I followed Graham's advice to check into my MIDI player and found that Timidity has a huge array of command-line options. I tried disabling reverb and it helped a bit. Hard to say. It sounded like it still had some reverb but it wasn't nearly as bad. I'm not even completely sure I specified the options/arguments correctly. There were no examples in the manpage (argh!! I hate that!!), and it was hard to say exactly how to do it, since the disable reverb option was nested inside another option that apparently didn't need a hyphen and...(sigh...)

It's not in the docs because it's not lilypond.  Consult the docs
for your MIDI player and/or synth.

LilyPond is for typesetting but it also has MIDI capabilities.
LilyPond's typesetting capabilities are expanded by Scheme and even
native PostScript markups.
In a similar way, MIDI capabilities could well be expanded to allow
arbitrary MIDI data to be output. Otherwise, all the effort in
instrument equalizing, sound selection etc, stays in a very limited

For reverb, with a bit of luck it would suffice to send reverb type
and time events specified in General MIDI level 2 that fall into the
Universal System Exclusive type of messages (I've not tested it).

for example
F0 7F <device ID> 04 05 01 01 01 01 01 [pp vv] ... F7
where pp = 0 : reveb type; pp = 1: reverb time, and vv is the parameter value.

Please correct me if I'm wrong.  Almost surey there is an easier way.
