Jay, when I click on the link all I get is a black screen. But that's not why i wrote.

I ran the par in DosBox on my system and it worked fine. I've been playing with music fractals, as I call them, since the early 90'sor even late 80's, whenever v.15 came out. So I thought I'd play a bit with yours - hope you don't mind. The first thing that jumped out at me was the orbitdelay=1. So I set it way up to 1500. I have found that it is often helpful - and sometimes reveals some really unexpected results - to try increasingly high orbitdelay values.  Unfortunately in this case that causes the video to go off. But this is about music anyway, right? Ok, so after the orbitdelay I turned the PC speaker off, since I have found that playing both together sometimes obscures ingredients of one or the other. Then I thought what about a bit fuller sound, so set polyphony to 9. Changed the wavetype to 7 (just experimented). Lastly, I played with scalemap, and set the values to produce only 1,3 and 5 on the major scale, in this case C,  E and G, and set the quantize note pitch to "yes".

Try toggling the quantize value on and off via the <ctrl+F> for starkly different sounds..

I noticed a strange behavior in ver. 20.04p10. After loading the following par. via the @  command, it plays as if polyphony was set to "1". Regenerating either via "\" or loading a video mode, say SF7, played it with polyphony = 9, as in the par. Repeatedly loading the par showed the same behavior. It looks like ver20.04p10 loads the par and either doesn't recognize the polyphony command or hardwires it to "1".

Can anyone duplicate this?

Peak Variable Bit Rate (VBR) is 770kbps (I think).

Is the OPL command set capable of panning?

That's the version I wrote for a Pentium II, back in 2005.
My video haz x on the left channel, and y on the right channel.
Just about any mandelcloud with connected orbits will work
to make fast, oscillating glides, although I think the sweet
parts are on the right end.

One thing I don't like about DOSbox: It does not seem to know how to 
automatically saturate one processor of a dual core: Saturating both cores 
without a programmer's intent should not even be attempted, because you will 
end up spending a lot of time saving state information. I suspect that 
DOSbox is running in debug mode, because when I manually adjust it towards 
saturating my processor: "cycles: 30000", it is still a lot slower than 
cmd.exe. It is great for capturing stuff, though.

DOSbox is something Micro$oft should've written ten years ago.
It emulates a soundblaster/OPL card, which is not my hardware.
It emulates VESA BIOS, so that FRACTINT works above 360by480.
It can capture audio and video, including a simulation of that old PC 
speaker.
It supports a graphics window, so it does not need to switch into full 
screen mode to operate FRACTINT.
It is configured by default with 16MB of EMS and XMS that fractint can use 
for either enabling users to shell out or for performance with that 2048 
pixel square disk video mode, uh, whenever authors figure out how to 
efficiently spend more time slices.
I can run CWSDPMI under DOSbox for the space that simplgif uses in its 
potential to make gigapixel imajez.
It is under two megabytes, so it is not hours of downloading over dial-up.
It has some keys for slowing itself down, in case a big batch job is 
consuming too much power.
It comes off the net in one-click form; no wizards, no warnings, except when 
I installed the AVI codec.

Overall, it is a wonderful environment, except when it comes to completely 
disabling code for downspeeding, so for now, I will run batch files with 
good old cmd.exe, and when I want to let my friends watch a tesseral 
rendering over a wmv, then I hav no other way than DOSbox.
