Mix, Match and Splits

Mix, Match and Split – OAX and Ketron Fun!

This video is all about having some fun and letting you think about the possibilities when you jump into the world of connecting MIDI-capable devices. Our inbox is full as we have received an email from many of you. Along with that we are watching comments on our blog and understand some of you are struggling with this concept. We are looking into ways to help you understand all of it better and help you get up and running.

In this example, we mix, match and split sounds from a Ketron SD40 along with sounds from our Wersi OAX Sonic. Honest, we haven’t even scratched the surface of what is possible when you start to combine these two instruments.

Hang in there while we all learn this together. Reach out to us for help in your journey. We are here to help get you get online and up and running with Ketron, Wersi, Roland and other popular keyboard instruments.

We welcome your questions and comments. If you already own a Ketron or Wersi product – Chime in and tell us how you are using them. If you have questions, please ask. If we don’t know the answer, we will dig deeper and get you an answer.

    Hi Curt,

    I’m very much enjoying your Ketron videos. I agree with Dave when he says that the Wersi MIDI system seems somewhat complicated. Wersi have never been that good at producing good quality English documentation, and when they do it’s usually in the form of that employed by a typical User Manual, i.e. predominantly just a list of all the features and controls. We all know the sort of thing, “The Subharmonic Deflanging Equaliser Control – This controls the Subharmonic Deflanging Equaliser”. Well great. But what we really want to know is what is it, what does it do, and where and when would we use it. Your videos are excellent in describing all of this.

    I have a couple of questions relating to the mixing of OAX and Ketron sounds, specifically to the allocation of MIDI channels. Let’s consider a couple of likely scenarios.

    1) Ketron sounds mixed with OAX sounds.
    In this scenario we have placed an OAX sound in the upper manual selector of a total preset, and the OAX has allocated it say MIDI channel 1. Now let’s add a previously created Ketron user sound which has also been assigned the same MIDI channel 1. What would the system do?

    a) Throw a hissy fit, fling its toys out of the pram and crash.
    b) Display an error message saying that this is verboten.
    c) Recognise that one sound is on an internal MIDI channel, the other on an external MIDI channel and allow the combination.
    d) Something other than the above.

    If this is a problem, one possible solution would be to place the Ketron sounds in the selector first, and then add the OAX sounds. In this way the OAX should know which MIDI channels had already been allocated and assign the next free MIDI channel to the OAX sound.

    2) Ketron sounds mixed with other Ketron sounds.
    In this scenario we have placed a previously created Ketron user sound with an allocated MIDI channel of say 5 in the upper manual selector of a total preset, and are adding a second previously created Ketron user sound which also has an allocated MIDI channel of 5. The Ketron has hundreds of sounds available and we only have 16 MIDI channels for allocation, so there’s bound to be some channel duplication. Would we get the same response from the system as suggested above?

    If this is a problem, one possible solution would be to change the MIDI channel of one of the Ketron sounds to another number. Whilst possible, it wouldn’t be advisable to do this since the sound might be in use elsewhere in another total preset, and in fixing one MIDI channel clash we might very well create another. A better solution would be to create a duplicate of one of the sounds specifically for this total preset, but with a different MIDI channel allocated.

    One possible general solution to both scenarios might to use the dynamic allocation mode for our Ketron sounds (the sys channel option). I think I saw that this was possible in one of your earlier videos. Now MIDI channel allocation of both OAX and Ketron sounds is handled by the OAX, so no channel clashes would occur. The problem with this approach would be if the receiving device required its MIDI transmissions to be on a defined MIDI channel. I don’t know how the Ketron would cope with this, but software such as Hauptwerk, VB3 etc. requires transmission on a fixed channel so it wouldn’t work in the generality.

    Perhaps you could try out the two scenarios Curt, and let us know your findings and thoughts. My interest is purely academic you understand, the OAS deploys a different MIDI channel allocation system, and whilst this is not as flexible as that used by the OAX, it’s completely foolproof in this regard, so these kind of scenarios don’t occur!

      Hi Jeff
      No. 1 should be the same as OAS (C) as it is the most common.
      No.2 should be interesting to see if it’s the same as OAS (When you try and use the styles/midi on the same port as the sounds) or some other way. (Ideally it should not allow you to create this type of configuration without a warning) NOTE: a lot of Midi equipment can accept more than 16 channels with a code being sent with the sound to tell it to use the additional channels. (I believe the Ketron equipment supports 32 (But don’t quote me on that) but does OAX)
