Filter mode knob doesn't work
« on: October 21, 2013, 05:17:58 am »
Hello folks,
My minibrute was doing all good, but yesterday suddenly the Filter mode knob (LP/BP/HP/NOTCH) behaviors not working.
LP/BP/HP position, there will be no sound.
only Notch filter mode the sound would be.
Please help me. I tried fresh firmware update (1.0.21 -> 1.0.21) but it was no good.
thanks in advance.

take a picture of your front panel and upload it.

it sounds like you have a problem with your patch, NOT with your hardware.

but you never know

take a picture and upload it...it's 99% likely that it's user error.

this is not an issue that has been widely reported...and when stuff like it has been mentioned it turns out to be a simple fix based on the patch , etc.

just take a pic and upload it...

Please right-click to save the pic.

This is the patch I've tried.

It would sound perfectly at 'Notch' filter position, but on LP-BP-HP mode, it produces nothing.

Two envelope LEDs are flashing, so I found that my internal keyboards cable connection is OK.

please help..

sslneve,

I tried your patch. (Sounds great!)

Filter mode knob works as expected and changes the sound.

If you were to start with a totally simple patch - the saw with no filter envelope, 50% cutoff, 50% res - and change the filter mode, do you hear anything on LP, DP, HP? Or is only notch working on all patches?

When you say you get nothing, is it total silence? Can you hear the amp clicking, any of the oscillators?

The mode knob is not not something that firmware should affect - I believe the modes are analog, hardwired to the selector knob.

I think if you've tried everything and only Notch produces sound, you need to get a support ticket started.

Thank you for kind support!
I've tried your basic patch. The result was same. No sound on LP-BP-HP position.
And I found that it is not total silence. The led on my analog mixer was lit a little bit (very small signal) when I heard nothing with my ears.
I think this is an obvious hardware issue.
I'm aware of the keyboard problem (which can be solved by re-connect internal cable), but this issue makes me very frustrated..
Actually I can't contact any authorized technician on my location..
More ideas on this? I really wanna sort this out..
So desperate..

If you've already opened the MiniBrute up and tightened cables, I'm not sure if there's anything else user-servicable.

The filter mode knob has 4 detents (the click where the filter modes made contact) and dead space between them, so you can't select 2 modes at the same time.

When the mode knob is forced into dead space between filter types, the audio path is normally bypassed. I can hear faint clicking, but no real audio.

Is it possible your mode knob is somehow damaged or shorted? Can you look at the PCB near the mode knob for anything visually damaged? (Like a keyboard weight that got into the circuit area, or corrosion?)

Someone with a soldering iron and a clue please chime in!

T3k, thanks again.
I confirmed that Filter knob itself is totally detented and cannot be on 'dead' position naturally..
I didn't drop the unit to the ground, and of course there was no shock or impact.
Strange thing is, my Minibrute was so fresh and rock solid at first..
Maybe I have to open the bottom and look into the circuit board which you pointed. What a disaster..
Feeling so much pain..

hey sorry i didn't reply sooner.

yeah there's nothing wrong with that patch...

just another case of faulty minibrute. and i haven't heard great things about sending arturia units in for repairs recently....doesn't look good / idk what to say.
