m4l-KeyStepper
A manually-advanced variable-length step sequencer.
This is a Max For Live step sequencer that advances on note-on events and supports loop lengths of 1 to 32 steps. This gives you the ability to easily create polyrhythms and interesting time-shifting variations. Each step can hold a pitch (relative or absolute), velocity, and note probability. This allows you to really go hog on generative music.

- v7 - 2024-10-29 - Add non-blocking telemetry ping on load. Does not send any identifying information, only the plugin name, the local computer name, type of computer, and CPU type. I just want to see which plugins are used the most.
- v6 - 2024-10-17 - Fix bug that prevented presets from being loaded with the Live Set.
- v5 - 2024-09-14 - Re-implement JS code in TypeScript with m4l-typescript-base. No user-visible changes.
- v4 - 2024-08-09 - Add preset capability.
- v3 - 2024-02-05 - Fixed problem with multiple instances in one set. Thanks @Michaelknubben!
- v2 - 2023-10-21 - Fixed undo buffer pollution bug. Rookie move.
- v1 - 2023-09-09 - Initial release.
Installation / Setup
If you just want to download and install the device, then go to the Releases page and download the newest .amxd file there. You can also download it directly via the links in Changelog.
Usage
Add the device to an instrument or MIDI track. Each note you send to the KeyStepper will advance its step.
Steps
Use the Steps dial to control the number of steps in your pattern.
Reset
Press the Reset button to return to the first step in the pattern.
Pitch Mode
You can toggle between Relative and Absolute pitch mode. In Relative mode, the incoming note is shifted by the distance that the step's note is from middle C. In Absolute mode, the note that is emitted is the step's note.
Note Velocity
The velocity slider in the device controls how much to shift the velocity of the outgoing note, positive or negative. With the velocity sliders in the middle of their travel, the incoming velocity will not be affected.
Note Probability
Each step in the pattern can have a probability of playing a note. This allows you to create ever-different patterns that still have a structure. Set the probability to zero to disable a step entirely.
Development
This project utilizes m4l-typescript-base for building the TypeScript file(s) into Javascript. See the documentation in that repo for details on how the system works and how to work with it.
