Hi, first, you should contact our support for questions like that the answer would be way faster...
Now for telematic, the error message is because there will be a len version of UVI Workstation at the beginning of next week and we made a new version of Telematic a few days ago that was using it. So just ignore the message, it will disappear with the next version. If it really bothers you a lot, i can send you another version with that fixed.
For Marchin, the drum mappings are a typo on the website... sorry for that, but it actually makes no sense as it is not a drumset. It has 8 toms 5 snares and 2 bass drums and there is no way to make that fit into a GM mapping or any other drum mapping. I will change that on the website right now.
Now the faders don't control Loudness, they control the three microphones for each element.
So select an element in the Element menu, and then move the faders around. Same thing applies to the Pitch.
For DrumTasteBrush, there is indeed a bug with the second tom... i will update it and notify you via email.
But the snare faders are working just fine...just put all faders to the minimum and move them up one by one and you will hear the change in tone. The fader problem on the Tom Low is related to the Mute problem.
