Thank you!
No, there’s no problem with addressing the Major chord with CV.
Actually there’s no problem at all, and no need to change anything. I just had the feeling since some time that my use of your modulation ports is off. What I meant with my guess of a “2 Volt range” (upon closer look it’s even only about 1.4 Volt) is the following:
- If I set the Structure knob to noon, the attenuverter to 100%, and send -0.7 Volt to the CV port I get the Octave chord (corresponding to fully counterclockwise knob position without CV). Everything < -0.7 V (down to -5 V or even lower) is still the Octave chord.
- If I send +0.7 Volt I get the Major chord (corresponding to fully clockwise knob position without CV). Everything > +0.7 V (up to +5 V or even higher) is still the Major chord.
- I observe the same, for instance, for Brightness: If the knob is at noon and the attenuverter is 100%, below -0.7 V and above +0.7 V the brightness doesn’t seem to change anymore.
I probably have a misunderstanding about the meaning of “the CV port range is -5V to +5V”: I always understand this as “-5V corresponds to fully counterclockwise knob position, and +5V is fully clockwise” (if the attenuverter is maxed). If I want to cover the full range with an LFO, for example, I use a bipolar LFO with -5/+5 Volt range. Let’s say, it’s a triangle wave with a fixed slow frequency, my expectation was always that the result is the same as if I’d move the knob steadily by hand from left to right and back.
But if I apply the -5/+5 Volt LFO, for example, to the Brightness port with the attenuverter at 100%, I would get the minimal brightness for a long time (-5 to -0.7 V), maximum brightness for the same long time (+0.7 to +5 V), and then in a comparably short period (-0.7 to +0.7 V) the brightness will actually change.
No problem, because there’s the attenuverter! By trial and error (using again the Disastrous Peace Structure and Brightness inputs) I found that I have to set the attenuverter to about 38% to get the described behaviour with a -5/+5 Volt bipolar LFO. So, with 38%, -5V input corresponds indeed to counterclockwise, +5V input to clockwise knob position. (I was assuming first, 14% (= 0.7 V / 5.0 V) should be the right attenuverter position, but testing showed, it’s too small. I guess, something with the attenuation is not as linear as I was assuming…)
Holy cow, what am I nitpicking here.
Like I said, no need to change anything, it’s just different than I expected. Best is, forget everything what I wrote!
For now, as my working hypothesis, I’m happy to keep 38% as the magical Sanguine attenuation number in mind (but subject to be verified on a case by case basis)!
