Glitch Delay – more progress

Posted on December 7, 2016

I’ve been working pretty hard on my glitch delay module the last few months. As you may remember it’s sort of a cross between my previous AudioFreeze project and a digital delay. It consists of a delay line with a write head and a read head. The difference being the read head is basically looping a […]

Work in progress Glitch Delay

Posted on November 3, 2016

So I’ve been beavering away on a new Eurorack effect based on the Teensy board again! Added a very rough demo, which starts with a dry loop, then entirely wet glitch effect. Dials from top to bottom are Glitch window size Glitch window speed Feedback Dry/Wet mix     The effect is sort of a […]

Build your own AudioFreeze

Posted on July 17, 2016

I’ve added the Gerber files to GitHub so anyone can build the module if they like. As a disclaimer this module should be seen as a prototype. IT HAS NO POWER FILTERING OR SHORT CIRCUIT PREVENTION, if you plug the ribbon cable in the wrong way you may damage the board and potentially your other modules. […]

AudioFreeze Fascia complete

Posted on June 18, 2016

To be able to mount my AudioFreeze PCB in a modular case I needed to craft a fascia. I decided to use laser-cut acrylic. I haven’t found anywhere in the UK that does bespoke Aluminium cutting, and, due to a kind friend, I had access to a laser cutter! I created a vector image in InkScape, […]

AudioFreeze Prototype built

Posted on June 15, 2016

After a few hours of soldering my PCB is populated and it works! There was no way of knowing for sure without building it, and as this was my first PCB I had some doubts, but thankfully it’s all good. The LEDs and corresponding resistors have yet to be added, I wanted to wait for the […]

PCBs have arrived!

Posted on May 28, 2016

My first ever PCBs have arrived, possibly the first of many? Can’t wait to get the first one soldered up. After that I need to design the Eurorack panel, current plan is laser cut acrylic. Will post demos as soon as it’s made! Thanks to Hackvana for fabricating them, a highly recommended service!  

Making PCBs

Posted on April 19, 2016

So, I’m ready to progress with my AudioFreeze project, and move from breadboard prototype to permanent module. I didn’t relish the thought of transferring the circuit to Vero board, it would be possible but fiddly. I toyed with the idea of fabricating my own (see http://www.instructables.com/id/How-to-Etch-a-PCB/), but a friend made me aware that you can get very […]

MIDI pedal complete!

Posted on February 29, 2016

After some soldering and drilling I’ve finished the final version of my MIDI pedal. I’m really pleased with how it’s turned out. I’ve used it live now, and it was really handy having LEDs to show which pedals I had active, and I can now control Ableton’s looper more accurately. I’m less convinced by the […]

MIDI pedal prototype complete

Posted on January 9, 2016

The prototype of my USB MIDI pedal is now complete. What you see below is prototyped on breadboard using the TEENSY development board, running software which I wrote in C/C++. It has 4 fully programmable pedal switches (either toggle or momentary), and an LED which flashes in time with the midi clock. This clock LED […]

MIDI Controller Stage 2

Posted on November 9, 2015

It works! I had made a couple of foolish errors, due to looking at the wrong pin schematic for the TEENSY (I have 3.2 not 2). But I now have a working, single pot controller. With this mastered I’m hoping that adding more pots should be straight forward. I’d also like to include an LED […]
