The Doepfer A-127-BOM Eurorack Breakout Module allows the separate use of each of the three A-127 filters. In addition the filters can be patched parallel or serial. Especially the serial connection of three notches generates very complex phasing-like structures. For parallel filter connection the existing mixer of the main module may be used or an external mixer. For serial connection the filters are patched in the desired sequence at the breakout module. A jumper is used to define the filter type for each sub-unit for the mix unit of the main module.
The main features of the Doepfer A-100PMS Monster Case Eurorack Synthesizer Case include:
Reproduction of resonances (fixed filter frequencies, resonances and amplitudes)
Triple internal or external CV controlled sweeps for very complex filterings
Filter effects similiar to vocoder and/or synthetic speech using specific external CV's to control the three filter frequencies (e.g. coming from the Sequenzer A-155 or MIDI-CV Interface A-191)
MIDI controlled filter settings or sweeps (e.g. in combination with A-191)
Random filter sweeps using random voltages (e.g. from A-118)
Triple S&H filter effects (in combination with S&H A-148)
Notch filter for each sub-unit
Separate outputs for lowpass, highpass, bandpass and notch for each sub-unit
Separate audio input with attenuator for each sub-unit
