Developer Intua has just announced BeatMaker, a sampler / sequencer for your iPhone / iPod Touch that allows you to record and make beats on the go. It appears to function similarly to hardware like the famed Akai MPC sampler, allowing you to create loops and beats and play them back in real time. BeatMaker also includes a three-channel EQ, synchronized delay and a bitcrusher, for those of you who like to rock the 8-bit sound.
No word on availability and pricing yet -- Intua is, like almost everyone in the Apple world, waiting for more info on the iPhone App Store. Developer Mathieu Garcia also says that, though MIDI won't be in the initial release of BeatMaker, it's planned for inclusion in upcoming versions, along with Open Sound Control, the successor to MIDI that's becoming standard in more and more music-making apps these days.
