Alexandre,

It's possible to link two A-138 to obtain a 8 channel mixer. I can add a
corresponding note to the DIY page. Let me know if you are interested (one
integrated circuit has to be removed and two cables have to be soldered
between the two A-138). An passive expansion module for the A-138 with 5
inputs would be possible but not cheaper as the expensive mechanical parts
(potentiometers, knobs, sockets, front panel) are the same. But we will
"design" such a simple electronics (it will take about 30 minutes) and see
if there are suffient inquiries to produce that mixer expansion.
Best wishes
Dieter Doepfer

Hello,

Me, somehow I really like the idea of extension for A138 with 5
channels... to make easy
cheap 8 step sequencer with A160/161 and another A138...
