Chapter 7 Environment Configuration and
Playing back arpeggio on the MC-307
using an external MIDI keyboard
This setting enables the MC-307 to play back arpeggio upon
reception of note messages from a particular MIDI channel.
(If the Remote Keyboard Switch is "ON," you can simply
turn the arpeggiator on and play the external MIDI keyboard
to produce arpeggios.)
Procedure
If the MC-307's Remote Keyboard Switch is set "OFF,"
1. Set the MC-307's Arpeggio Control Channel to match the
transmit channel of the external MIDI keyboard (P. 124).
* It is a good idea to set the Arpeggio Control Channel so it does
not conflict with the transmit/receive channels of each of the
MC-307's parts.
2. Press [ARP] button to turn the arpeggiator on.
3. When you play the external MIDI keyboard, arpeggios
will sound on the selected part.
