  • Clock Man, a master clock module. It creates DIN-Sync and/or MIDI-Clock, and also is able to control the settings of connected Clock Boy modules with a dial and display

  • Clock Boy, a clock slave module, which translates DIN-Sync or MIDI-clock into an "analogue" clock signal and corresponding control triggers. Clock Boy provides six clock divisions, a pause/start-in function, swing/shuffle, and provides various reset modes.

  • VMC, a set of voltage controlled MIDI orientated modules for Eurorack
  • cv2midi, an Arduino software for the eurorack module VMC-2. It translates incoming voltages and triggers/gates into various MIDI data. (Trigger to MIDI, CV to MIDI).
  • SQ-3P, an Arduino software for the eurorack module VMC-1. It provides a simple polyphonic MIDI step sequencer inspired by the sequencers in the Roland JX-3P and SH-101
  • SQ-4M, an Arduino software for the VMC-system. It provides a monophonic multi track MIDI step sequencer inspired by the sequencers in the Roland JX-3P and SH-101
  • chordtrigger, an Arduino software for the eurorack module VMC-1. It provides a chord trigger function. Played chords are repeated either by a clock signal or according to a programmable pattern. The velocity is controlled either by a separate pattern, controlvoltages, or note individual random values
  • MC-1, an Arduino software for the eurorack module VMC-1. It provides a simple MIDI clock generator.
  • torroid transformers for 115/230V suitable for Roland JX-3P, Juno-Series, TR-909, Microwave A/B, Yamaha DX-7, generic eurorack supplies
  • DIN-Sync to analogue clock interface (This has been replaced by the Clock Boy; see top of the page)

Services - repair and modification of synths and analog studio gear
  • Service Manuals: This is a link to Rob Senso's website. He offers a huge collection of exceptional scans of service manuals for all kinds of electronical musical devices. You can download them without restriction, but I ask you to be fair and donate a little money as he asks you on top of his page. If you did so already, the you may scroll down on his page.
    I removed all service manuals from my page with exception of those, which are not available at synfo or which I scanned in better resolution.
