&gt;             &gt;&gt; Hi dear folks.<br>
&gt;             &gt;&gt;<br>
&gt;<br>
&gt;         [...]<br>
&gt;<br>
&gt;<br>
&gt;            I had a thought re keyboards (particularly the keys<br>
&gt;         themselves). Why<br>
&gt;            can&#39;t the surface of a key be a touchpad-like surface<br>
&gt;         sensitive to<br>
&gt;            pressure and even movement? So, for example, you could play a<br>
&gt;         violin<br>
&gt;            note, hold it, and use finger pressure and movement on the<br>
&gt;         key surface<br>
&gt;            itself to do vibrato the way a violinist would? That would go<br>
&gt;         a long<br>
&gt;            ways toward bringing human expressiveness back into playing<br>
&gt;         the sounds<br>
&gt;            of such expressive instruments as strings and woodwinds.<br>
&gt;<br>
&gt;<br>
&gt;         Yes, that would be great. But AFAIK the circuit inside keyboards<br>
&gt;         just cares about keypresses; nothing about pressure or velocity,<br>
&gt;         although maybe something could be hacked given the present<br>
&gt;         keyswitches, electrical contacts (or I think capacitors on old<br>
&gt;         ones), scan codes and other stuff.<br>
&gt;         Do you know any work about that?<br>
&gt;<br>
&gt;<br>
&gt;     Sorry, I should have mentioned that I was talking about musical<br>
&gt;     keyboards, not computer keyboards ... although I suppose you that if<br>
&gt;     you ganged some Trackpoints (IBM&#39;s little eraser pointer tool)<br>
&gt;     together, you could get take advantage of the Trackpoint&#39;s<br>
&gt;     directional abilities.<br>
&gt;<br>
&gt;     It was just an idea that I think would be great. Don&#39;t know if<br>
&gt;     anyone is working on anything even remotely like it...<br>
&gt;<br>
&gt;<br>
</div></div><div class="im">&gt; Ok :).<br>
&gt;<br>
&gt; Then, I&#39;m not sure, but I think what you refer is called &quot;aftertouch&quot;:<br>
&gt; <a href="http://www.google.com/search?q=aftertouch+keyboard" target="_blank">http://www.google.com/search?q=aftertouch+keyboard</a><br>
<br>
</div>Hmmm, hadn&#39;t run into that. I read the Wikipedia article about it. The<br>
three forms of aftertouch they mention don&#39;t seem to include my idea of<br>
directional movement while holding the key down.<br>
<br>
But an array of Trackpoints might be interesting as a control input, too.<br>
<div class="im"><br></div></blockquote><div><br>So you say something like to achieve little variations of notes (&quot;vibrato&quot; alike) depending on the key/finger movement, isn&#39;t it? I think there is something like that in really expensive keyboards/controllers, but not sure.<br>
