Hello all! About to embark on my first modding journey thanks to your shared wisdom here. I wanted to add that I used a CTIA<->OMTP adapter to connect a TRRS headset splitter into the Monotribe for MIDI control. It was what I needed to connect with CV on the second ring of the TRRS.

Has anyone build a DIY MIDI OUT (only) for their monotribe?
In theory this would act as a CV(Hz/V) S_trig to MIDI adapter when connected to an MS-20???

How about VCF...can we control the filter cutoff with CV from a eurorack LFO or ENV? Or will the monotribe blow up? internal power rail is 5V right...wonder if it can handle +-12V hmmm.....

Does anyone know where to get that little 5 pin? cable that connects
with the serial port on the Monotribe. I want to fab my own MIDI OUT (only)
and want to keep my DIY work as neat as possible.
zaphod betamax
Internal to the VCF is +3.3V, you would have to attenuate whatever signal.
Try tapping a signal into the wiper on the cutoff pot. Can't say how the Monotribe would react. Probably have to crowbar the signal so it does not exceed 3.3V.

Do you mean the 6 pin connector?
You need a JST PHR-6 2mm connector housing like this:

And the matching crimp contacts or ready made crimped cables like this:

Sorry, I have only the links to a german ekectronic shop, since I bought mine there.

For MIDI out you need only 3 cables and it's probably much easier to solder directly to the underside of the 6 pin serial connector.

I've also been told a PS2 mouse contains the same connector.
Have not been able to confirm this.

Thanks! I realize now it is a 6 pin JST plug, I have been able ot find it on amazon.ca and mouse.ca.

Hello,
I've read some Wigglers were looking for Korg Monotribe LFO output mod. I made it for my friend and documented here (waveform shots, no cats):

https://syntherjack.net/korg-monotribe-lfo-output/

The most important thing - the schematics. Use it for your own responsibility smile



Hope you find it usefull,
Cheers

Literally woodshedding?! hihi

Sounds great, BTW!

Mine has been modified by a friend with the simple declicking solution and thus is now almost a new instrument. Before that it was short of impossible to record with it, but now it's a completely different story especially when controlling the Monotribe externally. Yes, at lower cutoff there are some thumps, but it's not that bad overall.

care to share how you de-clicked your MT?

Well, all the information about that mod comes from this very thread, so you just need to dig the depth of it. As I'm not all that knowledged in electronics myself and obviously don't want to give out any wrong data, I can say only, that the mod consists of only one cap and that's about it, not sure about the size though.
