ehx micro synth pcb layout/perf/vero etc

[Br4d13y]

anybody got a layout for this??  i want to build this monster

You don't need a layout for veroboard, you just start soldering a section at a time and test it before you go on to the next.  It's just something I have always found very easy - unlike hanging wallpaper!!!!!

i would prefer pcb though... it would kinda make a less stressful debugging phase, which is garunteed to occur

This guys also got a guitar synth somewhere on his site and even sells kits or just PCB's.

The idea being that you can work through his explainations to build and test the separtae blocks then when it all works you could then approach the EH micro synth.

Here's a Micro synth gutshot: http://farm3.static.flickr.com/2399/2165679711_84a204e13a_o.jpg

Maybe ten 4558's and a half dozen 3094's. And a 4013. I expect it would fit on a 160mm x 100mm perf quite nicely, especially if 13700's were subbed for the 3094's.

i found the guitar trigger on the mfos site, can i use this circuit and run it into like a standalone vco or vcf? i don't fully understand synth stuff, but i am looking to achieve the awesome sounds created by one with the guitar. i just thought that the trigger might be a good point to branch off of into other blocks of a guitar synth

[Br4d13y]

so i searched around and had some ideas as  i was looking

you would have to convert the guitar signal to a 1v/oct to use it to run a vco, i found this to convert the frequency of the guitar to voltage

then i gound this to convert the voltage to the 1v/oct for the vco

how does that look to you guys, possible?

Not without extracting the fundamental first. Why reinvent the wheel when EH did it 30 years ago?

[Br4d13y]

sometimes the reinvention of another material can lead to a better understandimg and eventually complete usefullness of a product

how would you extract the fundamental, i infer this is the initial frequency output by the guitar?

First read this thread:

Then go to the search function and search fundamental extractor.
Lots of good reading there.
Happy trails...
