Pentrandom

this is a midi effect, it doesn't produce sound on its own, but it can be hooked into another patcher to send notes to other synths
Pentrandom is a random arp generator with probability setting, it sends random notes from pentatonic scale (major/minor - toggleable)
you can adjust note length, probability, or velocity randomness

not much but it's p fun to play with
in the demo, background arp and the lead were using Pentrandom
