As a result of discussion in this thread, I’ve made a pretty functional granular synthesis instrument in renoise using phrases and the sxx command to trigger sample slices. It has some quirks and limitations, certainly, but is a good start toward native granular synthesis in renoise. Check it out here:
Version 1 has linear playheads, while version 2 has more randomized, “swarming” playheads, a different sample, and slightly different macros
Read the comments when it opens, drop in a sample, and experiment!
There are 12 different playheads per phrase. 3 playing start to end, 3 playing end to start, 4 random, and 2 ping-pong playheads. Playheads must be manually enabled/disabled in individual phrases if you want to use different ones. This is done by muting/unmuting the note columns in each phrase. Each column is labeled with its functionality.
Happy to answer any questions in this thread if anyone has any.
