So be it! I’ll do it my way (nothing to be afraid of, really), and let’s see how things go. As to the format, basically each track has its own (from 16 bit to 32 bit-float, from 44.1 kHz to 48 kHz and from mono to stereo with all possible permutations) so I have decided to make a 24 bit/48 kHz version of the final master which can be reduced to whatever you like afterwards (just had to pick something, and it makes sense as a starting point for downwards conversions). Still, if some of you want to send me compatible versions directly out of the mix, you are welcome to do so. Otherwise it’ll be done properly, no worries. I can also make diverse exports in classic formats, just request what you want if you have particular needs.
Talk soon people!
