In the A panel set, each sequencer channel has a strip of output pins at its lowest left. These are copies of the full MIDI output matrix pins for the currently displayed sequencer channel. Changes to a sequencer channel in the A panelset appear immediately in the big output matrix in the B panelset, and vice versa.
To toggle MIDI outputs on and off, click on the cells. Rings are disabled, and solid boxes are enabled.
The rings around each pin flash when either the current sequencer channel, or another sequencer, sends a note to that MIDI channel.
For more information on the output matrix, see the full description for the MIDI output matrix in the B panelset.
The output panel was added to the A panelset in v099.
