1v/o tracking consistency #14

Closed seanrieger closed 7 years ago

seanrieger commented 7 years ago

Okay, I'm not sure this is a legitimate bug, but I thought I would add as an issue to see if anyone else is seeing the same behavior. When I am using 1v/o I'm getting some note jumping that reminds me of a quantizer that is having trouble tracking. I tried it through multiple gates and CV's (KeyStep, PM Midi to CV and Mother 32 Midi to CV) and get some interesting results. I grabbed a video here (link is not public) https://youtu.be/D8QZ4tc--LA if that helps. Am I just hammering the internal quantizer too fast?

Config - I tried two ways, both below::

crossfade=0 crossfadeTime=25 showMeter=1 meterHide=2000 chanPotImmediate=1 chanCVImmediate=1 startPotImmediate=0 startCVImmediate=0 startCVDivider=2 looping=1 sort=1 pitchMode=1 anyAudioFiles=1

Same results with this config

crossfade=0 crossfadeTime=25 showMeter=1 meterHide=2000 chanPotImmediate=1 chanCVImmediate=1 startPotImmediate=0 startCVImmediate=0 startCVDivider=0 looping=1 sort=1 pitchMode=1 anyAudioFiles=0

Thanks for the video, makes it really clear. I'll do some testing today.

Looks like the CVs are right on the edges of the quantized values so I might have to shift them half a note along so they land in the middle.

Can you try Alpha 7 please. https://github.com/Normalised/RadioMusic/releases/tag/v2017-alpha.7

I smoothed the inputs when quantising and made it less sensitive around the note boundaries.

I tested with a midi keyboard -> Bitwig -> Expert Sleepers ES-3 and with Alpha 6 I was getting similar results to you. Alpha 7 was very consistent for me when playing from keys.

Huge improvement. Very consistent on Alpha 7, Nice work! Thank you.
