What ensemble am I writing for?

I keep asking myself this question. The template file I used for Day 58 is titled "String Quartet, 12 8 time", but I know that it's going to be "performed" by a general MIDI instrument. The American Composer's Forum has a list of tips for submitting work. One of the tips is not to submitt MIDI realizations of orchestral works. I believe it is accompanied by the statement that if one would do that the selection committee may "questions your values."

So where does this leave me? Am I thinking too much? Part of me would love to record a string quartet doing this. But the reality is that I'm not at a music school any longer where I have ready access to string players. Another part of me says "deal with the problems of the instrument--the General MIDI Instrument." When you write for a pipe organ you go in knowing that you can't really control the attack with the keyboard. Dynamics tend to be tiered and achieved by pulling out or in the stops. You have control of the swell as well, but that will be for all the choirs within the swell.

The purpose of the Music 366 project is to generate ideas. For right now I'm writing for MIDI. If things I write can also be transcribed for acoustic instruments, great.
