Replacing Buttons / Encoders on OT mk1

My baby has a faulty Scene B button (does nothing)
(2) Encoders do not function while in MIDI Mode

Not certain about the MIDI mode and the encoders, if to replace them or if it’s a bug, because the encoders work fine in regular track mode.

have anyone replaced these buttons. Simple thru hole? It was suggested to me it quite complex and I’m better off shipping it to Elektron LA, but I wanted some feedback from others if they’ve done it

Here’s a thread on replacing encoders. The last post contains a video of the process, and a method for restoring encoder performance without replacing the part itself. Very odd that they’re only broken in MIDI mode though, not heard of that happening before.

Also not heard of anyone replacing buttons on OT, but it apparently isn’t too difficult on monomachine.

Support is the way to go, i’m sure they’ll give you options, and advice on doing it yourself if that’s possible and what you choose to do.

What OS? What does Test Mode tell you? Ping me on facebook and we can diagnostic it if you want,

The MIDI issues began once the SCENE B button got fkt up

i failed to mention - this all began AFTER I had smashed SCENE B button one night after getting crazy on some amen break slicing :stuck_out_tongue:

i replaced some switches on the MM a while ago and it wasn’t too hard of a process, it requires some experience with soldering and removing parts from the board, those are not TH parts.if the switch is broken it does make things a bit easier but you would still need to pay attention to the board
if not feeling like doing it yourself, just get in touch with support…having them do it for you would most probably be the best solution :smiley:

Mine is stuck! :scream:
Apparently broken. :expressionless:
OT barely usable (if I press Play > Clear Scene for instance).

MKI. The black part below faceplate is moving, seems brocken, or unglued.

I’ll try to glue it tomorrow.


Good luck, let me know if you need help,
I’ve done it a few times.

I recommend using a good glue (not the cheapest) and putting just the smallest amount. (I aim for the smallest possible drop, one in each exposed corner)
And if the button comes completely off, be careful: inside there’s a small spring and a small ball eager to jump out. (It’s a pain to put it back, but zen-like fingers and patience will do it)

Advices are welcome, thanks!

It seems permanently stuck. It behaves as if I was holding it as soon as I use it, after reboot.

Wanted to record something tomorrow. I guess I’ll have to use scene A only. I usually use B of course. That the occasion to solder a permanent switch in order to play scenes with 2 hands!

Cyanolite (fast), slow or fast epoxy?

Yeah I’ve had something like that before.
You might feel the button wiggling a bit. And it might come off with a gentle push (after the faceplate is out, that is)

Do you have multimeter? Don’t make my mistake and start fiddling around before taking a measurement.

Measure the continuity across both scene buttons. It might not be the knob cap, it might be the switch. If you dont have continuity, there is no point gluing, it wont do anything.

If the switch is faulty, it can be cleaned, but be careful! Good luck.

Worst case scenario- like me, you’ll end up getting a new User Interface board. Which actually isnt a bad thing… makes the OT feel like new!

Thanks. Yes, I planned to test with a multimeter. As it has an engaged behavior, I think there should be continuity…

Yes, I thought about your case!

With cola flavour? :content:
Super Glue 3 in France.
Yes it’s cyaniolite. Very fast, but not the strongest.
I think fast epoxy is better. (Holding 12 mn).

Could you elaborate?
I apparently don’t have continuity between scene A and B solder points.
I don’t get why there should be continuity, not the case for other switches btw…

I have continuity between the 2 scene B solder pounts.

Edit, 3 post limitation
Thanks both, glue worked!
@phading I didn’t follow your advice correctly, too much glue, button stuck because of glue! But now it okay.
So @Microtribe could you elaborate about continuity?

To clarify, check for continuity across button A, (with button pressed) then check button B in same way.
I said check both because you knew A worked fine.

Each button has two solder points on the back of the board. Can also check continuity between the button and its associated resistor, if you need further troubleshooting.

Is it all working now?

Ah ok I misunderstood, thanks.
So yes I tested continuity for each button.
Constant for B, then glue solved it.
