Listening to a sequence!

Hi,


More technical/devices... Suggestions:

1- Keyboard window
Little reference marks along the keys (== "number" of the note/sound) would
be useful. For instance, numbering the white keys:
1,3,4,6,8,9,11,13,15,16... (actually it's A081031!)

2- Tempo
At rapid tempo, it becomes not regular. Tip: open the little instruments
window and let it opened: it stabilizes the tempo.

3- Duration:
Antti:  One sequence for pitch (with various automatic transposing
> possibilities), one for duration (the measure of each note).

Would be very useful!
