[sdiy] coupler module

[Peachey, Dave]

Tony,

>  I certainly want to build an input module sometime.  Definitely both line
and mic inputs.

For an example of a module which provides both mic and line level inputs
(boosted up to 10V modular synth levels) plus an envelope follower with
additional gate and trigger outputs, you could check out the External Input
module in the Digisound modular synth (module 80-13 - I suggest you look at
Anders Sponton's site for pdfs as I haven't got around to digitising mine
just yet).

I suggest this for no other reason than I have one which works/worked very
acceptably for boosting mic and (bass) guitar inputs for processing within
my modular system (when it was set up).  Also - no CEM chips in that module
;-)

Cheers
Dave
