This is a really cool-looking app but I find it too hard to do anything useful with.

1) The transport controls are way too small
2) Transport controls are too dark to distinguish which button is which.
3) Pressing the stop button doesn't stop recording, if in record mode.
4) Transport needs to have "start of track" and "end of track" buttons. I don't want to be forced to use the Track Editor to simply move to the beginning or end of a sequence. Incredibly annoying.
5) The Track Editor (sequencer) is archaic and completely counter-intuitive.
6) For some reason, I can't record over a track if I make a mistake. I have to delete the track and create a new one.
7) I can't delete a mistake on a track - I have to re-record the whole track. No punch-in?
8) There's no simple loop function.
9) Buttons for New Track and Delete Track should exist in the track editor, not only in a pull down. Annoying.
10) No graphic representation of sequence (see #5)

I'd like to see dedicated transport controls, perhaps on a floating palette (hopefully it could dock.) On my iBook, the tiny transport buttons are practically unusable. It may look cool, but form over function fails. Why does it need to be so small, anyway? Strictly speaking, I'm not typing an e-mail while I'm recording a sequence, so why not enlarge the "keyboard" a bit?

A good "freeware" toy, but in no way worth $20.
