Integrating the VCLFO into a MIDI system
Unlike the A-145 and A-146 LFOs, the A-147’s fre-
quency can be voltage controlled.
This above all gives you the chance to use a MIDI-CV
interface (such as the A-190 or A-191) and use your
chosen controller to
adjust the VCLFO frequency via
MIDI.
That makes the LFO frequency in effect program-
mable, and also naturally means that you can control it
while playing in real time.
