Gakken sx-150 arduino hack number two: Adding MIDI and Audio out


I finally got around to finishing the hack to my Gakken SX-150 mini synth. On the first part I added the ability to be controlled by Arduino through a virtual software midi port. On this iteration, I added a real midi in port and I also added a 1/4′ plug audio out, to make it more usable with standard audio equipment. For more picture you can take a look at the flickr set.


The MIDI part consisted in combining the Arduino MIDI IN circuit and the Voltage Control Circuit described on the first part of this hack.
And, this is how it sounds!

FAWM 2008 – My entry so far

FAWM (February Album Writing Month) is a yearly community challenge to write 14 songs (a complete album) in February. 14 songs, that’s a song every 2 days, at least. This is the perfect excuse for me to produce stuff, no matter if it is good or bad. Here’s what I’ve done so far (this list will get update as February goes along.)
