I made mention of the same thing in one of my first posts. In this day and age, dealing with 4k deisplays, UI scaling is a must (Im talking to you also Kontakt!). Im tempted to break out my telescope and place it between myself and the 50 inch 4k screen Im currently using just so I can read the text.
Also, yes, Im not purchasing anything more from Vienna until I hear some news on Vienna Instruments (not Synchron). I do not like the direction Vienna has taken with Synchron seemingly taking center stage while the main reason I bought into Vienna in the first place was the design philosophy behind the VI line. Since Synchron takes the opposing approach that every other library on the market has taken ("preverb" or non-dry samples, a bubbly and quite frankly ugly UI that is very reminiscent of what you might find on a childs toy), I feel like I might have bought in to the wrong library. The two main reasons I started with Vienna is, the UI in VI is perfect. Its informative, easy to use, and the matrix idea clicked with me, and of course, the dry samples.
For now, the special edition complete is serving me fine for mockups, and Im using the complete Orchestral Tools Berlin Series for my final phase, since they are almost identical in volume and velocity layers to the special edition (Orchestral Tools just has more layers). I dont make any money from this stuff, its a hobby, and that is something that concerns me about Vienna, its very expensive, and by splitting their user base like this, it leaves many unsure about what to do.
Ideally, Synchron and VI should be cross compatible. Use Synchron Player if that suits you, use VI if that suits you, the libraries should load in either player.
