To remap the channels, enter a new channel number to the right of the
old channel number. Check the
"Enabled" checkbox to enable your settings. Channel mapping
applies to the current song in the current
Playlist.
You can redirect multiple channels into a single channel, but it has
adverse effects. Program, controller, and
effect information will all be combined together in the new channel. This
is probably not what you want to
do.
Also, if you map channel 10 (drums) to another channel, it will no longer
sound as drums, unless you
configure your synth appropriately. Likewise, other channels that are
mapped to channel 10 will sound as
drums.
