A/ Are you attempting traditional multi-tracking on a limited scale, i.e., close-micing drum kit/instruments/guitar/vocals/etc with specific use mics, and recording multiple mono tracks for later mixdown, perhaps using all eight tracks?
B/ Are you using your 680 'live', to record two or more stereo tracks, i.e. alternate stereo pairs, with maybe some room mics to add later?
C/ Other use (please describe).
D/ How many tracks do you usually make use of?
Any ideas, new approaches, or other feedback would be interesting.
thanks
Dave
