<p>Hi, I've built a classic stereo delay using [delwrite~] and [vd~], and L/R crossed feedback. This works! </p><p>
 Now, I want to insert an effect into the feedback path. (many 
possibilities here: add some bitcrush, so each repeat gradually becomes
 more distorted.... or a [hilbert~] type pitch shift, which might create
 something like Shepard tones, etc).</p><p> <b>This works when everything is within a single patch or abstraction. </b></p><div class="gmail-text_exposed_show"><p>
 However, when I try to allow the effect to be external to the 
abstraction (like a SEND/RETURN insert on a mixer), when I try to 
complete the circuit, I get "DSP loop detected". <br><br>The two circuits are essentially IDENTICAL! <br></p><p> This seems like a bug to me. Any ideas? </p><p>
 I've attached pix of both the high-level schematic, along with a demo 
patch. (I can upload the actual patch if that would be helpful). </p><p> Thanks!</p></div>
