I just picked up a Sub 37 a couple of days ago at a local authorized dealer. It is my first analog synth and I am really enjoying it, but I have a beginners question about the tuning of an analog synthesizer.
I noticed the user manual states, "NOTE: Since this is an analog synthesizer based on 1 volt-per octave scaling, the extreme high and low ranges of the keyboard may play notes that are not perfectly in tune."
So my question is what defines "extreme"? As I am not entirely sure if the tuning of mine is normal.
Using an Init Preset and ableton's tuner, I have documented the tuning of the instrument relative to itself.
A#1: (2.7ct) - (2.9ct)
B1: (1.5ct) - (1.6ct)
C2: (2.3ct) - (2.5ct)
C#2: (1.9ct) - (3.0ct) <-- (i wonder why this one is less stable than the others)
D2: (1.3) - (1.5)
D#2: (0.9) - (1.1)
E2: (1.2) - (1.4)
F2: (0.4) - (0.7)
F2#: (0.6) - (0.9)
G2: (1.1) - (1.3)
G#2: (0.5) - (0.6)
A2: (0.5) - (0.7)
A2#: (1.2) - (1.3)
B2: (0.3) - (0.5)
C3: (0.8 ) - (1.0)
C#3: (0.8 ) - (0.9)
D3: (0.0) - (0.1)
D#3: (0.9) - (1.1)
E3: (-0.1) - (0.0)
F3: (0.4) - (0.7)
F#3: (0.7) - (0.9)
From G3 up to C5 it was consistent in being around 0.4 cents to 0.8 cents.
Does the above look normal?
So is C2 supposed to be the "extreme" point that they mention in the manual?
