I am just loving my new MIR SE. I have just completed a commission for a large orchestral backing track, and MIR makes the orchestra sound so real - much more 'air' and cleaner relationships between the instruments than using a convolution reverb and panning for the individual instrument.
Do you know what would be great - if MIR would accept an audio file as an input. I am thinking here of a vocal recording (I am and Opera singer) which can be placed on the stage in MIR and moved around just like the midi instruments are.
Meantime, I will just carry on using my convolution reverb on my vocal track to mix it in with the orchestral backing the best I can!
