The new Poly-8 Voiceboard

November 28, 2014

After I get this new voiceboard manufactured I’m afraid the Jupitar-X will no longer be monophonic.

The board has 8 SQR/PWM, 8 SUB and 16 SAW voices on a single board.

A MCU scans the matrix and resets the SAW integrators.



Name change on new synths

November 26, 2014

To not step on any trademarks the names have changed to JANO-X and JUPITAR-X.



A small earthquake with the release of the Juno clones.

Thanks all for the interest.

The release date for the first batch of 40 synths is set to 1/1/2015.

You can order them at

Make sure your fast because there could be 2 or 3 months until the next batch.




And the extremely tiny Jano-X synth

November 24, 2014

The 65x60mm all analog JU-X monophonic Juno voice..

Just CV/Gate, PWM-CV and Pitch-CV 0-5v analog inputs. 

SUPERSAW unison setting for the SAW waveform.

Great for sequencing and use with external filter.

$70 including shipping.

Oscillator with SAW, SQR/PWM and SUB waveforms.
SUPERSAW unison setting for the SAW waveform.

LFO and AR-envelope.

DSP filter with LPF, HPF and Resonance setting.

MIDI input for note on/off.

5 volt CV/Gate input for oscillator. Frequency range 65-2093Hz (C2-C7).
5 volt CV input for filter cutoff.
External audio input to filter.

Great analog sound.

$330 ready built or $235 for a kit including all parts, knobs, box and frontpanel.

The Juno synth in an 8-pin DIP

November 14, 2014

The chip is really hitting all barriers in popularity.

With an analog VA-synth in just an 8-pin DIP it’s like the 21 century’s SID-chip.

And just MIDI-in and audio-out so anyone can build a MIDI synth.

It’s really cool. It’s really DIY.

And it sounds just great!

Very Juno-like.


Stocking the dsp-G1 chip

November 13, 2014

A rumor says that Adafruit is stocking my chip.

Let’s see if it’s true 🙂

Anyways, here are the waveforms of the morphing oscillator.

Very Juno-like.

Soo simple

It takes about 1min to breadboard a MIDI synthesizer.
That is just how easy the dsp-G1 chip is to work with.

Anyone can do it.
