Yes, or even better "Octave Designation System", and combo box content None, Traditional, SPN, MIDI 1, MIDI 2. The traditional system can be used without super- and subscripts like this: C2, C1, C, c, c1, c2 for the default SPN C0, C1, C2, C3, C4, C5. I can write a help page in English for confused users, if you like.

Yes, I saw that afterwards. Thanks.

OK, so why not call it Octave Naming or Octave Designation System, and use "Helmholtz 1", "Helmholtz 2" and so on, as options? There is also another system that looks like System 2 in the OnMusic Dictionary but uses Arabic numerals instead of the tiny lines; this is still, I believe, the most widely used system in middle and northern Europe.

I use QSynth with VMPK so Sostenuto should work, shouldn't it?

The three piano pedals Sustain, Sostenuto and Soft

You are welcome, Pedro, and many thanks for your work on VMPK which is a very handy application! I think "Sustain", "Sostenuto" and "Soft" ought to be translated, and put in the order the piano pedals have with Soft to the left, and Sustain to the right.
