MIDI Implementation

There is a preference setting in the 'Prefs' dialog that controls whether Augustus Loop responds to MIDI events on all channels, or just on channels 1&2.

In the latter case, the plug-in responds to MIDI controller messages on channel 1 (see table below) and to note on messages (to alter the pitch setting) on channel 2. This can make it more convenient to play a soft-synth and control Augustus Loop from the same keyboard.

Some parameters are controlled by NRPN messages rather than CC messages because they require the extra (14 bit) resolution. NB the 'Delay Slider' has both a CC and NRPN assigned to it.
