In fig. 3, the CV input is fed from the sine output of a
LFO. The sampling frequency is 32kHz, the LFO fre-
quency 21 Hz. The resulting wavetable pages are
shown in the boxes.
fig. 3: wave record mode with modulated wavetable
page number
Waves recorded in this way may be played back in the
normal play mode, often leading to some fairly drastic
effects.
• Wave play mode
In this mode A-112 works as a wavetable oscillator.
The wavetable number (page) that determines the
sound of the audio output is set by the control voltage
applied to the audio/wave CV input !
Gate = low:
The module is waiting for gate = high; LED 3 is off.
The initial sampling frequency (i.e. the first frequency
when gate turns to high, see below) is set. Pre-
listening mode is also used to find out and set the
sampling frequency.
Gate = high:
When the gate goes high the wavetable number
(audio/wave input) and the sampling frequency (tune
control and CV input) are set, and playback of the
recorded wavetable begins, using the sampling fre-
quency previously set (LED 3 turns on). When the end
of the wavetable is reached the process starts again,
