REF. OFFSET
This parameter sets the voltage offset for the bottom
note - and works in the same way as the VCO’s Tune
control. In normal use, this is set to 0 V.
m m m m Increase or decrease the amount of voltage
offset.
H The INC- and DEC- buttons speed up
if you keep holding them down.
SCALE
This parameter sets the fine scaling of the pitch-
control DAC so that MIDI and A-100 VCO notes are
completely in tune over their whole range (see dia-
gram on page 12).
After setting the bottom note and voltage offset, you
send a MIDI note to the A-190 - usually the note ex-
actly an octave or several octaves above the bottom
note. Using the SCALE parameter, adjust the voltage
sent to the VCO to ensure that the octaves are com-
pletely in tune.
H For use just with the A-100, it may well be
fine to leave this at the standard factory
setting of exactly 1.00 V / octave.
m m m m
Increase or decrease the amount of voltage
offest on the higher note.
H The INC- and DEC- buttons speed up
if you keep holding them down.
In the example on page 12, after the V / octave
response, bottom note (MIDI note 36) and voltage
offset (0 V) have been set, the SCALE parameter is
adjusted so that when MIDI note 84 (exactly four
octaves above the bottom note) is received, the VCO
note played is precisely four octaves higher. (That is,
the pitch CV is exactly four volts.)
