chord quantization bug
#5
I had a go at recording the output of the NDLR into Bitwig (I'm more of an out of the box guy, who also happens to own a Deluge Smile). In all my tests I had the NDLR connected to my Windows PC over USB and Bitwig was the master clock at 60BPM. The chord sequencer was set up to output the same chord every bar (4.0 x 1/4 notes) and I recorded the pad. Pad quantize was set to 1/4 notes on the NDLR.

There were some interesting variations in the timing. 
  • The notes in first chord recorded were consistently longer than any subsequent chords. Bitwig seems to display note lengths as bars.quarter.quarter-quarter.fraction down to 1/100th of a 16th note. The first chord length is always > 1 bar (usually 1.0.0.20 or 1/5 of a 16th note longer).

  • Any chords after the first are mostly 0.3.3.98 or 1/50 of a 16th note shorter than a bar. 

  • The start point of each chord after the first would drift backwards from 0.2 16th notes past the start of the bar but then occasional longer chords would push it forwards again so that the start time wandered between 0.1 and 0.2.

  • Whenever I recorded I also saw a 0.27 of a 16th note delay before the first chord started. I'm guessing that this could be latency in my system so I've ignored it for the above.
I hope this is useful. These aren't massive numbers (1/5 of a 16th note at 60 BPM is 12.5 milliseconds) but as that's nearly a 1/64th note it may explain why the Deluge displays the first chord as an extra step longer when zoomed in.
