Yes - the banging is rather normal for these.
I've looked at, thought about, adding springs or more rubber.
My friend has recently bought two Kurzweil Midiboards, and I have created a three-manual master MIDI controller with those two on the bottom and a Kurzweil K-250 on top for a solo manual.
All three hook up to my MIDI Monster Mayhem Cabinet with various outboard rack modules and other goodies.
Sort of a cross between a Miditzer and a MIDI console.
ANYWAY, I digress. The main point of my reply has to do with the action of the MIDIboard.
I had a MIDIboard back in the day, some 20 years ago. Used it live in a rock band setting and I could never get the feel right. I started to think it was me.
No matter what I did with the MIDIboard setup, the action - or the response, just never felt right to me. So I sold my MIDIboard after we stopped gigging.
Zoom ahead to now, and I have been working the MIDIboard in a studio setting. Seems to be the same deal. As great as the MIDIboards are, they just don't ever seem to have the nuance, or wiggle, or dynamic control that I want in a keyboard.
Some things are fine - basic piano playing. But even then, there is no .... no grace between soft and loud. It's either soft OR loud ... not much in between.
Now I remember why I sold my Midiboard in the first place. Great keyboard in many ways .... but lacking in the nuance control of the action, in terms of dynamic control of MIDI modules.
Modern MIDI is better - and I think most good MIDI controller keyboards are better - will offer you a better dynamic control and feel.
But that is just me, maybe. Thing is to try before you buy, if you can.
Just that things have moved on since the Midiboard was released. And maybe even then the end result was not totally thought through 100%
My preference is for Yamaha keyboard action, followed by Kawai, then Korg and Roland.
Sometimes Korg keyboards are secretly made by Yamaha sub-suppliers anyway
fwiw - using latest version on Midiboards.
I have come to this realization:
Kurzweil keyboards playing other modules do not "feel" as good as going the other way around.
When I use Yamaha keyboards to play Kurzweil modules, I get better "feel" and tonal control.
Just my two bits.
These two Wikipedia entries explain why the Kurzweil Midiboard is not particularly graceful in the velocity curves, and why the Kurzweil K250 has no Aftertouch:
"The Midiboard had its virtues and its drawbacks. It was reasonable to manufacture and relatively inexpensive for the range of input forces, both presses and impulse inputs, it could transduce. One of its drawbacks was that it was not well damped in very light playing, making touch uncertain. At some point, working for Kurzweil, Hal Chamberlin debounced this burble. A hardware fix was possible - splitting the sensors."
