That's right, we don't have much control over MIDI playback. That said,
we did have to write a fair bit of code for parsing MIDI files in order
to rip the lyrics and timing info out, so we may be able to leverage
some of that.
Since in the "long run" we have plans (at least, I do ;) to roll our own MP3/OGG/WAV/stream player so we can have fun things like seeking, pitch shifting, etc.,, we could always leverage some of that for some kind of lower-level poking of Timidity; at least theoretically :)

I'm in a similar position at the moment but if anyone is interested in
having a stab at it, I'd be happy to incorporate it in PyKaraoke,
provide support etc.
Same here! I'm rolling through four (!) paid projects right now with two more chomping at the bit to get started, yet I still want to bang away on this thing, too. I still want to add some spiffy things (like the afore-mentioned pitch-shifting and seeking, along with a time display (minutes:seconds, that kind of thing, like a standalone player), more keyboard controls, etc.
BTW, I tested the C-optimized version of the player (v0.5) -- holy CRAP that thing's fast! Woot! Seriously fast :)

Great. By the way, I forgot to give you the URL for Will's
pitch-shifting FAQ:
http://willfe.com/index.php/Pitch-shifting_With_PyKaraoke_and_JACK_HOWTO
Yay! My name up in lights ;)
By the way, the pitch-shifting module I've found for Jack isn't incredibly high-quality; it sounds okay but pretty "tinny" when it's done. I think maybe chaining some kind of filter *after* pitch-shifting to smooth out the sound might help, but I haven't yet experimented with that.
