I'm looking to get one of these with a view to controlling it via a TSU9400 and RFX9600 (RS232) and I wondered if anyone else had tried it? The YSP-4100 is quite new but I expect it will use existing Yamaha codes?? I'm aiming to be able to have "bookmarks" for volume settings and perhaps "real-time" feedback of the volume level?

Is this going to be possible - I realise there will the usual potential issues with the RS232 processing within the RFX9600 that I hope careful programming will sidestep (buffering etc) but I'm more concerned about the Yamaha code support.
