## Detailed Description

template<uint8_t NumBanks, class BankAddress, class Sender>
class Bankable::SmartMIDIFilteredAnalog< NumBanks, BankAddress, Sender >

A class for potentiometers and faders that send MIDI events.

When changing banks, it disables the potentiometer until you move it to the position where it was last time the current bank was active. This prevents the values changing when changing banks.

## ◆ State

 enum State

State of the smart potentiometer.

Enumerator
Active

The potentiometer is active, the position changes will be sent over MIDI.

Lower

The value of the potentiometer is lower than the previously recorded value for the current bank.

In order to activate the potentiometer, you have to move it up.

Higher

The value of the potentiometer is higher than the previously recorded value for the current bank.

In order to activate the potentiometer, you have to move it down.
