Subject: Re: Re: Metronome enhancements?

Just returing after a week off I was happy to see
Matthias' and Linus' reply on the subject. Let me add
some comments:

Well, I did spend some time on the subject, checked
the code etc. Probably we can go for a shared action
here :)

Some questions:
- how did you create the values for the static
unsigned char sound[]?
--> reason for this question is that I have access to
one of those high-end metronomes (see: where I
could record the sounds from.
Also a talking (one two three four....) one is around

No. You just need to look at the logic of the BPMs -
quarter gives the base BPM, eighths are 2*BPM,
eighth-note triplets are 3*BPM , sixteenth-note are

Well, I can imagine percentages of volume per
quarter/eigthth/eighth triplet/sixteenth of a main

As I said above, I'd be happy to join in and do some
programming here (yes, once upon a time I finished my
computer science studies), but as I don't want to
destroy anything I'd be pleased and all of us would be
on the safe side if we could go for a shared action
here. Let me know what you prefer.
