another possible option, changing pitch-bend

Jay here,
If your synth or sound card conforms to the Roland gs "standard", and if you
can access controller messages then:
at the start of the sequence and on each channel you first, assign the
number "0" to controllers 101 (rpn-msb) and 100 (rpn-lsb.) Then, assign a
number from 1 to 24 to Controller 6 (data entry.) That last number defines
the number of pitches , the default being two semitones from one end to
t'other. You can insert all three messages at the same start-time.
In addition, you can tune the whole synth so you have your choice of "early
music" pitches. for coarse tuning:
CC 101--0, cc100--2, cc6-- 40 to 88. 64 is the default, nubers on either
change the pitch by one semitone.
For fine tuning:
cc101--0 cc100--1 cc 6--14 to 124. 64 yields A 440, increments change the
pitch by approx 1.5 cents.

(I sent this yesterday and it seemed to be eaten; if it appears
twice, my apologies...)

Just a couple of clarifications. I don't know the Roland GS standard
intimately, but I believe it is an extension of General Midi. In the
case of the controllers you reference, this is part of GM as well as
its superset, GS.

The default is +/- 2 semitones, so "from one end to t'other" is twice
that, or 4 semitones.

The controllers you reference in decimal are the same as those I ref
in hex in TD 318.3 (B0 65 00 and B0 64 00). Thanks for adding mention
of coarse and fine tuning. They, of course, will not affect the
relative tuning achived by pitch bends.
