Here is a video tutorial and online review for iSequence for the iPad, made by the good folks over at DubSpot.
Want the brief lowdown? Here goes:
- Virtually unlimited instruments, due to the ingenious way that iSequence deals with tracks.
- Excellent timing. Most iPad apps have horrible timing, but this one gets it right.
- Song export makes it actually useful to make beats on your iPad.
- Needs more effects.
- The instruments are SO general MIDI.
