Hi, I am an audio student, and for my semester project in a recording class we have to record a group using at least 16 channels. Most of the class is recording rock bands in the studio, but I was asked by the director of bands to record his new piece. The recording will take place in an auditorium that has fairly good acoustics. The ensemble will be made up of about 30-40 musicians, including grand piano, upright bass (with a D.I.) and full percussion. I have limited access to microphones, but I know I can at least check out 16-18. They would be a mixture possibly including: Shure SM57 Shure SM58 Shure SM 7b AKG D112 Neumann U87 Audio Technica 4050 Oktava MK012 We have at least two of each mic listed above, but only one Neumann. The reason I am posting this is to see what ideas more experienced engineers have. I have searched the internet for ideas, but I haven't found anything overly helpful. It must be at least 16 tracks, and most of the set-ups I have found don't even reach half of that. Also, as a side note, we also have access to a Holophone H2-PRO 5.1. So ideas about surround mixing are also welcome.
