I'm not sure what you mean, this is literally what happens in the original song Either way, I polished the entire project further and finished it earlier today. Currently rendering a video from actual audio I recorded from my PAL Atari 800xl Skip to 1:30 for that part.

Oh man that part was so weird, I didn't know how to simulate it, so I threw in some modulation notes at random volumes to get approximately what it sounded like. I couldn't even understand what the speech was saying, so now "Welcome to Battle Squadron" makes a lot more sense in the context, hahaha

I like this version, compared to the other 15khz edit, the lead is a lot more stable. However I prefer the more unstable nature of the other one you did before. I don't know how to explain, it gives a certain humanised tone If you could harmonise everything accordingly to the 15khz it would pretty good I think, the percussions really lost their power due to this. Moving the lead to channel 2 and 4, then the bass to channel 1 and percussions to channel 3 would allow you to do quite a bit of modulation for nearly no sacrifice. since it will be running at 15khz that means you can get some really good SID bass that way, and having percussions in channel 3 would allow you to use 1.79mhz for the noise on drums, that combined to the low tuning of 15khz would allow you to get really stomping kick drums and snare. Even better you could use the channel 4 for additional harmony on the lead, and channel 3 between drums to modulate the bass and even harmonise it with lower bass for extra crunch Edit: that channel mapping is actually almost exactly what I did, except I ran it at 64khz the entire time, but maybe 15khz could work well...

About done with this one now! I just need to polish it a bit and search for any errors I could have missed. So I think tomorrow this one will be ready for release. This one took me lot of work, seriously! Battle Squadron Intro POKEY WIP4.ogg Battle Squadron 2x V53 RC.xex

Thank you! I know too well 😬 It's surprisingly difficult to get working without sounding like dying cats. Yeah I also noticed the massive output... I have indeed done quite a bit of manual edition, and used a pretty large amount of instruments, but many patterns were recycled, plus I have not yet cleaned it up and optimised either, so I hope there will be some space saved when it's done. Relatively speaking I only have roughly 8 more pattern phrases to do, which like half of the patterns used in these will be copied from earlier parts, so I don't think it will be considerably larger at this point. Having 32kb maximum would be a goal, and theoretically reducing it to 50hz should make the binary half the size of that, which would pretty much match the size of my biggest tunes. Table Manuscrite was a 50(60)hz tune and I think the final executable after conversion was just above 19kb, and was considerably more complex than this one, so we'll see! I can say for sure it's pretty amazing that everything I seem to do sort of break something due to unintended methods

Nice to see this thread again Worked a bit on the Battle Squadron cover again tonight, and damn I just finished transcribing another section that seriously made me curse every possible words I knew. However, I am pretty happy of the result now! It's almost finished now, I need to transcribe a few more patterns, and thankfully it's mostly a recycle job since they will use many patterns I already have done. The RMT2LZSS conversion was once again flawless, still runs at 100hz, and I also confirm this executable works perfectly on real hardware in its current form! So if everything goes well I should be able finish it by tomorrow, unless something else eats my free time away, hahaha Battle Squadron 2x V49.xex

Of course! The kitty was behind all that stuff since the beginning! How else would I make "cat walking on a piano" tunes, or "dying cats screams" melodies otherwise

So while I was doing some other stuff, my AVGCART arrived earlier today (thx again tmp for this great product!) And so I went ahead and tried a bunch of tunes myself and @Spring have done over the last 2 years. Here's some hardware recordings from an NTSC Atari 800xl :3c https://drive.google.com/drive/folders/1DR9NiLmvA7BjhIIz8N4vHIeDQ8-motgS?usp=sharing I'll try to get some PAL tunes as well later, since I also own a PAL 800xl All the tunes I recorded were converted into executables using RMT2LZSS by rensoup, thanks again for this tool man! Battle Squadron will have to pass the ultimate test when I actually finish it, hahaha And with that in mind, love the Atari 8 bit! Good night everyone

You need join channel 1 and 2 or 3 and 4 and have one of them run at 1.79mhz to achieve 16 bit. What you did was joining 1 and 3, which corresponds to high pass filter. Sounds like a keyboard mapping issue on your setup, it behaved like expected for me. Okay this one is currently unknown stuff for me , but I believe it's related to SKCTL bits to enable it, generating tones for the cassette interface if I am not mistaken. SKCTL I believe.

Yep! It does a world of difference, even without LZSS conversion, it would be pretty solid. It actually seems to be pretty good in RMT itself, using the apokeysnd.dll plugin, it seems accurate enough to get a good idea of what it will sound like at export. I believe Altirra is pretty accurate, too. I have not been able to make many tests on real hardware but as far as I know the manipulation is mostly correct on that as well, so that's good news to me

I currently own 2 Atari 800xl machines. Both were incredible deals from Ebay sellers. By pure luck, I even own both a PAL and NTSC machine, because the PAL seller assumed it was defective, so I managed to snag it for really cheap, and it turned to be in really good condition, and never disassembled as well! The only downside is that I currently have no way to load any program on them, or even own any cartridges, so I feel a little limited, but it's just a matter of time, there is a AVGCART coming in the mail, hopefully Canada Post won't be in limbo forever

It is absolutely possible to do stable sounds, but it takes a bit of manual work in the instruments. I am able to make very stable pulse width modulation using new tricks. Tuning and volume can be manipulated on the fly as well, in a similar way.

Yeah don't worry about it, hahaha. It's just something worth pointing out, really. Using AUDF values does work perfectly fine under normal means, however, certain combinations could make it look considerably off compared to the sound we hear due to that. Realistically I think most people won't even care about it, or most tunes wouldn't even do anything weird, I suppose I love his work a lot! A great inspiration as a composer and arranger, soundtracks like Amberstar are in my favourite list. Thank you very much! Unlike the updated version of Actraiser, I didn't actually use his module as a starting point, but made my own new transcription. I hope I won't leave too many errors behind, or ruin it with too much artistic freedom. It really was necessary to do it entirely from scratch to be able to get things to work at all, anyway I'll attach below what I have done currently. As you can see it's still incomplete, but will come together soon. Battle Squadron 2x V45.obx

Thank you! Battle Squadron is coming soon, I am almost done with it, I just need to get a couple lead patterns transcribed, and touch up the entire project file, but overall the song is almost finished, and I hope it gives justice to the original compared to the older cover version As for pushing, absolutely I will continue, this has to be the most fun part, hahaha. I haven't been able to break RMT either, it's a surprisingly robust music program, honestly. I think the only thing that was a bit off from the conversion is the VU meter itself, because all the combinations used were very specific, for example channel 2 always used the frequency 02 while the channel 1 modulated itself to create these bass tones, so visually it always looked like channel 2 was outputting the highest frequency, same for channel 3 and 4 when I used the highpass filter, it started on the frequency 00 each time, to then pitch lower and lower in order to produce that surprisingly rich sound out of it. With that being said, finishing Battle Squadron next is the plan, I think I got plenty of experimental songs started for another day, I really do hope I can bring the WIP I posted above to the next level, especially because original music was never my strongest force.

I had been doing quite a bit of experimental sounds lately I don't really have a finished song (as of right now!) but here's something using very unusual combinations, this sure does some really interesting sounds! This runs at 50hz, and uses barely any CPU. I'm also glad to see RMT2LZSS had no problem at all processing it. I couldn't break it, but I wonder what will happen in the future if I keep pushing the unintended things into it I'll attach my current in progress version to the post. A Permanent Temporary Solution V2.obx

I truly learned how to make music and also sound design on the Atari 8 bit specifically. If I wasn't tinkering around its sound capabilities, I don't think I would have gone as far as I am today, which is not frankly impressive by itself considering I am much of a newcomer (only 2-3 years really) compared to most people here. Also more recently learning some BASIC now that I own the real machine (2 of them due to some incredible Ebay luck!). Pretty fun to use, albeit slow, but that surely kept me busy without any way to load programs on the machines currently.

It is so far! 100hz basically let me run my instruments 2x as fast, so better drums, better melodic instruments, better effects, more precise PWM, that is a blessing to have. Faster means better It can be done in 50hz without any doubt, I already have most of my sound design ready for that purpose. In fact my 100hz drums are just the 50/60hz ones with greater precision and polish to give a nice snap It would simply requires manual edition, but the reduced output by RMT2LZSS already gives an idea of what it could be like, except it was skipping every other frame that were used to update the sound generation, so a lot less polished than what it could be. But that doesn't need any different hardware as far as I know. Pretty sure my stock 800xl would run it exactly the same... But I cannot confirm until I get a way to load my own code on it. Yup that was exactly how it was achieved to figure out most of what I transcribed so far. The voice at the song start was simulated using some Distortion C and High Pass Filter until it sounded good enough for me, the bassline used the same trick except it was combined to Distortion A in the main voice, the C bass was modulating it, so I simply went ahead and tried any frequency that gave a pleasant distortion sound, and thankfully it was also in tune to the bass so that was a win for me! I did my best to simulate the harmony in the bass by using the same filter trick at a lower volume, listening to only channel 1 and 3 with the percussions and arpeggio chords may show how complex I actually tried to make it work The main melodic voice was simple enough, I used high pass filter on channel 2 and modulated the pulse width with channel 4, and used some variable volume levels to give thicker harmonisation in the sound, i might produce some chords or bassier distortion notes if needed later. i've started taking notes for some tables for future reference, and also might have figured more tricks... But that will be tested another day. All I can say is that Pokey Explorer has been an incredibly useful tool for finding all this stuff, and I trusted my ear to mix and match the different combinations, haha. i have to say most of these Amiga tunes are fantastic, and a lot of fun to transcribe on the Atari 8 bit, they let me explore experimental sounds really nicely.

Thanks, I did my best to make the POKEY PWM sound very smooth, and also totally manipulated, not once it's doing unpredictable stuff Adding some additional harmonisation at a lower volume gives a lovely resulting timbre as well. ...Yeah? I am pretty sure I mentioned that I did not finish transcribing the song yet. The 50hz version is not intended to be listened as is either, that was just to test out the reduction feature of RMT2LZSS, which does exactly what is expected in this case. Thanks. I am reassured this is indeed the song I was covering Yes... that is indeed what I did as well, to get effects and harmony sound good. A bit of fine tuning goes a long way to make things that sounded weird to something smooth. I especially like to use detune in a way that make things sound a bit less out of tune in certain parts too Yes but actually no, this is the hacked up 50hz output missing everything the 100hz version did. This is how it's supposed to sound like : battle squadron intro wip2.mp4 Battle Squadron Intro POKEY WIP2.ogg

I does... except it's broken since the instruments are read every other frame, so crucial parts are missed. I don't know how to use 2 tone in RMT... That is still filter and different frequency combinations Anyway I got a small update for tonight before I leave my computer. Found a few mistakes but I corrected them in the bassline... I need to improve the transitions and also add missing parts later. Did the same funny 50hz reduced version again for comparison's sake. It's definitely very possible to do at 50hz too, it simply needs better instrument design, which can only be done manually... I might do a proper reduced version after I finish covering the song.

Thanks! Well 100hz or not, if I am going to make a tune I'll try to make it sound good, hopefully As for the bass, I figured out some new tricks involving the high pass filter and Distortion C to achieve it even in 64khz mode, so I wanted to make use of it as well!

So I have been working on that 100hz Battle Squadron cover... @rensoup Still not finished, but I thought about testing its stability in the RMT2LZSS program. Sounds pretty stable to me! All my special POKEY modulation works exactly as calculated I included the current version in progress to the post, as well as a 50hz reduced conversion... which pretty much sounds the same except every other frame is skipped, that makes my sound design broken, but that also seems to be perfectly consistent! 😮 (By the way, this is not based on Kjmann's module... this is my own transcription I started from scratch, hence the missing parts that are currently too complex to figure out by ear ) Battle Squadron 2x V24.obx Battle Squadron 2x V24 (50hz).obx

Yep again like I said the assumption you had was correct, it was entirely my fault for breaking it, so that is really not a big problem, I simply thought it was worth pointing out In the end everything else worked perfectly, as long as a .rmt is not all over the place, it there shouldn't be any problem.

Exactly as described, it would just play the same song, jump to 0, and then keep going as normal, so Tune 1 with a different intro. My sketch modules were formatted that way (not really on purpose) and did exactly that, both from the RMT2LZSS program, and SAP players parsing subtunes, so I believe this is correctly handled
