I want to introduce you the "Volta's Expresso"(picture at the end of the post),
my custom dual Cv converter made by Piotr from Hexe Guitar Electronics.
I'm really happy to show you this utility pedal and I think that maybe some people here can be interested on it because of the possibility to use it to create wobbling and so, for electronic and dubstep stuffs

.(obviously you need a generator of LFO(moog mp-201,or the GoatKeeper gk3 in my situation)).
Let me introduce it.
It has:
-cv input(0V to +5V only)
-2 exp pedal inputs(I use 2 moog ep-2)
-2 exp outs(the Volta works only with pedals that have a input
voltage range from 0V to +3.3 V)
-2 footswitches that allow me to change, for each channels,
the source that control the exp outs and so I can change
through expression pedal input or cv input to control the
parameter I want(for example the cutoff of my Xerograph

)
-a toggle switch that allows me to set the exp1 in as the
expression pedal that controls both exp outs when the
cv is disabled.
So this utility pedal is useful if you have different pedals that don't accept Cv signal but only exp pedal (as the IE pedals) and if you have a generator of Lfo as the Goatkeeper that has a lfo Out(cv out).
In this way you can control the parameter you want through the Lfo out of the Gk3 and so you can choose the waveform,the depth,the speed and the metric subdivision creating differents pattern that will affect the control you want (controlling the Cutoff of the Xero rules

)
Then you can control two single parameters of two different pedals(for example the cutoff on a filter and the sample rate on the FrantaBit) with one single exp pedal.
You can have one pedal controlled by your foot and another by the LFO of the Gk3.
It has a large possibility of use I think
Here there are some clips I've done using the Volta's Expresso,Oc2,Xerograph and FrantaBit and the Gk3 as generator of LFO.
The drums I used comes from Reason 5.
P.S. There are other clips of other different settings of Iron Ether pedals.I will load other clips later.
This is a part of a song that we're writing down with my band "Vog":

Hope you like these clips and the idea of this utility pedal

Let me know what you think about it
P.S. Piotr from Hexe Electronics Guitar is a great builder!In two weeks he did this device and he sent to me a lot pictures of the projects starting from the 3d model,the PCB desing and then the pictures of the pedal finished.
A great man!
