Changing instrument sound then back again within same song.

Can you switch instrument sounds back and forth within a song or are you stuck with one sound per staff?

More than one instrument can play at the same time, they just can't begin at the same time:

This depends on the capabilities of the performing synthesizer, but the commonly used Microsoft GS Wavetable SW Synth is able to perform this. Some synths don't react well (audibly) when this kind of thing is performed.

Check measure 66 of Andante Cantible. 2nd Violin, Viola, and Cello change to pizzacato strings and return to their original instrument for the arco near the end of the piece.
Since 1998

All synths should play my first clip properly. I don't know of any that object to the 2nd.

The issue is discussed in Response to Program Changes here: www.midi.org/techspecs/gmguide2.pdf
See the 16th page of the document. It is called page 12.  <Image Link>

We have a couple of synths here, including two rather high end ones, that cough on the second clip where overlapping sounds using different instruments on the same MIDI channel occur. Specifically, there is an audible glitch or artifact in the performance of the second clip. The exact nature of the artifact seems to depend on the first and second instrument.

Note that the GM program change reference is on page 12.
