This program sounds a bit like a windchime. It uses no media midi output.

Scroll down and to right, click view source code button. Why does my source code button end up over there, and everyone elses ends up closer to center of screen?

Great example of howto hack the midi ports - nice work .

The source button being on the right hand side might just be because you have no signature.

Ok,
Then how do you guys post your code?

Do you use that code button in the message area?
How do we use that? Do we just click it one time, then paste our code in the message area?, or do we need to do it on both sides of the code?

Get the code in the clipboard, press the code button, then press return to start a new line then paste the code. After that press the code button again to close the style thingy, then it'll appear as a 'code snippet'.

I have noticed my code is in need of a bit of improvement, as the dll calls are not quite right.
Each place where there is a 0 in the dll call the varible type should of been declared with a as long I think.
There is also a missing varible at the end of the 0,0,0 in the call that should be a varible return.

Its varible type should also be defined in the area where there are lines as long, etc.

Think it might be a bit more clear to add a remark after event=144 saying note on or note off message on channel 1.

Also I have found that a midi port of 0 is port 1, so I am making use of port 2.

So the remark for ports should be changed to read -1 = midi mapper 0 to ? your ports.

Lucky for me the sloppy dll calls worked, but this program as is should not be published as an example on how to correctly make the dll calls.

No. The third parameter (first 0) is an (optional) address of a callback function (not possible with DBpro), the fourth parameter is the instance of that callback (n/a in DBpro) and the last parameter contains flags for the callback function (n/a in DBpro)

Quote: "There is also a missing varible at the end of the 0,0,0 in the call that should be a varible return."

No. In order to get a value back from a DLL function (if a function returns a value, that is) you call it like this
result = Call Dll(1, "midiOutShortMsg", HMO, Message)
MidiOutShortMsg returns either
0 = No error
70 = The application sent a message without a status byte to a stream handle.
67 = The hardware is busy with other data.
5 = The specified device handle is invalid.

Ok,
Thanks for your code and comments. Oh, nuts, I put that comment in several places on the forum, going to take me a while to straigten it all out now

Callback not possible with dbp? That is bad news, as the midi tutorials I read say its needed for midi recording.

Not natively, no. But I've heard something through the grapevine...

took me forever to get it to work. I'm looking at possible problems with my ports then I finally find where the trouble was at. midi was on mute, along with my cd audio and line2/mic. dumb computer had half my crap on mute.
