ADM17 Proton - 12HP

Audio Damage ADM17 Proton

More than just a capable vintage digital style delay, the Audio Damage Proton implements 1V/Oct tracking and an enveloped noise burst that produces a sound similar to that of a plucked string. 

The Proton’s delay line is tunable via front panel coarse and fine tune knobs. From there, the signal is routed through a low-pass filter modeled after that on the Korg MS-20, albeit with additional dampening circuits. From there, a random noise burst batters the reverb in order to produce a characteristically plucked sound. There’s also a choke input that vacates the delay line, affording an extra option for sonic governance.

ADM17 Features

  • Proton is a DSP-based module that runs at 48kHz sample rate and 24 bit depth, via a high quality Cirrus-Logic codec. 
  • The PITCH control sets the delay time, while the FINE TUNE knob provides further control. The PITCH input responds to 1V/Oct. 
  • The DAMPING control is the corner frequency of an MS20-style low pass filter in the feedback path of the delay. 
  • The DECAY control is an additional feedback amount control, not normally found in KS synthesis. This enables bright tones with short decays. 
  • The IMP FILTER controls a pair of filters on the noise burst impulse. At 12 o'clock there is no filtering. Anti-clockwise controls the corner frequency of a low pass filter, and clockwise the same for a high pass. This controls the timbre of the impulse, and the resulting pluck. 
  • The IMP DECAY control sets the release time of the noise burst's envelope. This results in a heavily colored pluck.
  • The SUB knob controls the level of a sine wave, the frequency of which is set by the PITCH and FINE TUNE controls. This allows a false low end, normally missing from low-pitched Karplus-Strong plucks. 
  • The MIX knob controls the wet/dry mix (if using the audio input) or the level (if using the internal impulse.) Both the internal impulse and the input can be used simultaneously. 
  • MANUAL and TRIGGER fire the internal impulse. CHOKE closes the DECAY value, and this is not reset until a new TRIGGER is received. 
  • Proton can be used as a normal delay with the input; the DAMPING, DECAY, and MIX control the level, while PITCH sets the delay time. 
  • Every control has a CV input that accepts +/-5V. Panel controls are sampled at low audio rates (approximately 35Hz), and have further internal lag processing for smooth parameter changes.
