iPad Music Software: Alexandre Jean Claude has released Brainwave (App Store link) – a $19.99 clip-based MIDI sequencer for the iPad.

Here’s what they have to say about Brainwave Sequencer:

Bring your melodies and drum beats into life with the streamlined and intuitive MIDI clip editor. Assemble and arrange entire songs with the Arrangement editor. Control up to 16 instruments using the built-in sampler. Use the built-in audio samples to quickly get up and running, or use your own samples for even more creative sounds. Then produce and export MIDI files to be imported to your favourite Digital Audio Workstation software. All this inside of an ergonomic and minimalist user interface that will help get your inspiration to fruition.

While it’s called a MIDI sequencer, it sounds like its features focus on sequencing built-in instruments. No mention is made in the specs of MIDI I/O.
