The Roland PCR-500 is favored for its superb key feel and useful controls like split and channel/patch selection, despite having sliders and knobs not always utilized.

The PCR-500 can be connected via 5-pin MIDI through a USB MIDI interface, although the control software may not be compatible.

Connecting the keyboard to a TV can prevent the display from shutting off, indicating unique power behavior with different outputs.

Setting the PCR-500 to "class compliant" mode allows it to work with Logic's automap on Mac, but proprietary mode might unlock additional features.

Latest Roland USB driver only supports up to Windows 8.1; Mac users can use it in class compliant mode for broader compatibility.

Users have successfully modified the Windows 8.1 driver to work on Windows 10 by editing a text file, allowing continued use of the PCR-500.

The class compliant mode enables the PCR-500 to function with DAW programs on Macs, but it does not support the PCR Editor program or firmware updates on these machines.

Edirol devices often face compatibility issues with modern operating systems, and reinstalling drivers can sometimes resolve connectivity problems.

The PCR-500 is noted for its channel aftertouch keybed, which remains functional even in second-hand models manufactured as early as March 2007.

Despite not being a standard USB MIDI device, the PCR-500 is appreciated for its robust performance and can be found at reasonable prices second-hand.

Owners mention switching the "Advanced Driver" setting to OFF enables class compliant mode, allowing the keyboard to work without drivers on any computer.

Disabling SYS10 in the keyboard's settings can resolve issues with the device turning off when connected via MIDI.
