Tags: jv-880
In the Rhythm Part, it is possible to edit parameters for the sounds that are
assigned to each MIDI note number. Panning and effects levels are two of the
possible edit parameters.

1) Press RHYTHM.
2) Use the CURSOR buttons to select the parameter setting.
3) Use the DATA dial to select the parameter to be edited.
4) Cursor to the Value and set it to the desired amount.

Use TVA level to adjust the volume (0-127).
Use TVA pan to adjust panning (L64-0-R63, Random).

Note: You can only edit the rhythm sounds in the User programmable memory 'I'
or 'C' banks.
