What we think?

Another example of Wowa Cwejman's excellent design skills, the SM-1 takes the essence of the S1's unique flavour and tonality and offers those signature building blocks in a semi-modular, eurorack synth voice.

The Cwejman SM-1 is a luxury, premium quality semi-modular analogue synthesizer in Eurorack format, which boasts some of the core building blocks from Cwejman’s signature S1 synthesizer including their lovely multi-mode filter, super snappy EG’s and their unique oscillator circuits.


For several decades Wowa Cwejman has been developing some of the most revered and tonally unique synthesizer circuits, most notably is the S1 semi modular synthesizer. The SM-1 as its name gently suggests is a Eurorack modular take on the S1 architecture, with two multi-wave analogue oscillators, a glorious multi-mode filter, two loop-able ADSR’s and a precision VCA.


Some of Cwejman’s unique additions some of these tried and tested circuits have been implemented on the SM-1, to give it a wide variety of possible tones and increase the array of modulation capabilities, for example:


The multi mode filter can achieve:


  • 12db, 24db low pass
  • 12db, 24db high pass
  • 6db, 12db band pass
  • And three dual band-pass arrays
  • There’s also a spacing control to separate the resonant peaks of the filters, to create amazing formant tones and much more.

  • To say this is a stunning example of a subtractive synthesizer would be an understatement, Cwejman synths have a character all of their own and the SM-1 will bring new life into an existing modular system or give users a top end system to build a system on.


    The main features of the Cwejman SM-1 include:


  • Semi modular analogue synthesizer voice
  • Eurorack format module
  • 56HP wide
  • Stunning build and sound quality
