I took a quick look at PreSonus Studio One, which included downloading the documentation, and I did not see any mention of music notation, so my best guess is that any "testing" of the Miroslav Philharmonik Solo Violin tremolo problem was done via MIDI . . .
PreSonus Studio One looks to be similar to MOTU Digital Performer (the DAW that I use on the Mac), and most of these types of applications are similar in one way or another, and some or all of them support MIDI . . .
Conceptually, I think that MIDI is interesting, but it is not something I have studied, although I am intrigued by the possibility of using MIDI to control a DigiTech Whammy pedal . . .
Nevertheless, it is useful to know that the Solo Violin tremolo problem occurs in at least a few DAW applications, separately from music notation . . .
As noted in my earlier reply, the definitive test for me on the Mac simply was to replace the Miroslav Philharmonik Solo Violin with the Solo Violin from the London Symphony Orchestra VSTi library (which comes with the full version of Notion 3), where the problem did
not occur with the LSO Solo Violin . . .
However, in examining the LSO Solo Violin, I noticed two things that I think are important:
(1) There is no separate VSTi user interface for the LSO instruments, which you can confirm (a) by single-clicking on the name of a Miroslav Philharmonik VSTi in the Notion 3 Mixer, at which time the standalone Miroslav Philharmonik VSTi user interface appears, but then (b) by single-clicking on the name of a LSO instrument in the Notion 3 Mixer, at which time nothing appears . . .
(2) There is no separate "tremolo" setting for the Solo Violin in the LSO VSTi, but there are quite a few "tremolo" settings for the Solo Violin in the Miroslav Philharmonik VSTi. Additionally, it is possible to adjust various parameters of an instrument via the Miroslav Philharmonik VSTi user interface . . .
When you consider (1) and (2) with respect to what actually is happening, I think that one can make an inference, which is focused on the high-level perspective and a bit of intuitive common sense . . .
Prior to this discussion, (a) I had never heard of "measured tremolo" and "unmeasured tremolo" and (b) I had never noticed the stroke marks in music notation, so it took about 15 to 30 minutes of surfing wikipedia to make sense of this, but so what . . .
So what! Being primarily a "play by ear" musician, I know a lot about tremolo and vibrato, and I understand the differences from the perspectives of mathematics and physics, as well as by virtue of being fascinated with the Fender two-point synchronized tremolo system of a Fender American Deluxe Stratocaster, which actually is a vibrato system, so while until very recently I had no idea how to specify this using music notation, playing vibrato on an electric guitar and knowing how it should be played on a violin (which I studied for a while as a youngster) was easy, as it is with singing (at least to the extent that a singer can do tremolo and vibrato, which usually are advanced techniques, although singing tremolo is a bit strange at best) . . .
From the perspective of intuitive common sense, this led to wondering
WHY it might make sense to put "measured tremolo" or "unmeasured tremolo" marks on the notes for an instrument that already was set to do tremolo . . .
So, I did a few more experiments, where I was able to confirm that the tremolo marks (from one to three strokes either on the stems of notes that have stems or above or below the notes that do not have stems) actually do something for the LSO VSti Solo Violin, where a single-stroke maps to slow tremolo; a double-stroke maps to medium tremolo; and a triple-stroke maps to fast tremolo, although it sounds more like what I call "vibrato" than what in the electromagnetic universe is called "tremolo" (which simply is a variation in volume over time, as contrasted to vibrato, which is a variation in pitch over time) . . .
There are differences in the Miroslav Philharmonic VSTi Solo Violin when it is set to tremolo and one then puts various strokes on the notes, but the differences are more subtle than what happens when LSO Solo Violin notes are marked with tremolo strokes, so the general concept of putting tremolo marks on an instrument which already is doing tremolo is a bit strange from my perspective, although mostly because tremolo marks on an instrument that already doing tremolo is considerably more subtle in this specific instance . . .
Explained another way, from the perspective of blending or mixing a set of instruments, using subtle effects on instruments tends only to blur the instruments rather than to reveal them, hence while the tremolo marks have a subtle affect on the Miroslav Philharmonik Solo Violin when it is set to do global tremolo, I am not certain what benefit this provides when there are other instruments . . .
For example, if the desired result is faster overall tremolo on the Solo Violin, then this can be adjusted via the Miroslav Philharmonik VSTi user interface, where it is done the way one sets a tremolo effects pedal for an electric guitar . . .
If the desired result is more intimately controlled tremolo on an individual note or a series of notes for a Solo Violin that is a featured or prominent solo instrument in a section of a song, then I think it makes more sense to use the LSO Solo Violin, which can be done with multiple "clones" and panned to different locations to make it more prominent in the mix, especially when the particular genre of a song is
Heavy Metal or one of its many variations, because by the time you add rapidly beating double-kick drums and a few baritone guitars playing power chords, hearing subtle differences in anything is nearly impossible no matter how skilled one might be in mixing . . .
And for reference, I added a few more measures to the "Ode To A Node" piece, which includes two "cloned" LSO Solo Violins (panned left and right, respectively), as well as one Miloslav Philharmonic Solo Violin with tremolo but no specific tremolo marks, which is fabulous . . .
