In most Banks, it's easy to audition different Patches stored in a Bank. Just click on a Patch and the program will send it to the instrument. Double clicking on a Patch will play the chord defined in the Tones Window. There's no need to go to the synth to audition Patches. If you have problems auditioning, make sure the Midi Channel, Comm Channel, and Midi Ports are set correctly by selecting the Settings button.
Banks are also capable of responding to remote patch changes.
If a patch change command arrives at a MIDI port that the program is monitoring, it will route this patch change to each bank window. If the bank is using the same MIDI channel as the patch change, the bank will automatically select the requested patch.
