You've pretty much summed it up.On pretty much all fractal devices I've used (except the fm9), the purpose of the initial value setting is to ignore the resistance value reading on the connector on system boot up and preset changes, and continue to do so until the value changes.
Having a pedal connected or not, or the presence of a pull down resistor shouldn't change anything cuz that's a software function.
The issue here is that the fm9 does that correctly when changing presets but doesn't on boot up, unlike all other devices, and this has nothing to do with hardware design otherwise it wouldn't work on preset changes either.
Yup. This is what "pull" resistors have been doing for 100 years.Actually, I think the pull-down resistor has been put there to improve an issue that was present on the ax8 (and probably all hardware of the same gen), where the connection was left 'floating' when no pedal was connected and this caused tiny changes in the value read on the jack which triggered it to casually jump off the set initial value.
Can't be done. On a floating connection, a pull-up or pull-down resistor will pull the voltage up or down until it hits the power voltage or ground. There's no way around it.The pull-down resistor should just make the reading stable and avoid this issue, and be the equivalent of having a (non-moving) pedal connected.
