On Kurisu's post about the SS3.4 download it says: Today I introduce to you Sonicstage 3.4 - the full version, with Simple Burner 2, and a few other bug fixes recognized by the community to deliver the best possible Sonicstage experience. Throw this on a Hi-MD disc, usb thumbdrive, etc. and you can now use Sonicstage anywhere, anytime. Does this mean that then SS can be used on a host computer without installation? How would that work? Connect my RH910 to one usb port and the thumb drive to the other? Thank you for putting this download on the forum - it was exactly what I needed as the recorder came with 3.0. It worked like a charm once I got access to an appropriate computer.
