Midibox Sequencer |
|
|---|---|
| Intro | This project is a step sequencer based on Torsten Klose's Midibox Sequencer design. I've built it in 2004, before I had a Sequentix P3. It's a cool step sequencer that's very easy to use, but I have to admit that I haven't used it much since. As with many similar projects, it's a lot more fun to build than to use... Some impressions from the building process are below... |
| Electronics | The electronics are built upon a modular concept, with a core board including a PIC controller and a range of peripheral controller boards.
|
The controls and displays are all mounted onto matrix boards. This makes sense for a one-off production, but it did result in a serious cable mess...
|
|
| Final Product | Finally, everything was mounted into a wood case with a foam frontpanel. It looks perfectly decent from a distance, although one notices the not-so-perfect finish of the panel when looking closer.

Oakley Filtrex |
|
|---|---|
| Intro | The Oakley Filtrex is a 24db/oct analog filter based upon the traditional Moog design concept, but with a few twists... Tony Algood designed the filter and sells the PCB with a few of the difficult to find parts. With a proper front panel made by Schaeffer, the result is a professional looking box that sounds awesome. |

AFM-1 |
|
|---|---|
| Intro | The AFM-1 is an analog filter module designed by Tony Hardie-Bick. It's a modern interpretation of the Korg MS-10 and MS-20 filter. Tony provides a PCB including a single mono 12dB LP / 6dB HP filter, but it's designed to cascade well and can easily be set up in a stereo configuration. My own version is based upon four of these filter boards, providing a stereo filter with two stages. I kept the configuration as flexible as possible: Each stage has a complete set of input/output jacks, enabling patching the filter as two independent stereo filters. Cascading the filters in series can either be done internally, bypassing the input pre-amp stage for the second stage, or through the normalised connectors, allowing to tweak the gain structure independently. Tweaking gain on this filter is crucial: It really comes to life when you overdrive the filter and turn up resonance. I then use the second stage to tame the sound - hence individual gain control is crucial. According to Tony, this is the "ultimate configuration" of the filter that nobody else has tried so far... ;-) |

The Hand |
|
|---|---|
| Intro | The Hand is an on-going project to develop a low-cost cyberglove. At work, I'm playing with Cybergloves costing absolutely insane amounts of money, so I felt the need to show that someting similar can easily be implemented with a low-cost DIY approach. So The Hand is essentially an opera glove instrumented with three bend sensor, a 3-axis accelerometer and a small buzzer. The system is implemented using an Arduino as the main controller, Lilypad accelerometer and buzzer modules, and three resistive bend sensors. This is work in progress. The prototype works and sends sensor data to a Max patch. |
