Hi Dietz thank you for the reply.
I am on 64bit and I will give a look at the bus speed. For the time being the projects are quite OK (around 16 instruments in MIR and 24-36 audio channels in Pro Tools). I do not expirience problems.
I did ask about MIR Pro because I am producing in music combine ethnic instruments(PT) and Symphonic sound (MIR). I would love to have all the sound in the same space though.
I have two more questions:
a) when I uncheck Natural Volume and try to re-edit the Instrument Profile the Natural Volume is still Checked though the Volume is changed.
b) After starting MIR some times apears the Ensemble Pro (under MIR) some times does not. Do I something wrong?
