A.When compared to the PCR-30 / PCR-50 / PCR-80, the PCR-M30 / PCR-M50 / PCR-M80 have been improved in the following ways.
- The PCR-M series uses a new keyboard. This improves playability, and reduces key noise while playing the keyboard.
- Four new types of velocity curve are provided.
In addition, you can switch between three levels (LIGHT, MEDIUM, HEAVY) for each of these velocity curves.
Since this gives you a total of twelve types of velocity response, you can choose the velocity curve and level that's just right for your keyboard playing style.
(The PCR-30 / PCR-50 / PCR-80 are not equipped with a touch level selection such as LIGHT, MEDIUM, and HEAVY and other velocity curve selection kind of things.)

- A new fixed-velocity mode has been added.
You can transmit a specific fixed velocity in the range of 1--127 regardless of your keyboard playing dynamics.
(The Velocity Offset function of the PCR-30 / PCR-50 / PCR-80 has been eliminated.)
- Similar to the assignable control of the PCR-30/50/80, you can now send keyboard performance data from the MIDI OUT connector while connected through USB.
(Interface mode has been added)
