I have a Studiologic SL-880 and a problem too with it.


When I hit a key on the master keyboard, two different sounds speak in a same time. Like it be detuned. I use it with a Sennheizer Midi controller, not else. How can I set it back to the standard status?

  • Do you use it stand alone or with another keyboard or PC? Can you give more detail on your connections and routing? Jan 17 '15 at 14:35

  • Which software you use to play sounds? There may be a problem in MIDI routing. Jan 21 '15 at 21:17
  • I don't use any software, because the Midi controller doesn't use any software. Jan 22 '15 at 0:30

The problem sounds like the MIDI routing is going into a feedback loop. This means the sampler device getting signals from Studiologic, is sending the MIDI data back to the Studiologic. And Studiologic doesn't understand that it is its own signal returning back but thinks that the MIDI signal is coming from another controller. Therefore Studiologic passes it directly to the sampler, which causes a feedback loop. Since this happens very rapidly, you hear a detuned sound because same sample is triggered more than once with very close intervals.

The channel on the sampler should only accept MIDI signals, not send any MIDI signals back.

For example this is how it's done in Nuendo 4 channel settings. MIDI-in of the instrument channel is accepting signals from Scarlett but not sending any:
