Doepfer A-127

A-127 VC Resonance Filter

The A-127 is a versatile module for sound modification.

Here are some application samples:

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)
