Yeah, I was thinking about this, too. Not entirely sure how it could be done (a gate is delayed, but not ignored, until there’s a zero crossing) but I’m sure one of these guys will come up with a solution
Hello. I’m hoping someone can help me figure out what I might be doing wrong or correct any misunderstandings I may have.
I’ve been searching for way to trigger and envelope 808 style bass drums on the 301 that don’t have a click at the beginning (actually any sound, but low bass is where this problem stands out most). If I use an envelope that is shorter than the time between triggers then I’m fine, but hopefully you can understand why that is not ideal.
So far the best solution I’ve come up with is to use an external envelope that can reset to 0 on receiving a rising edge no matter what (O_C in Piqued mode - but then there goes my damn quantizer). That solution isn’t perfect but it’s much better than an analog style envelope that picks up wherever it left off in the decay/release phase, but these resetting envelopes are a little harder to find (and again, it’s not a perfect solution).
So, I was thinking this kind of ZCD VCA is a solution for this problem? Is that the main purpose? To ensure clicks don’t arise? And that this S&H solution, though it will introduce stair-casing, that stair-casing should not have an audible impact? This is where I think I’m missing a step, but I’m getting super audible “zippering” - if that’s the correct term.
Here are some screens of what I have pieced together from patch notes earlier in the thread:
Top - “Env” is Linear Bipolar VCA:
Env (VCA) level subchain - A1 source is my external envelope
S&H trigger subchain
Here is an audio example of what I’m experiencing. The first two events are a sampled bass drum with an envelope that runs its course (so long enough for decay to reach zero before triggering the second time). After that is the same sound being re-triggered fast enough to produce clicks, and finally the same thing only use what I think is the S&H method.
Actually the “zippering” sounds kind of cool, but not for my bass drum purposes. What did I miss?
