Vst On Mac

I’m having problems getting vst plugins to show up in renoise.
I’ve tried about a dozen or so and only two (multidelay and ExSlMeringue) show up.
I see them all in my waveform editor app though.

Anyone know what the problem might be?

A few that don’t work are:

4Front Bass Module
4Front Piano Module

thanks for the help

Are those VST’s compiled Intel compatible or are they PPC format?
And what CPU-type of Mac platform do you have? If you can find the answers on those two questions, you probably also have the answer on why they don’t work.

they are universal binaries.
I have PPC and Intel platforms.
but like i said… they show up in other apps, just not renoise.
