That's right.

That's right.

I don't know about Rosegarden very well and I don't know how it works
in detail. Perhaps, the midi data (file.mid) may contain the message
such as GM System On. If so, MTS features will be initialized.
To make it simplified, Here I will introduce another approach which
uses ASeqView, VKeybd and Pmidi. The latest ASeqView (aseqview-0.2.8)
can visualize the tuning control events. It can also output the
received events to subscription ports with tuning control events such
as temperament tonalities and types from a MIDI keyboard via Tuning-
control Port. For example:
$ timidity -iA -B2,9 -q0/0 --sequencer-ports=1 -EFresamp=1 &
...
Requested buffer size 4096, fragment size 2048
ALSA pcm 'default' set buffer size 4096, period size 1364 bytes
TiMidity starting in ALSA server mode
Opening sequencer port: 128:0
$ vkeybd & # sequencer port: 129:0
...
$ aseqview -d128:0 -T129:0 &
...
Requested buffer size 4096, fragment size 2048
ALSA pcm 'default' set buffer size 4096, period size 1364 bytes
$ aconnect -li
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 62: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 129: 'Virtual Keyboard' [type=user]
0 'Virtual Keyboard'

$ aconnect -lo
client 62: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 128: 'TiMidity' [type=user]
0 'TiMidity port 0 '
Connected From: 130:0
client 130: 'MIDI Viewer' [type=user]
0 'Viewer Port 0 '
Connecting To: 128:0

$ export ALSA_OUTPUT_PORTS=130:0
$ pmidi file.mid
[Quick Reference for Tuning-control Operations]
Piano Keyboard: just hit key: sets the key in I, V, IV, etc.
keep press key: sets the key in VI, III, II, etc.
Sustain Control: OFF (0-63): makes it major
ON (64-127): makes it minor
Program Change: 0 (Piano 1): equal temperament
1 (Piano 2): Pythagoras tuning
2 (Piano 3): mean-tone tuning
3 (Honky Tonk): pure intonation
64 (Soprano Sax): user-defined temperament #0
65 (Alto Sax): user-defined temperament #1
66 (Tenor Sax): user-defined temperament #2
67 (Baritone Sax): user-defined temperament #3
I hope this information will help you.

Yes, I want your MIDI file. :-)
