Ah - I see. You’re that type of engineer. We deal with them fairly regularly at work. It’s difficult to make them understand a lot of things that aren’t working. They say: “It should work...” We say: “It doesn’t...” Then much time is wasted getting the simple reality of the situation into their heads. But that’s OK, because some company pays us for the time. These engineers keep themselves employed making things take a lot longer than they should. Your contention that “ - it’s just a DSP chip - it can be programmed to do anything - “ is a key error here, and going on to base much of your reasoning on that is the problem. Reminds me of a recent job on the underground pipe of a town water supply that had to be postponed for a couple of months. A section with a fancy new flow meter and assorted sensors was designed and had to be built then shipped from overseas. It was to be inserted in a cut out section of the existing pipe. Too bad it was the wrong size. |

Yamaha’s tone generator chips are not fully flexible DSPa. They are rather an ASIC which only does very specific AWM2 synthesis and FX processing. This way Yamaha can curtail software development costs by programming a dedicated DSP which does much of the synthesis work in hardware. Look for E-mu 8000 or AMD InterWave programming references if you need a glimpse at actual design of dedicated tone generator chips. BTW, all keyboards that were based on general-purpose fully programmable DSPs either failed on the marketplace or didn’t even make it to the market. The original Korg OASYS concept (not the 2005 software-only model, but a 1996 keyboard and 1999 PCI card which were made with half dozen DSPs), the Alesis Fusion HD, and the Yamaha VP1 and VL1 synths which were researched in cooperation with Stanford. The Korg OASYS keyboard and Yamaha VP1 never made it to full-scale production, the Korg OASYS PCI, the Yamaha VL1, and the Alesis Fusion were discontinued very shortly. I see a peculiar pattern here. |

I don’t know to what extent that the chips are programmable or not. I just remember that the Kurzweil added lots of new features (KB3 mode, VA) as a software upgrade using the original (k2500) hardware. I don’t know what chip was in the Kurz and I don’t know what chip is in the Yamaha, really. I would find it hard to believe that NOTHING can be added to the featureset with a software update, but anything is possible I suppose. I never claimed to be a hardware engineer. Whether the DSP is programmable or not, the OS is certainly programmable. Of course it’s heretical for me to say that and now this will beget another round of personal attacks based on “I’m that kind of engineer” for “being stupid enough to think that the OS is programmable” or something.
