hi joe, doepfer recommends the A117 because of the 808 sound source
part has 2 sound sources which are harmonicaly rich and complex and
the digital noise or you could use the A118's straight white and
coloured noise which contains all the frequencies both flat and
coloured with different spectrum shifts.

what the A117 has is a tuned bank of sawtooth oscillators. the plus
side is you have a harmonically rich source, the down side is you
have no tuning available on the source. you could always use an A121
multimode filter to modify the source. but remember if you are using
it as an unvoiced source, having the ability to tune the source is
redundant. same goes with the digital noise. if you use an A147 lfo
which is synced to the tempo of your track, you could use it to
modulate the A117's digital noise and have a random synced source for
your voiced or unvoiced input. you could also use an A115 divider as
a real time modulator for the the A147's vc input. the best thing to
do is to experiment, think outside of the box.

to really implement the vocoder to its maximum capabilities, you
would need to have the A129-1/2, 3 A129/3, 3A129/4 and 1 A129/5.

you will then need a compliment of modules for sources, modifiers and
processors. you will need an A119 for input and envelope follower
functions to bring an external source for the speech input. you will
need an A117 and an A118 or both as a source for the unvoiced noise
input. you will need at least 1 A110 or A111 for the voiced input.
you will need a mixer to mix the vocoded output with the high out of
the A129/1. you need at least one of each following to control the
A129/4, 1 A147, 1 A132, 1 A148 and 1 A140.

if you wish to have more control, you can add the A191 & A192 to
record, edit and playback your vocoded material. another suggestion
would be to use the A129/3 slew-limiters after the A129/1 analysis
section as manual controllers before the A192 for a rough realtime
sketch for further editing in your pc sequencer.

if you want to have a smooth transition between the voiced and
unvoiced inputs, you will need 2 A170's or A171's if you wish to
voltage control of the transitions, 2 A130's, 1 A165 and 1 A138 to do
the job.

i have 2 portable A100 cases dedicated to external processing, here
is the layout
case #1

top A117, A148, A147, A171, A171, A132, ASo MX224, ASo MX61, A115
bot A177, A119, A119, A129/1, A129/3, A129/3, power supply

case #2
top A129/5, A129/4 ASo Mx224, 2 x A121, 2 x A125, 2xASy rs120, A134
bot A129/3, A192, A191, A136, A136, ASy rs60, A138, power supply

i also change modules around when more of one needed than the other.i
plan build next case to include 1 more A124, 2 A127, 2 ASy rs240
frequency shifters, 2 ASy rs310, 2 A103 and 1 A174.

once the Analogue Systems VC delays arrive i plan on building a
special 4 row case with 168 hp per row. i hope some this helps you in
your quest for a vocoder.

regards,
RM
