The MIDI Solutions R8 offers 8 MIDI-controlled contact closures, each of which can be programmed to respond to a unique MIDI message.
The MIDI Solutions R8 8-output MIDI-Controlled Relay Array contains eight relays which can be programmed to open or close in response to MIDI events.
Event types are programmable and include: - Note - Control Change are used for a response time of less than 2ms. Relay contacts are rated at 500mA. Contacts are made available via connections to the tip and sleeve of 1/4" mono phone jacks.
The R8 is programmed by sending it MIDI System Exclusive messages (see FAQs - Programming). This can be done easily with the Programming Tools software for the F8 and R8. Once programmed, the R8's settings are retained even after power is removed. The R8 can be reprogrammed with new settings as often as needed.
The R8 is MIDI-powered, and requires no batteries or power supply to operate with most products (see FAQs - Power for more information). A MIDI indicator LED lights up when the product is powered and flashes when MIDI data passes through it.
