Hi Gabor,<br>
<br>
Thanks for answer.<br>
<br>
I solve some issues whit the explain you give me, now I have the following<br>
code:<br>
<br>
//<br>
<br>
(define (mid)<br>
(define note (midi-note))<br>
(define vel (vector-ref note 3))<br>
(display vel) (newline))<br>
<br>
(every-frame (mid))<br>
<br>
//<br>
in the REPL appears the numbers I receive from the midi device....<br>
<br>
I can take those values of "vel" to scale some objects (for example), but in<br>
some time it sends me an error in task, because expects type <vector> and<br>
given " #f ", or in other examples expects procedure and given the same " #f<br>
"; this #f value appears when no midi message it's sending from the device.<br>
<br>
I'd been trying to turn the not number value " #f " to "1" but can't yet,<br>
<br>
How do you think I can to ignore this error?<br>
<br>
Thanks<br>
<br>
Eduardo.<br>

#f means false, you can use a conditional expression for testing,<br>
something like:<br>
<br>
(define (mid)<br>
(define note (midi-note))<br>
(define vel (vector-ref note 3))<br>
(when vel<br>
(displayln vel)))<br>
<br>
i suggest that you should read the fluxus manual and the racket<br>
documentaion to have a better grasp of the basics of the language.<br>

That's good advice.<br>
<br>
I'd like to suggest re-naming this;<br>
<a href="http://www.pawfal.org/fluxus/documentation/" target="_blank">http://www.pawfal.org/fluxus/documentation/</a> to "getting started" and making<br>
it refer to the examples directory and the racket docs in addition to the<br>
stuff that's already there.<br>
<br>
I took the liberty of adding the Racket reference here;<br>
<a href="http://en.flossmanuals.net/bin/view/Fluxus/Scheme" target="_blank">http://en.flossmanuals.net/bin/view/Fluxus/Scheme</a> It's such a valuable and<br>
immediate resource that I feel it should be there. I don't imagine that<br>
people starting out with Fluxus feel like reading a whole book when they<br>
just want a single function to get something done right now. If we can keep<br>
them happy for a playful evening or two then the books will be useful for<br>
the longer term in-depth perspectives. I think the Racket reference serves<br>
well for that.<br>
<br>
Feel free to edit my addition if that's the wrong spot or it has other<br>
issues.<br>
<br>
Yours,<br>
Kas.<br>
