I’ve been a happy owner of Polybrute 12 for about a month now. The synth is amazing but I have two problems with it.
Problem no. 1 - after entering Sleep mode, the synthesizer behaves randomly: the mode change diodes always flash, but the screen is sometimes on and sometimes off. A bigger problem is that after waking up from playing on the keyboard, the screen doesn’t always turn on. In such a situation, only pressing a button or turning a potentiometer helps. This happens quite often.
Problem no. 2 - sometimes, after switching to the arpeggiator or sequencer preset, the sound is triggered immediately without touching the keyboard. After repeating the operation, the synthesizer behaves normally, i.e. it waits for sounds to be played on the keyboard.
Does anyone else have this problem with PB12 ? Is this normal behavior ?
Thank you in advance for your help and best regards.
Just for the record: I noticed the second problem (arp is triggered immediately without playing a note) also quite a few times. How can we report this as a bug?
At the top of this page there’s a “_SUPPORT” link. Click it, scroll to the bottom, click “Ask for help”, scroll down, click “Ask for technical support”.
Before writing to the Arturia Support, it would be really nice if somebody here could try to reproduce the arpeggiator problem we have discussed above.
It seems that the problem occurs only when specific keys have been played just before the arpeggiator is activated.
Could anybody please try this:
Load the init patch or reset the current patch to the initial state
Press and release the middle “D” key (the “D” just below the center marker of the ribbon)
Activate the arpeggiator
On my Polybrute 12, the arpeggiator starts playing a pattern with the “D” key even though no key is pressed.
There seem to be a few keys that activate this behavior, like all lower “D” keys but also some “Bb” keys. I have not tested this for each key.
MY PB is connected to an MPC Live via 5 pin Din. It doesn’t matter what input MIDI channel I set the PB to, it will trigger as if it was set to (receive) ALL. The several other keyboards in the chain are functioning properly and respond to their corresponding MIDI channels. I’m pretty sure there’s not an issue with my setup.
Am I missing a setting on the PB or is this a bug?
I’ve never had a problem with that on any of my Brutes. Tried the PB just now as a sanity check and encountered no problems - the MIDI settings does what you’d expect, the input channel setting is obeyed.
If this persists, make sure there’s no mixup with “Input Channel” vs “Input Channel Lower”, then perhaps try a “Settings/Misc/Factory Reset” as the simplest possible potential ‘cure’.
