greetings forum members, a first post.
I belong to a pianists forum. Many of us are using a digital piano (DP) these days - limited budget, space, privacy (you can use headphones), low maintenance (no need to tune!) are the drivers.
The DP industry is still under the spell of the real thing, the acoustic piano (AP) upright or, even better, a grand. Relatively few of us get to own or even use one. So DP manufacturers are doing their best to emulate the 'action' of an AP - that is, to make it FEEL like one is playing the real thing, irrespective of sound (that's another story entirely). In fact the DP action is a radically different, grossly simplified version of the AP action but these days, in the modern DP, it's not at all bad.
(sorry to be droning on...)
In the DP forum of pianoworld we like to get stuck into the ins and outs of DP actions, the heavy ones (slower), the light ones (fast) and we have several 'theories' about what is happening mechanically when we play one.
Let me cut to the chase. Here (scroll to about 1/3 down the page) is an animation of one of the better DP actions.
We're trying to get an idea of the work required to play this particular keyboard. So we've coined terms like 'down weight' 'up weight' 'dynamic weight' and' inertia' but there appears, to me anyway, to be a half-cocked understanding of what is going on. Where is the inertia? How do we measure friction. How about inertia...etc.etc.
Could someone offer a lead for this enquiry? The questions raised may not be interesting enough here. Might there be a better forum? Does anyone here have any ready insight?
thanks for reading, and thanks for any suggestions...
