I've looked around for the interrupt driven music player, but cannot find it (I find cybernoid demo, but it only plays its' own tune)
I entered all of SMB music into Electric Duet. This works fine and sounds great for music when the game isn't being played. I would like to get the interrupt driven mockingboard driver to work so I can play music while playing the game... I can make sounds through the card, and play tunes, but I want interrupts so It can play in the background...
1)where to look for this driver (source code?)
2)how to convert MIDI tunes to the format the driver expects? I think the only person who has midi conversion experience is MJM??
Midi songs that I want to play will be reduced to the # of voices that the MB supports, using an editor on the PC.

Check the disk that shipped with the Mockingboard for the object code. It's
quite short, so disassembly should be straightforward.

That's a good first step--although the music can have more than three
voices as long as no more than three are sounding simultaneously. (And a
Mockingboard can sound *six* square wave voices and two percussive voices
simultaneously, since it has two AY 8910 chips.
My MIDI converter currently outputs N separate streams, one for each
oscillator. Each note or rest is represented as a byte for the note or rest
followed by a two-byte duration to the next action for the oscillator. For
convenience, the separate oscillator streams are concatenated into a single
binary file.

OK, I found it. Strange they would make the player interrupt driven, and not make the demo show this. It just waits for a key, stops music, and returns to the menu. If you delete some of the lines is the MUSIC program, it will continue playing music in the background at the ] prompt

Here is the code, I think some of it may be unnecessary (quick cut and paste). It works in Dos3.3 and Prodos. I know that Prodos has its own interrupt handling scheme... This just writes over the interrupt vector. I don't know what software it would break, there aren't many programs that use interrupts.

I disassembled the Music Construction Set interrupt driven player for the Mockingboard (only to the point where I could re-assemble it, I didn't reverse engineer it yet)

STAFF THE RIGHT ONE IS FOR THE BOTTOM.
So the music file 2 start addresses seem to correspond to this.
$4000 = top staff in the editor. (chip1, 3 channels)
$447e = bottom staff in the editor. (chip2, 3 channels)

OK, it looks like MCS outputs 2 separate sets of data, one for Chip1 (channels 1 to 3), one for Chip2 (channels 1 to 3). I don't see any references to the NOISE registers on the chips, so I'd hazard a guess that the MCS editor/format will not allow noises through the AY8190 (I see no reference to NOISE in the MCS docs, and no commands relating to NOISE)
I don't think these are actually mapped to Chip1/2 specifically. I think I see "look for open oscillator" code in the source.
Your converter has two byte duration.. MCS has 1 byte duration, with Bits 7 and 6 used for control (bit7 set = more notes to play, bit6 = note is tied). Bit 5 is unused, so perhaps in the future I can figure out how to make this bit indicate NOISE to be played.
I will start by creating a simple MIDI music file, and run it through your converter. Look at the output, and see how I can modify your converter to work with the MCS player.
I'm doing this so I can play SMB sound through the mockingboard using interrupt driven routine (MCS file on the Mockingboard Disk1), but if it all goes as planned, Mockingboard users should be able to play converted MIDI files on their apple II computers..

The two data sets are mapped to the treble and bass clefs.
The format in general is based on how the music looks in the editor
instead of what the player needs to do (the opposite of Electric Duet).
For example, the format actually stores "play a quarter note with this
pitch" instead of "run oscillator 2 with this delay value for this many
counts".
I did some reverse engineering of the file format recently. I'll try and
get my notes online...
Would have helped a bit as I was reading the OBJ file, disassembling it... I know the OP codes from memory now, almost understand all of the code too :-)

Right...
ED stores NOTE, Duration, which is actually:
Frequency, TIME
MCS stores NOTE, Duration which is :
NOTE, Time+controlbits
MCS has to look up the frequency in a table.
Time can be 0 to 30, even, so has 16 values

Hi,
Thank you for those. They show the format for MCS editor files.
I haven't been able to generate any songs from the editor that will play with the MCS file on Mockingboard Disk1 (the interrupt driven player). I guess they would have to be converted/ "compiled" into the format expected? Anyone know how to get Music Construction Set generated music to play with the MCS interrupt player?
I tried this:
bload MUSIC, BRUN MCS. no go.
BLOAD MUSIC.OBJ, BRUN MCS. No go.
I tried to OPEN the files that are on MOCKINGBOARD DISK1 in MCS, they will not open.
