I don't think so. However it could be a throughput limitation problem in the Studio 4. Some MIDI interfaces don't allow full speed MIDI throughput in both directions simultaneously. The loopback test feature in SoundDiver 3.0 however tests this academic case. SoundDiver 3.0.1 will no more do this, as it shows problems in the MIDI interface which don't hurt in real life. -- Beste Gruesse - best regards, Michael Haydn EMAGIC Soft- und Hardware GmbH SoundDiver Group Executive Logic Windows Developer Unitor8 Control Project Manager
