3.4 Integrating the A-100 with MIDI
To link the A-100 into a MIDI system, you can use
external MIDI interfaces like our MCV4, MSY2 or
MCV24.
The MIDI-CV/SYNC Interface A-190-1 is a MIDI-to-
CV/Gate/Sync interface with the following outputs:
• CV 1 (for pitch control, 12 Bit)
• CV 2 (any MIDI-Controller, 8 Bit)
• Gate
• Clock
• Start / Stop
The A-190 automatically sends pitch control CV and
gate information out on the INT.CV and INT.GATE
busses.
Another solution is the usage of the low cost MIDI-CV
Interface A-190-2 which has one Gate and four CV
outputs available.
Another suitable MIDI-CV Interface for A-100 was the
24-channel MCV24, a 19” rackmount with its own
power supply. As the MCV24 is no longer in production
you will have to try to find a second hand unit.
VC Modules like the A-141 VC-ADSR and A-147
VC-LFO can be controlled via the A-190-1 or A-190-2,
so that, for instance, a continuous MIDI controller can
alter envelope parameters in real time. Since these
controllers can be recorded by a MIDI sequencer, VC
modules are effectively programmable.
Analog sequencing can be provided by the A-155 or
the external MAQ 16/3 MIDI Analog Sequencer.
To convert up to 16 control voltages in the range
0...+5V (e.g. from a Theremin A-178 or Joy-Stick
A-174-1 or Foot-Controller A-177-2 or ribbon controller
A-198) into MIDI controllers the CV-to-MIDI interface
A-192 is the right choice.
