Nyström Teases a New Synth

New Synth teaser! video upload by Albert Nyström

Poly6 Teensy 3.6 based Polysynth with patch memory

video upload by Craig Barnes

"Teensy-Poly6

This is a polyphonic synth forked from albnys/TeensyPoly6 converted into a 2U 19" rack.

https://github.com/craigyjp/TeensyPoly6

The analogue interface now uses 6 MUX chips to read the pots and switches so there is no need to connect top the top or underneath of the Teensy 3.6 for the extra analogue inputs required. It runs smoother now as well.

The schematics are upto date now with the latest mux changes.

The synth is built using a teensy 3.6 overclocked to 192Mhz and is programmed in Arduino IDE using the teensy audio library.

Easily upgrade to a T4.1 or even a T4.0 as very few connections are required now. Increase of polyphony is probably available with a T4.x.

How it sounds in the original keyboard form, this sound engine is unchanged.

Albert Nyström Made a Drum Machine for $70

video upload by Albert Nyström

"Here's a Drum machine I designed and built over the last 3 months using a Teensy 4.1 as the main brain.
The total build cost was about $70, 30 of which was the Teensy itself.

I'm pretty happy with how it turned out and I´m considering making a 2.0 version in the future that will be for sale!

Here's a link to the Code, Schematics and more information about the project:

Spaces - a DIY-Synth live session!

video upload by Albert Nyström

"This is a live recording using only my homemade synths. all sounds you hear comes directly from my own synths, except some reverb and delay. The only equipment used that I didn´t build myself is the Digitakt that acts as a sequencer as well as an audio interface.

The modular system plays the arpeggios & all percussion.
The analog Monosynth plays all bass stuff.
The Guitar-synth plays all lead sounds.

Hope you enjoy!"

Some additional details from the comments:

On parts: "My best estimate is around $180 USD, ~70 of which was the Keystep that I used for the keyboard."

On design: "I built everything myself, but took inspiration from exsisting schematics. The filter is based on Mortiz Kleins vactrol VCF, the envelopes are based on Thomas Henrys 555 envelope and the VCOs are built around the AS3340 chip! The effects are the only part I didn't build myself, Search for 'dsp 100 reverb' on aliexpress!"

Homemade analog Synth-Guitar!


0:00 Bass sound
0:50 Saw Lead
2:18 Ambient Lead
3:07 "Guitar" Lead
4:04 Walkthrough

"Fully analog, fully homemade guitar-synth
Built from scratch, based on a few different schematics aswell as a few own designs for some of the functions.
The pitch is controlled by two soft-pots tuned a 4th apart, just like a guitar.

The body is mostly made of stained plywood and the knobs are made of dowels that i cut and sanded to size!

The synth is accompanied by a couple of beats I made on my digitakt!

Hope you enjoy!"
