Rene PICSynth Bass Pedal Inspired by the Moog Taurus 3

via PICSynth where you'll find additional details.

"Pressing the low C pedal produces a very low sounding - earth shaking tone (like a T-Rex is roaring)...The +/- detune setting produces a nice 'chorus' like tone."

"PICratchBox connects to PICnome via 8pins LAN cable.

And then, this picture is PICratchBox 4ep top plate design."

PICSynth releases MIDI controller

"Build a PIC based DIY midi keyboard for under $30, and by using free VSTs (virtual instruments) you get a powerful music creation system.

Features
* Support for 4 Octave keyboard
* Octave range switch
* Expression control knob
* 2 general purpose analog controls knobs
* Low current drawn from 9v battery"

"Demo of me playing my homemade PICSynth. It has 3 oscillators and an arpeggiator.
The website details how a home constructor can build their own PICSynth.

"The GrooveAxe is a simple to build project that uses a Picaxe [PICSynth] microcontroller to make looping drum patterns."

The Csaba DIY and Electronics - dsPICFun 2

"This board can generate four Control Voltages with a 12-bit DAC7554 for outputs and has four inputs hooked up to the ADC port. It also has 4 potentiometers hooked up to the ADC board two buttons and a rotary Encoder for values and settings.
It has a LCD port, DCI port , UART and SPI/I2C . Now this is where it gets interesting : the flexibility of the board is imense as it be configured for MIDI, RS-232 or USB. DCI port can take any Audio CODEC and I assume some memory handling might be possible with another µCU via the SPI port. Giving us a great and flexible dsPIC based Audio development sytem.

My Idea is to have some wavetables that leave the digital domain and are feed into a SSM2044 VCF that then is controlled by the CV of this powerful µCU dsPIC33FJ128GP708 running @7.37MHz."

Microcontroller Synth Roundup

"Microcontroller-based sytnhs are a little odd because in general these little chips aren't too powerful; I'm pretty sure a lot of modern commercial synths use rather hefty DSP chips. But they're nice because of their simplicity of design, and I think most audio DIYers are more familiar with microcontrollers than dedicated DSPers."

You can find the roundup on The Experimentalists Anonymous Weblog. Included are the AVR based synths and the PICSynth.

PICSynth V2

via picsynth on this electro-music.com thread: "PICSYNTH V2 chip is available. This allows variable pitch adjustment of oscillator 1 as well as having very accurate higher note frequencies.
Frequency modulation is now possible.

New samples on the picsynth site.

variation1.wma
This was made by varying pitch of oscillator 1 using the new detune control, a little inspiration followed around the beating notes. Oscillator 1 is also being fed into filter cutoff frequency for interesting peaky filter effects.

spooky.wma
I fed a LFO (sine wave) into PIN2.

The new pic18f1220 chip is cool and performs the task much better than the 16f628 did ! I hope to have a few pictures of other peoples picsynths soon.

Shoebox Fractal Synth on synth-diy where you will find more images and info.
"I had once stumbled upon Catweazle's fractal synth. In the circuit benders forum it seemed that the project had come to a halt. But recently I realized that it was going on elsewhere.! Here.
Also, the files can be found in the forum or in http://www.gjcp.net/~catweazle/PICsynth/
There are two schematics and lots of mp3 samples if you want to hear how it sounds."

PIC based Analog Synth you can build

"Features
* Dual oscillator mono synth
* Really easy to build using just 1 custom programmed PIC chip, 4 ICs and single 12v supply
* All circuits built on veroboard - no printed circuit board making skills needed
* PIC based dual oscillator and digital keyboard scan
* Analog VCF/VCA/Envelope
* Waveforms : sawtooth, square (with pulse width adjust), triangle
* Tuning presets : in-sync, out-sync, detune1 and detune2
* Expandable, first two modules shown below.
A real analog synthesizer to build using easy to get components, capable of a wide range of sounds. The two oscillators can be detuned for that classic synth sound."
