"It sounds really great, both for stereo and for 4.0."
The group 'Get Well Soon' played the album 'Vexations' in a purely orchestral arrangement with the National Theater Symphony Orchestra. The concert should be recorded in surround technique. For optical reasons, a 'finished', elegant-looking mic setup was preferable to a self-built array, as the position of this will inevitably be prominent and video recordings were made.
The Schoeps ORTF Surround [variant of the IRT cross] was preferred over double MS because ORTF setups give a higher 'plasticity' and contour of the musical event, making it sound better as the main microphone. The use of Double MS would have put more tonal emphasis on spatiality, thus one would have been more dependent on the props to get definition. Due to the very tight, inflexible schedule, there was virtually no soundcheck for the support microphones, only the ambience microphones could be tested the day before, but then had to be dismantled and then rebuilt again.
