https://www.muffwiggler.com/forum/postin...&p=3175676
"Only a partial quantity of the first batch had 12bit DACs. The rest of the batch had 16bit and the next/subsequent batches will have 16bit as well.
The 12bit DACs actually worked great and you would be hard pressed to hear a difference between the 12bit and 16bit when used as envelopes/LFOs. They are clocked at 48Khz so it is very fast update rate.
The only issue was some aliasing due to quantization error noise that could be faintly heard in the 12bit version. This issue was mitigated with a software update that employed a special form of dithering."
Actually, quantization, could be. Refresh rate, could be. Aliasing, not here since the envelopes are not sampled signals.
If everyone stays gentle, then I will take a deeper look into it after the release.
Regarding the envelopes. I think it's in the decay stage. In one shot mode and cycle modes the blip is most pronounced and harder to dial out. In one shot mode, much longer decay times seem to dial it out, but I can't dial it out in loop mode. I tried this will all 4 VCA's on my Intellijel Quad VCA. Same result in each VCA. I used a sine wave as the signal into the VCA. Headphones. I'll post the project file. Stay tuned.
For the quantization, your detailed response:
"Empty table, loop, resync, whatever, that doesn't really matter.
Speed 1
Source internal tick or time(better)
Choose your notes
Quantization to either UP or DOWN
Actually, the most easy configuration you can think about. I tested that today again, it works. "
Worked great! Thank you.
What I was doing before wasn't working for me before because I had speed to 6, because I thought the table speed needed to align with the the pattern steps, causing the gated quarter note to quantize on every step. It makes sense now. I'm learning! Thank you.
here is my project file. I use a different envelope on each track and then just smash keys on my midi controller with the midi channel assigned to the relevant track. Midi ch 1 -> track 1, Midi ch 2 -> track 2, etc etc.
track one has my quantization test on it.
Use a sine wave for the signal and listen through headphones for the blip in the (decay stage?) of the envelope. I think I have the blip dialed out on the ADSR type on track 4... for comparison.

Allright, I think I get what you mean. Your first sequence actually keeps on retriggering. That gets a wobbly effect.
As for the rest, what i hear are quantization artifacts with fast 'curves'. These are related to the refresh rate of the envelope (and so higher voltage jumps).
I think there is room for improvement for sure. But this will be after the next update.
I also see that you also put them into automators. That is never necessary for envelopes except for if you want to run them through automators for some special effects.

I thought the automator had to be engaged (play button on) for the envelope to work. Good to know I can skip that step.
Thanks.
