Pre-Question-Introduction: I am a noob, but I really want to understand what exactly is going on behind every single dial and button I press.
The "Uni" button on the Analog module of Ableton live, which stands for "Unison," creates a second voice. The pitch of that additional voice depends on the value of "detune."
I'm trying to understand what exactly this means. To do so I am starting with the most simple inputs as possible. These questions assume one sine wave oscillator, and an amp at a constant 100%
- The value of Detune ranges from 0 to 100; what are the units here? What is 0 and what is 100?
- Using a sine wave and 2 voices creates a rhythmic silence and pause which is more noticeable for smaller values of detune. Am I correct that this is a manifestation of beat frequency? Can I control this effect or is that pulse just a fact of life?
- I am able to increase the number of voices from 2 to 4. What is actually happening here, what determines the pitch of those four voices?
- I noticed that the effect of Uni changes depending on when I enable it (try spamming a note and rapidly turning uni, with detune set to 0, on and off). It seems the phase of the second voice can shift around resulting in different types of interference. What determines the phase of the second voice in relation to the first? Is there a way to predictively enable it?
Thanks for helping a control freak understand the tool.
