10 outputs 4 inputs connected together with patch gloves

a touch interface design

simple useful vco

i looked at this one:
and then modified it so you can grab the triangle off of the capacitors and change the P.W. / triangle shape
cv in is clumsy, needs improving

uncertainty sauce

I haven't explained this well at all.  There is a little pot that has a copper pad on the base that is divided into 4, there is a non-conductive divide down the middle.  If you put resistors in one half and capacitors in the other then jiggle the pot you will get random varying resistances and capacitances between the pads of each pair.  These could be used to make freaky filters.  The speaker can jiggle the pot and make a nice shakey sound.

compander bear

A typical relaxation saw VCO. 
The first 4069 inverter just buffers the saw and drives an LED
On the 2nd inverter the center tap pot slides the LDR response across the input resistor, through center then across the feedback resistor.  So should this work as a compander yeah?

funny octave pattern thing

simple implementation of an idea for a funny old oscillator.  Modifications can easily be made by sending 'C' either high or low for acceleration or deceleration. This transverses 5 octave, can easily be modified to go through 3 or 2 octaves too.
