Well, after installing the 2.0.15 version UltraChannel could not work on my old Logic 5.30 (PC), whereas the previous version, it worked very well. Now I have an error message: "Error Code 193 was returned 'by ASIO Driver". Note that I have a pilot Asio4all V2 and that so far there was no problem. Equally, it also does with the old versio, 2.05. Someone of you have solution?
