Amaze0 and Amaze1 Quick info on calibration if needed:
 
If the calibration on the controller box is not matching your delay, you can adjust it. 
 
Set the red side of the delay for several repeats, with high delay level to see if the delays are in synch.
 
Use a metronome, or a song with a steady beat to calibrate it against.
Something in the 300mS range is best. 
 
If you have a metronome or something you can program, that makes it easier and more accurate. If you set a metronome to 120BPS that is 500mS. You can set the delay in MANUAL mode (preset 0) to 500mS and see if the delay needs to go faster or slower. 
 
Or you can use TAP TEMPO MODE and just tap along with a song to see if the
delay needs to go faster or slower. 
 
To calibrate:
 
1) Go to preset mode2 (hold down left button).
2) Press right button to step to Program 0 (manual delay time mode) 
3) Go to Edit Mode (hold down right button)
4) Basic setting is CVTUNE of 0 0[  0]  0  (zero all three delay times).
5) To change one of the three, move the right knob to select 300mS
6) Use the left knob to change the value. 
7) to make the delay slower, edit the 300mS value and make it higher, +5 works well.
8) To make the delay faster, make the 300mS value lower. 
9) 150mS and 450mS should be set to 0. 
10) After the value is set how you want it, tap the right switch to load it
11) When all three values are how you want them, hold the right switch to get back out of edit mode.
12) Check calibration again and start over if it still needs tweaking. 
 
 
Hope that helps!
