iPad Music Jam: Korg iMS-20, Magellan, GarageBand, Geo Synthesizer, iRIg MIDI and Moog Slim Phatty
Another great video from Marcus, here's what he has to say:
iPad Music Apps are improving fast. Now you can do almost everything using only one device. In this Jam I'm playing with Geo Synthesizer controlling iMS-20 (Lead) and Magellan (Synth Bass and ARP). The arp was programed in Magellan but played by Moog Slim Phatty (using the iRig MIDI interface). Drums by GarageBand.
MIDI Bridge was used for splitting notes played with geo synth for Magellan and iMS-20.
