miker Posted January 14, 2007 Share Posted January 14, 2007 Here are some tries to play AY/YM music on XL/XE. The player was done by Swiety and it is at its alpha stage. Thus it's a bit limited, and doesn't play some effects (e.g. sid/digidrum and other timer-based features). Here are some songs to listen either on emulator or real stuff. What do you think about it? 1 Quote Link to comment Share on other sites More sharing options...

Is this the soundchip emulation of the atari ST? I think the main thing to work on is getting the player into the right pitch, it plays very detuned pitches. It seems like a normal 50hz programming (usable in the background of a program), so will the extra features take more CPU time? Quote Link to comment Share on other sites More sharing options...
miker Posted January 14, 2007 Author Share Posted January 14, 2007 @analmux: yes, it is exactly - these are normal .YM files - just uncompressed. The main problem is when playing very different freqs on different voices - the music goes totally messy... Also, the player is not so new, but Swiety said that he has no time for atari. Maybe he improves it some day. Quote Link to comment Share on other sites More sharing options...
pps Posted January 14, 2007 Share Posted January 14, 2007 Wow! Well done! For sure there is a lot to do (e.g. the timing is sometimes very strange), but the start has been made Quote Link to comment Share on other sites More sharing options...
raster/c.p.u. Posted January 15, 2007 Share Posted January 15, 2007 Yes. It's interesting. But, IMHO, Atari SID player by Swiety is more amazing for me. And I will be glad if this SIDplayer project will be finished, please. Some old beta versions of SIDplayer works superb - exists some new version? Many thanks and greetings to Swiety and his great works with sound emulations. Quote Link to comment Share on other sites More sharing options...
miker Posted January 15, 2007 Author Share Posted January 15, 2007 The latest available version of sidplayer is 1.00beta. However Swiety also tried to emulate C64's lowpass filter (two other .xex files in the archive). All the works on SID/AY players are stopped for now. If Swiety finds enough time, he may do something more. Enjoy! Sid.zip Quote Link to comment Share on other sites More sharing options...

That means: 2 SID channels and 2 Hardsynth channels together. Remember: Hardsynth don't need much cpu time.... just some timing correct programming! The SID emulation does the roundup in the tune and the deep notes also. Edited January 15, 2007 by emkay Quote Link to comment Share on other sites More sharing options...
emkay Posted January 15, 2007 Share Posted January 15, 2007 A combination of "emulated SID" and "Hardsynth would make it a thousand times easier to bring the POKEY voices in tune. Quote Link to comment Share on other sites More sharing options...

This beta1.00 (also beta 0.97) doesn't play some great SID modules which older version 0.93 played well. (for example THRUST.SID, ACESHIGH.SID or CHIMERA.SID) Quote Link to comment Share on other sites More sharing options...
explorer Posted January 1, 2020 Share Posted January 1, 2020 Hi! I've been looking for a way to play YM files on the XL / XE (POKEY) for three days. The original music is created in the Arkos Tracker 2, but has no export options for the POKEY. I could try to make a player from the music file format of the Arkos Tracker, but I think it's just what Swiety has done. Is this project still going on?

Seems you don't know what it all is missing The best solution would be to have the YM files directly ported to a 16 bit POKEY Tracker, well, if you find one. It seems easily possible to convert the file data to RMT ( for example) , to have a rather low resource usage. But then you may encounter the 8 bit resolution problem and the slight detuning in RMT, and no 16 bit support for the main melodic channel, to get 1 to 1 conversions. Players that "convert" on the fly were possibly too resource expensive. No problem for some simple game, but it could cause hard times, if a game needs all possible CPU resources.

Heaven/TQA Posted January 1, 2020 Share Posted January 1, 2020 Miker did some YM ST conversions to POKEY... I would go for this way (manually converting). Those SID and YM players take the whole CPU processing time to emulate those sound chips. and a lot of RAM I bet (at least SID). so not sure if that's the way you want to go (for title music only?). Music is the easiest here to fix in the project as we have enough music guys around to help. but my advice don't waste time at the moment. Just make sure that you reserve a RAM block for the music so you can fit it in later. If you choose RMT than the question is about sound effects. Again Miker can help you here or Tebe or Tezz et al how to solve that. Quote Link to comment Share on other sites More sharing options...
miker Posted January 1, 2020 Author Share Posted January 1, 2020 Hehe, nectrobumbing rules! I'va managed to dig unpacked AY-player from atari.area server. However, it hasn't ben developed further and in order to try it, you have to prepare .ym file, unpack it, and attach with binary header from $0800. Note: it may work only in emus (or with some smart-loader). Sorry for all inconveniences. Attached one plays TOKI music. ay_emul.zip Quote Link to comment Share on other sites More sharing options...
Poison Posted January 1, 2020 Share Posted January 1, 2020 (edited) Is possible, for better emulation, use stereo and splice channels ? You will get 4 16bit channels L1+L2, L3+L4 and R1+R2, R3+R4 - it can be very powerful tool for AY, YM and emulation for terrible SID ( Yuck ). It is only idea Edited January 1, 2020 by Poison Quote Link to comment Share on other sites More sharing options...
ivop Posted January 1, 2020 Share Posted January 1, 2020 @Poison That's exactly what sid2gumby does. Sorry for the weird assembler format. Haven't converted this one to mads yet. Another idea I had recently, is to write the converters on a PC and output SAP-R, which can then be compressed with dmsc's SAP-R compressor. sid2sapr, ay2sapr, et cetera 1 Quote Link to comment Share on other sites More sharing options...
explorer Posted January 1, 2020 Share Posted January 1, 2020 (edited) All these ideas are very useful to me. More detail of the problem: the music of the game is in Arkos Tracker format. That program was chosen because the versions for Spectrum 128K and MSX2 have the same PSG chip, and a player available. I have already exported the music to YM format and made a player for 68000, for the Atari ST: Months later, the ggn programmer made a a direct aks player, the files being much smaller than the YM, which are nothing more than dumps of the YM2149F records, I suppose that they are very similar to the .AY files. As there is also the player for Amstrad, it is logical that its version is being made now (all three computers have the same AY-3-8910 chip). The music is here: https://github.com/fjpena/sword-of-ianna-zx/tree/master/artwork/music https://github.com/fjpena/sword-of-ianna-msx2/tree/master/artwork/music Because the size of the game is very large, there are only versions for 128K computers, or using an external cartridge (Dandanator), so in our case it would be logical for the music to be made for a stereo POKEY. I still have to do many accounts to see how much RAM it will consume in the XL/XE, so everything is possible. Naturally, the ideal is that it can be played on machines with only one POKEY. Thanks, @miker and @ivop. I will check your programs. Edited January 1, 2020 by explorer links Quote Link to comment Share on other sites More sharing options...
emkay Posted January 1, 2020 Share Posted January 1, 2020 (edited) If someone plans to make a game for the Atari, OF COURSE it has to run properly with one POKEY. Using a second POKEY for some enhancement like stereo ... well, no one will forbid this In theory it should be easy to get the data, because it is build on a dedicated tracker. Asking the writer of the tracker for a description might not hurt anyone? On the other hand, simply writing the notes from one tracker into the other, is also possible. The tunes are not that big. The next problem is to have a tracker that is using a 16 bit channel for the melodic part. the low notes that were used over all , could be reached using 15kHz on the other channels. RMT doesn't allow that. A native tracker used on the real thing, could be the solution. I wonder , if there is one.

explorer Posted January 2, 2020 Share Posted January 2, 2020 Wow! I just discovered that the Arkos Tracker already exports for 6502 with a player for Apple II and Oric (for the same reason: they all have the AY chip). I will see it, because then the issue is how to adapt the records of the AY to the POKEY. With the code ay_emul I guess it will help me.

miker Posted January 2, 2020 Author Share Posted January 2, 2020 (edited) @explorer To remake those pieces of music it's better to rewrite then on Atari. I've downloaded Arkos Tracker 2 and music form Spectrum version, listened to some ingame ones and the, although a bit strange, seem doable. Yeah, not without some tradeoffs, but still.
