It may interest you to know that virt expressed great surprise in hearing the "polyphony" version of his music when I converted it for him a few weeks after 8088 MPH came out. His remarks were essentially that it sounded "odd" because it was composed quite specifically for PC speaker, although he liked some parts strangely better.
Rad. It's always interesting hearing something devised for ye olde PC Speaker played out through other sound hardware - especially as it gives it room to breathe.
Actually sounds like pretty competent Atari ST music, just without any noise channel and no arps or other high frequency effects. Quite cool that it managed to convert down to single-channel screecher so successfully.
Now I wonder how well you could cram those tunes for the SN76489 (not only present e.g. on the ColevoVision and Sega Master System, but crucially also the PCjr) replacing one square wave for the noise channel.
+RetroSwim The pitch of certain notes sounds slightly off in your video. NTSC and PAL Amigas have slightly different clock speeds, resulting in slightly different divisor values to reach the same sample frequency. I'm quite sure our tune was composed for PAL (as most MODs are), and changing the setting may fix the pitch-issues.
+Scali Bohemiq I just tried playing around with the PAL/NTSC switch in Inertia Player while listening to test1.mod, and I honest-to-goodness couldn't hear any difference. But I trust that you know what you're talking about, so perhaps it's a DOSBox issue with the player. I'll try it on my 5x86 box and get back to you.
NTSC Amiga uses master crystal of 28.63636MHz, PAL uses 28.37516MHz, which is almost a 1% difference (0.921% in fact), which would be enough to be audible as a change of a few cents. Or in other words, 2837.516Hz is F +27c, 2863.636Hz is F7 +43c, so that's about a fifth of a semitone difference, enough to be discernable as a detune if you have perfect pitch or otherwise well tuned ears. However, as all the samples are detuned by the same extent, it would be a bit like the change from 24 to 25fps playback when showing movies on PAL TVs. You'd only really notice if you were extremely familiar with the original version, and maybe even then only if you did a side to side comparison. What's more likely though is that if the original MOD was timed up using unpitched samples running at a particular speed, and the note (and effect) _timing_ hasn't been changed in line with the sample replay rate, there could be some odd inaccuracies and glitches arising from that. Samples clicking because they cut off a little early or start looping by a small amount/running on into a different one, for example (or worse still, looping at the wrong point, which will bring a lot of noise, maybe buzzing, into the final output). If you've got a relatively short patch of only 1000 samples length, the speed change could still introduce a timing error of about 9 samples either way, which is more than enough to foul up the perceived quality of a piece. If all the timing has changed in sync with the sample replay speed, it shouldn't be a problem other than for the most extremely pedantic ;) because it's only about a fifth of the speed change imposed by PAL movie playback, and maybe 9x what you get when showing films on colour NTSC screens... only if things have been retimed unevely will it mess it all up. If you've switched back and forth between the two modes and there's no obvious difference to be had, we can probably safely assume the replay engine is doing a good job of keeping everything in sync even though the master clock might be a percent or so out.
"test1.MOD" is not a true ProTracker module - it doesn't play correctly in the ProTracker clone, nor in "mikmod", nor in uade, and uade is the benchmark, as it fully emulates the MC68000 microprocessor and the Paula chip in a cycle correct manner.

The last song sounds strange, probably because it's interpolated even though it shouldn't be
Man, Inertia Player, that brings back some memories for me. The very first module player program I ever used.
If my calculations are correct, when this baby hits 8088 miles per hour, you're going to see some serious *!?*
Great. It reminded me that my desperately tries of polyphonic music programming on ms-dos
Is thera a polyphonic version of Area 5150 too?
Swinging Waste sounds like it was made for a Tandy computer or PCJr. played like this. ^_^
This deserves more likes...
I think you should have set Inertia Player to PAL speed instead of NTSC.
+Scali Bohemiq That switch doesn't seem to do anything, or at least the effect isn't noticeable. Maybe it only affects playback of certain formats?

***** Makes sense. I'll try it when I get home this evening.

Sounds like the Tandy sound chip
That's probably the playback option chosen during the initial setup screen?
@@gwenynorisu6883 Read the description.
It sounds like Tandy because there are 3 square channels,like the Tandy chip
It isn't the Tandy 3-Voice audio as this demo's soundtrack goes below A2 (109Hz).
so in pc speaker you can make the music very fast to make 3 virtual channel playing square wave, similar to tandy in many ways
Some parts of it I heard from one of minigame in Google Santa Tracker, is it original tune or something else popular?
If you could put a link to the VOGONS URL that begat this in the description, that would be great.
+Jim Leonard Doneskis, added it to the description! :)
Cool vid :)
and it quite impressive what they where able too do with the tech, speaking about Sid/chip tunes in general
Still not a big fan of the no roads tune but this does sound better than the pc speaker at least.
Noice Music
Well, those yamaha chips had an AY8910 inside, so nothing "impossible" but clearly needed, because wasn't usedfrequently.
i would love to see how you creat these and also the hardware you use
+chip1gray Just used DOSBox for this one sorry! :P
does anyone have the original sheet music or midi? i need a high quality version of the credits song...
I don't understand, is the "bodged" three/four channel through the PC internal speaker? If it is it is very clear.
I saw some instructions where it was note, off, note, off, off, off. Why 3 offs?
sometimes people accidentally add more than needed. it does nothing. just a small mistake.
like from 2 -3 D
Roland?
