The A-116 module provides voltage-controlled, dynamic waveform modification of audio signals. It can produce new waveforms from the standard, basic forms; with such changes also having the option of being modulated.

The signal first of all goes through an input amplifier with a gain range from 0 up to 2, i.e. the signal can be both attenuated and amplified up to a factor of 2. After the input amplifier, the signal goes through two parallel processors.

Signal processing paths: clipping and an asymmetrical amplifier. Subsequently, the modified signals are then added and fed to the output. The parameters of the clipping level and symmetry can be set manually as well as modulated by control voltages, which allows for very complex and dynamic waveform changes.

The A-136 is a distortion and wavehaping module with extensive adjustment parameters. The input signal (audio- or control voltage), is first divided inside the module into 3 separate signal paths, which are mixed together at the output with adjustable gain (positive / negative):

By way of all the various possible settings of the 5 parameters, very complex waveform distortions and modifications (waveshaping) are possible. The changes range from simple hard- or soft-clipping, to completely changed waveforms, in which the original input signal can no longer be recognised.

• Positive component of the signal with adjustable clipping threshold (also externally); and gain / roll-off (+/-)
• Negative component of the signal with adjustable clipping threshold (also externally); and gain / roll-off (+/-)
• Original signal with adjustable gain / roll-off (+/-)
• Inputs: Audio / CV In, ext. Clipping Level (+), ext. Clipping Level (-)
• Outputs: Audio / CV Out
• Application examples: Audio distortion (can get especially interesting in conjunction with filters), waveform manipulation for audio- and control signals (LFO, ADSR, random, etc.).
