Steve has always been very helpful, and fairly accessible as well.
Even he couldn't help with a glaring bug on the PSR2000, which they never corrected.
In the vocal harmony section, the Karaoke Girl setting was wrong. It worked correctly on all the predecessors, but on the 2000 it wouldn't take out the lead voice, and it took extensive workaround editing to get it even close tow orking right. Steve did come up with a workaround, but Yamaha refused to acknowledge that it wasn't right, even though it was right on everything before it everything after it. It just wasn't important enough to them to fix it. I believe at the time, even though the 2000 was advertised as having the OS in software, it actually required a hardware fix to upgrade the OS.
Just remembering that there were always glitches from every manufacturer.
