odd pitch behaviour using cv/gate with the microbrute
« on: April 04, 2014, 03:14:27 pm »
Hello Arturia team,

When I control the microbrute with the beatsteps cv/gate signals the pitch is transposed 3 octaves up.
When controlling it via midi everything works fine. Can you tell me what's the problem and how to solve it?

Today I also had some other trouble with this setup (using midi). This time i think it's the microbrute, but I'm not sure:
When there was no sequence running and I tried to start the sequence while I was adjusting the pitch of one step, the microbrute would hang up on this tone. All notes off command didn't work, i had to reboot it.

Thanks,
Chris

Even if the Beatsteps CV out is only connected to the Microbrutes pitch input and no sequence is running everything i play on the keyboard is transposed severals octaves up!

Does the MicroBrute have some settings for how it will be controlled by CV?
I know that when sending CV via my Elektron A4 to my Moog SlimPhatty I had to correct the voltage in order to get it to scale correct. Might be the same with the Micro Brute

@vegradd:
According to some videos I saw, it should work without voltage correction.

I think I was able to evaluate the problem:
Apparently there is a constant voltage being sent out of the CV output. Even if no sequence is running.
When a sequence is running, the correct control voltages are added to this constant voltage, which causes the higher pitch.

Hi just bought the beatstep with the ideal of a running a moog slim phatty  with the cv /gate option so I can run something else in control mode thing is I to am getting the same problem its outputting at a to high pitch than I want works fine with midi ive read different synths require different voltage is the moog slim phatty one of them and is that it do I have to use the midi option shame really I looked forward to running 3 things cv for my moog midi for my korg x50 and usb for pc can anybody help please....

Have you tried turning the autotune of the Moog off?

hi m8 thanks for the reply I tried with autotune on/off from what I can gather its beacause the aturia beatstep is outputting  a certain voltage and so is the moog s/p but different so the difference is being the higher octave works fine in midi just wish I had researched this before  purchase if they implement some kind of tie like reason 7 matrix I will be happy to run in midi if no tie perhaps regretting purchase.

This might seem an odd question but - what do you mean CV pitch IN on the microbrute? As far as I can tell there is only pitch OUT. There is however gate in.

The pitch input is part of the mod-matrix!

I can confirm that the basic CV output is too high and the gate is too low… Tried it on a Minimoog and I have to have all 3 range switches  set to 32'. Even then, it's still too high and I'm having to feed it through my modulars CV adder (along with a -3V source) to reduce the output. Not ideal but it works. Also, the gate won't trigger my ARP… That has to be processed via the 2600's amp to get it to a decent level

Hoping Arturia can fix this via a firmware update.

Oh right!

I tried that too but unfortunately I'm having the same problem as everyone else. Weird that Arturia's products work terribly together.

Hello,
I got the same problem hooking up my Minibrute with the Beatstep.
It first didn't work over Midi. and it's pitching 3 octaves higher with the CV IN.
And it even makes sound while the Minibrute Master Volume knob ist turned down. Like a kind of selfoscillating sound.

I don't know, why Arturia products didn't match up this time....

Somebody got a solution yet?

Hurray iam not on my own wasn't to sure if it was me only got a moog slim phatty and use it by usb so kinda new to this < bar using reason>
