The new dsp-D1 drumsynth chips

February 24, 2015

Want to build your own drumsynth?

As the dsp-G1 was the smallest synth in the world running on a 8-pin DIP chip, the dsp-D1 will be the smallest drumsynthesizers in the World.

Utilising the same 8-pin DIP chips they listen to MIDI CH-10 (or a TTL-trig signal) to play a drumsound.


They have MIDI-CC parameters for Tune, Decay, Pitch envelope, highpass and lowpassfilter.

With a 44.1KHz 16-bit Sigma-Delta DAC audio output they exist in 4 versions, Kick/Snare, Hi-hats/Claps, Tomdrum/rimshot and a combined (4 drum sounds) chip.

The will be available at the DSP Synthesizer store in March.


And this the Adafruit official review of the dsp-G1

Made it to Adafruit

February 21, 2015

I have come far from my Indegogo campaign.

Today I’ve made it into Adafruit stock.

I don’t know if everyone have heard the DSP-G1 and what it can do?

So here is the official demo:

New demos coming for the dsp-G1/dsp-Gplug

Better demos are on the way for the dsp-Gplug VA-synth.

The demos are made by Mr Firechild. A collector and fan of analog synthesizers.
You can find a lot of his work on Youtube.

Ready for shipping!

100 chips in antistatic bags with labels.

Ready for shipping 🙂

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.

The dsp-G1 chip re-polished

November 10, 2014

I got some complaints on rough edges and instability on the dsp-G1 chip.

Someone pointed out that it has “clicky” envelopes.

While some may like that because they are fast, the are now gone in the MK-I rev2 chip. It is now as smooth as an analog envelope!

I also got one comment I really liked.

“It sounds very Juno-like”

That’s exactly what I wanted as it’s modeled after the Juno-106.
