Manual

These menus are available:
MODE
This menu is used to select the assign mode, i.e. the rule which key is used to
generate the control voltage CV1 if two or more keys are operated at the same time.
Older monophonic synthesizers had normally one fixed assign mode. In the A-
100CGK one can select between these three assign modes:
Display Function Explanation
HIP Hight Note Polarity The highest currently pressed key is used to
generate CV1.
LOP Lowt Note Polarity The lowest currently pressed key is used to
generate CV1.
LSt Last Note Polarity The last of the currently pressed key is used to
generate CV1.
TRANSP.
This menu is used to transpose the keyboard. According to the transpose type
selected in the configuration mode (octave or semitone, see below) the transposition
is made in octave or semitone intervals. The display shows the transposition in
semitones:
•
octave type transposition: 0 or 12 (+ one octave)
•
semitone type transposition: 0, 1, 2, 3 to 12 (+ 1, 2, 3, …12 semitones)
Remark: For the OEM versions of the A-100CGK the transposition ranges are
different according to the keyboard type:
•
2 octaves keyboard: 0 to 36
•
3 octaves keyboard: 0 to 24
•
4 octaves keyboard: 0 to 12 (same as described above)
•
5 octaves keyboard: no transposition possible
The reason for the different transpose ranges is the voltage range of CV1 (0...+5V).
This corresponds to 5 octaves overall range.
RETRIG.
This menu is used to adjust the behaviour of the gate output in legato play (i.e. when
a second key is operated while the first one is held down). The value shown in the
display is the reset time of the gate output in milliseconds when another key is
operated. If this parameter is set to zero no reset appears, i.e. an ADSR type
envelope generator triggered by the gate signal remains in the sustain state. If the
parameter is set to a value 1 … 20 the gate output is reset for a short time (the value
shown in the display in milliseconds) when another key is pressed. In this case the
envelope generator is triggered again. For all envelope generators of the A-100 the
value 1 (i.e. 1 millisecond) is sufficient for retrigger. If other envelope generators are
connected one has to find out the minimum reset time for retrigger by trial and error.
HOLD
When this button is operated the gate output is set to high no matter if a key is
pressed or not. The hold function is displayed by the four menu LEDs. These light up
whenever the hold function is active. If the hold button is operated again the hold
function is cancelled.
