Rack Improvements

As already mentioned in my Going Modular! post my modular synth lives in a standard 19" rack. In addition to eurorack modules I also have other gear installed into the same rack. My first rack was just two 16 unit high rack rails attached to a Yamaha TX81Z rack synthesizer. It was dirt cheap but not very stable and it was practically impossible to move it anywhere. Something had to be done. I'm not really a carpenter and also didn't feel like spending big pile of money on ready-made studio furniture. I had an unused wooden shelf laying around. One day I thought it actually looks like a side panel for a studio rack. After some measurements I realized it's exactly 18 rack units high! So I went to Clas Ohlson and bought another one and ordered 18 unit rack rails. After that it was pretty easy to build a better rack. Clas Ohlson sells wooden panels exactly 18 rack units high! How convenient! This is the level of carpentry I'm comfortable with! I re-us

Cavisynth SEQ-UFD Sequencer

Control Voltages, Please!  My original idea was to control my synth with Ableton Live and MIDI but it turned out it's more fun to generate control signals with LFO's and other synth modules. The logical next step was of course a sequencer module. The Arduino based Cavisynth SEQ-UFD was the cheapest DIY project I could find and the specs looked good. Sourcing Headaches and Jumper Wires, Part 2 This module build was pretty much a sequel to my Cavisynth Ardurack build . I had lots of problems with the required part types and ended up using all kinds of ugly hacks. With a small module like Ardurack I could live with that but the SEQ-UFD has so many jacks and pots that I just had to make another order to Cavisynth and get correct components before turning on my soldering iron. SEQ-UFD consists of 3 PCB:s. It uses the same  The Arduino Pro Mini processor module as the Ardurack. Panel under construction All PCB's are directly attached to the panel wit
