I render with it all the time. How do I know that? Because the blue light on the sd2 blinks while the song is being rendered. I have to use the re-render button. I don't try to render to mp3 since I like to use db poweramp for a better sampling rate and quality. I have TTS in sonar, but I use the Ketron in it while working with the midi tracks if I don't finish the song in BIAB. I was just curious why the .wav button doesn't work the same as in the past.
