Already own a rack and I love it. I was contemplating a second Kemper rack. Now I want a Stage. The two combined will be formidable.

I am hoping that Stage can operate as a slave as well as a master when connecting via S/PDIF.

My UA Apollos can operate as slaves, so I can connect a single Kemper via S/PDIF. But two Kempers can't connect to two Apollos via S/PDIF because both need to be set as masters.

This also makes connecting two Kemper Rack or Toasters via S/PDIF a problem.

If the Stage could operate as a slave, these issues would be resolved.

I could connect the rack and Stage in series without an extra conversion step to create a monster. And I could connect both my Rack and a Stage to my two Apollos via S/PDIF.

That would give me an external loop before the amp stack for wahs, overdrives, fuzz, etc., and two loops for time based effects post amp stack.

Or I could mix preamp only rigs in the rack with power amp only rigs in the Stage.

Agreed!



SPDIF Input is useless if:

A:  The target receiving SPDIF device can not be set as Audio Slave, and can NOT extract wordclock from the received SPDIF data stream     

or

B: The Target receiving device lacks a built in real time SPDIF Sample Rate Converter to allow external SPDIF streams to be converted to accommodate the internal Master Clock of the target device.
Pro gear often includes separate Wordclock BNC I/O jacks

Luckily this has SPDIF IO

Allows VG99 to perform Guitar Modeling , then connect to Kemper Stage via SPDIF ( as many already do today with VG-99 and Helix

It would work with the VG99, but I think the Kemper lacks the routing flexibility to really make full use of the potential of the VG99.

In my setup with VG99 and Helix, I have three sound sources: channel A, channel B and the direct signal from the guitar., which I like to combine and layer in many ways building my patches.

For me the ideal Kemper would be either a new model with multiple amps and much more routing options, or a very small profile player, that is midi controllable, that I could add to one of the loops of the Helix.

I do think Kemper will sell many of the stage units, as it will appeal to many users. But for my needs it does not fit the bill.

Could you use an external clock to overcome the limitation of only operating as a master?

So for example, you have 2 Kempers which only operate as master. You set both up to operate at 48 khz and as master with S/PDIF sources.

Now add an external clock that can operate as a master or a slave. Connect each of the Kempers to the external clock with each connection having the clock operate as a slave. Could the clock resolve any differences internally between each of the S/PDIF streams so that S/PDIF could be passed between the two Kempers?

Kemper 1: Set as master @ 48 kHz (S/PDIF out) --> external clock

Kemper 2: Set as master @ 48 kHz (S/PDIF out) --> same external clock

Clock resolves differences and sends each Kemper S/PDIF even though it is operating as master.

Potentially, the new software that is coming might allow a Kemper Rack or Toaster to use the S/PDIF I/O as an external loop. There are two external hardware loops on the Stage; one on Toaster and Rack.

Note that loop 1 on the Stage can also be used as an extra external mono output and/or and external stereo input.

Since Kemper has confirmed that any profile is fully compatible with any model of KPA, there will need to be a way to use a profile created with the two loops on the Stage with a Toaster or Rack. So the Rack and Toaster will have to be able to add the functionality of a second hardware loop to the profile. I would think that a firmware update might allow the Rack or Toaster to use some I/O as a second loop.

All Kempers are MIDI controllable. That's how my RJM MMGT10 controls my Kemper Rack.

Quoting G-String (Kemper rep) on the Kemper forum:

    Strange that they don't mention the editor at all in the marketing material?

you over interpret here.


before this entire discussion drags on and on, let me fill everybody in on a couple of details. the majority of our engineers is on holiday right now. we've hoped to get things done before the holiday season started but as you can see, we didn't manage. at the same time, we don't want to release a beta version of something as big as the Rig Manager Editor and have no engineers at our disposal. i'm sure you'll understand that. so, when everybody is back, we'll finish things up and you'll get a beta. until then, enjoy the summer, enjoy your guitar. it's the most beautiful time of the year ...

the VG-99 replacement = Just as a Hex PU and use one Kemper for each string !

I'm updating firmware on my Kemper Toaster + Kemper Remote floor controller

This is the very first time things went smoothly, mostly because prior update attempts I would

Step 1 ) Install the KAOS.BIN firmware update into root directory of a 32GB USB Drive on my PC,

Step 2) With Kemper Powered OFF, Install the USB Drive into rear USB Host post on Kemper Toaster.

Step 3) Power ON the Kemper


^^ Above procedure never worked

Despite reading the official Kemper update procedure in prior manuals , I only recently discovered the proper method is:

Step 2 ) insert the USB drive from Step #1  - WHILE the Kemper is ALREADY POWERED ON!

Step 3 )  Follow the LCD prompts and press the Button above the Kemper LCD to Initiate the Firmware update procedure.

Finally the update procedure works

I also have the Kemer Remote connected to toaster via Ethernet, and its firmware also updated too  - and now the toaster in System settings can adjust the LCD contrast and brightness of the Remote floor controller too. 



thanks to the video below !

My Kemper-GR55 family

 

Gr55 is in a drawer below Kemper Toaster



The Expression pedals, for the Stage, are on a hinged shelf on top of the GR55

Still haven't figured out how to make pictures larger ???

Putting two expression pedals on top of the GR55 is actually quite clever. Are there hinges at the back?

Yes the shelf is hinged. I made both pedal boards out of Ultra-light plywood. So the board adds very little weight

I only use the espression and control pedal on the GR55 so it works out well. I'm making a plastic cover for the other GR pedals, so I don't accidently turn on the looper

Each pedal board has a mount for a mic stand pole, so it's pretty self contained

I must say, the Kemper effects are extraordinary.

Acoustic Simulator close to release. Stunning sound!

Have to admit . This sounds pretty convincing
