<br> <br>yes, that's right. the feedback path is provided in the ugen itself.<br> one drawback is that it's not possible anymore to have a delay of 0<br> samples (which for a feedback delay makes no sense anyway).</blockquote>
<div><br>Zero length delays should still be attainable through putting the unit in bypass mode, using the .op() function, I think. Kinda trivial but could become relevant.<br><br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br> <br>i don't know about submitting. the delay ugens are part of the STK<br> which also exists as a library independent from chuck.<br> so changing something in there is not so easy. </blockquote><div><br>Well, aside from Perry Cook himself being on this list as well, there are already differences between the STK and ChucK versions of some STK Ugens. It's a different context, different choices may make sense. For example; the envelopes come from the STK but in ChucK they have some member functions that take variables of type duration. There are more examples, mainly convenience stuff.<br>
<br>I don't think the library-nature of the STK needs to be a issue on it's own<br> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
also i think e.g.<br> DelayA is used by other STK ugens as well.</blockquote><div><br>That wouldn't need to be a show-stopper either because those wouldn't use the feedback. Oh, now it sounds like I'm arguing either way, I was really just pointing out factors.<br>
</div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> might be better to have dedicated (interpolating) delay ugens with<br> integrated feedback path - maybe there is already something like<br>
that. coulnd't find any in the ugen list, though.</blockquote><div><br>I can't find anything either. I think LiSa could be tricked into becoming one using her feedback but I'm not sure right now if that would have the extra sample.<br>
</div><br>We'll see what Ge & Perry think.<br><br>I'm at least going to add a note about this feedback/Z-1 issue to the Wiki's page for suggested additions to the manual. At the moment I don't think the manual covers the calculation order at all yet it's quite important, in a way it could be considered a part of being "strongly timed".<br>
