The TSynth is a DIY, low cost 12 note polyphonic synthesizer that you build yourself. It can store and recall patches, and is controllable via the front panel or MIDI (CC, patch recall, pitch bend and modulation wheel.) It can accept MIDI via a USB Host port (plug your MIDI Class Compliant keyboard directly in), USB Client (appears as a MIDI device on a computer for your DAW) and classic MIDI 5 pin DIN. It has both analogue and USB digital audio. TSynth is a teensy-based do it yourself, low cost polyphonic programmable synthesizer. This kit is a minimal kit with only the circuit board and display. All design, a full bill of materials, and documentation is open-source on Github.

This includes a display, display standoff, display mounting hardware, TSynth main board with surface mount components, and a TSynth front board.

A full kit is also available for purchase. Documentation can be found on github.

What you get

This is a kit with only the PCB with SMD parts, the front panel, and a tested display.

You are buying the following, as seen in the pictures:

  • The front panel
  • The main PCB with SMD components already soldered: two 4067 multiplexers, 6N138 based MIDI In opto-coupler, buffer for MIDI thru and all resistors and capacitors (the green PCB)
  • A tested IPS 80x160 ST7735 SPI colour display
  • A 3D printed standoff for the display (the small black plastic part)

You only will need to buy the Teensy and Audio Board yourself (Teensy 4.1, Audio Board Rev D). The open source code, build guide and plans for the enclosure are all available.

Before you buy

Please read the Build Guide before you purchase! Although it isn't particularly challenging to solder and build (two hours), this is not suitable as a first project.

In use

You will be surprised at the range of sounds and the capabilities of TSynth! It is all running from one ARM Cortex M7 running at 600MHz and in use, you will find it works reliably with the firmware supplied by ElectroTechnique. It's features rival many more expensive desktop synths, but remember it is supposed to be a fun build using just one micro-controller and not an alternative for buying something from a larger brand.

Specifications

12 note polyphony, 24 oscillators, velocity sensitive, versatile PWM control, detune, white & pink noise, pitch envelope, dynamic & chord unison, XOR and cross modulation, state variable filter, separate LFOs for pitch and filter, two envelope generators, stereo chorus, patch save, delete and recall, three MIDI IN choices, MIDI thru, USB digital audio out...... A long list of features is available from the website electrotechnique.cc
