while typing the last post i let the "hanging" sonar project sit there ... and surprise ... after what must have been 10+ minutes where it looked like it had crashed, it returned saying that K5 cannot find more than 1100+ samples (ok, samples reside on a different SSD on the 2nd DAW but inside the K5 lib it is using identical stuctures ... and the 1st Project oculd located everything ok)
anyway, now I could browse for the correct location and after a save the project again opens quickly ...
well, it's very interesting that it takes sooooooo long on an all SSD drives DAW for K5 to figure out some files are missing ... of course, any sort of progress bar or other indication that everything is "OK" but just takes forever is pure luxury ...
anyway, learned something here
ready to do the comping in X3 now
