What is MIDI?

How do you use the joystick?

The joystick is the main interface for playing musical notes. Each direction plays a note and you can play harder or softer depending on how fast you move the joystick. You can see our video here for joystick playing techniques. (link needed)

How do I switch CMPSR on?

There is a button underneath CMPSR, near the connection point for USB C. Press once to turn it on and the LED on the top of the instrument near the joystick will turn green. To turn off, press and hold until you feel 3 x vibrations. After the long, third vibration, remove your finger and the device will power off.

Which way up do I use CMPSR?

That is up to you. It was initially designed with the buttons at the top and joystick at the bottom but many people preferred buttons at the bottom and joystick at the top so this is now the standard setting. You can select any of the main compass points to orientate the instrument to suit your style.

Does CMPSR stand up on its own?

No, CMPSR has been designed as a portable hand-held or mounted instrument. The inner box that CMPSR ships in also turns into a handy desktop stand and avoids going to landfill, which is nice. So don’t throw it away and keep hold of it.

How do I set up the stand?

It depends on whether you are using the 1/ provided stand or 2/ RAM Mount.
1/Take all parts out of the box so you are left with just the foam and the cardboard outer layer. Fold the sides of the box flat and then follow the creases to fold each edge up into a triangle, giving you sideways support. Video here
2/ Firstly, screw the diamond base onto the underside of CMPSR. Then loosen the screw on the arm and place one end over the ball attached to the diamond base and the other end to the ball attached to the ToughClaw. Now, tighten slightly so the balls are not able to slide out. You can now use the two joints to get your CMPSR into a comfortable position and tighten the screw fully to prevent movement.

What is a haptic motor and why does CMPSR have one?
