<p>I have overlooked this type of sensing arrangement in key form,
but it seems a good way to do certain things. Roman suggested a
sensor which I am going to look into also. <br>
</p>
<p>This type of linear sensing can also sense velocity just like two
switches do now in most keybeds, just by setting two thresholds.
So you get the linear and switching at the same time and it's
adjustable. Very useful.</p>
<p>I hear you Brian Willoughby, and I think we would need to
reformat the key layout. I would not want to use a Wooting
straight up, that would be strange no? Those keys are sort of fake
keyswitches with a hole in the bottom. There may be other gadgets
that can be used to make the same thing.<br>

things:<br>
<br>
First, USB is not necessarily the best choice for musical
applications. It’s not more responsive, although it does have
more bandwidth than classic MIDI. If a MIDI “device” has
nothing queued up yet for transmission, then a new event will
have a latency of 0.32 ms, or as little as 0.032 ms, depending
upon how the receiver handles timing. A USB Device can support
a typical average latency of 0.5 ms, but that’s only when the
USB Host is designed to guarantee such latency. It’s quite
possible for a USB Host to postpone USB traffic for a given
Device, such that there is no upper limit on latency until you
get to about 10 ms.<br>
<br>
If you’re willing to change over from classic MIDI to RTP-MIDI
or any of the other modern transports, then you’re suddenly
better than USB in basically all respects. Granted, the
bandwidth limitations of classic MIDI are nothing to ignore,
but we’re not necessarily stuck with only classic MIDI or
USB-MIDI. Responsiveness is more than just bandwidth.<br>
<br>
<br>
Second, I don’t think that a typewriter keyboard is the best
ergonomics for music. The mechanical design of a musical
instrument is potentially a huge issue that isn’t solved
merely by the availability of raw sensors. Although the
Wooting seems promising, adapting it to musical applications
could prove to be an involved endeavor. The Eigen technology
is similar, and has four optical sensors per key, allowing for
side-to-side and front-to-back motion detection as well as
simple downward pressure. I don’t think it would be easy to
build an Eigenharp from Wooting keys.<br>
<br>
<br>
That said, thanks for sharing. It’s certainly an interesting
option, especially for folks who are already considering
making their own musical controller.<br>

uses DirectX joypad APIs and each key has continuous depth
output. It's 160 €. USB sure beats midi for responsiveness and
the rgb lighting could have musical applications as well. What
do you guys think?<br>
