Jan Ostman Intros mini-TS Synthesizer

Developer Jan Ostman has introduced the mini-TS, a minimal synth he describes as a ‘pocket WASP’.

The mini-TS is a DIY project that can be built in a number of configurations, depending on if you want to use it as a synth, CV controller or MIDI controller.

Video Demo:


  • Clickable rotary encoder and 128×32 graphic OLED display for parameter entry.
  • 3.5mm Stereo jack audio output.
  • 3.5mm Stereo Jack for CV 1volt/octave output and 1 CV input.
  • 3.5mm Stereo jack for Gate output and 1 CV input.
  • PCB pads for MIDI Rx & Tx signals.

Pricing and Availability

The mini-TS is expected to be available at the end of April, with these prices:

  • PCB only $29
  • Full kit $79
  • Prebuilt $99

    1. No need to put a hacksaw in it.
      Just solder the encoder and oled to an ATmega328 and you have a synth module with MIDI2CV and CV2MIDI built in.
      The code is open-source.

  1. Wonder if anyone actually got anything last time- multiple reports that for the 4th time in two years jan failed to come through. Last excuse was cancer, this time it’ll be terrorism, right?

  2. Buyer beware.. this person rips off his customers and does not deliver on his crowd funding campaigns

  4. Jan, I was hoping you could update backers on the Tiny-TS from kickstarter. The negative comments are adding up, and it does not look good.

    A little communication goes a long way. Delays happen, but to ignore people and possibly be taking their hard earned money is simply theft. If you will not be able to fulfill the order, can I please request a refund?

    Kistarter backer (sucker)

  5. I am another buyer, who didn’t received any goods after buying stuff from Jan Ostmans webshop. It really sucks!
