[sdiy] Linear Analog Synth Portamento

[Tom Wiltshire]

Just for references, there have been a couple of discussions around the various types of portamento you can get by having either linear CV or 1V/Oct CV with either RC or linear integrator-based portamento circuits. All those combinations give a slightly different effect.

If you're curious/interested/bored, have a look for "glide" in the archives, and look for September 2010 and Jan 2011 particularly.
