ever having to touch the controls on TPX2s/4s. For this reason we will refer to such control as
Remote (not to be confused with wireless control).

Patch Changes

TPX2s/4s/6 responds to remote messages received on any channel. One simple message
recognized is Patch Change, which is Status byte 192-208 for channels 1-16. The Status byte
should be followed by one Data byte. The MIDI message format for this message is shown below.
Patch Change on Channel (192 - 208 = 1 - 16), Patch (0-127)

Bank Select

TPX2s/4s/6 responds to several MIDI Continuous Controller (CC) messages. Controller messages are
MIDI Status bytes 176-190 for channels 1-16. The Status byte should be followed by a Controller ID
byte and then a Data byte. Bank Select MSB and LSB messages are both recognized.
Controller on Channel (176 - 190 = 1 - 16), Bank Select MSB, LSB (0, 32), Bank (0-127)
TPX2s/4s/6 must be configured to send Bank Select messages in the format recognized by your
synthesizer, and this format is used by TPX2s/4s/6 for both sending and receiving Bank Select
messages. For more information, see the Appendix: Bank Select DIP Switch.

Tuning Table Changes

Other controller messages allow remote selection of TPX2s/4s/6 tuning tables. Three messages are
available which differ in the way that held notes are handled. These are Undefined Controllers,
numbers 116-118 (formerly 80-82). A Controller Status byte is followed by an ID byte and Data byte.
Controller on Channel (176 - 190 = 1 - 16), Controller ID (116-118), Tuning Table (0-127)
If notes are sustaining in one tuning and you want them to remain sounding in that tuning even after
the tuning table has been changed, use Controller ID number 116. If instead you want held notes to
change immediately to a new tuning, you have two options. The first is Controller ID number 117 in
which notes currently sounding are restruck with pitches in the new tuning. Controller ID number 118
shifts (bends) currently held notes to new pitches without restriking, but the changes in pitch for each
note are limited within the range of a 12ET halfstep.
