Re: info from doepfer about the development of the A107 and the A154.

2003-06-10 by selfoscillate

hello,

yes i would also prefer a switch instead of a jumper.
as we can see with the a127, users start adding those switches,
because jumpers are not practical.

regarding the a154, i think most people who vote here always want
the solution with a maximum of possible features.
my personal opinion is, that this is not a bad thing.
it will give more possibilities, even if these possibilities
are rarely used in the end.

best wishes

ingo
