<DIV><FONT face=Arial size=2>In the circuit shown, the 4051 selects from 8 wah
frequency pots. Glide would be simple to add if the 8 wah frequency pots were
replaced with 8 wah frequency control voltage pots, and the resulting CV was
sent to a voltage controlled resistor (VCR). Then, the CV could be run through a
standard lag circuit for "glide." The VCR would replace the original wah
frequency pot. Perfect, right? Nope.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Minor problem #1: voltage controlled resistors
don't really exist. </FONT><FONT face=Arial size=2>This is the type of situation
where a CA3080 OTA or a Vactrol is usually employed.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Minor problem #2: That's the limit of my technical
knowledge! I really don't know if an OTA or Vactrol would work well in this
application. Hopefully, someone else will the baton* and run with it.
(Please?)</FONT></DIV>

possible?</DIV>
<DIV><BR></DIV>
<DIV>Hello list! My name is Jason Stout and I need a reality check, and some
advice.</DIV>
<DIV> </DIV>
<DIV>How possible, or practical, is the addition of a glide circuit to this
sequencer:</DIV>

<DIV> </DIV>
<DIV>How would it be done?</DIV>
<DIV>I can't see it happening, but if it is practical, I think you
guys would know. </DIV>
<DIV> </DIV>
<DIV>Thanks!</DIV>
