I’m not professional programmer and sorry for my english,
but I had same problem.
What I understand by looking around in the forums is that the VST3 standard - for STUPID reason arrive at MIDIOUT - has been limited. In practice, only the NOTE-ON / OFF and some others (I checked the NRPN, strangely also the CC11 goes into my project… it working good in VST2).
I recommend this post:
The reason that many audio programmers have not joined VST3 for many years and STEINBERG’s recent decision to inhibit the distribution of VST2 makes it clear how completely this company has moved away from MUSICIANS (I am a professional and live in concerts and I know what am I talking about) and they has come to its “creative death”.
In my opinion - seeing their latest software productions - I noticed how much they tend to favor their choices by imposing them on musicians (for example the instrumental “articulations”, the audio tracks connected to a single instrument, the clumsiness of the interfaces, etc … ).
They do not realize, however, that they have directed their focus to AMATEURS.
A professional musician never looks for
but looks for “personalizations”
and they dont like “limits”.
At the end a starting point for reflection (sorry for long post)…
Can a KEYBOARDS PLAYER program a drum track in “artistically” way?
No!. He pay for drummer if want a professional drums track.
Only amateurs do these things…
but STEINBERG still doesn’t understand it.
