"Hi all Is anyone using this combination? I'm using Logic/Unitor without OMS now but the SampleCell editor needs OMS. If I have OMS in the extensions folder with the Unitor OMS driver, loading OMS or SC causes all sorts of MIDI overflow problems and made my proMix look like a player piano!" Regards Stephen J Bennett Samplecell does not need OMS even if it tells you it does. Logic can happily talk with it direct from the environment. marius
