Trinket

Trinket is MIDI performance software. It allows a musician to create and modify MIDI data in real time.

For more information see the wiki. [TODO]

Pipes

Most pipes take MIDI input from some pipe, do something to it, and output it to another pipe.

Some pipes generate MIDI data, so they don't have an input. Some pipes output MIDI data to a PortMidi port, so they don't have an output to any other pipe.

Input

Gets its input from a PortMidi port.

Output

Sends its input to a PortMidi output.

Fan

Copies its input to one or more pipes. This is the only pipe that has multiple outputs.

Transpose

If the incoming message is a note message (note on, note off, or polyphonic pressure), it transposes the note number by a specified amount.

All other messages are passed through unchanged.

Range

If the incoming message is a note message (note on, note off, or polyphonic pressure), it passes them through only if they are within the specified low and high notes. Note messages that are lower or higher are dropped.

All other messages are passed through unchanged.

Channel Remap

Remaps MIDI channels. Any channel can be remapped to another or filtered out.

Transform

Transforms one kind of MIDI message into another.

Clock

Has a BPM setting (beats per minute) and sends out a MIDI CLOCK message 24 times per beat.

Source Message Types

• Note on value
• Note on velocity
• Controller
• Program change
• Channel pressure
• Start, continue, stop

Destination Message Types

• Controller
• Program change
• Channel pressure
• Start, continue, stop

TODO: write about how the more odd mappings, like start -> controller, are handled.
