Wersi EX20 MIDI Expander

   0 reviews  -  2836 views

    After 10 years as an organ manufacturer, Wersi enters the synthesizer field with the EX20 module. A digital 20 note polyphonic synthesizer.

    Its sounds are based on a configuration of sounds modules such as wave, pitch-envelope, amplitude envelopes and analog effects to produce fourier, waveform sample, and modular synthesis. The front panel features a 32 slider 'wavemaker' module used for each synthesis mode.

    A 61 note velocity & pressure keyboard can split and provide up to 8 timbres simultaneously per side. The EX20 is a rack mount version of the Wersi MK1. Both instruments can 'see' up to 16 midi channels for multitimbral operation, and transmits on up to 8 channels at one time."
