i just made a very short sample of the switch in audio range. it is set up as follows: the triangel and sine outputs of my TH8038 VCO are routed to I/O 1 & 2 of the switch that is set to 2 step mode.
1st i switch manually, then i switch with a 2nd VCO/LFO, which is controlled by another LFO then (falling sweeps). after that i clock the switch by the TH8038 VCOs square output, then divided by 2, then by 4 (using my simple clock divider).

Drool!

Is the 'zipper noise' avoidable, or is that the point of the module?

This module is mainly used to switch between voltage sources,not audio.

U can use it for audio in switched sequence but then those 'tiks' u get on top of it are normal.

thanks Matt for the demo,and bringing this simple but wonderfull usable module

there are a lot of DIY-boards out there without any standard headers... so "something is better that nothing"?!

when ever possible i don't build boards without PSU Headers.


btw.:
the dotcom connector can use the pads from one row of the doepfer Header,
you just need to place a sixt pad, and you must change the Ground plane on that row
---> dotcom has the Ground only on one pin, and +5V on a pin that goes to Ground if not changed a little bit.

dotcom pinout:
V+
NC ....( Grnd on doepfer)
+5V...( Grnd on doepfer )
Grnd..( Grnd on doepfer )
V-
NC ( ok, not really necessary )

okay then... now almost everyone should be fine, i think. i added the MTA-156 connector and modified one row of the euro-style ribbon connector to comply with the dotcom standard. the footprints for the beads now have a .039 drill.

BTW, all who indicated interest in this thread so far are on the list. i don't think it is necessary to PM all of you before the boards are in...
however, don't hesitate to contact me in via forum, PM, e-mail or whatever.

I think I may have read this wrong... I paid for one + shipping already, using the paypal address I already have for you, is that ok?
