I have a story to help 
multistepper.h library Can you use 4 stepper motors?
Yes. The problem is in the code you didn't post.
MorganS:
Yes. The problem is in the code you didn't post.
Here’s the complete source code

My problem
// Create instances for MultiStepper - Adding the 3 steppers to the StepperControl instance for multi control
StepperControl.addStepper(stepper1);
StepperControl.addStepper(stepper2);
StepperControl.addStepper(stepper3);
StepperControl.addStepper(stepper4);
When adding "StepperControl.addStepper(stepper4)" When I press the button InOutSet. code "switch (InandOut) {" inoperative
But everything else works? Just that one button? Did you check the wiring?
