i'm planning a patch that will listen to live acoustic instruments<br>
(via fiddle~or sigmund~) and then trigger some effects when the<br>
analysis objects detect certain frequencies. the catch is that i not<br>
only want to trigger these fx: ideally the effect should be sustained<br>
until fiddle or sigmund detect some other frequency. below is a small<br>
piece of code that works for this (triggers at 400, stops at 500), but<br>
i'd love to see other approaches, especially if they are less<br>
cumbersome (because i don't wanna do this with a pair of frequencies,<br>
but a bunch of them!)<br>
thank you!!!<br>

<div>When the pitch falls within the range, [inrange 36 48] reports 1, as soon as the pitch leaves the range, it reports 0.</div><div><div><div><div>I may have overlooked the existence of an object that does this, but anyway, maybe it's insightful for you to see a way to do it with basic objects.</div>
</div></div></div><div>Instantiate one for each pitch-range you want to monitor.</div><div>gr,</div><div>Tim</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
