I just saw this posted in the announcement regarding the last release.  Quote:  “The TTS-1 synth is no longer installed by Cakewalk, by request from Roland. This product is no longer supported and has reached end of life. Older installed versions may continue to work but it is no longer a default for insert instrument.” Unquote    But I would imagine we will still have access to it if it was already installed. I guess it will not be installed with upcoming Sonar.  I wonder
