Yes, regmacroediting quickly is the way. If 4op was easier to make single instruments that'd be the way to go since it worked pretty well, but keeping it simple and small.

Did it go well with the consonants so far? It's hard to produce colored noise with the OPL I think. Maybe you can cheat by flipping some values quickly with the CPU to add some additional rumble for browner noise for "k" etc.

Pretty fun though. Yea, I have SAM for my SID. I just like that the OPL3 sounds a bit more like the speakjets, SID sounds like a really crunched version of the doppler radar voice, though I think sam could be expanded to an 8580 specific mode and really make use of that analog filter.

haha, yeah you probably stumbled onto VOSIM. smile

i think most of us that mess with synthesis come across it, but that dude got to name it. smile

it also seems like how the SID chip did speech synthesis too. I think it was 4bit? so 16 levels? i dunno - i think it's just modulating a "click" very fast.

it's more fun to just play around, but reading about it can point in interesting directions.

this is a pretty nice VOSIM explanation, but the original paper is available online too.

Using the opl3 sounds way different. Much noisier with the macro automation. The low bit controls for things like feedback and the multiplier seem to be the most limiting factors. we'll see what comes out though. made a few so far, but it's gonna take months to perfect. Give it a try! It's pretty fun finding the weird things you can make. I'll post an advanced macro editing tutorial on youtube soon.

surprisingly making consonant sounds is the hardest part.

this helps a lot for the rest:

To model speech, then, you would probably figure out the most significant amplitudes of the frequency components of speech and feed that data into amplitude controi register/s. Here's to hoping it's somewhat more advanced than that, though! I doubt it's anything like Chowning's FM speech.

This paper seems quite relevant, but I don't have access to the whole thing. The abstract actually gives a pretty good overview of the technique though:

There's also this, which is for vowel sounds only:

So I was curious if anyone has played with opl2's CSM mode or seen any of it used in a game or program or anything.
I'm trying to make 4op speech macros, really hard to find actual documentation on anything of the sort. Just finding
crazy calculus equations from stanford university and learning how CSM works on other machines. I think it could feasibly be faked in Adlib Tracker 2 and made into an instrument bank. If anyone else feels like contributing the idea's basically to try and model sounds as instruments
