Looks and sounds nice! What are the system requirements?

Hey, awesome skillz and good tunes too! :) Just think about what if you had _two_ channels... Try the TED chip!

Great sounds from the PC speaker!
Will try it on my XT soon.

Rockin' tunes - hats off for the truly oldskool system requirements, too (and the detailed lowdown on the tech/tricks)

Still in total disbelief about how far this pushes the classic monophonic PC speaker sound.

It runs fine on new PC with USB boot.
a large amount of work, respect!

Tried it on real hardware... didn't work 100%.
On my 286, both SB.COM and SBX.COM crash with an "Internal stack overflow". It works for a short while, but there's some random noises, even when you're in the menu, not playing sounds.
The display updates are also somewhat haphazard... They freeze from time to time, then get going again.
On my IBM PC/XT 5160, neither SB.COM nor SBX.COM play correctly. The music seems too slow, and there's random/garbled noise.

My guess is that the code inside the timer interrupt is too slow in complex parts, leading multiple interrupts to get 'piggybacked' onto the stack, eventually crashing the machine.

However, I do agree that this music is technically possible on even a stock IBM 5150 or 5160, given properly optimized code and bugfree code.

Thanks a lot for report! The problem is that XT class machines is kind of unobtainium here (super rare and worth a leg), and emulators don't do justice regarding actual hardware timings (tested in DosBox and SPCXT). Weirdly enough, I had reports it works properly on some below-286 machines. Timer interrupt isn't much slow, certainly should fit by itself. Maybe some issue with calling back the standard DOS timer handler (it calls it at normal 18 Hz rate). Will collect more data and look into this issue, to get it fixed eventually.

Yes, that could be. Perhaps if the machine state isn't exactly the way the standard handler expects it, it may cause issues. Or perhaps the handler itself leaves the machine in a different state than when you called it.
The standard 18 Hz timer is in the BIOS, and different clones may have different behaviour there.
For example, the 286 I use, has a routine in there to read the turbo button status. I found that out because the turbo button stops working during certain games and demos, because they replace the handler altogether.

Anyway, I'll gladly help you to test and debug the code.

Thanks! Trixter gave me some tips and advices, including a segment override movsw quirk on 8086 that I wasn't aware of. I applied some fixes, should help with both issues - please test if it works indeed. Download link is the same.

Just tested, this seems to solve the problem on the PC/XT 5160, works fine now, and sounds great on that big loud speaker that IBM puts in there.

My 286 still has the same weird beeping in the menu and stack overflow crashes, so that may be a different issue. Might be related to the weird BIOS timer handler routine I mentioned earlier.

Brilliant! I enjoyed the tunes and it was nice to see it work in such a limited machine. The downside is that I also have some issues on my "real" hardware (an A2088/4.7MHz commodore bridgeboard connected to my Amiga), it plays correctly sometimes more than half a minute but then some random beeps start to sound and the music finally breaks. I can try with a faster v20 cpu to see if it helps... I hope you can fix the little bugs and produce more releases with this sound engine in the future :-)
