The quantity of sequences in the bank may be adjusted using the Grid size menu option. This allows selection of 1, 4, 9, 16, 25, 36, 49 or 64 sequences but does not change the MIDI channel of any tracks or group of any sequences. This may be undesirable if you use ZynPad as a column based performance tool in which case it may be more appropriate to change grid size from ZynPad menu.
