I'm not sure if Sonar users use the Roland TTS-1 soft synth but I like lots of the GM sounds! I'm a big Roland fan anyway because I own a lot of Roland gear but the TTS-1 never seems to play the correct effect setting apon startup in Sonar! I always have to open up it's interface and twist or touch the gain nob for reverb then it plays the settings! Maybe the settings of the  effects should be recorded in Sonar as a control parameter? Just asking!
