Lpd8 4 samples and 4 synths (2)

Performances, Streams & Live Coding
1

Hi.

Last few weeks, I’ve been trying to use sonic pi to squeeze maximum control out of one lpd8. It’s not finished, it will always be a work in progress. It’s not a performance, nor a stream and I’m even actively taking the ‘live’ out of ‘live coding’. It might be useful to someone, somewhere, someday so I’ll post my best shot so far here anyway.
