MIDI Configuration for 2 Keyboards and Multiple Sounds

SD40 MIDI Configuration

In the last video, we showed a basic MIDI configuration that allowed us to play our SD40 using the upper keyboard of our Sonic. During the next couple of videos, we are going to show you some changes to the MIDI setup on both the SD40 and our Sonic that will enable us to play on both the upper and lower keyboard and also turn on and off multiple sounds (voices) on the SD40. In part 1 we look at setting additional MIDI channels up on the Ketron SD40.

      Yep – I got it and sent you a picture back showing a different MIDI config on the Ketron side from what you currently have configured.

      For those following along the issue is Klaas currently doesn’t have MIDI channel 12 and 13 turned on to receive data on the Ketron side.

    Hi Curt,

    I follow your nice video tutorial but i have a little problem. On the upper keyboard on my Wersi Sonic i have STD Midi Ext1 on channel 1, Std Midi Ext 1 on Midi channel 12 and STDMidi ext 1 on Midi channel 13.
    On the Lower keyboard Std Midi ext on Midi Channel 2.
    I have sound on the upper keyboard on STD MIDI EXT 1 on channel 1 en on the Lower keyboard the SD 40 Styles sounds and chord changes on channel 2.

      Hi Klass – Sounds like you are making great progress! Can you tell me what you have configured on the Ketron side? Which Ketron are you working with? I’m assuming that’s what you are connected to from your Wersi?

      Make sure you are connected to MIDI In2 (Keyb) on the Ketron side. Also, let’s check on the MIDI channel configuration on the Ketron:

      Touch the “Menu” button
      Touch the “MIDI” Icon
      Touch “Accordion Style and Voice”
      Touch “Arranger Keyboard”
      Touch “RX”
      What MIDI Channels are active on that screen?
