Hello!
I am aware of using the transposition trick for simulating a second set of samples, say, for the second violin, for instance. However, I'm asking: Would you recommend to have the "Second Violin" use the transposed violin samples by default or just when there are unisono passages (thus, only when there is the possibility of phasing issues) between, in this case, Violins 1 and 2?
Plus, I reckon, the different tuning curves etc do not compensate phasing issues?
Thank you!

Hi Lukas.
IMHO, there's simply no benefit, because you still need to create a track (or a staff, if you work in notation) of its own to host the trick-transposed instrument.
Can't tell for «tuning curves etc» to avoid phasing, they are far beyond my understanding of using VSL 😃
Hope it helps.
Thanks for your reply.

I think we're talking past one another. Of course I need a second track - I want a second violon section after all. 😊
The question, in short is: Are there any disadvantages in setting my second violin section up as a transposed sample set all the way or are the transposed samples inferior to the unmodified ones, so that I should only switch to transposed samples in case of both violin sections playing unisono with the same articulation?
Maybe someone from the more technical/experienced side? 😊
Thank you!

Hello.
I will go for "standard transposition" instead of "occasional transposition" until told otherwise.
May I add the question, if phasing only occurs in situations of

May I add the question, if phasing only occurs in situations of
- unisono passages of the same articulation/sample set
- any passages of the same articulation/sample set

Since no one is replying, this non-expert will respond with what he thinks.
1. Phasing should only occur when the exact same sample is playing, i.e., same pitch, same articulation. The same articulation but in a different pitch should not phase. If someone who really knows their stuff feels otherwise, please correct me.
2. If you have MIRx or MIR Pro, the built-in modifications of the sample to achieve positioning should take care of most phasing issues. There are presets for Second Violin, or for Winds and Brass for multiple players, so you can just let the software take care of it.
3. If your only option is the transposition trick, then to me the easiest approach is what you suggest, to set up the whole track with the transpositions. There's enough to worry about in DAW orchestral work without the kind of detailed fiddling it would take to isolate the trick to certain passages within a track.
Just my opinion, and I only put it out there to give you some kind of response.
Hello, Aric.
Using the same samples at the same time can lead to so-called phasing problems, when using two instances of the same instrument. (I'm still waiting for some of the specialists here to comment on when exactly they occur to what extent (see my post above).)
To circumvent them, one can send MIDI data transposed by one half-tone to VI (or whole-tone for the special edition; it is sampled in whole-steps) and then, inside VI, use the pitch bend in the opposite direction to "retune" them to the original (wanted) pitch. That way, another sample is used, and there are no phasing issues.
It is preferable to transpose up and pitch down (because otherwise the vibrato gets sped up) - at least this is what is recommended, as I recall.
In short: We want to hear C!
DAW: D ---to VI instance---> VI [uses D sample]: pitch down a whole step ---to DAW---> sounding C (but which is actually a D sample)
Ideally you would include a MIDI remapping tool in your signal chain (we still wanna hear C):
DAW: C ---transpose MIDI signal up a whole step when sending to VI instance ---> contine as above
The modification is just to ease the workflow, so you can enter the wanted pitches, without having to think about the transposition.
Bendings larger than a whole step are, I think, not recommended, so with the SE this trick will provide two additional "phasing free instances" of an instrument, whereas standard instruments will give you up to four (same proceedings but with half-steps).

Hello,
after more investigation it struck me that phasing is actually nothing more than (destructive) interference of superpositioned audio-signals. If I sum two identical audio signals with a relative phase of pi (or 180°) they cancel each other out. I always thought there was more to it...
Thus, I come to the conclusion that a "transposition-tricked" instrument is only necessary when stacking patches (or playing "unprocessed" unisono lines) of the same instrument. Any combination of the same instrument (same samples) which underwent individual treatment like panning or (different) MIRx settings (in my case) should therefore not cause any "phasy trouble" - can anyone confirm that? And correct any faults in my argumentation if necessary? (don't hesitate to use technical terms...)
A big thank you and good night.
Lukas
Thanks Lukas for this thread. I am no sound engineer and it was very helpful to read your posts. Thanks,

Simple panning won't help a lot, you will still hear phasing and cancellation issues. What will help indeed are processings like VI Pro's Humanize feature (which adds variation to pitch and timing) and the timbre-related changes induced by the MIR engine (due to the use of different, position- and rotation-dependent impulse responses as well as different pre-EQ settings used for Character and MIRx).
HTH,

Hi! Sorry for the late reply.
Yeah, after thinking about it again, panning makes no difference since it just "distributes" the same audio signal differently over the outputs at different volumes... Also, every constant shift of phase might also lead to effective cancellation. At least that's what one can easily try in every DAW by duplicating a track and nudging it against the other.
Can I conclude that, to avoid phasing issues, both (in the extreme case) similar audiosignals have to be processed differently in such a way that it's not just a constant shift in phase? So by EQing, different reverberation, pitch alterations, different timings... anything that would probably minimize the correlation between the former same signals? (I guess, different reverberation alone won't do the trick?)
Kind regards,
Lukas
PS.: It just came to me that we havent covered the main question of this thread... So, default transposition trick for Violin(s) 2, yes or no? 😄 (For now it seems, it's not necessary? Would there be a disadvantage to still just doing it?)
I would be really glad about a definite answer to the main question of the thread, namely "Should I transposition-trick an 'Instrument 2' track as a whole or just for problematic unisono passages with the 'Instrument 1'?" It is actually very close to the question "Will there be disadvantages to transposition tricking that suggest not to do it for the whole track?" (I'm aware that pitching down is generally better than pitching up due to vibrato speed.) I'm using the special editions.
I'm asking again, because I'm about to make some changes in my template.
Thanks!
Lukas
