Note On, Note Off
Note On messages control the start of each note you hear from the V150/V110. The message
contains information stating which MIDI channel the note is on, what note it is, and how hard
the key was struck (the attack velocity). When the V150/V110's sound-producing components
receive this message (either from the V150/V110's keyboard or from an external MIDI source),
the information gets translated into the note you hear. When you release a key, a similar Note
Off message is sent saying that a note has ended, on which channel, what note, and how fast the
key was released (the release velocity).
Aftertouch
Aftertouch is a Controller message that affects sounds that are already playing. Many V150/
V110 sounds respond to aftertouch in various ways (by changing timbre, for example).
To use aftertouch, play a note, then hold the key down and press on it. The V150/V110 uses
channel aftertouch, which means that pressing on just one key affects all the notes that are
playing on that MIDI channel.
Pitch Bender
Touching the Pitch Bend pad sends MIDI Pitch Bend messages that change the pitch of all the
notes that are currently playing.
Program Change Messages
Whenever you select a sound, the V150/V110 sends a MIDI Program Change message. This
message is always preceded by a Bank Select message (described below). The V150/V110 also
can receive Program Change messages from external MIDI instruments. To change a sound on
the V150/V110 this way, you should send a Bank Select message, followed by a Program
Change message.
Control Change Messages
Control Change messages make up the largest category of MIDI messages. The V150/V110 can
send many different Control Change messages, making it easy for you to modify sounds—
whether you're playing live or playing a prerecorded song (sequence).
Bank Select
By definition, MIDI offers exactly 128 values for the Program Change message. Since the V150/
V110 contains several hundred sounds, there aren't enough Program Change values for you to
select all the sounds directly with MIDI Program Change messages. Consequently, there's a
Bank Select message, which enables you to select several banks of 128 sounds (by sending a
Bank Select message followed by a Program Change message). The V150/V110 responds to
MIDI Controller 0 and Controller 32 messages as Bank Select messages (except when in General
MIDI mode).
To change banks, send MIDI Controller 32 message with a value corresponding to the bank you
want to select. See Appendix C to find the right combination of Bank Select and Program
Change messages to select the V150/V110's sounds. These correspond to the bank number and
sound ID of the sounds in the various tables.
