Default OPL FM on the Amiga?
I've heard bits and pieces about some Amiga software using a bridgeboard plus an Adlib or Sound Blaster to get Yamaha FM on the Amiga. Being a fan of FM chips, I'd like to find out more about this, especially if there's information I could use to incorporate that capability into my own programs. I thought I saw an MSX emulator that did on Aminet, but it turns out it actually uses a Picasso IV addon with an OPL3 chip; what software, if any, actually did this?

You could probably port this in a few hours or so.

Well, yes, but A. that would require much more CPU horsepower, and B. Adplug's emulation is...so-so. Most OPL2/3 emulators vary significantly from the sound of an actual chip, for some reason (it's particularily evident in the percussion sounds, but lots of things differ noticeably.)

I'm in kind of a hurry or I'd look it up for you, but there is a thread from about 5-6 months ago that talks all about the use of bridgeboards, which ones did what and what other things you can use them for...

There's this one from July, but the only reference to OPL capability is in regards to a mega-multifunction ISA card that includes an OPL3 chip, which apparently didn't even work :/

Yeah, that's the thread. It explains which bridge boards can allow access to PC cards and what not. I was hoping that would point you in the right direction...

Did you know there is a software FM synthesizer for Amiga?

http://aminet.net/package/mus/misc/fmsynth37

Not real-time, but you can use the samples in other stuff.

Also, it might be easier just to buy an old Yamaha FB-01 for $50 and a $5 Amiga MIDI interface from eBay and then use that. There is even an FB-01 editor available on Aminet.

I know you probably want to go the hardware route, but it seems like it might be more convoluted than the above solutions.

Well, yeah, that would work. My thought, though, was more along the lines of having it as an obscure little option for music output in future game releases, not so much because I need FM on my Amiga.

The Amiga can do FM synthesis, though I'm not sure it was used much, if at all.

interesting thread:
