This still seems to be disabled for the .mptm format when using any tuning other than 12-TET, even in the latest version of mptm. So, as of now, if I want to make a song in micro-tonal, I lose the ability to do perhaps the two most important effect commands.
--------------------------------------------------------------
Couldn't you or any of the other programmers simply
1) Program vibrato to work the same way as in 12TET IE same depth&speed possibilities and parameters
2) (G00-type) tone-portamento to
A) Merge toward a higher/lower note at the same rate as with 12TET but
B) Stop when the desired micro-tone is reached instead of desired named tone (IE 12TET note)?
3) It would be "ok" if you ignored fixing the pitch filters for now...they are seldom used. Also I understand if you must ignore to portamento up/down commands since it's nearly impossible to do well considering frequency gaps between notes may change drastically from note to note in a micro-tonal scale.
Ultimately the human ear is still going to see porta-mentos the same way between "weird" scales and 12TET, the only difference is which frequencies the porta-mento starts/stops at...
On the surface it seems the portamento algorithm could be as simple as modifying the 12-tone portamento to match itself against a start/stop list of all the notes of a given "special" scale rather than matching its start/stop points against 12-TET.
Interesting thread, but what's 12TET in the first place ?

Check that the value of 'finetune steps' is greater than zero for the tuning you're using. For information how the portamentos etc. are currently implemented with custom tunings, see http://forum.openmpt.org/index.php?msg=12210.0&highlight=#12210
