True Bypass Module (October 2015):
This is a simple relay based true bypass module for 4 channels of audio. It has been designed to handle 4 balanced audio channels, which means that it could also be used as an 4 channel unbalanced stereo bypass switch.
Midi Filter Tool (December 2014):
This device allows the filtering of midi messages on the midi bus. The unit provides a wide variety of configurations while only requiring a very basic user interface.
The unit is designed as a low cost/low part count device targeted at diy-building and is based on a pic16f1829 microcontroller running at 32Mhz.
- Pass only midi note on/off events.
- Let midi sync only through on one single channel.
- Remove everything except CC messages.
- Parse Program Change messages.

This Midi to Trigger interface generates a TTL (5V) trigger signal per note over a range of ten notes. It can be used for example as a midi interface for vintage drum-expanders or as a multiple-trigger generator for a modular synthesizer.
New project added: (04/01/2012)
The Tama TS305 drum-expander, which is a great sounding machine but unfortunately totally lacking of midi control.
Newly fixed: (19 nov/2011)
New project added:(01 nov/2011)
Some circuits require a bipolar power supply. In a portable unit like an effect pedal, that can sometimes be troublesome, since it is likely that we want to power our effects with a standard 9V or 12V wall-wart or batteries and don’t like the idea of putting an AC mains transformer plus rectifiers and filtering into our boxes. That’s where a Dc-Dc converter based circuit can be an alternative:
Project Updated: (01/10/2011)
New firmware version for the Midi-CV/Gate converter. The new firmware allows CC Controller assignement and individual CC Midi channel selection.
Another TR-909 for repair on the Bench. This is actually the 4th TR-909 I am repairing! It came with a problem on the bass drum ‘Attack’ parameter, turning the knob wouldn’t do anything. I thought this would be an easy one and a good cleaning of the potentiometer would cure the problem but not so…
