This might be something really simple, but I just can't figure it out...

I'm trying to do a little program that plays soundfiles using MIDI input, and polyphonically (using #PB_Sound_Multichannel). The problem is, when a midi note message comes in, I have something like

channel = PlaySound (0 ...

Hey, I changed the InDev value from 1 to 0 and now it works

einander, thanks so much for this great stuff - can't wait to start working with this!

Procedure MIDIin(hMi, wMsg, dummy, Data1, Data2)



Ah well, there it was: the code at the PureArea archive says


Procedure MIDIin(hMi, wMsg, Data1, Data2)


Now it starts up ok, but I don't get anything when I push the keys :(

What I want to do is to trigger and control certain events ...

hi,

could anyone please help me a bit, I'm trying to get started with this midi in stuff... I found this "Midi_In&Out" example from PureArea, but it hangs with "invalid memory access (read error at address 1)" at the MIDIin procedure. the other example (MidiConnecter.pb) seems to work fine.

i'm ...

Thanks Rescator, I think this will be a huge help! I didn't even
know about threads previously, but if they work like I understand,
looks like a playback thread will solve one or two other problems
as well... I was just going to ask if there is any way to keep the
program from halting when moving ...

Same here, so apparently it counts 1/3579545's of seconds regardless of hardware - ie. does exactly what a timer should do, and seems to do it pretty very well too!

But yeah, it must be a compatibility issue - and probably an isolated case at that. I'll update the CPU & soundcard drivers to see if ...

Derek,
that's very interesting - I haven't realized that there could be THAT big a difference, although I normally always do put the states into variables, just for convenience... however, I have to use WaitWindowEvent(1) keeping this whole thing together so I'm afraid it's no help this time ...

well i can describe briefly what's inside the loop:

- 4 x soundVolume, soundPan, soundFrequency
- 4 x if...and...and...PlaySound
- some ExamineKeyboard and Select for buttongadgets
- twelve (12) times the following kind of bit (checking trackbar and checkbox values) - this should probably be ...

might be time to start optimising any code you can

i don't know if i can, i have about 100 gadgets in this damn thing and i need to monitor them all, and there's really not very much else inside the loop...

but nice to know that it's a Vista problem after all apparently anyway

I'm using WaitWindowEvent(), it seems to work better here (on XP)

Well now: I tried to strip the program down to just the event loop - getting the time and playing the sounds - and it sort of works under Vista...

so I took the full length program and commented out everything inside the event loop ...

OK, I changed it to GetTickCount_(). XP works fine as before, Vista
got even more messed up than with ElapsedMilliseconds(). Now the
program takes up 30-40% CPU all the time and memory usage
increased to 11000...

what about this - does anyone think this could have to do with the fact that the ...

thanks for the tip paul, i'll try it with something else (GetTickCount is it?), and maybe also check the driver updates... i'll report back when i see what happens

this is pre-installed Vista so shouldn't be a problem there...

took off all the extra crap right at the start, and I'm not running any virus shields or anything (while btw on the much slower XP machine I have F-Secure running at the same time and even that doesn't slow the timer down!) - in short i ...

OK, still on this topic:

I'm still using ElapsedMilliseconds(), and I just ran the program on both machines with the same soundfiles (small) and same parameters, and had a look at the task manager:

old machine (XP): memory usage 8500kb, CPU usage stays between 0-2 percent, no noticable difference ...

well... thanks, seems to work, but i'll have to rewrite all my programs to implement this is there documentation somewhere for timeSetEvent_?
