I think it would be more useful to place an attenuator for the frequency mod depth where that bipolar aux wave level control is currently located....
which sort of additional mixer do you MuffWigglers prefer ?
I planned a few inside and I'm looking at some cheeper ones
Have my eyes on
CGS 081 in "Mixer"-Option but useful too for CV
Manhatten Analog MIX https://manhattananalog.com/products/mix
YuSynth Mixer http://yusynth.net/Modular/index_en.html
to what else I should look (as I'll build the panels for myself, I could use EURO-DIY too) ?

| br>The Yusynth VC Panning Mixer is a great option! You can build it with or without the Output Module.
The panel for the combination of the two modules is complex but it is available from RE:Synthesis. Dealing with RE:Synthesis was excellent and the panel is totally awesome.
If you make the single version you can fit in a 2U panel. There's a picture of sduck's version on Yves' site.
Having an internal mixer has been a really great feature for me since I added it. The added bonus of stereo panning with voltage control really makes this a great module. br> br>

The Doepfer A-135-1 is a nice unit, Analogue Haven lists this unit at $190.00. http://analoguehaven.com/doepfer/a-135-1/

The A-135-1 inputs are normaled together, as are the CV inputs. Inserting a plug in to any of the inputs "downwind" of something else breaks the normal connection.
Said another way, if you plug in to Channel 1, ch's 2,3,4 are norm'd to ch1's signal. Inserting a patch cord in to ch2 breaks the norm'd connection between ch1 and ch2, and now ch2 is what ch's 3 and 4 are norm'd to. The same thing happens to the CV inputs.
The individual outputs are set up like the MATHS 2013, in that if you plug in to (let's say) ch2's output it is removed from the "mix out" jack. This is true for all four channels' outputs.
The neat thing is that all of this is optional, removing jumper links "un-norms" the connection that the jumper link is associated with.
I took it one step further, I replaced the jumper links with minitoggles.
The VCAs are linear btw.
If I've successfully confused the FEK out of you, here's Doepfer's explanation of how the norm'd connections work ......

Quote from manual .....
From January 2014 a revised version 3 of the A-135-1 is shipped. Compared to the previous version 2 of the A-135-1 the inputs and outputs of the new version are normalled adn [sic ... *and] for the sum output it can be chosen between all and selected VCAs:
All signal inputs are normalled, i.e. signal input #1 is normalled to signal input #2 unless a plug is inserted into signal input socket #2, same is valid for the signal inputs 2 > 3 and 3 > 4, each normalling (1>2, 2>3, 3>4) can be interrupted by removing a jumper
All CV inputs are normalled, i.e. CV input #1 is normalled to CV input #2 unless a plug is inserted into CVl input socket #2, same is valid for the CV inputs 2 > 3 and 3 > 4, each normalling (1>2, 2>3, 3>4) can be interrupted by removing a jumper
the mode of the sum output can be chosen between "All" and "Selection" by means of a jumper. In "all" mode all four VCAs are mixed together. In "selection" mode a VCA is removed from the sum signal when a plug is inserted into the corresponding single output.
Link to jumper PDF .... http://www.doepfer.de/a100_man/A135_1_V3_jumper.pdf
This PDF diagram shows precisely where the jumpers are located on the PCBs, as well as describing which jumpers are associated with which function.
Perhaps this information will help you include or exclude the A-135-1 as an eligible choice in your system.

| br>BTW, this is relevant to MU ... I use Euro for nothing but modulating and controlling my small MU system .......
| br>CGS 004 is super simple. Works fine for both audio & CV.
CGS 081 is great, too, but if you're just wiring it up as a mixer, you're better off with the 004. br> br>
