Dear members,

I designed a crossfader module based on Florian's suggestions. Here is the
link for the preliminary info:

www.doepfer.de/a138d.htm

It is only a preliminary version and should be treated as as basis for
discussions. From my point of view there are three possible ways:

1. A complete module similar to the suggested A-138d

2. An expansion module that has to be connected to an existing A-138 (a or
b). This would be a little bit cheaper as the electronics of the A-138 can
be used (but not much as the electromechanical parts remain the same and the
electronics is not very expensive). For this solution the single outputs
would not be available and a little bit of soldering is necessary (2 wires
have to be soldered to the A-138). I don't think that this solution is
meaningful.

3. same as 2. but only as a DIY project. It's very simple. Most of the work
will be the front panel processing. The "electronics" is only a few
resistors some potentiometers. I can publish the schematics on the A-100 DIY
page.

Bakis, maybe a poll will be helpful (thank you in advance ... :-). And of
course ideas/improvements of the suggested A-138d.

Best wishes
Dieter Doepfer
