Hi, i believe i have a chicken and egg issue here… i have created a pvx file using pvanal. The output is: analysing 35280 sample frames (0.8 secs) from timepoint 1.0 frameSize=1024 1024 infrsize, 256 infrInc 135 output frames estimated pvanal: creating pvocex file 20 40 60 80 100 120 140 160 Now i want to use this pvx file as a mask in an instrument, and i have to put it in a table. But i do not know the table size, and deferred size is not allowed. How can i get to know the table size of the pvx file? filelen — Returns the length of a sound file! but not a pvx file ftlen - deferred size for GENs 1, 2, 23, 28 or 49 only, so GEN 43 is not one of them tableng - same thing as ftlen
