By default sequences are arranged in columns of groups with the first column being in group A, second column in group B, etc. and the last column being in group J. (This is because the default configuration also allocates MIDI channels 1, 2, etc. and 10 for last column which is traditionally used for percussion.) ZynPad tries to keep things simple with each sequence containing a single track and a single pattern. We will see later how this can be changed with Arranger. Following this simple workflow, a sequence's MIDI channel may be set from the menu option MIDI channel. This also sets the sequence's group. There are 16 colours used to indicate groups so that each MIDI channel may have a different colour.
