Send Program Change to Your Ketron

Let’s Take a Closer Look at a Program Change from OAX to Ketron

We heard back from some of you, and we owe you more details on how a program change and how other things work. We will circle back and dig deeper under the covers for folks that want to learn more in upcoming posts and videos. In this round, we show that we can send bank and program changes from our Sonic to our Ketron SD40. If you have a question, please respond via a comment to this post, and we will try to get you an answer.

    Anyone know if the Ketron styles are compatible with Wersi styles?

    Hi Curt & Bill,
    Thank you for your suggestions I will dig a little deeper over the week end and let you know
    my findings, I have been working with midi instruments for a number of years but have
    never found anything as complicated as Wersi midi, nobody said life was easy !!
    Thanks again.

      We are here to help and will 100% get you up and running. As I’ve mentioned many times – I’ve never had the “OAS experience.” I can say that I worked MANY times with the CD / Pegasus MIDI configuration.

      It worked well and made 100% sense to us. We are not afraid to say the MIDI implementation on OAX does make my head hurt BUT I’m ever so slowly getting used to it. Is this where I say my age is showing?

      In any event, as we have said in the past – “MIDI is MIDI.” Don’t be bashful. Ask questions so not only you but others can learn and follow along as we get your configuration up and running,.

      Hey Dave – Were you able to make any progress over the weekend? If you are still stuck post your questions, and we will try to help get you up and running.

        Hi Curt,
        I managed to get the Abacus Duo to play style and auto accompaniment from the Ketron
        but only from the upper manual of the Abacus, I will explore other avenues as soon as I
        can. Thanks for your help and interest.

          That’s great Dave, sounds like you are making progress! Ask questions as needed and we will help if we can.

          HI Dave

          Follow the video here for the Ketron then on OAS, go into settings and under the General Settings block, select Midi Settings followed by the Midi output you are using for the manuals. (Man Out Ext 1 or Man Out Ext 2)
          Make sure everything is set to off and then set Lower 1 Standard to channel 2, (Touch the Lower 1 standard box till it turns red and adjust the channel with the Tempo/Data wheel) this will make the Lower 1 to constantly output on Channel 2, (The requirements for the Ketron) go back to the main screen and you are done.
          Have fun

    Hi Dave,

    Just to add to Bill’s comment, you can also find more details on the Wersi OAS external MIDI system in Chapter 2 of the Wersi HD Series Upgrade Manual, (“Setting up the MIDI and Audio Systems”).

    This contains a specific external MIDI configuration that will support your KD7 connection. It’s actually written for the connection of an external computer, but the setup at the Wersi end is the same.

    I would be tempted initially to follow the procedure in Curt’s video “Basic Wersi OAX Configuration with Ketron SD40”

    Here we set up a particular sound in the Ketron and use the Wersi just to send MIDI note on/off data to the Ketron (i.e. no Program Change codes are used to set/change the Ketron sounds). There are typically two MIDI Output Ports on OAS instruments, and each one has a block of 128 external sounds associated with it. Chapter 2 gives details on how to display these on the MIDI-Sound Programming Menu.

    Now you can load any of these external sounds into Selector 1 of the Upper Manual. If you have configured the Wersi MIDI external system in the way previously detailed in Chapter 2, this selector will be connected to MIDI channel 1. The easiest way to load an external MIDI sound is by selecting the Quickload option on the main OAS menu. Now click on the Sounds button, select either EXTERN 1 or EXTERN 2 (depending on which MIDI output you have connected the KD7 to) from the Sound Devices list, and choose any sound from the right hand sounds list. Now click on the Load button to load your selected sound into Selector1 of the upper manual. Note that the SD40 sets up MIDI channel 1 as the default channel for transmission. If your KD7 has a different default channel, you will need to change this to channel 1.

    Ensure that Selector 1 is activated and its volume is set above 0, and you should hear some sounds. If this works OK you can go back to the MIDI-Sound Programming Menu, set up some Program Change codes and follow through with Curt’s subsequent videos.

    Good Luck!

    Hi Curt,
    Your video’s on connecting the SD40 to OAX have been excellent, I thought I would use
    your information to midi my SD7 Keyboard to Wersi Abacus OAS, unfortunately I can not
    get either Instrument to talk to each other, if you or anybody can offer any help it would
    be much appreciated.

    Dave Woods.

        Dave – I’m sure we can get you up and running. The SD7 is the keyboard version of the SD40 so I understand that side of it pretty well and have the luxury of having one here so I can touch-n-feel it as we work through your issue. The article Bill mentions above has an excellent overview of the OAS MIDI side of things.

        Let’s try a very simple setup:

        Run a cable from MIDI Out1 on OAS to the MIDI In 2 (KEYB) connection on the SD7.
        On the OAS side set MIDI Out Manual Upper 1 Standard to “1”.
        On the SD7 during power-up select “Master” mode.

        That should be enough to allow you to play on the OAS upper keyboard and hear a sound on the SD7. If you don’t, move the volume drawbar slider for upper 1 on OAS all the way in and back out to ensure the volume gets set on the SD7 to something greater than “0”.

        Report back with what happens.

    if you save a sound from the Ketron to the Wersi as a user sound can you then use that sound without the Ketron being attached?

    • 05/17/2018 at 12:12

      Jim – Perhaps confusion over user sounds/voices. Both instruments can create, edit and save a “user” sounds. In this example, we created a user sound on the Wersi. That sound had MIDI commands in it that sent the needed commands from the Wersi (via MIDI Out 1) to the SD40. The commands are: Which MIDI channel to use and what bank and program change (aka voice) to select in the SD40.

      A long answer to say that yes, you still need the Ketron connected (via MIDI) to the Wersi. We are showing (at least trying to explain) that we can pick/select voices without touching the SD40. In some future videos, we will show a different way to set things up to use the touchscreen on the Ketron side vs. using the Wersi and also something on the Ketron called a registration (similar to a preset on the Wersi) to configure voices and other settings on the Ketron. And yes, we can select that Ketron Registration from the Wersi… Very powerful and interesting configuration.

      Stay tuned for more and please ask questions as we go.

    Would this same midi setup work with Tyros 5.

    • 05/17/2018 at 06:57

      Michael – As long as you can program MIDI channels along with Bank and Program Change info sent – Yes it will. I have never used a Tyros5, but I expect that it has a powerful MIDI interface that would allow that and other MIDI info to be sent.

      What I’m showing is the ability to control things from the Wersi. In some future videos, we will show the opposite where most things will be controlled on the SD40 side. No “right way” just whatever way works best for your setup and you as the player.

        Thanks Curt I thought it may work but thought I would check
