I don't mean to be rude, but I'm not sure you understand the comma. It has nothing to do with combining types of instruments. It's a problem that exists even with a single instrument. The problem is that, even on a single instrument (say a piano), if you start on some note (say C0), going up seven octaves should land you on exactly the same note as going up twelve perfect fifths (C7). The problem is that the precise…
I understand that pianos have to pick a frequency for each key. I wonder if there is any effort in electronic instruments to produce "better" frequencies on the fly? I'll explain: On a piano hitting C+G plays something close to a perfect fifth. An electronic instrument could move the G slightly to produce a perfect fifth when that key combination is played.

#111It's not just a matter of 'better' frequencies. It's trivial to have a softsynth or something similar set up to use just intonation (and many modern composers have experimented with this), but that has practical problems of it's own. Problems which were the very reason that equal temperement took over in the first place. This page has some wonderful examples http://www.nesssoftware.com/home/asn/homepage/teaching/exp-l...
