Ben,
Thanks for reaching out about these issues.
As far as I can recall (it’s been a while since I looked at this code), I do think that the RATE is a saved parameter in the presets. When this happens, does it sound like the saved rate is a multiple of the intended rate?…In other words, is it being multiplied by the multiplier knob? That’s the only thing that I can think of that might be part of this issue.
The idea of having the assigned expression parameter saved in the preset is a really good idea. I can’t believe that we didn’t think of this earlier. I will add this to our change log for the next update. Thank you for the suggestion.
I think in our latest version of the Quaverato software we implemented your third suggestion. In this latest version we have the bypass function split across the data range…0-63 is on (or off, I can’t remember at the moment) and 64-127 is off (or on).
In this latest version of the code we also made updates to the tap time functionality, which keeps the tempo from drifting over time as much. We actually haven’t put this version of the software into production yet, but I can send you the hex file if you want to install it on your pedal. You’ll need a USBtiny ISP programmer and a PC.
I don’t know that we’d be able to update the code anytime soon to adapt the other change you suggested, because our software guy is on an extended break, but I will put it in the future change log.
Thank you for your suggestions. Please let me know if you want that hex file to update your pedal.
