Mozaic MIDI Interception

	MIDI Reception and Intervention
	• MIDI Input Handling:
	• Mozaic triggers the @OnMidiInput event when any MIDI data is received.
	• Note: Incoming MIDI is not automatically forwarded to the output—you must explicitly forward it using commands like SendMIDIThru or SendMIDIThruOnCh <channel>.
	• Forwarding MIDI Data:
	• Use SendMIDIThru to pass all incoming MIDI data unchanged.
	• Use SendMIDIThruOnCh <channel> to reassign all incoming MIDI to a specific channel (e.g., SendMIDIThruOnCh 9 routes everything to channel 9).
	• Filtering MIDI Events:
	• The variable MIDICommand holds the last received MIDI command (e.g., Note On 0x90, Note Off 0x80, CC 0xB0).
	• Mozaic supports both hexadecimal (e.g., 0xB0) and decimal (e.g., 176) notation.

kmorrill / Mozaic gotchas

Last active February 2, 2025 16:25

	Below is a cheat sheet highlighting Mozaic’s key differences, limitations, and “gotchas” relative to typical coding or scripting languages. If you’re guiding other LLMs (or developers) who want to generate code for Mozaic, these are some of the most important points to emphasize.

	1. Limited String Handling

	No string variables: Mozaic doesn’t allow you to store strings in variables.
	Cannot do string interpolation: You must log strings as constants in braces (e.g., Log {Hello}), or log numeric variables separately (e.g., Log var).
	No concatenation: There is no built-in method to build dynamic strings.
	Gotcha: This means you can’t do myString = "Hello " + name or myString = {"Hello "}{name} in Mozaic. You also cannot store a string from user input in a variable.

	2. Unique Event Model with Labelled Blocks

Mozaic OP-XY Melody Generator

	@Description
	Melodic Generator v2.0
	Uses four knobs to control melodic generation:
	- Melodic Contour: Smooth ↔ Angular intervals
	- Rhythm: Steady ↔ Syncopated patterns
	- Register: Narrow ↔ Wide pitch range
	- Harmony: Sparse ↔ Rich note choices

	Adjust any knob to generate a new melody.
	@End

Mozaic OP-XY Drum Generator

	@Description
	OP-XY Drum Pattern Generator v2.0

	A dynamic drum pattern generator for OP-XY creating musical 4-bar patterns.
	Controls:
	- Density: Overall number of hits (sparse to busy)
	- Variation: Pattern unpredictability and dynamics
	- Balance: Emphasis between core drums vs percussion
	- Repetition: Pattern evolution over time
