The manual for it is much better written than the SPD-S as well... for noobs to this technology it's going to make their life much easier
The biggest problems are:
1) the driver install routine doesn't complete properly. The driver installs so that I can access it via USB but the installer stops at the "Ready to install driver. Please use the USB cable to connect" etc etc and won't go any farther. Which means the controls mentioned in the manual which should be accessible via the Win7 Control Panel doesn't showing up.... At least it asks if I want to use the uninstall routine (which you don't if you wish to retain the driver) rather than just self uninstalling.
2) the Wave Manager software is buggy. It installs fine, but anything other than the main window shows up at an angle of about 2 o'clock on my laptop. The buttons work in these sub windows but it's impossible to use because the graphics are all askew. I contacted Roland UK about this but I have no idea how quick they are going to be with bug fixing and new updates (not very from my previous experiences though....lol)
The good points with the software is that drag and drop is gonna make adding samples via the Wave Manager extremely quick!!!
I'll hopefully add more to this as I start using it and getting my head around the nuances and I'm sure others will kick in with their 2 cents worth.
