MOTM-650 MIDI to Control Voltage Converter and SCALA MTS

The MOTM-650 is a four channel MIDI to Control Voltage converter that
supports the MIDI Tuning Standard with nine programmable scales. It can be
used to drive any analog synthesizer with gate and 1 volt per octave control
voltage inputs, up to four channels simultaneously. Link here:
http://www.synthtech.com/motm650.html .

After trying unsuccessfully to load tuning scales into the MOTM-650, I got
some more information from Paul Schreiber of Synthesis Technology that scale
programs 0 and 1 are write protected.

I use SCALA for generating tunings under Windows. Link here:

SCALA supports the MIDI Tuning Standard (MTS), as does the MOTM-650, to
transfer tuning scales across MIDI in a standardized manner. As I found
out, SCALA supports only the MTS tuning scale program number 0 by default.
I have corresponded with the author of SCALA and he will add MTS program
number support. He will also add support for program names, as right now
SCALA is always written by default in the MTS packet.

It appears the MOTM-650 MTS support was tested using MAC programs, probably
Max Magic Microtuner /16tone/ or Li'l
Miss Scale Oven http://www.nonoctave.com/tuning/LilMissScaleOven/ . So MAC
users should be able to write their own 650 microtuning scales with current
software.

Manuel already updated SCALA to fix this issue. Thanks Manuel!

Scala version 2.22Y now supports MTS program and names. I tested it and it
worked fine.

Critical SCALA parameters to set for dumps:
SET SYNTHESIZER 107 --> Sets MIDI dumps to type MIDI Tuning Standard bulk
tuning dump, 3 byte)
(or use menu item Edit/Preferences/MIDI/Synthesizer Tuning Options
(SEND)/Model: 107 MIDI Tuning Standard bulk tuning dump, 3 byte)
SET DEVICE ID 0 --> Sets MTS Device ID, default is 0, MOTM-650 ID is 0
(or use menu item Edit/Preferences/MIDI/Synthesizer Tuning Options
(SEND)/Device ID: 0)
SET PRESET 2 (or number 2-11) --> Sets MTS program number, same as program
location in MOTM-650
(or use menu item Edit/Preferences/MIDI/Synthesizer Tuning Options
(SEND)/MTS Preset: 2-11)
SET DESCRIPTION (name up to sixteen characters, only first eight used by
MOTM-650)
(or use menu item Edit/Edit Scale/Description/name)

Gee, I wonder who the microtonal mac user of MOTM synths is.
