Glad it could be of help. I can't wait to see what you'll come with

Scancodes probably come form WinAPI too...
Now I just need to get the playback routine called every 49.4Hz (the closest speed to Mega Drive I got using PCs PIT in QB version).
What a big bite... I need to digest it a little...
EDIT : if anyone's interested in the DOS verison, here's some OLD version : http://www.spritesmind.net/_GenDev//for ... .php?t=220 (latest is 0.4a, but its used for commercial stuff...)

Part one .MID File format
http://www.petesqbsite.com/sections/exp ... .html#midi
Part Two - Processing of a midi file with interpreted results.
http://www.petesqbsite.com/sections/exp ... ogramming2
Part tree - Actual formatting and sending of MIDI messages to the MIDI devices.
http://www.petesqbsite.com/sections/exp ... ogramming3
The last one shows how to use the API to open MIDI channels formulate and send MIDI messages of all types (note on/off, and the likes.).
For good timing, the API again in Windows, see the QueryPerformanceTimer function for details.
Hope these help.

I'll try to understand the ON TIMER emulation.... I have zero experience with windows programming... and I will not do any pmode DOS stuff...
And for MIDI, writing to $330 won't do in Windows... only in DOS it seems... and I DO NOT want to use any libraries. And I need something very basic.. I don't play MIDI files, I just send in some MIDI commands... stuff like Key On/Off, Program change, Parameter change etc.... I guess Windows API comes here...

as those found in QB libraries.
2.-You can emulate ON-TIMER using a background thread. See code .This solution won't compile for DOS...
3.- FB can write to port to $330 if your present compiler can do it. But this is not likely to work in other people's soundcards. For alternative solutions see this thread

1) How can I get keyboard scan codes ? INP(&H60) doesn't do anymore...
2) There is no ON TIMER anymore... I need something that executes part of code after (insert time here)... in QB45 I just wrote new value to PIT and got ON TIMER(1) to do what required...
3) I can do MIDI anymore by just writing to $330 ($ means HEX here... I'm 68K programmer... Mega Drive / Genesis kicks @$$)...
