D-10, D-20: Adjusting Panning and Level for each Part
If you are using an external sequencer, the easiest way to adjust panning and volume is to use the MIDI controller messages that are assigned to those parameters. Controller #10 is Pan and Controller #7 is Volume.
If you are altering these parameters internally, use the following procedure:
1) Press the MULTI TIMBRAL button.
2) Press the TUNE/FUNCTION button.
3) Use the DISPLAY buttons to call up the relevant parameters, Pan and Level, for each part.
4) Use the LEFT and RIGHT CURSOR buttons to select the parameter and the VALUE buttons to adjust the value.
5) Press the EXIT button.
