tuning calibration
« on: July 28, 2013, 02:02:35 pm »
Fired up the minibrute last night to find the tuning out over the full range of octaves. When i originally got the minibrute the tuning was stable after warm up and i had the tune knob set at 11 o'clock. Only the top octave would be slightly sharp.
 Now i find i have to tune the brute slightly everytime i hit the transpose buttons and i now have the tuning knob mainly  at 9 o'clock.
 How easy is it to calibrate the tuning and do i need to use a plastic, rather than metal, 2mm screwdriver just to eliminate the issue of shorting out the brute.
 One last thing it has been extremely hot down here in the south of england and just wondered if this could be factor in the problem im having.

 Any help will be greatly appreciated.

It's better with a plastic screwdriver; but take care and go it very very slowly with settings.

Hi tertior,
 Thanks for the reply. Which way do I turn the calibration screw. Does it matter if the tuning is flat or sharp to determine the way you turn the screw?

Hmmm, It is better to ask Bruno  of Arturia because it can also be a drift in the oscillator.
Don't touch it and speak with Bruno.

they are availabe from this ebay seller and from reichelt[link removed] - and probably from just any electronics store?

[post edited for better clarity]

[additional edit: reichelt link removed, as apparently the item it linked to doesn't fit - sorry about that]

You could just whittle a Knex rod or the like into a screwdriver shape.  That's what I do.  Easy enough.

That's ok but what if you suffer from a nervous disposition! Bit like playing operation!  :o

well like i said, you can find them both on ebay and at reichelt.
both the links i provided above will lead you to a set of plastic 'adjustment tools'.

sure thing. edited my earlier post for better clarity, btw. it originally looked as if i was only linking to ebay and reichelt, not to the items you guys were looking for. :)

I check out reichelt but found it will be too expensive to send them to England. Just bought a set from Ebay for 5. I'm happy with that  ;)

Thanks for link Bartleby.
