How to get computer to play my songs written in Visual Basic 6.0?

Musical notes in Visual Basic 6.0: I wrote a program that writes random songs, and I'd like it to be able to play them, so I don't have to plunk them out on my bass to know what they sound like.
I looked into the Multimedia control, and as far as I can tell it doesn't seem to do what I want. Ideally, I'd like access to the sounds in my sound card, but I'd be happy with plain old-school beeps.

Response by poster: Currently, it just knows the names of the notes and how many beats to hold them. It doesn't write them to file in any particular format. Screenie.

In order to play the notes, you'll need to feed them into some kind of software that understands what a 'note' is. You might want to write some kind of save-to-MIDI functionality.

just a nit, but a random collection of notes does not a song make. thank you. you may now ban my sorry ass.

Dear high priest of quons, I believe he is seeking to listen to them to determine if they've got any song-like bits worthy of keeping, perhaps to help him refine the note-generating ability of said software. Maybe after many iterations of refinement, he might have himself something that can produce actual worthwhile songs.

Does Zel offer you a path to MIDI zen? If your program can write out the musical notes in the Zel language, Zel can play them.

Response by poster: dhartung, Zel sounds like it might do the trick, thanks, I'll check it out.
Just to confirm, though, Visual Basic offers no innate ability to produce a tone of a certain pitch and length? I searched and couldn't find it.

http://www.officecomputertraining.com/vbtutorial/tutpages/page41.asp - Unfortunately, VB has only one intrinsic statement which will play sound. The Beep statement requires no parameters and will play the default system sound, usually that annoying 'ding'.
writing midi files isn't the easiest thing in the world - you'd be better finding a library to use or writing a simpler format that something can translate (zel sounds good).

Absolutely....I often use the "random pattern" function on Reason to see what the program comes up with. Randomness is interesting when it comes down to repetitive loops.

Response by poster: Andrew, thank you for the confirmation. That was the only thing I found, too.
Longish description of program follows - don't mind me, I feel somewhat chatty today.
FWIW, the note choice isn't fully random. Each possible interval has a weight, essentially a number of lottery balls. The program determines the notes that it could choose that are in key, then makes a roll based on the weights each interval has been given. As currently set up, it is more likely to pick semitones and tritones if they are available, because that's the sort of music I like.
After listening to what it comes up with, if I like or dislike a particular part, I can reward or punish it, which will increase (or decrease) the weights used for the intervals that were used in the part, making them more (or less) likely to be chosen in the future.
Also, it is aware of the time signature and is more likely to hold notes longer if the number of beats per bar is higher. The not yet implemented complexity will modify this as well.
Eventually, I intend to add a library of all possible 3 to 5 (or more) interval sequences, ie riffs or melodies, which can then be rewarded or punished with the rest. After a non-trivial amount of time spent training it, it should be able to come up with songs similar to the ones I write.
As well, some more basic things like accidentals, modulation, and notes smaller than a quarter might make it in there as well.

Best answer: OK, there is an answer here, but I'm not sure of how proficient a programmer you are. Microsoft provides several audio APIs for dealing with sound.
Someone has translated the MIDI API into Visual Basic (look halfway down the page. Which I think accomplishes what you are looking for.

- MCI (Media Control Interface) is mainly for controlling devices, starting CD drives, media players, etc.
- Wave form Audio These API's are mainly with dealing with audio waveforms and playing and transforming the waveforms before releasing to a specific device.
- And finally, MIDI API This API provides what I think is the clearest path to accomplishing what you are trying to accomplish, basically playing musical notes through your speakers, modulating, and extending them.

Response by poster: Patrick, that last link looks to be exactly what I'm looking for. Thank you so much.

This thread is closed to new comments.
More detail about your program would probably be useful.
