a norns script to sequence rows of beats with samples.

abacus

sequence rows of beats with samples.

this norns script creates sequences of samples from a tape. you can load any tape and splice it into up to 26 samples (named a-z). samples can then be patterned into 16-subdivided measures. patterns can then be chained together.

this script was a hard one to make because at a certain point i kept getting caught up playing with for hours instead of figuring out how to make it user-friendly...

this script builds off others. it is inspired a lot from ideas in glitchlets (no realtime here) and a lot of code ideas from @mattbiddulph's exquisite beets (initially i forked beets but i didn't want to ruin the code with my hacks). also inspiration from the po-33. and, it is inspired by @csboling's beautiful waveform renderings.

future directions:

• fix all the 🐛🐛🐛
• add individual parameters for samples
• add play trigger

Requirements

• norns (version 201023+)

demo

my other norns

• barcode: replays a buffer six times, at different levels & pans & rates & positions, modulated by lfos on every parameter.
• blndr: a quantized delay with time morphing
• clcks: a tempo-locked repeater
• oooooo: digital tape loops
• piwip: play instruments while instruments play.
• glitchlets: add glitching to everything.

Possible Lock up

Here is a possible reproducible lockup

Make a pattern, make a chain, start running
Go to chain page, set focus chain, single pattern chain, change the single pattern in the chain, as you change it the chain will continue and play the selected single pattern. scroll before pattern 1 to "empty" and it stops. However you cannot seem to start it up again or move to other pages.

effect rate doesn't match global rate
