Hi XavierB,
I see that your question gets a high amout of views, but no answers ... this might be due to the fact that your requirements are quite specific.
In general, it should be very easy to work with any kind of audio source in MIR Pro, as long as you keep a few caveats in mind:
- Sounds which already include reverb and/or room-information of their own will need special attenention - in some cases, it might be wiser _not_ to use them with MIR Pro.
- You will need to use one of the General Purpose Instrument Profiles for any other signal source than sounds derived from Vienna Instruments (Cardioid is a good starting point for most signals). Of course you won't get tailor-made Character Presets, Natural Volume for these signals.
- Pre-positioned 3rd-party orchestral libraries may need some kind of "re-balancing" before they are put on a MIR Pro Venue's stage, to counter-act the "built-in" panning (Vienna Suite's Power-Pan might come handy).
Kind regards,
