Header : F00020330000

Function : 01 - Parameter change

Ignore : 00

Parameter to change : 0050

Value : 00 01 - I guess it is something to be turned on

Closing message : F7

Howdy !!

I'm in the process of making a remote for a Kemper rack and I encounter an error on a few occasions ... this error is triggered by a sysex message as follows :

F00020330000010000500001F7

Can someone shed some light on what it is ?

Thank you guys !

If it works like the rack you have to keep the button pressed and move the pedal from min to max a couple of times and release.

You can also control your Kemper volume by sending a CC#7 by MIDI. It does not require calibration

Well, you could control more devices but they would have to have matching channels, which is not ideal.

And keep in mind that Kemper can send program changes in bank 1 only.

You may want to invest in a better floorboard (like Morningstars) or a MIDI event processor (like MIDI Solutions)

It depends on what mode you are on, if you have UI to MIDI checked or not and if you have program changes set or not.

I'm not sure for the USB port though.

In Performance mode and with UI to MIDI checked you'll have a cc#47 with a value corresponding to the Performance you are in and cc#50 to 54 for the corresponding slot.

You may have also sysex messages

Hi and welcome! Great to have more real pros to learn from! 🙂

With pleasure

Hi !

Simon (aka Simba), 39y and the last 13 as a touring backline tech.

Been working on Kempers on tour for a while.

Have a nice day !

So 2F in hexadecimal is 47

And 7F is 127.

So ... CC 47 at a value of 127 ?

47 is Performance selection. How could it be at a value 127 ?

Hi !

Using UI to MIDI I get some sysex messages from my Kemper.

I'm trying to understand what they mean and how I can use it to set up a control panel in Touch OSC.

I think I'm getting the first parts but the MSB LSB and their values are baffling me.

I looked into the MIDI doc and I'm trying to understand the example of the mix volume to 50%.

I can't cross reference what is sent.

My Kemper is sending me :

F0 002033 00 00 01 00 -- 00 2F 00 7F -- F7

If I understand correctly it is something with a single parameter change but can't figure what and how.

If someone could shine a light on this for me to build my own messages.

Thank you geeks !

Yes of course but that was not the idea unfortunately.

I really needed the Kemper to be able to send PC on banks above 1.

I really don't understand why they did not implemented this.

Hi !

I'd like to send program changes on other banks in performance mode.

I assigned each slots to send a specific program change but I have more than 25 performances.

Past the slot 3 in the perf 26, I need to be able to send pc 1 on bank 2.

Is there a way to achieve this ?

Thx

Hmmm ... maybe it solved.
Both units were not on the same firmware.
Updated the spare unit and it looks like it works.

Hi !

I dig out this post because I may run into an issue related.

I have 2 Kempers, 1 as a main and one as a backup.

The 1st one is connected to RM to edit performances.

At the end of the day, I did a backup using a thumb drive and then restored it on the spare unit.

Performances and MIDI routing are there but the input section and the gain are not.

What am I missing ?

Thx

Okay thanks.

So I guess I got mixed up with the Uno4Kemper chip.

It is a chip that allows to have back-and-forth communication using an ethercon cable like the remote but it does not involve the ''active sensing'' messages.

Do you know if there is any informations I could intercept between the remote and the profiler ?

Exporting presets and slots names would be useful.

Hello everyone !

I'm in the process of building a remote to use with Kempers and TouchOSC.

So far it works like a charm with only PC and CC.

Now I see that Touch OSC is receiving ''active sensing''.

I know that you can add a module to some pedalboards to retrieve switches states and preset/slot names.

Could someone elaborate on how this active sensing information is coded so I could try to extract useful informations from it and use it in TouchOSC ?

Thank you !

Good idea but very unpractical for several reasons :

- I know for a fact that Kemper tends to crash or freeze when using RM ... you have no idea how cautious you have to be if you don't want to have problems during the show.

- it needs to use a router and a hub to work with both the remote and the app, plus a PoE injector to power the remote : so a lot of hardware involved.

- I just want to send and read PCs ; not being able to mess with settings and other things.

The setup has to be bullet proof because as soon as there will be a mishap (and there will be) I don't want any reason for the musician to think I screwed up something.

I may have found something with Touch OSC but now I have to figure out how far I can go with it.

In an ideal world I would be able to display the presets on a text box in Touch OSC, but I don't know how to read the strings coming out the Kemper and if it sends it on MIDI anyway.

It has to be using the MIDI channels, RJ45 is reserved to the remote and only the remote (bullet-proofing and easiest way to hotswap the remote to the backup Kemper if the main one fails)

But thank you for your input mate !
Definitely something I will be testing during rehearsals.

Hi guys !

I'm still working on a remote solution that could allow me to switch presets and slots from sidestage while my musician is on stage with 1 or 2 remotes.

I know (and I'm regularly using it) that I can mirror the remote by using another remote plugged into a PoE hub.

The problem is that I can be quite far from the racks and laying an RJ45 is not always an option.

What I was having in mind is having a tablet at my desk with some MIDI control app (Android preferably) with buttons that i can use to send what I need using a WIDI device, BUT having the communication going both ways - being able to send PCs and monitor what is going on on-stage on the Kemper.

All-in-all, pretty much like having another remote but without the actual remote.

Has anyone done that already and could shade some light on what I'd need ?

I know that the CME Widi plugs are working, but what app can I use and is it possible to have the communication going both ways ?

Thank you very much !

Simba

Nice !

That is much clearer now.

Thank you very much

Best regards.

My concern was more about plugin 3 PSE (KPA 1, KPA 2 and Switch) into 2 PD (Remote 1 and Remote 2).

Is there a risk of having multiple POE sources for 1 or 2 remotes ?

What would happen if I connect 2 KPA and 2 remotes via one POE switch ?

Is there any danger of any kind for the gear ?

Your suggestion is interesting though, but if the ''main'' KPA fail the remotes won't have any control on the second KPA.

So it has to stay off for that in case failure, I have to plug it to the switch and then turn it on.

With the boot on time it is not a quick reaction process ...
