4op-FM

April 10, 2008 | 10:39 am

Hey yall it’s me again.
I have been working a lot with the 4opFM from Pluggo. I have been having bad
luck trying to get a good bass out of it. I get a lot of patches that seem
like they should sound nice when they are low, but the response isn’t that
good on the low end. And for the life of me i can’t get any of those patches
to not have snaps and pops. My question is if there is a definitive guide to
programing with a 4 op. I know the DX7 was great at those nice bass sounds.
But it was 6 op right? Are 4 ops just not up to the task?

I haven’t used the 4opFM patch, but 4op FM synthesis – in general – is something that I really enjoy. (I’ve mainly worked with a Yamaha DX21 and Native Instruments’ FM7.) It’s fun and versatile.

The book linked below was written with the DX7 in mind – so a lot of the examples default to 6op instructions – but they offer conversion tables for readers using 4op synths. No matter what, it’s really helpful in terms of getting a mental hold on FM synthesis concepts. :)

This is for Pure Data but I found it the other day while looking for algorithms to try…

I made a bunch of examples from this book in Max. They are part of the CNMAT MMJ Depot here:
