MIDI Show Control Protocol
The MIDI Show Control protocol is primarily used when controlling the
Binloop over its dedicated MIDI port. However, it is also available as one
of the configurable protocols available on the RS-232 Show Control port.
If your intention is to control the Binloop with a non-MIDI based system,
you should consider using the Pioneer/AMI protocol instead.
It should be noted that MIDI Show Control is a very wide-ranging
protocol used for many different applications. Most of the protocol
information is beyond the scope of this manual since it is not critical to
controlling the Binloop.
General Structure
MIDI Show Control uses a single Universal Real Time System Exclusive
ID number (sub-ID #1 = 02H) for all Show commands (transmissions
from Controller to Controlled Device). In this version of MIDI Show
Control, command responses (from Controlled Devices to Controller) are
specified in order to optimize bandwidth requirements, system response
time and system reliability in the event of communication difficulties with
one or more Controlled Devices. The guiding philosophy behind live
performance control is that, as much as possible, failures of individual
Controlled Devices should not impair communications with other
Controlled Devices. This concept has been a part of MIDI system design
from the beginning and MIDI Show Control continues to use an "open-
loop" design in order that standard MIDI practices may continue to be
successfully utilized in applications using all types of standard Channel
and system messages.
