Hi everyone!

I have a question 'cause I' don't know why, but when I open a virus VST track into the instrument track is all good,if I open another instrument track and I want to put another virus VST,appear me a window that speak me "You must to connect your virus" and doesn't open the VST...but in the other instrument track is all good...really I don't know...

thanks for the answers.

PS,VST is for use an universal language,I know is an RTAS, anyway thanks for the correction
