mapping output volume of say, stereo Return input to a controller pedal? Can it be done like a Fractal?

    Hello, contemplating trying a Kemper for my bass rig.


    I have had a Fractal FM3 for a bit, and just not gelling with it like I thought.


    I like the more visual/tactical vibe of the Kemper.


    But one thing the Fractal allowed me to do, that i really have grown to appreciate, is the ability to map almost anything to a controller pedal.


    I have my stereo IEM feed foming into the FM3 using input 2, and in the editor I mapped this output level to a volume pedal. Then the stereo output of the FM3 goes to my in-ear transmitter, and I can with a foot, during a song, adjust the balance of my bass, and everything else. It was easy, and simple to do. I even bought a small slider in a box that also works. I can reach over and slide a tiny slider to change how much of the band comes in to my in ears, while leaving my bass signal the exact same.


    So in doing my research, I found the Kemper video showing how you can use that return input as a stereo input, and then adjust the output volumes accordingly.


    I'd have to use the Headphone output to feed my in ear transmitter, but I should be able to adjust the level of this in ear feed right on the front of the Kemper using the menus and soft knobs. But can I assign my foot pedal to this output level of the return input?


    I hope that made sense.

    I guess, you are reffering to the parameter "Aux In >Headphones" in the Output Section which controls the mix of the aux in signal from RETURN and ALTERNATIVE IN versus the guitar/bass signal for the HEADPHONE OUT in particular. This cannot be assigned to an expression pedal. It can be controlled via NRPN. If you use a digital mixing desk for your monitor mix you might be able to use cellphone or iPAD to control the monitor mix and its volume.

    Yes, I was looking for a super easy way to adjust that level coming from my monitor IEM board. I don't want to change the volume of my bass in my in ears, just the "everything else" mix coming in to the Return/Alt In jacks. On my fractal, I assigned a footpedal to the input level of input 2 (the iem mix) and that was all I needed. So I'm just trying to figure how I might do that. It's usually while I'm playing that I want to adjust that.


    I guess I could just call up that menu item on the LCD screen and just grab a knob or whatnot.


    I'll have my new Kemper tomorrow. Quite excited.

    It would be cool if I could use that Quick knob to assign it to the Alternative Stereo input level. I got the Kemper yesterday, and while seemingly even more overwhelming than my Fractal FM3, it seems more 'fun' to edit and play with. I have begun reading all 365 pages of the manual, then the addendum. yikes.


    I just got to the Quick knob section. Have no idea if it will do what I need.


    But I thought about the stereo volume pedal actually. I have a tiny slider thing I was also using with the Fractal to adjust the level when I didn't need a floor pedal. I just set this tiny thing near my amp and could slide it up or down just like a volume pedal. Maybe I could somehow use Midi to do what I want?

    I meant Quick button, not knob. If I could hit that button and be taken directly to the input level of the aux input, I’d be set. At least I can leave that screen open while playing the first song or two and then I should be good.

    the quick button is not the solution to your problem, but once you hit the output button and navigate to page 7, where you can set the level of your aux signal, the kemper will remember that and take you directly to page 7, the next time you press the output button.

    That’s probably what I’ll do then. I normally wouldn’t normally have to touch that button on a gig so that will be my workaround. I will miss the ability to use my foot pedal to adjust it. But I don’t want to have to deal with a special foot pedal anyway. Thanks for clarification. If it had a midi code I could rig that up.

    It works as described via NRPN. You need to send at least three control change messages:


    CC 99 127 (NPRN MSB) address page for global parameters

    CC 98 34 (NRPN LSB) parameter Aux In >Headphones

    CC 119 n (NRPN value entry for simple 7-bit values) sets level


    Or you send Sysex:


    F0 00 20 33 00 00 01 00 7F 22 3F 00 F7

    example for MIDI channel 1

    the red numbers are the value MSB and LSB in hex

    00 00 would be "Off"

    7F 7F would be maximum

    3F 00 is somewhere in the middle

    Ooh, my guitarist is a midi master, he has our entire live show programmed, his patch changes, vocal processors, everything, even which triggered drum samples to load live. So I'm sure he could figure this out somehow. It would be so cool if I could plug in the controller I want to use, and somehow connect the two things in real time. That is one of the few things I found I liked with the Fractal computer editor. Without reading anything, I could figure out how to link virtually anything at all to a controller. The rest of the thing was way too complicated. But that part was dialed. I'll see if my midi wizard has any ideas on how to implement this properly.


    Thank you so much!

    I found this Boss pedal, sends any midi code it seems using an App. Can do bluetooth, wire, all at same time:


    https://www.amazon.com/BOSS-Wi…d5-4975-8bc7-93deae8f9840


    I'm assuming bluetooth is out, unless someone makes some type of BT dongle that plugs into the Kemper. But just one wire, no power as it's battery, and I might be able to control the volume of the Aux rear inputs.


    Midi experts, thoughts?

    Such MIDI bluetooth dongles exist. Check out Yamaha MD-BT01 and Quicco MI1.


    But I don't find indications, that this pedal could send complete NRPN messages nor sysex.


    Perhaps you can trick the beast using its switches to initially (after each PROFILER start) to send CC99 value 127 and CC 98 value 34. These are redundent and just need to be sent once.

    Then the expression pedal itself could be programmed to send CC 119 within the intended value range e.g. 60-127.


    For people who are just looking for a dedicated delay mix pedal, this should be sufficient .... just sending CC# 68.

    Just to make sure ... my statement was not related to the Yamaha nor Quicco dongles. These are no limiting factors.


    The BOSS wireless MIDI pedal can just send one CC when its expression pedal gets moved. So you need to find a way to send the two other CCs 99 and 98 at least once in advance to make this work as an NRPN message.

    Thanks for the clarification. I'm going to the Chicago Kemper Showroom for an hour of help. Maybe I'll tell them how nice it would be to able to assign a footswitch easier for that incoming Aux volume level. You never know!

    There is still the option to plug an analog stereo volume pedal pre RETURN and ALTERNATIVE IN. That's quite simple. And you intend to spend and dedicate a pedal anyhow.

    True. Just trying to keep all cabling to a minimum. And racked up. So IEM transmitter right in the rack with the Kemper, one single cable coming in the back from the IEM mixer, done. No extra cables coming in or out. I've actually come to terms with just using the knob on the Output page 7 screen. I have a new issue though, and just made a dedicated post about it. It is in regards to my bass being "in stereo" through the headphone jack. So for now, I have to go back to my Fractal until I can see if I can get that squared away. Playing bass in stereo is not what my brain wants to hear.
