Changing Setups: Special Considerations
setup are sent at setup change time. When the effect
type
(number) changes, the Stage
Piano will brießy mute the effects processor to avoid any audible pops and clicks.
Although much less objectionable than a click, this momentary muting will be audible
if notes are sounding or still decaying during the changeover. However, if the effect
number is the same in the old and new setup or the new setup speciÞes
Noc
(no
change), then no muting occurs.
Another consideration when changing setups is
paired messages
. A note, for example is
started by a Note On MIDI message when the key Þrst goes down and is stopped by a
Note Off message when the key returns to rest. If there is a setup change between the
two that causes notes in that part of the keyboard to be sent on a different MIDI
channel or with a different transposition, then the Note Off will not be ÒheardÓ by the
sound module and a stuck note results.
Paired messages are also produced by switch pedals, notably Sustain and Sostenuto.
When the pedal is pressed down, an On message is sent; when it is released, an Off
message is sent. If the MIDI channel changes between the two, then the previous
channel, and thus any notes being held by it, will never receive the Off message and
the notes will be stuck.
When stuck notes occur you can always clear them with the
Panic
double-press but
itÕs better to avoid the situation. One way is to ensure that both the current setup and
the next setup have compatible MIDI channel assignments and transposition. Or, if
they must be incompatible, you can make sure that all keys are up before the change. If
the MIDI channels are incompatible, the switch pedals will probably need to be up as
well.
