Drum-99

Stereo Drum Mixer

The DRUM-99 module is an audio-mixer that has been designed for the modules of the MFB-DRUM series but also for usage with other manufacturer's modules. When using multiple drum-modules in a modular system, the following processing stages like filters or VCAs often lack enough audio inputs. To route a complete drum-set through a filter, a separate mixer like the DRUM-99 comes handy.
