TUTORIAL
Using MIDI
PROGRAM CHANGE
Press a SOUND SELECT button on the CA. You will hear the sound on
your external MIDI device also changes. Pressing a SOUND SELECT
button lets the CA piano transmit a “program change” number. A program
change is the type of MIDI command that tells the receiving instrument
what sound or instrument to play your notes with.
Actual program change information is just a number, from 1 to 128, not an
instrument name. You select the desired instrument with a specific number.
Not all MIDI instruments assign the same sound to the same program change
number. MIDI instruments that conform to the General MIDI (GM) standard
however “DO” assign the same sound to the same program change number.
For example program change #1 will always be an acoustic piano sound on
a “GM” compatible synth, and program change #33 will always be an acoustic
bass sound. Because of this, when connecting two “GM” instruments
together, selecting the right sound is not a problem. The CA piano is not a
General MIDI instrument and its internal sounds do not conform to the
General MIDI standard. This means when you select a sound on the CA
piano such as Classic E. Piano you will probably hear a different sound
playing from your external MIDI device. What sound you hear will depend
on the sound assignments on your external MIDI device. Below is a chart
of the Program Change number/sound assignment mapping for the first
twelve CA piano sounds and the first twelve “GM” sounds. Please see page
75 in the reference section for more detail. The CA piano can have different
mappings depending on the setting for multi-timbral mode (explained later
in this chapter).
