By default, the User inputs in Dewesoft will jump to the next value within one sample like shown in the picture below but sometimes a slower transition is required. 

The slower transition can be achieved with the use of Dewesoft mathematics. Here is a formula that adds or subtracts the value from the current value, until the value of the formula is equal to the one of the user input. 

Speed_SP: This is a channel with a final value of our formula 

Speed_ramp_rate: This is a rate with which you will get to Speed_SP

Attached is also an example setup file.
