Hello GP Users:
Has anyone had a scenario the audio goes out of tune? My current rig incorporates two keyboards, a Korg Kronos LS and Arturia KeyLab MkII, Mac Pro with MOTU M4 interface. I recently migrated from NI Komplete Kontrol to the KeyLab MkII to add more drawbar access for the B-3x as well as access to other live configurations for multiple plugins. I currently have multiple plugins in use and the behavior is universal with all. Korg Triton Extreme, Roland D-50, and, NI “Noire” Piano. All of a sudden regardless of what plugin I use it is seriously out of tune. It’s not the pitch bend as I have moved the PB on both my Keylab and Korg. It appears as if there is a transpose and “Fine” tuning knob in place. The tuning follows regardless of what Rackspace I select so it isn’t VST-centric. Suggestions?
Strange…
Might something got mapped to PB?
Can you show us >Windows >Show MIDI Assignments (take a print screen)
I was experimenting with Gig Performer 3 Tutorial | Building Versatile Keyboard Patches which would make sense for the screen shots
?? Can you please explain a bit better?
I don’t know anything about your environment but if the pitch is off by about 1 semitone then most likely something on your system is running or trying to run at a different sample rate (maybe you are running two hosts?) as that can be one possibility
At first I thought it may be a remnant from sequencing days when pitch bend ended mid-bend thus the out-of-tune - semitone-off sound. I have been using Digital Performer in live situations for years and this crept up from time to time. In the Video noted above Brett Pontecorvo describes creating an on-off script to create a more streamlined set.
Thanks, however, everything is running a 48K and I’m only running Gig Performer 4.
Are you by any chance using a NanoPad with your Kronos? I have had this where on some Programs and Combis, the touch pad on the NanoPad is mapped to pitch bend and accidentally brushing a finger on the XY touch pad causes a pitch-bend event to be transmitted and since it’s not a spring loaded physical controller, it never returns to the zero point. This one has caught me out a few times on my Kronos.
How did you evaluate that you are off tune, by ear? Did it already worked properly ? Do you have the opportunity to use a plugin with standalone version ? (for not using GP for testing purposes).
Hello David-San
My Korg Kronos is live, playing a Rhodes Patch at the same time and I can hear it is out of tune. When I switch to another rack space, (Korg Triton Extreme VST to Roland D-50 VST for example), the tuning remains the same. Originally I thought it was a bug with the Triton.

Not using a NanoPad however the Keylab MKII is new to the mix and perhaps one default pad or preset has something screwy. (I haven’t programmed anything on this controller as yet. Worth a look!
You didn’t tell us at all if it worked in tune before ?
To find out the culprit, the idea is to start from a few very basic configurations.
- Try alternatively with the internal MBP audio rather than the MOTU M4, does the issue remain?
- Try with a standalone plugin, does the issue remain?
- Try from scratch with a new gig file and add only one plugin, does the issue remain? (then do the test again with another plugin… some Roland plugin had a similar bug)
- Try with only one keyboard controller connected, does the issue remain? (then change the keyboard controller and do the test again) => you can also try it without MIDI controller by playing the virtual keyboard of a MIDI in block plugin window.
It looks like the culprit was something in my setup of ON/OFF switch as noted in the attached video. I deleted this Rackspace and recreated going directly into the Triton from KL61MKII and tuning issue went away. Perhaps something changed between version 3 and version four. Everything back to normal.
Thanks all!
But unfortunately, the lessons learned from this issue are quite poor. I like when the reasons that made an issue occur are clearly identified. 
Don’t feel bad. I had the same experience with another VST host and it about drove me insane. Tech support was baffled. I switched to GP, and love it, but yeah - mystery pitch/tuning issues can happen
I just have. I was playing outside under a semi cloudy sky and my Surface Pro 8 got a bit hot and the pitch on my auto bass had altered. I pretty sure it was the suns heat causing this. I’ve now bought a small sports umbrella with a table mount for when I’m outside next time.
I do not see how heat could cause the pitch to change. Something else must be going on.
Who knows, if the CPU was in throttling mode or reduced its power/frequency in any way (parked cores), funky things may happen.
The other things might maybe cause issues (although the sample rate does not derive from the cpu frequency, I hope), but parking cores, just means the OS is not going to schedule anything to those cores, so I don’t expect parking to be an issue (parking is normally switched on and rather extensively used by Windows, I recently discovered).
