HI!!! I WOULD LIKE TO KNOW IF THERE IS A WAY TO START MINIMOOG OS, AWAYS IN MULTI TRIGGER MODE, I DONT USE SINGLE TRIGGER, AND I DONT WANT ANYMORE PUSH THE TOP TWO KEYS, EVERYTIME THAT I POWER UP. THANKS FRIENDS…
Hello Alex, please unlock your CAPITAL key on the keyboard first.
Writting in upper case is normally considered bad behavior on forums. Its the equivalent to shouting.
YES, PRESS CAPS LOCK, THAT FIX YOUR TRIGGERING PROBLEM, AND WHY DON’T YOU ENGLISH BETTER?
Not too harsh… 
From page 30 of the User Manual:
Keyboard Modes
The Voyager OS keyboard priority is LAST NOTE, and the trigger mode is LEGATO. ‘Last Note’ means that each new note on the keyboard generates a new pitch CV. ‘Legato’ means that as long as any combination of notes on the keyboard is held down, the keyboard Gate signal is high (in other words, Single Trigger
mode). The Voyager OS can also be configured for Multi Trigger mode. ‘Multi Trigger’ means that each new note played on the keyboard re-triggers the Gate. To place the Voyager OS in Multi Trigger mode, simply hold down the top two keys of the keyboard as the unit is powered up. The Voyager will revert to Single Trigger mode the next time the unit is powered up unless the top two keys of the keyboard are held down.
It appears that the setting is not saved, so it looks like what you’re asking for is not possible on the Voyager OS.

Hey guys don’t be dicks. Help him out if you can, good job suggesting how not to offend anyone with a caps lock key (…) 
, and carry on. So he’s new and didn’t sound like a dictionary … so what? This is just a forum anyway…
OP… sorry, can’t help you with your synth. Seems like mayidunk answered your question though. Welcome to the forum.

I was just pointing out how helpful Till’s post was.
