Any HalionOne drum content triggers intermittantly. Sometimes one in twenty will sound, sometimes more, it depends on the patch.

Examples of VSTi's that work are any other Cubase plug, BFD, DFH, basically every other plug I've tried it with.

Like I've said, I've tried all possibilities re: settings. I know you probably hear that all the time, but in my case you can take it to the bank. I've installed the content on a seperate 7,200 RPM internal HDD just to eliminate seek problems and the like with no joy. I've gone through all of the MIDI Prefs one by one and in combination, also.

This is definately a HalionOne issue. Seeing as there is probably only one more update, I don't hold out much hope for it being fixed. When I hear a Yamaha subsidiary doesn't have a piece of gear and seems unwilling to go the extra step and get it, I have even less hope.

BTW, is Steinberg USA looking for a good tech support person? Can I tele-commute? I have a lot of experience at Cubase.net sorting problems and know the software pretty much inside out.
