Doepfer A-100 Basic System 1 G6 with PSU3

The A-100 Basic System 1 is a preconfigured modular system that offers all the components of a flexible monophonic synthesizer. It is a good entry into the modular world and, thanks to its clarity, helps to understand the interaction of the individual modules. The user can expand the system with additional frames or replace individual modules as required. Basis System 1 has no MIDI interface, but can only be controlled via CV/Gate e.g. from an analog sequencer like the MAQ-16/3.

Following modules are included:

  • 2x Standard VCO A-110
  • 2x ADSR A-140
