Advanced Applications
External MIDI Processors
Zone multiplication, for example, means that a full range of notes can be received on
one MIDI channel then the device divides them into zones and retransmits them on a
different MIDI channel for each zone. Typically a set of programmable parametersÑ
like low/high key, transposition, and velocity curveÑis available for each of the new
zones.
Arpeggiation creates a series of musically related notes in response to or inßuenced by
each note it receives. Rules for generating the series are usually highly programmable.
Receive Program Change
Setup storage for an entire MIDI system is one typical function of a MIDI processor.
Besides conÞguring its own operating parameters, a setup change can conÞgure
connected equipment as well. This is accomplished by the MIDI processor sending
MIDI Program Change messages to each device connected to it. In response, each
device selects a predetermined setup from its own memory. Sequencers can do this as
well when they replay recorded program changes.
For the Stage Piano to take advantage of such remote setup changes, it should be set to
respond to program changes as follows:
¥ Set the Set Chg Chan global parameter to the MIDI channel the processor will be
sending Program Changes on
¥ Make sure the Stage Piano is in MIDI Setups, Play mode
Example: The Kurzweil ExpressionMate
One MIDI processor/controller that works well with the Stage Piano is the Kurzweil
ExpressionMate. Figure 2-8 on page 2-10 shows how it can be connected in a system
with a Stage Piano, a sound module, and a computer. The wiring pattern is similar if
the sound module and/or computer is omitted; just continue the cable through the
missing device. The important feature is that the Stage PianoÕs output Þrst passes
through the ExpressionMate where it can be zone multiplied, remapped, arpeggiated,
etc. then through the computer, additional sound modules, and Þnally back into the
Stage Piano. You will want to turn the Stage PianoÕs Local parameter Off in this
conÞguration.
