@ emkay, Why not doing a new try of your own compositions? 99% of your hundreds of tunes are all existing non-PoKey tunes, ported to RMT songs.

PoKey can indeed also play RING MODULATION!!! PoKey can indeed also play RING MODULATION!!! PoKey can indeed also play RING MODULATION!!! PoKey can indeed also play RING MODULATION!!! PoKey can indeed also play RING MODULATION!!! .... Just to repeat it 100000 times, people will get used to call it the right way: RING MODULATION ... and finally forget the original word ("high pass filter").

Yes, sorry, I was just puzzling. I mean GTIA 'palette', NOT 'patch'. And having a better look, now I see indeed that it runs heavy DLIs.

@ popmilo Do you use only PAL blending, or also GTIA patch changes, f.e. running DLIs every scanline? Anyway, it would look interesting when also scrolling through the whole Sonic level.

Interesting progress. What about expanding the tables to try a minimal SID-filter emulation? IMO a detailed one wouldn't really be needed anyway, because also different older & newer C64s sound differently. (I'm also living in the Netherlands and currently my age is 34.)

Yes, seeing it another time. At 1:28 it explicitely tells us that it uses VBXE mode. I'm partially blind

Movements & software sprites look interesting. But some parts of the trailer were played with VBXE mode turned on? Or am I wrong?

And here some simple BASIC example tests ...

(1) I don't like flickering (2) In some cases you can get interesting effects when using the GPRIOR=$30 setting, thus also the 5th player. Mixing COLPM2 & COLPM3 & COLPF3, then you already have 7 colours. F.e. use player 2&3 and all missiles to get 7 colour grid of 8 bit width. Now you can turn SIZEP0 & SIZEP1 to $00, turn SIZEP2 & SIZEP3 to $01 and turn SIZEM to $55.

If I were the admin, I would delete this and many similar threads. Then it would be far more easy to find back all the useful topics.

@ Heaven Thanks for the links

Why is its size that large? I would expect 16 kB at max, when using uncompressed gfx + some movements e.a..

You're right. But now I remember that the pokey.dll itself was just wrong at that time. Here you can play 'Instrumentarium.sap': http://asma.atari.org/asmadb/search.php?q1=2&q2=Bernhard%20Pos%20(Analmux)&q3=1 Played by the real machine: Thus this pokey.dll version had the following errors: - Sawtooth wave was totally messed up - Distortion 2 at 1.79 MHz had a wrong key shift - Triangle wave was totally messed up - Distortion guitar (16 bit) was totally messed up - Clarinet (16 bit) was totally messed up - 2-tone-filter was not enabled

IIRC the SAP data layout does not contain 2-tone-filter, sawtooth wave, triangle wave, STIMER control and SKCTL control. So SAP is far incomplete for simulating real PoKey music anyway, and that's a pity. It is always better to find the original XEX files instead and don't use SAP at all.

A sub-sub-forum focused on this and similar topic subjects would be nice, when it's a bit off-topic with respect to the standard A8 itself.

A sub-sub-forum focused on this and similar topics would be nice, when students and professors are just theorizing about a bit off-topic subject.

How does it look using a PC with emulated A8 at 4741% speed, emulated oscilloscope and octal PoKey to have stereo 16-bit volume only?

In this case a 2*2 matrix is enough, so in reality it is 2D. The player doesn't jump/move in a z-direction and a vertical angle. It looks more like a direct cartesian product 2D*F (trivial fibre bundle). Let's call it pseudo-3D. Real 3D needs more CPU time, and vector gfx is a nice solution. Also the moving background gfx is not real 3D. Only sometimes full SO(3) effects are used in case of objects, in front of the pseudo-3D background, which do not move in this case.

@ Foebane: I'm quite confused how you're able to compare your works (which are only in your memory and phantasy 30 years ago) with my ideas, fine-tuning note2pitch tables & ideal approximations, distortion interests, my compositions and arrangements. @ Worms: meaning the german city 'Worms' is just a few hours from my home. @ Triace: Your first PoKey works sound very interesting. Indeed I assumed you used standard RMT, mono. RMT: RaSter music tracker, done by RaSter / Radek Sterba. Unfortunately, he died a few years ago. But his website is still on the internet: http://raster.infos.cz/atari/rmt/rmt.htm I studied al kinds of undocumented PoKey features, and wrote a few RMT patches. IMHO my patches RMT Patch 3 and RMT Patch 8 can give eccentric / exotic positibilities.

No, I assume Foebane (see post 29 here) means: http://a8.fandal.cz/detail.php?files_id=3391

I'm very happy with the unambiguity of PoKey chips w.r.t. different atari 8-bit computers. There are different C64 versions, with different SIDs: 6581 vs 8580. The sound difference, compared to the real filters, is clear.

Where can I find "Worms" (and its PoKey song) on the internet? What's your age by the way?

Well, when using 15 kHz mode you have pure bass & heavy filter / synth. Then you can still use other modern PoKey tricks to play high notes which are IMO still acceptable. You can use distortion 2 and 12, 8-bits, 1.79 MHz. What about f.e. a 15 kHz 8-bit bass trio + drums (from 1:40): And what about my newest tryout?: http://atariage.com/forums/topic/234769-rmt-patch-8/?p=3178857 Here I used my newest alternative pitch tables: http://atariage.com/forums/topic/234769-rmt-patch-8/?p=3173080

And of course another one (Wagner / Rescue on Fractalus)

Interesting clothes you have
