So, for those of you who are really into the older FM sounds of 90’s PC soundcards (OPL3, OPL2, others)
HOLY COW!
I didn’t see these mentioned. They work perfectly as Audio Units in my version of Renoise. Also, I haven’t noticed any lag. They don’t seem to use up much in the way of CPU, and they have 5 different processors to give you variations of the same sound.
I tried to use the JUCEOPL3 version, but was getting a ton of lag, and I then pestered the person who made it, but they’re not working on it at this time. They then suggested these:
In the center of the page, they have a link for pre-made, ready-to-go plugins for just about any platform.
What is most notable is that they have a few different emulations of the chips. So, you can get some crystal clear or pretty lo-fi FM if you want.
Not just preset sounds here, either. Looks like you can change all of the sounds pretty drastically.
