I have Sound Forge 9.0e build 441 which appears to be the last upgrade. Have used it for years. Is there a Sound Forge 10 I use it for key changes changing recordings to MP3s and for pitch changes. And for smoothing live recordings. Am I safe or is Sony going to stop supporting it? And if I have SF9 do I get any break on the cost if I have to upgrade? Any information would be appreciated. Thanks!
