JS Arpeggiator Timing Issue (& the fix) (FIXED)

IDDQDSound · 08-22-2022, 03:11 PM

Hey folks!

I always felt the stock JS Arpeggiator to be overly "humanized" in high speeds. The notes don't play 16ths but rather introduce an ever-shifting amount of "swing" to the rhythm.

In a recent livestream we went over the code with the awesome leafac and discovered this line at the end of the JS plugin:

//spos+=1

This line seems to have been commented out, perhaps on accident. Uncommenting the line so it looks like this:

spos+=1

fixes the issue completely and all notes are played perfectly in time!

This is (As far as I understand) probably due to the fact that MIDI in JSFX is processed in the @block section which may or may not be a whole integer ratio of the tempo, causing these timing issues.

Anyway, it's a simple fix but I thought it could go in the next update either way!
