what the higher notes of the "space bell" preset are doing is called aliasing. it happens when there's frequencies above nyquist in your sound (for retro tech like this it's pretty much safe to assume the nyquist frequency is somewhere around 22.05 kHz or even lower ). These higer frequencies then get looped around and end up in the lower frequencies because the data is kept (not low passed away) and interpolated wrong.

Hey, so the reason why the "Space Bells" instrument sounds weird in the higher notes is because the notes are aliased. The patch itself is quite a complex sounding so the Sound Expander probably can't handle it properly.

@mspenrice

6 жыл бұрын

The expander just connects the OPL to the C64 pretty much entirely passively. The high notes sounding weird are just the OPL operating normally ... Yamaha's phase-shift "FM" is essentially well-controlled sample aliasing after all. And maybe you actually wanted that sound anyway? If not, you could, in a more sophisticated program (on the level of EG Adlib Tracker II) fiddle with the patch settings somewhat (e.g. reduce the modulation rate) until it didn't go quite as wild at the top end, at the expense of changing the timbre of the lower notes. (Though I think such software, and maybe even the OPL itself or at least some of the later members of the family, actually had the facility to automatically adjust the modulation settings according to how far up the scale you were? ISTR there being mention on a data sheet of something like that, which was initially intended for more accurate piano emulation (as it uses fewer strings for high notes than low ... or maybe the other way round, I forget... so has a timbre that alters in the very highest and lowest octaves vs the midrange) but could certainly be used for special effects, or reducing the strength of aliasing artefacts)

Somehow this sounds way better than most of the actual keyboards you've shown on this channel. I can't believe how such a primitive computer can make sounds like these.

@mspenrice

6 жыл бұрын

It shouldn't do, though. Certainly, if they're Yamahas, they will have been using one of these at a minimum (or *maybe* an OPLL, which is essentially the same thing but only one of the channels is fully adjustable, the others have to pick from 15 instrument presets that are much the same as those found within the two sound banks shown here... what you actually get depending on the chip revision... I don't know if they ever made anything based on the 2419 PSG, but it would likely have been a kiddie machine), if not something rather more sophisticated. Casio and Roland each went their own unique ways, but had rather less widely commercialised chips that were roughly on a par; particularly, a lot of lower end Roland keyboards were based around the MT32, and later the Sound Canvas chips, which aren't exactly weak performers. And Casio got into the PCM soundfont game quite early-doors.

SFX Sound Expander is a great example why Commodore bankrupted eventually. It got a pretty decent sound chip, and a big keyboard. From hardware perspective it was good, but lacked touch sensitive keys or even some buttons on keyboard itself. From the software point it was simply a disaster. Why they didn't include software on cartridge? It was more expensive, but it would load very quickly and it would allow for way better software: - They could do a full 128 MIDI instruments, like Windows 3.x did on OPL2/OPL3. - instruments, rhythms, and other static data could be read from cartridge itself, leaving almost whole 64 KB of RAM for user content, - instrument creator, allowing user to manually change FM chip state, - simple, multitrack sequencer, - reading/writing MIDI files on tapes or diskettes. This all could be done in software. Without any further hardware costs. C64 + SFX + Keyboard could become a semi-professional composing tool. Way cheaper than other solutions, more powerful than standalone keyboards. But that didn't happened. Commodore released expensive keyboard that required computer, TV and long loading time to even start working. Standalone keyboards were probably cheaper, way more portable, and even had more sounds, rhythms and other functions. I would say, that in whole Commodore history, it's rather uncanny how they managed to build such a great computers like C64 and Amiga.

So is "Glock" like a Glock 19 or a glockenspiel? I was thinking about dropping my mixtape on C64, and it needs to have lotsa gunshots.

@mspenrice

6 жыл бұрын

I wonder if the cartridge slot on the expander remaps the second chip select line to the first, maybe, physically preventing any conflict between the two devices? It might even be a deliberate part of the design. After all, what if you plug in a software cartridge that uses the same address? And why put two addresses on the port if there was only ever meant to be one cartridge hanging off the back? Compare the external floppy drives of various old computers. Each one individually thought it was "device 1", but you could daisy chain them (generally either 2 or 4 max) thanks to their passthru ports. Said ports remapping the "device 2 select" coming into them as "device 1 select" on the output (and not connecting dev 2 on the output; or, where appropriate, device 3 = device 2, and device 4 = device 3, with dev 4 on the output being N/C), so that the computer would drive one of the two (four) pins active and select just one, specific drive out of those connected, even though each thought of itself as "#1", and the port interconnections were identical with each drive. Simple but smart. Do the same thing with the cartridge port, with a rule that each connected cart's chip(s) are only ever connected to either CS1, or BOTH CS1 and CS2 (if you have a lot of ROM / multiple devices onboard but no dedicated mapper controlling access to them), never "just CS2", as well as mandating that anything with a passthru only connects CS1 internally, and maps CS2 to CS1 on the output, and you have a recipe for being able to daisychain at least two Sound Expanders. Or connect simple one-chip (or at least one-CS) cards into an expander's passthru port. Of course, anything that uses both lines will suffer malfunctions when trying to use the second chip, and software that's too stupid to try the second address if the first one fails will also be incompatible, but those are fairly minor concerns addressed by unplugging the expander and connecting those fussy cartridges directly. Or having some kind of interposer between both devices and the computer which can switch between sending all CS lines to one or the other without having to disconnect (ie, basically the same as any other multi-cart switch box).

I felt tears coming up my eyes, my beloved C64, so etched onto my core, and still amazing me...

there was some sampling software for this set up, it was show to us in the mid 80s in school, i clearly remember it sampling our voices and sounds we made in to a composition that using the large keyboard and i think saving it on to a floppy disk. making quite an impact on me, as seeing the set up again has bought back a lot of memorys. cheers Dan

That's not surprising, seeing as the Sega's 2612 (effectively an "OPNC", or possbly "OPNB-L") and the OPL have a lot of shared heritage. Or more precisely, the entirety of the OPLx and OPNx ranges are essentially based off this chip as a starting point (with the pre-SMD/SG OPNs adding a register-compatible YM2149 core, and in some cases a fairly sophisticated (AD)PCM engine, to the FM part... and one range needing a separate DAC, the other integrating it but I can never remember which is which). The actual FM part works pretty much exactly the same in all cases, just with different features on top of the main 2-operator sine-carrier+single-sine-modulator with hardware ADSR concept (e.g. ability to use 4-op voices, different waveforms either based off rearranging the internal quarter-sine sample to play different ways or just using a wholly different generator, the total number of voices, special effects like multi-part detune, use of the PSG envelope generator, etc). So if you use one of the later chips but don't really push the limits, and just stick to a limited number of fairly straightforward 2-op plus normal envelope voices, it'll sound exactly like the OPL (at the same input clock) no matter which Yamaha FM chip you use. (tell a lie - some will have some minor differences to the overall timbre given the way the actual sound generation works... in all cases there's actually only one operator module that works on each voice, and each slice of a 4-op voice, at a time, which is why the maximum output frequency is so much lower than the input clock... but the more expensive and sophisticated chips store the resulting sample value in a register bank that's then summed and sent to the DAC once per nominal output cycle, whilst the cheaper, cut down ones lack that facility and output the result to the DAC _live,_ using a kind of PWM / timeslice mixing system that relies on intertia within the connected speaker system (or averaging in analogue filters along the output path and/or any digital recorder you might connect to it) as well as the human auditory system to apply a bit of "temporal blur" to the signal exterior to the chip. This is, for example, the source of the famous "ladder effect" bug in the output of the early generation SMD/SG, where quiet tones would acquire a characteristic buzz thanks to poorly matched capacitors on the output stage and thus improper smoothing... which led to several games sounding "wrong" on later revisions that fixed the problem, after composers wrote music deliberately making use of the bug. However, this is something caused in the *output stage* of the chip, rather than the actual FM generation part. The generator itself still works perfectly fine and identical to that of the higher end chips, and if you connected the output of a cheaper chip to a specially-made DAC that incorporated the missing registers and did its own summing to output a clean sample about once every 1/55556th of a second, those simple tones would once again sound identical)

He's keeping it secret!!

man I could listen to these instrument demos all day!

It's great that you had some very generous people donate those units to you. This is pretty cool. I'd imagine the hombrew community could create a demo that utilized the sid+ the Fm expansion for some pretty cool music with 8(3 sid+ 5 FM) channels. I'd love to see something like that. It'd be even neater if it could be utilized in a game. :D

I very much doubt they could have survived the pc and playstation juggernaut. According to ex CBM engineers, the AAA chipset in development couldn't really compete against them, the 3d capability just wasn't there. Pity that CBM usa`s mismanagement messed everything up for CBM uk who were actually doing pretty well with the CD32 and A1200. I still think they would have gone bankrupt eventually though, everything was standardising around the pc, the Amiga line had nowhere to go.

I don't think it is as cut and dry as it not having anywhere to go. Basically, if Commodore could have created an 50mhz 030 + decent 3D graphics chip + SIMM slot trapdoor expansion package that could run Doom etc properly, Amiga would have had a chance. People only put up with PCs for gaming because of what they were capable of graphics-wise, which ironically was one of the main advantages of the Playstation.. Amiga could be simple like a console, but also a fully functional machine. Don't forget that circa '94 AmigaOS was still superior to Windows & MacOS and it took WindowsXP & OSX to finally get where Amiga had been all those years prior.

wow, the sounds on this thing are lovely

wow i knew u were a smart guy when it comes to computers and programming, but i had no idea you were such great musician! i’m super impressed!

AdLib sound player for the C64's SFX Sound Expander module if upgraded to the YM3812 OPL2 chip. csdb.dk/release/?id=119462&show=review

In theory, could a game be made for the c64 that used that device to play its music?

If you know the hardware location you can POKE values into ram for different things in basic. This was how you created music, sprites, changed screen colors etc. on the C64 and many other microcomputers of the time.

There is a guy who made a C64 program that can play DosBox DRO files (which are data dumps of AdLib YM3812 music), on a C64 with a modified SFX Expander (replacing the stock chip with the YM3812 chip). So if he could create such a program in Assembler, anyone with the knowledge of programming could make C64 software or games in Assembler that take advantage of the SFX Expander. You'd just need to find out how the C64 controls it, and work with that.

Absolutely. It would simply be a matter of writing the code to support the FM chip in stead of, or in combination with the SID chip. Like I said in the video, there probably just weren't enough of these on the market to really get game developers interested in writing extra code to support it.

@8-Bit Keys please start modding one of your carts and upgrade it to 3812. Then you could show your audience what a modern DRO player csdb.dk/release/?id=119462 could do. (Wolf3d, Dune, KGB tracks anyone? :) ) And yes, writing a driver for C64 SFX Sound Expander would be as easy as writing an Adlib driver on pc. These chips have only two registers to write to (and read from), everything else is in the programming reference manual.

Absolutely. The only problem really is that it could end up occupying rather more memory and demand more of the total available processor / bus time, to the point that it's impractical to use for anything beyond the simple live-play app shown off here, or maybe a text based tracker. OPL programming isn't exactly super heavyweight, hence its usefulness for DOS games that might have run in less than 512kb RAM, but it's still a grade above that of the SID when you start digging down into all the fine grained functionality. At least, that's the case if you exploit it to the same extreme that a lot of SID programmers did; the unseen advantage with using something like the OPL is that it can actually _reduce_ a lot of the load otherwise placed on the system by coercing the SID into making sophisticated sounds, so long as you program it sympathetically and in the most efficient (rather than most _impressive_ ) way. Most particularly, the automatic ADSR envelope that can be set differently for each channel (and whose settings are retained indefinitely until you next change the voice) requires sending maybe eight bytes to the OPL, which then repeatedly (ie with each new note-start command you send) and without any further data upload produce a volume progression that may have taken four times as many register writes with the SID, each and every time you played a note. And FM voices that give the impression of sounding chorded, or simpler ones literally played as a di-, tri- or tetrachord thanks to the OPL's greater number of simultaneous voices, can stand in place of the arps that would have been necessary to create a similar auditory effect on the SID - again, you only need send 2, 3 or 4 note-on commands for each of those, where with the SID you might have been banging in at least twice as many (apart from the simplest, shortest blip, each arp in an old VGM or chiptune tends to repeat at least twice) or possibly dozens more for a sustained note. It's essentially a tradeoff between how much time (and memory) you can afford to spend setting up your chosen chip before actually playing anything, vs how much is available to throw notes (and patch changes) at it on a live playback basis. Ultimately the overall code for both would probably come out about the same, but the demands of whatever you're running it alongside might favour one or the other. And if you're really canny, you could probably use both in concert playing to the strengths of each, maybe even make an overall saving despite the soundscape being rather richer and more complex.

Great video. thanks again Dave!

the guy that sent you the commodore keyboard sure very grateful because it fall into good hand which is appreciate it.

Awesome stuff, thanks for posting!

Hey guy this is really cool. I had software that you could copy notes from a song book and play them, I really enjoyed my C128 and C64c. I wanted a set up like this back in the 80s but they where hard to find and you didn't have the internet to find things like you do now. money was tight back then during the recession also with high unemployment. I would have loved to have this set up back then, the commodore was so innovative. Really nice, This is so nostalgic. Thanks for doing this video and project. It was great.

the harry potter music 😂😂

This is an amazing video. So impressed with the authors keyboarding skills. My only complaint is the review is only 10 minutes. I would have enjoyed an hour review of this hardware device and keyboard. Thanks to the people who donated the hardware. The viewing public appreciates your generosity.

Growing up with C64 I never imagined that there was even "better" sound for it. However the SID can never be beaten. Loved the Sega Genesis "Synth 2" bank

Thanks for the review. I remember I bought both the SFX Sound Expander + Fullsize Keyboard ...AND...the SFX Sound Sampler. I was a bit bummed out when I found out that I could not use my sampled sounds and play them using the fullsize keyboard. Never the less -- it was a nice kit :-)

wow that's amazing! thanks for showing it off man 👍😎

Such classic 4 Operator FM sounds (Yamaha DX-100). Ahhh I miss the day. Thanks for sharing!

Amazing, wonderful sound!

Nostalgic video for me 🙂 I had one of these, with the full size keyboard, and we actually gigged with it in my band back in school circa 1992! Thinking about it, at that gig, we also set up another 64 in a side room selling refreshments, which would display prices on a full screen scrolling message and - completely unnecessarily! - allow the person serving to use it as a cash register, complete with receipts from my Commodore 1520 plotter! 😄

Very cool. It's amazing that such old devices still can produce such great sounds

Awesome! Looking forward to your presentation of the Roland MT-32.

Man, I LOVE the sounds of this thing!

Such Great stuff u plug it in and it pretty much works :) C64 was amazing for its time
