps.
