The A143-3 is the Quad LFO. IMHO the systems lacks A180 Mult; A138
Mixer; a 2nd EG and VCA. Personally I think the A131/A131 great (off
set voltage; 2 in 1 mixer) but if money is a constraint then an A132
will do it. A132 will give an add. VCA while the 2nd VCA could be used
for AM-sounds. The 2nd VCA will team up with the A155, when acquired,
nicely for more vivid patterns. A noise source is also obligatory, I
think. Regards, Ingo
