OK :)

>a) 3 pots, 6 jacks:

(jacks cost less than pots, LED's draw current and make noise)

1) RATE
2) FM
3) OFFSET

6 jacks:

1) FM IN
2) LFO 2 IN
3) TRI 1
4) TRI 2
5) SQ 1
6) SQ 2


Two linear tri LFO's, two square shapers, no tempcos, no sine shapers, no
LED, purposely unstable -- uses $5 worth of circuit board parts ;)

OFFSET and FM are reversing scaling attenuators.  OFFSET is normalled to a
positive voltage.

The input to LFO 2 is either LFO 2 IN  or the input to LFO 1 plus OFFSET
(using a switched jack).  When LFO 2 IN is used, OFFSET becomes its input
attenuator. This way you can patch the output of LFO 1 into LFO 2.

TRI 1 and SQ 1 use switched jacks -- unswitched, TRI 2 and SQ 2 contain the
sum of 1 and 2.  Offsetting SQ 1 to SQ 2 will simulate PWM.

Want a slow 1U saw??  Use a 310 or 800 :)
