Arduino controlled casio keyboards and samplers

In this video I'm controlling 2 casio SK1s, a casio SA-38 and 3 SAW
voice memo recorders with an Arduino. I've wired a bunch of the
pushbuttons on the different devices to the arduino and have written
some simple code to sequence it all.
-The SA-38 is useful because it has a pushbutton for each drum voice.
By interfacing this with the arduino I'm able to write and play drum patterns.
-Then I wired up the "one key play" buttons on the SK1s. The SK1
lets you record a sequence then play it back one note at a time every
time you hit "one key play".
-Finally I wired up the "record" and "play" buttons on 3 little voice
memo recorders. These record sound from the keyboards and play
it back. They're pretty noisy but add some nice variety to the overall sound.
The whole project was pretty easy and is very flexible, especially if you're
a savvy arduino programmer. Tutorial coming soon to Make magazine.
