i dunno how to use it.. when i try to compress a simple kick drum it ends up sounding like it's coming out of the speaker but when i lower the attack i can barely hear any compression.. tell me how u do this 404 Compressor isn't very sensitive on low ratios imo.

i gave up on the mfx compressor. I only use the vinyl sim compressor.

Roland should add a decent sounding compressor to their update..

I don't have a problem with the compressor effect, it works nice on kicks.
