Clamps Overview

Currently Clamps supports two MIDI APIs, :jackmidi (the default) and :portmidi. Both APIs can get used simultaneously. In order to enable jackmidi, the file ~/.incudinerc needs to contain the following line:

(setq *enable-jack-midi* t)

When using portmidi, add the following lines to ~/.incudinerc:

(setq *enable-portmidi-output-sample-offset* t)
(setq *midi-input-timeout* 8)

As both APIs can be used simultaneously in Clamps or Incudine, all of the above three lines can be added to ~/.incudinerc without any problems.

When starting Clamps, the default MIDI API used on startup can be set in the Clamps init file. For :jackmidi, add the following line to ~/.clampsinit.lisp:

(setf *default-midi-api* :jackmidi)

For :portmidi, add the following line:

(setf *default-midi-api* :portmidi)

If the above line is omitted, the MIDI API defaults to :jackmidi.
