Some users initially mistook the PCR-500 for having polyphonic aftertouch due to misleading marketing, but confirmed it only supports channel aftertouch through testing MIDI events.

Owners appreciate the merging capability of the MIDI Thru function, despite the active sensing MIDI messages that cannot be disabled.

Owners suggest using standard MIDI ports with a USB MIDI interface, like the ESI Midimate EX, for reliable connectivity across different operating systems.

Although it lacks true polyphonic aftertouch, the PCR-500 is praised for its use with mono synths and for performing dynamic pressure modulation on chord synth pads.

The PCR-500 is favored for its superb keyboard feel and minimalistic controls, making it ideal for users focusing on key performance rather than additional features.

In class-compliant mode, the PCR-500 functions with DAW programs but loses compatibility with the PCR Editor and firmware updates.

Users have successfully modified the Win 8.1 driver for the PCR-500 to function on Windows 10, involving minor edits to a text file.

In class-compliant mode, aftertouch can be set to a specific note, but this setting doesn't change dynamically, limiting its usability for polyphonic applications.

A workaround for Mac users involves using the 10.9 driver on macOS 10.14, though M1 compatibility may require alternative MIDI port solutions.

Users can set the PCR-500 to "class compliant" mode for wider USB compatibility, though this limits communication with the PCR Editor.

The PCR-500 can be switched to class-compliant mode by turning the "ADVANCED DRIVER" setting to "OFF" through a series of onboard menu selections.

The keyboard includes adjustable velocity and aftertouch curves, beneficial for players with tendinitis by allowing lighter touch responsiveness.

The PCR-500 is capable of sending polyphonic aftertouch messages, but the hardware only supports channel aftertouch, leading to user confusion.

The PCR-500 includes a Roland-style pitch/modulation stick, which some users find uncomfortable, but modulation can be reassigned to sliders or knobs.

Aftertouch strips in many keyboards, including the PCR-500, can be prone to failure over time, especially if not maintained properly.

The PCR-500's keybed provides channel aftertouch, which owners find comfortable and still functioning well even in older models from 2007.

The PCR-500 is often compared to the Ensoniq keyboards for aftertouch features, though the latter provides true polyphonic aftertouch at a similar or lower price point.

The PCR-500 allows full controller programming onboard, unlike the A-PRO series, which requires computer-based programming.
