Tapping the aux/foot switch enters a global BPM. the buttons perform set math to the master bpm in ms. Knob1 controls left channel feedback rate and knob2 the right’s. Knob3 controls the wet/dry. Knob4 controls the amount of stereo mix, all the way to the left is ‘hard-pan’ and all the way to the right is ‘stereo’.

You can customize the math for the buttons just by changing the numbers in the message boxes.
