The JVS-01 Semi Analog Synth Chip

February 22, 2017

New chip for 2017!

The JVS-01 is a semi-analog synthesizer voice in a 8-pin DIP.

The chip implements a Juno-style synthesizer voice with a saw integrator DCO, 24dB lowpass biquad filter with resonance, DCA with 1024 level amplitude control and a 512 stage DDL Chorus.

The chorus can be turned on or off.

The signal chain is 96dB 16-bit DSP and the DAC runs a 1MHz PDM signal.

Internal processing is done at a 66KHz sample rate.

The chip can be used as a voice chip for an analog voltage controlled synthesizer.

All CV inputs handle positive 0-5 volt input and the DCO pitch conforms to a 1v/Oct frequency response, 5 octaves, 61Hz – 2KHz range.

Here is the panel layout of the upcoming 2-operator FM firmware for the Tiny-TS.


Tiny-TS firmware update handles CV inputs

December 26, 2016

The Tiny-TS is only monophonic and doesn’t have an arpeggiator.
But with the v1.1 firmware it now also handles CV and Gate input from a sequencer to make it play arpeggios.

On startup it checks if the Gate output is grounded.
If it is it reverses the CV/Gate ports to inputs.

The Gate now triggers the envelope and the CV input shifts an octave up on the keyboard.

You can now play arpeggios.

The Tiny-TS project now on

Tiny-TS 2-OP FM Firmware Released

December 16, 2016

There is now an alternate firmware for the Tiny-TS credit card synthesizer.

It features a 2 operator FM sound engine instead of the original Resonant peak engine.

The Tiny-TS is available at Kickstart







Tiny-TS, 95% funded with 23 days left

December 15, 2016

The Tiny-TS synth is 95% funded on Kickstarter with 23 days left of the campaign.
So pledge the final 5% and you will most certainly get your Tiny-TS synth.

When the Kickstarter is funded additional firmware will be released.

One firmware makes the gate output into a MIDI output instead for controlling MIDI-Synthesizers.

And also a new sound engine with a 2-operator FM synth.



The TinyTS – Also on Kickstarter
