<div dir="ltr">Hi,<br><br>nice to hear someone is interested :) quad lives!<br><br>A scanner is one way to do it but the person I have in mind for this is more interested in gestural motions so dual voltages for X, Y positioning is more convenient I think. <br><br>I'm happy to chat about the fundamentals of the idea, the circuit itself is not really finished yet. <br><br>What I'm playing with right now derives "quadrant" voltages from joystick X and Y inputs to control 4 VCAs that would be for Front Right, Rear Right, Rear Left and Front Left speakers. There is equal power breakpoint panning between adjacent channels. The equal power law is adjustable, I'm not sure which would be most appropriate yet (-3dB, -4.5dB, -6dB). Single-axis panning goes down to full closed in the center and back up when going straight across. Controlling it with a joystick, joystick straight forward sound would come out of both front speakers at a slightly reduced amplitude, rotating joystick to the right it would come out stronger out of only the front right speaker, and as you continued to rotate around it would crossfade smoothly from speaker to speaker.<br><br>here is the simulation fully rotating around:<br><a href="https://imgur.com/a/gpEKb8V">https://imgur.com/a/gpEKb8V</a><br><br>and here is the simulation of single axis front-to-back motion:<br><a href="https://imgur.com/a/Pt6SyTf">https://imgur.com/a/Pt6SyTf</a><br><br>best,<br>-dk<br><br><br><br></div><div dir="ltr"><br><div><br><br><br><br></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Apr 20, 2020 at 10:49 AM ulfur hansson <<a href="mailto:ulfurh@gmail.com" target="_blank">ulfurh@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">i'd be highly intrigued in learning more about this subject as well. it would basically need an equal power interpolating scanner?<div><br></div><div>if you are willing please share!</div><div><br></div><div>many thanks,</div><div>-úlfur</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">mán., 20. apr. 2020 kl. 01:58 skrifaði Dakota Melin <<a href="mailto:dksynth@gmail.com" target="_blank">dksynth@gmail.com</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi everyone,<div><br></div><div>I've been playing around with some ways to pan signals in quad systems this weekend and I'm looking for resources on the subject. <br><br><a href="https://i.imgur.com/3UIU7gG.png" target="_blank">https://i.imgur.com/3UIU7gG.png</a> <br><br>Serge T mentioned a CalArts paper on the subject by Darrell Johansen.
