Or, perhaps the raw CV signals could be multiplexed straight into the
inputs along with a master clock signal on another channel for demuxing
somewhat like SMPTE? <br><br><div><span class="gmail_quote">On 10/5/05, <b class="gmail_sendername">Jeff Farr</b> <<a href="mailto:moogah@gmail.com">moogah@gmail.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
I was thinking about 8 bands per audio channel, starting around 16k on
downward in octaves. However, I realize this will take a steep BP
curve to decode so that there is enough headroom between bands for good
resolution, I'm not sure what kinds of slope can be easily achieved but
I imagine having 12 or 24db of space for each octave may not be
high enough for a good resolution 'decode'. <div><span class="e" id="q_106c2720c92bb580_1"><br><br><div><span class="gmail_quote">On 10/5/05, <b class="gmail_sendername">Harry Bissell Jr</b> <<a href="mailto:harrybissell@prodigy.net" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
