Yeah. Not to hijack the thread, but I bought the Atari ST for two reasons: it had MIDI, and it was one of the personal computers with a whole megabyte of RAM built in, addressable in one go. Imagine that — a whole megabyte!
Back to the thread topic.
I am interested to hear about trackers on Android and iOS, too. Especially Android right now; I’ve swiped a Galaxy Tab from work for a couple of weeks, and want to see if the music production scene on it is any less bleak than the last time I used an Android tablet.
