MPC Key 37 is connected to the computer but displays "Looking for computer" in controller mode

"Looking for computer" is the message that automatically comes up when the MPC is put into controller mode. The MPC will stay on "Looking For Computer" until it detects the MPC Desktop Software is running on your computer. However, it will not detect the software if there is no driver installed and the software is not on the same version as the firmware of the MPC Key 37. If you plugged your MPC into your computer and it is still saying "Looking for computer", please check the following.

  • The MPC Desktop software is on the same version as your MPC Key 37's firmware version.
  • The MPC Key 37 driver has been installed.
  • The MPC Desktop software is running.

If you have confirmed all of three of the above and the MPC still says looking for computer, please refer to 

the 'MPC Key 37 is not recognized by my computer' section below.

If you have confirmed that your MPC software and firmware versions are the same and that your drivers are installed correctly, there are still troubleshooting steps that can be performed! At its core, the MPC Key 37 is a MIDI controller. 

Potential causes for connection issues are:

  • A bad USB cable or port
  • Poor communication, typically due to the use of a USB hub, long or extended USB cables, or having too many USB devices plugged in.

The first steps when you encounter a device not connecting properly should always be to try different USB cables, different USB ports, and even a different computer. You will also want to disconnect other USB peripherals and avoid USB hubs. 

We have several troubleshooting guides for MIDI controllers, which are linked below!

MPC Key 37 is lagging or freezing during use  

The MPC Key 37 boasts some of the most powerful and complex tools ever included with an MPC, which may require a significant amount of system resources. Therefore, it is crucial to monitor your System Resources when creating on the MPC Key 37 in standalone mode. This will provide valuable insight into any potential issues that may cause your unit to slow down during use. Should you encounter lag or freezing on your unit, we recommend navigating to the System Resources panel of your MPC by clicking either the battery or system resource bars available from the Main Mode menu. This will bring up a screen resembling the one below.

The indicators in this window show current usage statistics:

  • Battery: If you are using MPC Live or Live II powered by its internal battery, the first indicator shows the current battery life as a percentage. (See Battery Usage to learn more about MPC Live and MPC Live II’s internal battery.)
  • CPU: The CPU indicator shows the current CPU as a percentage. If this indicator shows that you are nearing full capacity, you may begin to experience some freezing. Try disabling any unnecessary plugins or effects when not using those tracks! 
  • RAM Usage: The Mem indicator shows your MPC hardware’s current RAM usage.
  • Drives: The Drives indicator shows the available storage space on any detected external storage devices or the internal drive of MPC X, MPC Live, MPC Live II, or MPC One.

If these resources all check out, there may be something else causing your unit to experience lag. Refer to the guide below for a more in-depth look into why your device may be freezing!
