ADDAC System - 107 Acid Source

Product information "ADDAC System - 107 Acid Source"
We started this module with the idea of developing a complex drum source. However, somewhere along the process we noticed how much better it performed as a synth voice and simply embraced this lucky accident.

It features a VCO with a [FREQUENCY] and [FINE TUNE] knob plus a dedicated CV Input and Attenuator knob (tunable over 4 octaves). The VCO waveform output is achieved by selecting either a Triangle or Saw through a switch. The selected waveform can then be mixed/balanced against the square wave. The resulting mix is then sent to the Filter.

The Filter features a [CUTOFF] and [RESO] resonance knob plus a Cutoff CV Input and Attenuverter knob.

A 3 position switch is used to select the filter type: Highpass, Bandpass or Lowpass. The resulting output is then sent to the VCA.

The VCA features an Input with [INPUT GAIN] knob which at maximum can amplify the incoming signal by a factor of 2.

This is a very important control, it accepts any signal Trigger, Gate or CV. Whatever input is plugged in the signal is then fed through an AD with a very short attack and controllable decay through the [VCA DECAY] knob plus the CV Input and Attenuverter knob. The resulting slewed signal is then used to control the VCA gain. This signal is also sent to the CV OUTPUT as well as the LED monitor.

The Accent input adds to the Input signal creating a different amplitude output. The CV OUTPUT is normalled to the Frequency and Cutoff inputs.
