I’ve updated the Arduino code from my previous post here to add a very crude form of swing to the Volca sync beat.
Unfortunately it can’t do real swing as the Volcas currently take 1/8th note sync signals and have 1/16th note sequencers.
The code just changes every other beat signal to vary by a set percentage. This can be positive, making the first two beats slower or negative making the first two beats faster.
You can see a demonstration here.
