Hi,

I've been playing around with javasound and have managed to write a little keyboard app (just like the ToySynth example really), but now that I have come to try something a bit more adventurous, I've come up against a bit of a brick wall. Has anyone managed to sequence MIDI data using javasound yet?? I want to play a looping bar with given MIDI messages on given beats of the bar. I presume that you would use the Sequencer interface, but I've checked all through the API and I can't find any way to start a sequence or to put given messages at a certain point in a sequence...
If someone's figured this out already, I would be really greatful if you could let me know how its done,

Thanks,

Kelvin.

Hi,
Sorry to mail pretty much the same question again, but no-one got back
to me last time, and I'm sure someone out there must know!

I'm trying to use the TimeMBT class from JavaSound so that I can play
looped MIDI data. I create a new TimeMBT object with the following code
:

TimeMBT timeMBT = new TimeMBT(16, 100, 1);

As I understand it from the API, this should create a new timing object
(in this
case one which runs for 16 ticks at 100BPM with 1 tick per beat).
Then by calling the getBeatsMBT() method on this object, you should be
able to retrieve the number of beats that have passed (????).
But when I try this, i.e. by looping and printing timeMBT.getBeatsMBT()
to the screen, the return value of getBeatsMBT() seems to remain at 0
and never increment.
What am I doing wrong?? Do I need to start my new TimeMBT object
somehow?? Please, if anyone has figured this out, let me know,

Thanx in advance,

Kelvin.
