Re: [Doepfer_a100] Re: Module idea : L-R to M-S to L-R

2008-02-07 by Silas Johansen

I like the idea, but I'm not sure I would like something like that in
a module - I would probably prefer a stand alone unit so I could use
it independently of the modular - and preferably with line-level
signals.

Also, I'm not sure whether this would sell - I think it would be
geared more towards sound engineers than synthesists. Or at least when
I think of the possibilities this would give me I think more as a
sound engineer than a synthesist...

Cheers,
Silas
