Several problems with tsi 3.5, urgent need of help!! - SOLVED!
I don’t know if this kind of linking is permitted, but I have gotten no response on my problem in the 3.5 tsi thread, and I’ve got a gig saturday I’d really like to have my VCI fixed by then! Please look at this post:
Thank you for reading!
Just read you original post. To me it looks like your ports are not set. Open Preferences, click Controller Mapping, select the VCI from the menu. Now set your in and out ports to Vestax.
Let us know if this does anything, Phil.
OMG thank you thank you thank you !!! 
Worked like a charm, in retrospect it seems fairly obvious that It had to scan all input ports before, hence the glitches. I have 4 inputs, which makes the scan 4 times faster now I guess. You, sir, have just made my day!
