I am a little unclear on the technology options for the new AQA AS. On first glance, there seems little difference between the two technology options. Besides the fact that one uses at least some MIDI, what exactly is the difference? For the multi-track/close mic option, does the piece chosen have to be something commercially available (ie, a cover version), or does it have to be original (their own composition), or either? What does it mean by the "initial recording of four" parts? - Does this mean the students first record 4 tracks with no effects, then mix them so they sound good - this giving them the marks? Can a student use one piece for a solo (or ensemble) performance, and then record/mix that same piece for the technology option? Thanks.
