One of the first and best-known MIDI patchbays, certainly in the US,
owing its success, at least in my opinion, to the fact that it makes
no attempt to be clever. It's primarily a 6-input, 8-output passive
patchbay (which means no interference or screw-ups), but there are two
virtual "processors" which provide simple MIDI processing
(channelising, delays, filtering, keyboard splits and so on); in
addition, the processors can be configured to provide 2-into-1
merging.
The great benefit of this unit is its stupidity; with the MIDI
processors offline there is no firmware to get things wrong, although
I never had any problems with it even using the processors. A couple
of minor drawbacks: firstly, it is rather opaque to programme, and it
takes considerable clarity of thought to quickly comprehend displays
like
IN 21M2A131 1>A
OUT 12345678 2>B
Secondly, the unit transmits All Notes Off to all outputs when it
receives a program change to select configuration (which must be sent
to a processor); it is therefore not always possible to keep a virtual
connection running while changing configuration.
This kind of device is all but obsolete these days, due to the
emergence of computer-based multiport interfaces, but given the
general flakiness of the latter, the MX-8 does have a certain appeal.
