I've used PT for 12 yrs. Mostly singing along with midi music using sound fonts. My old Win 2000 PC works fine with Sound Blaster Live mp3 card. TC Helicon vocal stability and added harmony works really well.

I'm now starting to use my newer Win Vista PC with newly purchased PT 2017. Everything seems to work well except for TC Helicon. Vocal quality is good but, when I apply the TC Helicon vocal pitch correction the voice sounds like some weird cartoon voice. I've been using the tc helicon for many years with no problem,[/i][i][u][/u] I've tried the built in audio as well as my external S Blaster Audigy 2NX. No change.

Any thoughts, Thx, Bill
