VCA
• manual amplitude control
• AM (amplitude modulation) control with modulation
source switch (LFO1 / off / ADSR)
• external CV input for VCA amplitude
• special control scale: exponential scale in the range from
about -20dB to -80/90dB, linear scale from about -20dB
to 0dB
Remark: this special control scale results in a loudness
behaviour that is a bit different from pure linear or
exponential VCAs
LFO1 and LFO2
• manual frequency control
• waveform switch (triangle / off / rectangle)
• range switch (low, audio, medium)
• LED display (dual green/red color for positive/negative
share of the signal)
• the inverted LFO1 signal is available as an additional
socket (to use the LFO1 signal for external modules)
• an internal jumper can be used to select between the
LFO1 signal or the inverted LFO1 signal
ADSR
• manual controls for Attack, Decay, Sustain, Release
• range switch (long, short, medium)
• blue LED display
• ADSR signal is available as an additional socket (to use
the ADSR signal for external modules)
• Gate input connected to the A-100 bus via jumper, the
jumper can be used to interrupt this internal connection if
not wanted
