Description
Seq writes two voices, a bass and a lead, that follow a chord progression, and adds four drum trigger parts. The repository has a chord-to-MIDI core, a Launchpad driver and MIDI output code, and its README is two lines long; the details are in the manual on the Alchemy Lab project page. The only release is an early build that the author says has not been run on a module and was tested on a computer and in an emulator. It carries the same SD-card firmware picker as the author's other Alchemy Lab firmwares. Hermetic Modular did not write or endorse it.
Install notes
Copy seq_alchemy.bin into the /alchemy folder of the module's microSD card and switch to it from the SD picker of a family firmware that is already running (hold B2 and B3 for two seconds, then B1). The first time, flash one family firmware from Hermetic's web programmer. The release is an untested early build, so expect rough edges.
