Analogue systems

Hello All,

I am currently trying to map out a modular system for myself.  I have already emailed Bob 
at AS and he has given me some great advice but I thought i'd open it out for other people 
to throw in some ideas.  I am a producer/engineer (mainly guitar based stuff) and want the 
system to act a a processor for external sounds as well as being capable of sound 
generation/synthesis.  Basically i want versatility.  Also, as a footnote i am a huge fan of 
the Synthi hence its inclusion and also want the moog filter for a particular project i have 
coming up.

Any comments and feedback would be greatly appreciated!

Here is my list so far:

RS270 - 3.5mm to 1/4 inch jack convertor
RS70 - Pre-amp
RS85 - LFO
RS95 (x2) - VCOs
RS180 - VCA
RS120 - Comb Filter
RS35 - External Processor
RS100 - Moog Filter
RS60 - ADSR
RS20 - Ring Mod
RS500e - Synthi Filter
RS510e - Synthi Trapezoid
RS165 - Signal Mixer
RS15 - Case

Is there anything that I have omitted or perhaps i'm going a little module crazy for a 
newbie?!  Perhaps there are modules made by other manufacturers that would better suit 
my purpose?

Thanks in advance,

Dan
