One of my early works from 2007…
my trusty modified Roland TR-505!!
Apart from a couple of bends (the 10 switches on the top), you can tune all the differnt percussion instruments, plus a master pitch up.
So far nothing new, but there are also two LFOs with adjustable speed and amount which you can route to the instrument pitch.
Down on the side are some Leds which light up if an instrument is played. Each instrument has its own Led and the Bassdrum has 5 Blue Leds for its own.
Warning: Old and crappy video
