Inspired by Turing Machine, Fugue Machine, and Physical (Norns Study 4)
This sequencer was originally written in November of 2018, but had not been updated for Norns 2.0 compatibility
ground_state updated it to 2.0 in early 2020 and added audio output via Molly the Poly -> I’m Super grateful to this community member for updating the script, adding some new features and cleaning up my bad code
justmat also added the ability to output to Crow (Just Friends and CV) and helped us implement some new features
requirements
Grid, MIDI Interface required to output MIDI (optional), Crow (optional)
features
Global tempo, tonic and scale
There are 4 independent tracks of 1-16 steps
Each MIDI track is sent to the channel equal to the track number
Each track has a tempo modifier (1 is global bpm, 8 is global bpm divided by 8)
Each track has a dispersion parameter (1 is a tight dispersion of notes, 10 is a very high dispersion of notes)
Each track has a randomization parameter (1 is locked sequence, 8 is completely random)
Each track has a rest frequency parameter (1 is no rests, 8 is no notes)
Each track can be muted
Each track can be copied and pasted into another track
Each track can be transposed up or down a scale degree
Each track can be shifted forward or backward one step
Each track can be inverted or reversed
All tracks can be locked or cleared simultaneously
Tracks can be re-synced if tempo modification un-syncs them
documentation
There are 5 pages in total, a settings page and 4 track pages
After launching the script, the track page for Track One will be visible and the sequencer will be paused
The bottom row is always the toolbar: pause, mutes for tracks 1-4, lock all, clear all, select tracks 1-4, and settings page
The LED in the bottom right corner toggles between the current track page and the settings page
The LED in the bottom left corner toggles the sequencer pause
On the settings page, the eight buttons in rows 5-6, cols 13-16 are currently unassigned
For now, pressing any of these LEDs will re-sync all sequences
Hold Key 3 on the Norns to see the midi notes in the sequence for the current track
