Oscitron / pitch calibration question
« on: February 26, 2017, 09:55:53 PM »
I'm having trouble calibrating the 1v/oct input. It did not appear to hold the right pitch (A4) when I was trying to tune it with a MIDI note, so I attempted to calibrate it using the instructions in the manual. I'm very confused about the instructions, though, and I doubt I'm doing this right. I understand where the value dial needs to be for D#2 and A4, but what about the function dial? should it be in coarse or range mode when I begin pressing it in to calibrate the device? Should I have it in coarse mode for D#2, with the value dial on 0, and then put it in range mode for A4 with the value dial on 1?

Also, I'm not quite clear on the act of calibrating it. From the manual, "Then press and hold the Function knob until it flashes, whilst holding the value knob," what does "whilst holding the value knob" mean? Does it mean that I should press and hold it as well?

I've tried doing this correctly, but I end up with a different calibration than what the manual says should happen: "When course = 9, fine = 0, range = red, etc...the output will be A4 - 440Hz." Well, for me the output was about 890Hz. When I moved coarse to 6, the output was closer to 440, but it was actually quite sharp, and I had no way to fine tune it down because the fine knob was at 0 already.

So I'm concerned about the process for calibrating, and I'm a little concerned that even if I do the process right, the oscitron will still be pitched too sharp.

If anyone could help me with this (please Paul!), that would be awesome. Thanks.
