hey there. just finished an 8-step sequencer, that controls electrical magnets (which make real-world objects sound and gives the possibility to midi sync them or play them with a midi-controller). arduino is used for ttl and midi synchronization.
have a look at my introduction and a live performance, if you like.
Wow, that's crazy awesome! Nice work.
Where were you performing? Is it a bar/club?
it's a club here in darmstadt (germany) where we live. it was the first real performance with the instrument and we actually improvised the set
