Got my Hermod+ … no time on the weekend, but testing today, very nice so far.
However I was surprised that output CV calibration was relatively far off - I had the impression things were very slightly out of tune (with a digital VCO, so no temperature drift).
So I started the calibration procedure to verify the output voltages. All 8 voices needed substantial calibration, voltage was sometimes nearly 0.02 Volts off, which is about a quarter tone … but not consistently, some voices and some voltages needed more, some less adjustment.
I have a calibrated Voltmeter (BM 859s) with 5 significant digits and < 0.02% error, so precision should be fine for calibration.
Is each Hermod+ individually calibrated in the factory and I simply had bad luck or is the initial calibration necessary and expected?
Any recommendations if and how long the module should “warm up” before performing the calibration procedure?
