I haven't been able to find a way to calibrate anything. Does the auto tune function help? "Shift + Exit"

I have different issues with Osc 1. It just doesn't sound on all key presses. I get a dull thump and the scope shows a flat line once every 3 or 4 key presses. Been keeping it turned down until I exchange it.

Seems quiet in this Prologue forum. I expected more noise over this synth and especially more info by now.

Yeah the manual tuning didn't help. So i sent it back. I dont want to gamble on a new one at this point so i just got a Prophet 6.

I've noticed the same issue

I still have the old sw version and I've to run the upgrade, do you think that the V1.1 will solve the problem?

I think I've solved the problem

1st I upgrades the system

Then I performed the panel and voice update, everything is explained in the doc

Panel update: restart the prologue pressing 6 shift and exit button, wait few seconds until you read update complete

Voice update: restart the prologue pressing 5 exit and start

I've done the full update and the voices issues are still here, now word from korg if this is hardware or software related, I've send my prologue back for an exchange, seriously gutted this synth is a pain in the ass

I hope Korg does not make the same mistake they did at the time of the rh1 keyboard on Kronos

Pls Korg say something

On my prologue unit the problem seems to be solved, but I want to better check
