SynthesizerExpanderModule

 

The SEM was my first synthesizer, well-loved for its beautiful sound and just the right combination of synthesis modules plus patching in a compact, portable package. Over the years, lots people have asked me if I could make it again, so I did!

The SEM is available in three versions:

SEM PRO  US$1199

 

SEM with MIDI to CV Converter and integrated Patchpanel. This version combines the features of the MIDI to CV version (see below) with a 21-jack patchpanel and is personally autographed by me.

 

  • Select MIDI channel, controller number and bend range
  • Select note assignment modes: latest, high note and low note priorities
  • Select note re-trigger, filter track, LFO reset
  • A second independent control bus allows velocity, controller data, or channel pressure to modulate either or both VCOs, the filter and the VCA
  • Transpose function allows different keyboard controllers to utilize the complete MIDI note range
  • Analog portamento
  • Input preamp gain control - allows an external audio input to be processed thru the SEM
  • High precision A-440 Hz tune signal
  • Control voltages and gate are bought out to rear panel connectors so MIDI to CV function can be used with other CV/Gate gear.
