The Arpeggiator
Arpeggiator parameters

Key range (Low Key, High Key)

The low and high key determine the note range the Arpeggiator
will see. You can set it so that one area of the keyboard will
arpeggiate notes while the other will play normally. You can split
the keyboard so each area arpeggiates one zone.
One thing to understand is that transposing the notes within a
zone will affect how the key range parameters in the Arpeggiator
function. Here is an example:
Start with Factory Setup 1, ABS Bend. Press the Arpeggiator
button and scroll to the Key Range parameters, setting Low Key
to C4 and High Key to C5. Now turn the SW2 button On. Play
your keyboard and you will notice that the keys between C4 and
C5 arpeggiate, while any other keys just play a single note.
Now press The Controllers buttons until the Zone 2 LED is lit.
Scroll to parameter 1, MIDI Channel and set it to Mn2. Make sure
that channel 2 on your sound source has a valid program
assigned. Now when you play the keyboard between C4 and C5,
you hear the zone 1 arpeggiating while zone 2 plays single notes.
Next press the Controllers button until Zone 1 is highlighted and
scroll to parameter 126 Nt Xpos. Set it to -7. Now if you play the
keyboard, you will see that Zone 1 arpeggiates From G4 to G5
AND the pitch has been transferred down so that Zone 1 plays a
5th down in pitch from Zone 2.
Finally, press the Arpeggiator button and scroll to parameter 16
Transpose and set it to 7. Note the pitches of Zone 1 have been
transposed back so that they are the same as Zone 2, but the
arpeggiation still happens between G4 and G5.

Enable Switch (Enable Sw)

Turns on the Arpeggiator. It can also be turned on by Ctlr48.

Note Source (Note Src)

This determines where the Arpeggiator gets its note input from.
Each Zone can see notes from any of the three Controller Zones
note output, CC Notes or from another Arpeggiator Zone
(Cascading Zones). The ExpressionMate cannot send notes from
an arpeggiator Zone to itself nor can it see notes sent from the
