A site for noise-making toys 

This is the current state of my analogue modular synthesiser. 

Based mainly on Oakley modules designed by Tony Allgood at Oakleysound 

More Cool Pix

These beautiful Oak cabinets were made for me by Mark Smith, after a conversation at the Synth-DIY 2003 Meeting. 

Click on the picture above for more groovy pics, and details of the cabinet interconnects and power supply.

After hearing several of these at the SDIY 2003 gathering, and being convinced by Paul Maddox's evangelising, I coughed up for a Soundart Chameleon. This is a very versatile 24 bit programmable audio DSP engine, housed in a 1U 19" rack box. In essence, you can load different Soundskins via midi sysex and effectively turn the unit into different instruments. For the adventurous, there is also a Developers Kit freely available to allow you to custom program your own soundskins. Checkout the dedicated website for Chameleon projects
