Dynamic Pads:

Roland markets these pads as though they are suitable for finger drumming, but they wiggle horizontally and have a little room to press down before registering a note press. These pads are more suitable for sending Bank/Program Change messages or for controlling "on/off" type parameters in your DAW host (mute, solo, etc.) If you need pads for finger drumming, these are not a good solution. For quality pads, I recommend the KMI QuNeo controller (which can also send aftertouch and much more.)

================================================


[Value] Knob:

This knob has good build quality. It's stepped and can be pressed down, which functions as the [Enter] button. You'll need to use this often if you're a tweakhead, so it's good to know it feels rugged.

LCD Display:
The LCD display is small, but legible. It has an orange backlight which is always on. You can adjust the contrast but I find keeping it at maximum contrast is sufficient for legibility. It displays the currently broadcasted continuous controller value as a number, or the current velocity value using "bars" of different length.

Side Panel Connections:

The connections for USB, 5-pin MIDI I/O and 1/4" pedal connections are snug. I'm not worried about cables falling out during a performance. This is a big plus. The switches for "USB/OFF/DC" and "MIDI Merge OFF/ON" have a good click and require a good deal of force to move. They're small and shouldn't get in the way.

================================================


Driver Stability:
I'm using the Windows 7 64-bit driver, and it's working perfectly so far. MIDI timing feels very tight, with no sluggishness at all.

================================================


Programmability:
The A-Pro comes with the free A-Pro Editor. The editor lets you assign various MIDI messages to any knob, slider, pad, button, the aftertouch strip, pedals, pitch bend lever and modwheel lever. This customization is very powerful for controlling host software, plug-ins and virtual instruments. If you're using something like Kontakt or Omnisphere, you can create all sorts of musically useful assignments for the A-Pro hardware controls. The A-Pro Editor is one of the biggest strengths of the A-Pro.

Messages which can be assigned to the hardware controllers:

- [NO ASSIGN] (The controller will not send any MIDI message. The exceptions to this are that hold, expression, bender, modulation and aftertouch controllers will send their default messages when set to [NO ASSIGN].)

- "Channel Message" types:

- Note
- Channel Pressure (Channel Aftertouch)
- Polyphonic Key Pressure (Polyphonic Aftertouch)
- Control Change (<= The most common messages to send. Ex: Modwheel, Volume, Pan, etc.)
- Program Change
- Program Change (Min-Max)
- Bank Select + Program Change
- Program Change - Dec (decreases value by 1 with each press)
- Program Change - Inc (increases value by 1 with each press)
- RPN (Registered Program Number)
- NRPN (Non-Registered Program Number)
- Encoder Simulate (specify a Control Number)

- System Realtime/F6

- System Exclusive Messages

- Free Messages

- Tempo

================================================


A-Pro Editor highlights:

- Store presets (called "Control Maps") on your computer as .mid files
- Send and receive Control Maps to and from your A-Pro controller
- Export and view MIDI message "Assign Lists" as .html files in a web browser
- Copy/Paste settings from one hardware controller to another for fast programming
- From "Options > Show messages" displays any mapped MIDI messages directly above the GUI controllers as well as the assigned MIDI channel
- When "Show Messages" is enabled, the boxes displaying MIDI messages and channels are color-coded, indicating which port(s) the hardware controller is broadcasting on (Port 1, Port 2 or both ports)
- Stores changes to a controller even if you don't click [OK] in floating window. Great for fast programming.
- Freely assign min & max CC values (Allows support for sustain pedals without a "reverse polarity" switch.)

Create Keyboard Sets:

- Keyboard Sets define splits for Upper and Lower play zones on the keyboard.
- Each play zone can cover any range of notes included on the controller (A-300 has 25 notes, A-500 has 49 notes, A-800 has 61 notes)
- Each play zone can be mapped to any octave, any MIDI channel

================================================


Aftertouch Strip Adjustment:
WARNING: Perform this adjustment at your own risk! Opening the enclosure and modifying the electronics will void your warranty!

Having said that, the fix is relatively simple. Just take your time and keep track of the screws. Below, I've provided a few links which describe how to perform this fix. Pictures are included in the top two links.
