Turntable sensitivity explained

1:1 means the rotary encoder counts from 0 and up to (but not including) 256. This value is directly reported as the joystick X-axis.

1:N increases the range in which the encoder counts up to at the hardware level. 1:2 means 0 to 512, 1:4 means 0 to 1024, etc. In other words, you are setting finer granularity for each tick as N increases. Effectively, going from 1:2 to 1:4 makes so that twice the amount of rotation of the encoder is required to input a full rotation.

N:1 means the rotary encoder counts from 0 and up to (but not including) 256, but the value reported to your computer will be amplified by a factor of N. 4:1 means it will move 4x as much, and so on. This comes at a loss of granularity (values will "jump" between each tick).

For DAO turntables, it is recommended that you stick to values between 1:2 and 1:5, inclusive. 1:2 is super sensitive, 1:3 is sensitive, 1:4 and 1:5 are like stock DAO.
