Thank you for purchasing the MIDI Solutions R8 8-output MIDI-controlled Relay Array.
The MIDI Solutions R8 contains eight MIDI-controlled relays that enable switches or footswitch inputs to be placed
under MIDI control. Each 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. The MIDI Solutions R8 is MIDI-powered and requires no batteries or power
supply to operate.
INTRODUCTION
To program the R8 connect the MIDI Out from your MIDI interface to the MIDI of the R8. The MIDI and
can be left disconnected during programming.
Once the R8 has been programmed it can be inserted wherever it is required in your MIDI setup. Connect the MIDI
Out or Thru of the sending device to the MIDI of the R8. The can be made directly to
footswitch inputs or the contacts to be switched. The MIDI of the R8 can be connected to the MIDI In of a
receiving MIDI device or left disconnected. It is recommended that the number of MIDI Solutions products powered
by a single MIDI Out or Thru be limited to four.

The R8 is programmed by sending it MIDI System Exclusive programming commands from a computer with a MIDI
interface. These commands are described on the MIDI Solutions website, however
Upon receipt of a programming command, the R8's MIDI indicator LED flashes rapidly for about one second to
indicate that the setting has been stored. Ensure that the LED completes its flashing after receiving a programming
command before sending another programming command (the Programming Tools software automatically inserts
these delays). Settings are retained after power is removed, and the unit can then be inserted wherever it is required
in your MIDI setup.
The R8's MIDI Indicator LED will light as soon as the sending device is turned on, and flashes whenever MIDI data
passes through the unit. The R8 will respond to incoming MIDI messages according to its programmed settings. All
MIDI messages appearing at the MIDI In are passed to the MIDI Out.
the Programming Tools
software creates these commands automatically (see www.midisolutions.com/support.htm).
CLEAR SETTINGS
DUMP SETTINGS
LINK SETTINGS
To clear all of the R8's settings, send it the following System Exclusive programming command:
It is recommended to send the Clear Settings command to the R8 prior to programming the unit to ensure that all
previous settings are cleared.
To dump all of the R8's current settings, send it the following System Exclusive message:
Upon receipt of this command the R8 will dump its current settings to the MIDI Out.
To link together the Note and Control Change settings of a specific relay, send the R8 the following programming
command:
is set as follows:
= 00: Link OFF - each Note and Control Change setting operates independently
= 01: CLOSED Link - relay closes only if conditions of all Note and Control Change settings are in the
closed state
= 02: OPEN Link - relay opens only if conditions of all Note and Control Change settings are in the open
state
The link setting also has an effect on the power-up state of each relay. When link is OFF for a specific relay, that relay
will power up in the state in which it was previously powered down (powering up has no effect on the relay). When a
relay is set to CLOSED link, that relay will power up in the open state in order to prevent the relay from closing until
all messages to close it are received. When a relay is set to OPEN link, that relay will power up in the closed state in
order to prevent the relay from opening until all messages to open it are received.

PROGRAMMING COMMANDS

NOTE
To program the R8 to respond to a Note message, send it the following System Exclusive programming command:
( is optional)
All bytes must be in Hexadecimal format (see hexadecimal conversion table at end)
= Relay (00 for Relay1 ... 07 for Relay8)
is set as follows:
if is omitted then:
= 00: relay OPENS for Note-Ons and Note-Offs
= 01: relay CLOSES for Note-Ons and Note-Offs
= 02: relay CLOSES for Note-Ons, OPENS for Note-Offs
= 03: relay OPENS for Note-Ons, CLOSES for Note-Offs
if is included then:
= 00: relay produces CLOSED pulse for Note-Ons
= 01: relay produces CLOSED pulse for Note-Offs
= 02: relay produces OPEN pulse for Note-Ons
= 03: relay produces OPEN pulse for Note-Offs
= MIDI Note number
= MIDI channel (see MIDI channel table at end)
= Pulse width in 8 ms increments, or 1 s increments if preceded by 00
The R8 will accept a combined total of 10 Note or Control Change settings per relay.
To program the R8 to close Relay6 for 10 seconds when Note-On middle C is received on any MIDI channel, set
(Relay6), (relay produces CLOSED pulse for Note-Ons), (middle C is Note number 60, 3C is the
hexadecimal value for 60), (7F specifies all MIDI channels), and (0A is the hexadecimal value for
10, preceded by 00 to specify 1s increments). These values result in the following System Exclusive programming
command:
F0 00 00 50 26 01 F7
F0 00 00 50 26 01 rr aa nn cc (pp) F7 pp

CONTROL CHANGE
To program the R8 to respond to a Control Change message, send it the following System Exclusive programming
command:

is set as follows:
if is omitted then:
= 00: relay OPENS for control values
= 01: relay CLOSES for control values
= 02: relay CLOSES threshold, OPENS threshold
= 03: relay OPENS threshold, CLOSES threshold
if is included then:
= 00: relay produces CLOSED pulse threshold
= 01: relay produces CLOSED pulse threshold
= 02: relay produces OPEN pulse threshold
= 03: relay produces OPEN pulse threshold
= MIDI Control Change number
= MIDI channel (see MIDI channel table at end)
= Threshold value (threshold defaults to 64 if this byte omitted)
= Pulse width in 8 ms increments, or 1 s increments if preceded by 00
The R8 will accept a combined total of 10 Note or Control Change settings per relay.
To program the R8 to close Relay2 when the volume on MIDI channel 16 drops below a value of 10, and open when
it rises above, set (Relay2), (relay OPEN threshold, CLOSED threshold), (07 is
the Control Change number for Volume), (0F specifies MIDI channel 16), and (0A is the hexadecimal
value for 10, the desired threshold). These values result in the following System Exclusive programming command:
