None that I know of

A m audio oxygen v8

A m audio keystation 88

A roland td 20

That is all

No drivers were needed for the td20 and and the maudio stuff was pluged in selected and worked no problem

I only use the computer for audio recording

I have superior drummer2  installed but have had no problems with it I was useing it in sonar from the first day I got sonar with no problems apart from that there is nothing else that is mid that I use

The problems happen with out even my keyboards pluged in or no superrior drummer on so I dont think it coulod be any of them well at least I hope not since they havent been pluged in lol

Norrie

I have never used midi a lot so this is me just geting in to it now.
