10. Remote Control

10.1 Hardware Remote

The included Hardware Remote offers direct access to the most important functions needed in
a typical DAW workplace:
• Turning the VOL knob changes the volume (Global Output Level)
• Pushing the VOL knob activates DIM (Global Output Level -20 dB)
• Pushing the STORE button for 2 seconds stores the current level setting
• After changing the volume, RECALL sets the stored level value again
Note: The Hardware Remote uses the function Global Output Level, see chapter 9.2. The vol-
ume can not be changed if this option is deactivated in the Setup menu.

10.2 MIDI

The ADI-8 QS can be completely remote controlled via MIDI. It reacts on special SysEx com-
mands. Furthermore, upon request it will report the complete device status, including all con-
trols and LEDs on the front plate. Each ADI-8 QS can be programmed with its own ID, providing
a separated remote control of multiple devices via a single MIDI channel. A description of the
MIDI implementation is found in chapter 19.
The button REMOTE is used to select the source of the MIDI remote control commands: MIDI
port, MADI port and Off. The latter is a safety function to prevent any setup-change by any MIDI
signal.
With an installed I64 MADI Card the ADI-8 QS can also be remote controlled via MADI. Status
information of the unit is sent to all outputs simultaneously. With an installed I64 MADI Card this
includes embedded information at the MADI outputs (see 15.2, MIDI over MADI).
The diagram shows the signal flow of
the MIDI data with all I/Os. The MIDI
input signal reaches both the internal
Remote Command Processor and the
MIDI outputs. This MIDI Through func-
tion provides the base for a simplified
serial MIDI cabling when using multi-
ple ADI-8 QS. The same is true for
remote control via MADI, where MIDI
is passed through from device to de-
vice automatically via the serial MADI
cabling.

10.3 MIDI over MADI

MADI allows for a transmission of 64 audio channels over long distances with a single line –
perfect. So what about MIDI? Be it remote control commands or sequencer data, in practice
only a single MADI line will not suffice. Therefore RME developed a MIDI over MADI technol-
ogy. The data at the MIDI input are being included into the MADI signal invisibly, and can be
collected at the MIDI output of another ADI-8 QS, ADI-6432, ADI-642, ADI-648, Micstasy or a
HDSP MADI, at the other end of the MADI line.
Technically every single MADI channel includes several additional bits, containing various in-
formation (Channel Status). RME uses the usually unused User bit of channel 56 (channel 28 in
96k frame mode) to transmit MIDI data invisibly within MADI, ensuring full compatibility.
