Kemper with Fractal FX8 - Midi Issues

  • I have set up my new Fractal Audio FX8 to work as an effects processor for the Kemper Profiler. I had abandoned my full Axe-FX rig maybe a year ago in favor of the amplifier tones available in the Kemper. That was a correct decision. That said, the effects in Kemper are adequate but not even close those produced in the FX8. The two rigs in tandem are epic and better than either company had achieved in their own systems. I believe this is the current rig to beat.


    Now I am on to crafting the rig MIDI control. I have setup the FX8 using the 4 cable method so that I can place effects before the Kemper preamp or after. This works perfectly. My control intent is to have the effects setup on the FX8 so that when I change a performance on my Kemper Remote, it automatically it sends a Program Change (PC) change to the FX which changes the effects on the FX8. Plugged a MIDI cable into MIDI OUT on the Kemper. Set the Kemper to send MIDI on the "MIDI OUT" output. Set my FX8 to receive MIDI on Channel 2. Then grabbed the midi listing for the FX8 designating what each Midi Program number would be for each setting. (Note that the Kemper starts MIDI Program Change Numbers with "1" and FX8 Starts with "0" which means there is always an offset). I am sure this can be corrected in either system but I have not done so thus far. I then went into the Kemper Performance Rig Settings and went to set the Midi output for channel "2" and made the appropriate FX8 Program Change Choice (+1 for the offset) to drive the FX8 changes. I probably went through a dozen performances and set this up for each respective slot as well.


    Ready to rock, right? Almost - the program changes seem to work to perfection on about half of the rigs. The other half seem to change nothing on the FX8. As if the FX8 is getting no MIDI call at all on these performances? I spent a couple of hours verifying that each performance was set up using the same protocol but still the same channels worked perfectly while others drove no change. Any ideas what would drive this erratic behavior? Is the Kemper perhaps sending a conflicting MIDI signal of which I am unaware? Would deeply appreciate any insight into the problem! I am so close to my dream system, so close! ;( THANKS

  • hey there.... I have the same rig (MK II version)


    question.... you say "the other half seem to change nothing on the FX8"...... what effect are you trying to "Change" on the FX8 via/thru midi from the the kemper?


    now i will say I'm sicker than a dog and on med's... so maybe I'm not reading this right lol..... but I use the FX8 as a Footcontroller AND effects in the loop of the Kemper with only changing amps/proformance via "Scenes"

  • I am set up in reverse I guess. I am using the Kemper Remote to trigger changes in the Kemper profiler which in turn sends a MIDI Program Change Message to the FX8 to select a preset. My reason for this scheme was to retain the useful ability in the Kemper of arranging Performances for each specific gig. My scheme does require that both the FX8 and the Remote are hauled around. Your approach is probably cleaner. If I can't get this arrangement to work I might switch to your approach. I am probably using too many distinct presets for gigs anyway. Hope you feel better!
