is assigned to a channel list, only the lowest num-
bered channel in the lowest numbered slot will

sume the following channel list is dened:
SELECT CHANNELS 2!1, 2!2, 1!5
When CLOSE is pressed, Channel 1!5 will close.
2. When the single channel mode is enabled, all
stored channel patterns are cleared. For example, if
closed Channels 1!1 and 1!2 are stored at memory
location #001 (M1), enabling single channel will
clear that memory location.
3. The single channel mode cannot be enabled if two
or more channels are currently closed.
