acid test
generative acid basslines.
lately I've been listening to acid house music and thinking about markov chains. previously I used markov chains to make a jazz piano accompaniment. it seemed to me that acid house basslines might be amenable to applying stateless logic for generating believable sequences. whether this results in "believable" acid music is up to you, but worth it for me to give it a try.

this script started off as a literal "test" to do A/B explorations on different meta-parameters of the markov chains, but its too slow to sample parameter space by listening. so instead, I decided that the markov chains might be intuitive enough to edit directly, and I added controls to edit each individual markov chain. the output can be sent to midi, crow, or the builtin engine. the builtin engine is forked from bernhard's sc code which itself is forked from by_otophilia's code for a 303 emulator in SuperCollider.
Requirements
- norns
- midi (optional)
- crow (optional)
Use it
Start the bridge with this driver; it forwards named OSC commands to the software:
Then send OSC to 127.0.0.1:7777, for example:
From Claude or any MCP client, the osc-bridge mcp server exposes this driver as norns_acid_test: ask “what can the Monome norns do?” and it reads this map with list_routes. See the MCP guide.

The same MIDI as norns.vendor.fw-2.9.4, which this firmware shares.
Limitations
Source: the Lua source of the norns script acid-test by infinitedigits (schollz/acid-test at ad3e2f9), listed in norns.community. Shares the norns system OSC of monome/norns.vendor.fw-2.9.4 (port 10111, /param, /remote): give the norns' IP address as host override. Its own routes are the 18 parameter(s) whose id is written out in its source, read without running it, with range, options and default when written out too; set them while the script runs on the norns. 7 parameter call(s) could not be read without running the script (ids built at run time, values from variables) and are not mapped: reach them with the base driver's /param/{id}. Parameters added by libraries or engines outside the repository are not mapped either. A value goes in the parameter's units (an option's index from 1). MIDI is not mapped: the script's MIDI handling is its own and parameter MIDI mappings are learned by each user (PMAP). Untested on hardware.

Frequently asked questions
Can an AI agent like Claude control the Monome norns?
Yes: SynthHub's hosted MCP server knows the Monome norns's MIDI map, and its browser relay lets the agent send it parameter changes or load a sound, each sound change confirmed by you.
