This patch consist of an 3 rows, 9 steps analog sequence controlling differents 
modules. This file is in ADPCM .wav format, 16 bits,32khz
Modulation routing
--------------------
Analog sequencer : Row A -----> Vco frequency (PWM)
                   Row B -----> filter cutoff 
                   Row C -----> Q in of filter and PWM in of VCO
some manual tweaking of gain(VCA), filter initial frequency, and inital
PWM (VCO).

Signal routing
----------------
VCO ----> VCF ----->VCA -----> output


all the module are in Barry Klein's book.

Vco=Electronote tri-square 
Vcf=ssm2044
