Title: FM instrument learning resources?
Post by: Domarius on October 25, 2019, 08:11:58
Now that OpenMPT has FM support, what's the best way to go about understanding how to manipulate the OPL settings?

My plan is to just find as many as I can and experiment, but if there is a good place to start learning about how to get certain kinds of effects I'm keen to know.

Is there a good place to find a lot of them at once?

Try searching YouTube for "FM synthesis explained", there are plenty of tutorials and explanations (e.g. this one (https://www.youtube.com/watch?v=vvBl3YUBUyY)) and while they are not specific to OpenMPT, the same principles apply. The OPL chip that is emulated in OpenMPT is just a cut-down version of the Yamaha DX7 with less operators, so most information on the DX7 also applies to OPL.

Thanks, I just needed a good search term :) I was trying "FM instruments" and "OPL instruments".  Ah that guy, I have already watched so many of his videos!

Thank you, this is useful as well.  Already after a quick skim I see something useful like having the modulation frequency integer multiple of the carrier frequency for different kinds of instruments, and fractional multiples for dissonant sounds...
When I was messing with it, all I got was really glitchy sounding effects...

Hey that was enlightening as well! Like the Andrew Huang one - short but really well explained concepts with visuals. :) Thanks!
