[Junk Machine] - Transform an old Sony tape recorder into a midi controler
This is an old Sony Tape Recorder completely out of order. He has so beautiful switches, potentiometer allowing interactivity. The first part of my job was to cut everything that I didn't need (a lot of useless wires). After what I soldered new wires connected to an Arduino board.
To grab the data on my Mac I use the serial over USB link. The final goal is to produce sounds and make music. So I have used Cycling '74 Max/MSP and Arduino2Max. As I'm not a great fan of the MSP sound engine, I prefer send Midi data (through MidiYoke - now obsolete) from Max to my favourite Native Instrument Synth : Massive.
Finally, the result of the workshop was presented in public. Here is the video :
After what it seemed more interesting to avoid Max/MSP sending directly from the Arduino Midi data. I used that simple scematic available at ITP Physical Computing.
We also added a lot of new wires connected to other switches allowing more interactivity. It is now a real homemade midi controler.
I have used that version during the DorkbotBRU #2 at IMAL-Brussels in june 2008.
Here is a video of me performing and improvising with the Junk Machine.
It is a work in progress; I'm still working today on that machine. I try to use the sound coming from the playhead of the Sony Tape Recorder to play with. There will be more on that site soon.
