MODE (NOTE ASSIGNMENT)

Mod

The MODE parameter controls the note assignment. It
determines which note will be generated when more than
one key is held down at once.

Hig

(Highest note – default setting)


Lst

(Last note)


CV CHARACTERISTICS

CvC

This parameter sets the voltage control characteristics
of the pitch CV output (CV1) from the A-190-4, so that it is
possible to drive both common types of analog synth –
vintage Korgs, Yamahas, etc., which have a linear
response (Hz / V), and Rolands, ARPs, Moogs, etc. which
have a logarithmic response (1V / octave).

For use with the A-100, only the V / octave setting is
needed. The Hz / V option is provided for connecting
external (vintage) synths which use that standard.
Thus the default setting is Volt / Octave.

H-U

(Hertz / Volt)


U-O

(Volt / Octave – default setting)


SCALE

SCA

This parameter sets the fine scaling of the pitch-
control DAC (CV1)
so that MIDI and A-100 VCO notes
are exactly in tune over the whole note range.

After setting the REFERENCE NOTE (see above) and
TUNE (next following parameter), please send a MIDI
note to the A-190-4 – usually the note exactly one octave
or several octaves above the reference note. By using the
SCALE parameter, adjust the A-190-4’s output voltage in
order to provide perfectly tuned octave ranges.

This function is devided into a coarse and fine
adjustment. Both values range from 000 to 126.

The first hit on the ”

” button accesses the coarse

setting. A second hit accesses the fine setting.

Hitting ”

2 ” leaves the value entry menue.

For use with the A-100, please leave this value at the
standard factory setting of exactly 1.00V / octave.
