I’ve discovered Befaco’s Slew has admirably extended times for my usage, but since the sliders are calibrated in abstract 0-1.0 increments, I have no idea how to dial in exact slew times other than by tedious trial and error.
BogAudio’s Slew only goes to 10 seconds, unfortunately. I’m looking in the range of 10-60 seconds.
Also, the VCV Fundamental PROCESS maxes out at 10,000 ms / V, which also equates to 100 seconds for 10 volts, though I’m not sure how accurate the timing is. I believe it is reproducible, but may not be exact. I did a rough test, and it seemed to take ~110 seconds to reach 10V.
Ouch! I just tested the Bogaudio SLEW on my MacBook Air, and it seems to struggle at the extreme slow settings if the voltage is at or near 0 or 10 volts - it stalls If I reduce the time to say 5 (50 seconds / 10V), then it starts moving, and then I can increase the rate. Well that will not work.
So it looks to me like VCV PROCESS is a better bet.
This is with 16-voice polyphony for a 45 second linear slope (from 0V to 10V). Well, almost 45 seconds with the Befaco module because, like the OP stated, there’s some tedious trial and error to be had.
Befaco keeps a steady CPU consumption below 1% whereas BGA Slew fluctuates aplenty but seems to average around 5%.
So when I’m working on patches hovering above 80%, these are the kinds of economy I’m looking for
I figured out the problem! It fails at 10 (100s) for me as well on my Windows machine.
But I am running both at 96kHz.
If I set the VCV sample rate to 48kHz or lower, then all is well with Bogaudio. But if I set the sample rate to 192kHZ then Bogaudio doesn’t even work a 5 (50s). When I get a moment I will try to look at the code to see if I can find a limitation inherent to the algorithm and/or data types he is using.
