INTRODUCTION Thank you for purchasing the MIDI Solutions Relay. The MIDI Solutions Relay contains a MIDI-controlled relay switch that enables a switch or footswitch input to be placed under MIDI control. The Relay can be programmed to respond to a wide variety of MIDI messages, including Note, Control Change, Program Change, and System Exclusive messages, and programmed settings are retained even after power is removed from the unit.
PROGRAMMING COMMANDS CLEAR SETTINGS To clear all of the Relay's settings, send it the following System Exclusive programming command: F0 00 00 50 06 00 F7 It is recommended to send the Clear Settings command to the Relay prior to programming the unit to ensure that all previous settings are cleared.
NOTE To program the Relay to respond to a Note message, send it the following System Exclusive programming command: F0 00 00 50 06 01 aa nn cc (pp) F7 (pp is optional) All bytes must be in Hexadecimal format (see hexadecimal conversion table at end) aa is set as follows: if pp is omitted then: aa = 00: relay OPENS for Note-Ons and Note-Offs aa = 01: relay CLOSES for Note-Ons and Note-Offs aa = 02: relay CLOSES for Note-Ons, OPENS for Note-Offs aa = 03: relay OPENS for Note-Ons, CLOSES for Note-Offs if pp
CONTROL CHANGE To program the Relay to respond to a Control Change message, send it the following System Exclusive programming command: F0 00 00 50 06 02 aa nn cc (tt pp) F7 (tt and pp are optional) All bytes must be in Hexadecimal format (see hexadecimal conversion table at end) aa is set as follows: if pp is omitted then: aa = 00: relay OPENS for all control values aa = 01: relay CLOSES for all control values aa = 02: relay CLOSES above threshold, OPENS below threshold aa = 03: relay OPENS above thresho
PROGRAM CHANGE To program the Relay to respond to Program Change messages, send it the following System Exclusive programming command: F0 00 00 50 06 03 (aa pp) cc nn nn ... nn F7 (aa pp) is optional All bytes must be in Hexadecimal format (see hexadecimal conversion table at end) if aa pp is omitted then relay CLOSES for all programs nn and OPENS for all other program numbers.
SYSTEM EXCLUSIVE To program the Relay to CLOSE upon receiving a System Exclusive message, send it the following programming commands: F0 00 00 50 06 04 01 (pp) F7 followed by F0 ... F7 (pp is optional) where F0 ... F7 is the System Exclusive message the relay is being programmed to respond to (max. 20 byes) All bytes must be in Hexadecimal format (see hexadecimal conversion table at end) pp = Pulse width (CLOSED pulse) in 8 ms increments, or 1 s increments if preceded by 00.
MIDI CHANNEL TABLE The value cc in the programming commands is assigned according to the following table: MIDI Channel 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ALL cc 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 7F MIDI CONTROL CHANGE TABLE Decimal 0 1 2 3 4 5 6 7 8 9 10 11 12-13 14-15 16-19 20-31 32-63 64 65 66 67 68 69 70 71 72 73 74 75-79 80-83 84 85-90 91 92 93 94 95 96,97 98,99 100,101 102-119 120-127 Hexadecimal 00 01 02 03 04 05 06 07 08 09 0A 0B 0C-0D 0E-0F 10-
