If if runs on Windows CE, it is off on the wrong foot. I have heard good about that platform.

Does anyone who was there have any comments about it? I talked with Dave Carpenter, the inventor of the Veritune, and this is what I gather is up with Veritune. The main feature is the method of taking inharmonicity measurements on the fly while tuning. The user does not have to do anything explicitly to take inharmonicity readings. Veritune is supposed to be able to evaluate the sound and tell when the readings are good and when they are not. You begin tuning at A440, I guess, and then as you tune each note, Veritune refines its tuning curve based on the inharmonicity reading that it gets while you were tuning the note. One drawback that I see is that your tuning curve is constantly being modified as you go, which may invalidate some of the earlier notes that you tuned. However, Dave maintains that after the first few notes are tuned, the subsequent revisions to the tuning curve based on later inharmonicity readings are inconsequential. And there did seem to be a control on the screen for locking or unlocking the tuning curve. I suppose that if you lock the tuning curve you freeze its current state so that subsequent automatic inharmonicity measurements do not modify the tuning. The device is stand-alone (not a program in a laptop) and it is supposed to have a battery life of 15 hours on one charging. The device software runs on top of Windows CE and has a display screen that contains two concentric circular patterns that indicate coarse and fine tuning error. It has memory for storing tuning curves by name. The prototype at the show was somewhat flakely, but that was not the actual circuit board that will be used in the real product. I would not draw any conclusions from that glitch. Let's see what this device does when it gets into its eventual form and when it is applied to a wide variety of pianos. -Robert Scott Real-Time Specialties
