Published on Apr 12, 2019 Synthtopia

"At SynthPlex 2019, CHRT Synthesizer was showing their unique vacuum tube analog synthesizer.

It's available as a DIY kit or pre-built.

We talked with Petr, who gave us a hands on demo and some background on why he chose to create a synth design using tubes."

MESSE 2018: CHRT Synthesizer - Analog Valve Instrument For Wind Instrumentalists | SYNTH ANATOMY

via http://www.chrtsynth.org

"CHRT Synthesizer is a true analog monophonic valve sythesizer, designed mainly as a sound module for MIDI wind controllers, such as Yamaha WX5 or Akai EWI. A slight variation of firmware can turn it into a greatly responsive sound module for a keyboard player.

The main features of CHRT Synthesizer are:

natural electric, real synth sound - no attempts to "sound-like-some-acoustic-instrument"
different approach to sound synthesis compared to mainstream subtractive analogs - something I would like to call Natural Synthesis
the whole tone signal path is a pure thermionic valve circuit, digital circuits are used only for what they are good at - MIDI to CV, tuning, etc.
it is designed by a saxophonist, therefore with great demands on dynamics, phrasing, articulation, accents - simply a real musical instrument you have to learn a bit how to play
which means it fully utilizes all MIDI data coming from the wind controller
proper design in terms of earthing, ground circuit and shielding ensures that the instrument has no hum or noise issues
The basic CHRT Synthesizer design is a 2U 19" rack

shipped as a DIY kit, while you can decide on the level of help and assistance with assembly, boards soldering, activation and debugging.

However, the structure is quite flexible and can fit, for example, into some vintage cases. Please do not hesitate to discuss the possibilities.
Here is the CHRT Synthesizer built into a case rescued from a wreck of a 50s tape recorder:

The software part - firmware can be adopted to your needs, e.g. a custom MIDI implementation. Please do not hesitate to discuss the possibilities."
