Performances cannot be imported via USB memory stick. With Rigs and preset it's possible.

Does Michael Britt provide any hints, what his product is (PROFILEs as presets, Rigs, Performances) and what to do with it?

There is a chapter in the Main Manual:

Updates, Backups and Sharing Sounds

What's in there applies to all PROFILER models. Stage is no different.

First make sure, you have a USB stick, which is acquanted to the PROFILER,. When you plug it in the first time it creates three folders on that stick: OS Update, Backups, Shared.

Rigs to be imported need to be placed in folder Shared.

Don't know how Michael Britt delivers his packs, but assume it's a zip file container. You cannot import a zip file. You need to unzip the file container first. Rig files with extensions .krig or .kipr can be imported. These have normally a size of 5-6KB.

... but then you could also connect two Power Kabinets.

Had you compared the captured PROFILE against the Reference Amp after PROFILING? Both the virtual (Kemper Amp) and the real (Reference Amp) signal chain should sound the same. Both include the Neumann mike by the way - one virtually, one physically.

If the PROFILE is authentical and sounds horrible with a distortion pedal, the original should sound horrible with that distortion pedal as well.

There is no other software controller affecting the two sides of the stereo signal other than Panorama. There are also no hardware switches per channel. Even if we wanted to we cannot switch off one side of the MAIN OUTS and leave the other side on via software. It is not the software and not the update!

Simplify your environment: If the issue happens again, plug in headphones in both MAIN OUTPUT TS sockets. Both times you should hear a signal on the same side of your headphones. If that is the case, the PROFILER is not causing the issue.

I'm glad you identified the trouble maker!

There is a tendency to relate really any issue to the last software update ... and there is always a last software update given the fact that we are constantly enhancing the software. Since nearly 100% of issues are not update related, it is most effective to seriously investigate other options first. This is even more evident for release revisions, which have usually been tested in the field since weeks if not months.

You can assume that within one day after publishing about 1000 users have already upgraded and if you are the only one experiencing a particular significant change of sound or aborts or loss of volume .... it's probably not the update.

Vielleicht noch mal zur Verstärkung:

Du musst keine Direkt-Profile verwenden. Es funktioniert auch mit jedem Studio- oder Merged-Profil. Also praktisch mit allen Rigs, die sich im Auslieferungszustand des PROFILERs befinden.

Den KEMPER Kone mußt Du abschalten.

Bei Verwendung eines KEMPER Kone kann Monitor Cab. Off eingeschaltet sein - dann ist dessen Speaker Imprint Modus aktiviert - oder abgeschaltet sein - dann ist der lineare Modus (Full-Range) aktiviert. Wenn man irgendeine andere Gitarrenbox anschließt, muß man Monitor CAb. Off aktivieren. Und natürlich die externe Endstufe aus dem MONITOR OUT ansteuern. Dazu ist er gedacht.

Es gibt dazu ein Kapitel in Das Große Handbuch:

Umgang mit Amplifier-Profilen, Cabinet-Profilen, Endstufen und Gitarrenboxen

Just be aware, that all global settings in Rig Manager can only reflect one of those units at a time. This includes System Settings and Output Settings.

The PROFILER deactivates the cabinet module automatically, if it detects no guitar speaker, and puts the whole PROFILE into the amplifier module. This happens if you create a Direct Amp PROFILE without a guitar cabinet in the signal chain. It can also happen, if your cabinet is very linear e.g. if you create a PROFILE of a bass amplifier with a bass cabinet which is linear - more like a PA cabinet. I guess, it is a combination of your clean tone, the speaker plus the linear condenser microphone. However, the PROFILE is captured anyhow.

Yes, above and including 4 ohms.

The OS is not included in backups. Otherwise you could never use backups across software revisions. Just data and settings are included. Backups are always upward compatible. As written in the Main Manual you can share backups between Stage and other models and this worked since day one. You just need to be aware, that the hardware architecture differes in a few areas, which requires a few decisions:

The Stage has no MIDI THRU.

Its MONITOR OUT is stereo by design, while it is optionally stereo at other models.

The Stage supports two effect loops.

Its PEDAL sockets 1-4 don't match the PEDAL sockets of other models 1+2 plus Remote 3-6.

If you are using these features you might need to take a few decisions and adjust those settings, because these cannot be migrated automatically.

No, everything above 4 ohms works and the PROFILER. No setting required.

Marking a Rig as a Favorite doesn't require storing. It's just adding this attribute to the Rig. If the attribute is taken off, this doesn't mean the Rig disappears. The Rig rests within the Rig pool all the time and can always be seen with View "All Rigs" regardless if it's a Favorite or not. Therefor I doubt very much, that a Rig disappears during these exercises.

Favorites are linked to the owner name. If I mark a Rig as my Favorite and share it with you, it doesn't become your Favorite unless you mark it as your Favorite and vice verse. Make sure your owner name in the PROFILER and owner name in Rig Manager are in sync. Normally Rig MAnager suggests that. Otherwise Favorites in Rig Manager and Favorites in PROFILER are out of sync.

If you change the owner name in PROFILER and/or Rig Manager the former Favorites don't appear as Favorites anymore. Return to the original name, and the former Favorites are back as Favorites. But again, the Rigs are there all the time. Check "All Rigs".

Yes, you can, if this is just about Rigs and Performances.

But you cannot transfer global settings like Rig Button Morph and Locking. And this could make the destination device behave diffrently.

Wenn die Meldung beim Start immer erscheint, auch wenn Rig Manager gar nicht verbunden ist, und man im System_Menü sehen kann, dass die interne Uhr immer wieder auf 1.1.2010 steht, dann bitte an den Support wenden.

Have you tried with cables?

A PROFILER backup taken on an USB memory stick includes all data and settings. The operating system is not included. If your PROFILER units have the same OS, you can create a backup on PROFILER A and restore on PROFILER B and both units will be kloned. However a PROFILER C cannot be the klone of PROFILER A and PROFILER B at the same time except if PROFLER A and B are already klones.

Perhaps you can harmonize your settings amongst the two guitar players, and player 1 uses Performance 1-30 and player 2 uses Performances 50-80, so that you both could effectively share one spare unit.

Have you plugged in the MIDI cables, before you powered on the Uno4Kemper?

I shared above how CC# 50-54 work. If these get mixed with MIDI program changes . This might in 4 out of 5 cases lead to loading another Rig instead of morphing the Rig currently loaded. This is what happens, if absolute adressing and releative adressing get mixed. There is no gurarantee, that the program change loads a Rig in the same location within the bank as the following control change. Only if moth match, morphing gets triggered.

As far as I know UNO4Kemper just sticks just to control changes #50-54 in Performance Mode. First control change e..g. #52 loads Slot 3, subsequent #52 morphs this same Slot. It should do the same in Browser Mode. Perhaps there is a setting in Uno4Kemper.

The PROFILER just executes what its is supposed to execute.
