It's obvious that this subject has raised considerable interest and that
there's a need to establish what people want from a MIDI/Csound 'interface'
(for want of a better word) because there are clearly different concerns
here.

For my part I am quite aware of MIDI's limitations re composition but am
also aware of its advantages (via sequence editors) for organising dense
material. It's for this reason that I would like to see some way of simply
using a MIDI sequence (without any concern for 'real' realtime) in the
manner in which we are accustomed with standard .sco files - but
transparently. ie you set up some sort of configuration file which maps the
MIDI messages to particular parts of the orchestra and then the MIDI file
may be used and re-edited etc. without the use of any other conversion
software.

Eg. you could assign channel 2s controller7 messages to instrument25 and
make each 'csound note's' duration last until the next message of the same
type - thereby enabling ramping using the standard score convention. The
output can then be assigned to a global variable for use anywhere within the
orchestra.

If this were possible, using the 'mapping' method, you would at least be
able to draw on the functionality of good sequencers (they are, after all,
pretty good graphic editors and offer a wide range of event filtering,
graphic input, patching functions etc.).

Surely I'm not alone in thinking that this would be desirable?
