OAX / Ketron / MIDI Fun – Part 1 of ??

Over the past year-ish, we have posted on and off about using MIDI with OAX. Some of our first MIDI related posts were when we connected up our Roland Integra-7 Sound Module to OAX. Missed that post? You can find it here. A few months after that we started to play around with VST’s hosted on OAX. Under the covers that is all based on MIDI data flowing between OAX and whatever VST you happen to install. Here’s one video on that topic. We did five or six videos on working with OAX and VST’s.

Next? Why not try to work out the needed MIDI config to use a Ketron SD40 with OAX? And just to make it interesting we are doing that with Ross Monk, who some of you know. Ross is located in New Zealand and is 18 hours ahead of our time zone. So, between our schedule, Ross’s schedule and the 18 hour time difference it takes a few days going back-n-forth to make any progress.

Over the past week or two Ross and I have traded a few emails. I sent a note to Ketron asking if they would be willing to ship us a demo unit for a week or two. It would be much easier to work things out if we could have a unit connected to our Sonic. Unfortunately, they never responded so Ross and I are doing the next best thing. We are working using video phone calls via Skype so I can see his organ and the Ketron while we figure things out.

Here’s what we know at this point:

The SD40 has a number of sounds that you can play either independently or mixed with OAX (or if you are really brave, with VST sounds) but it also has an entire section dedicated to automatic accompaniments called Styles (basically the same idea as the Style section in OAX).

Each Style has:

  • Two tracks for drums and percussions on Midi channels 9 and 10.
  • One Bass track on Midi channel 5.
  • Five harmonic tracks that function on Midi channels 6,7,8,11,12.
  • Two “Real Time” tracks, namely Lower 1 and Lower 2 that are assigned to the left split of the keyboard, which function on Midi channels 3 and 4.
  • One LEAD track that functions on the Upper section, namely on the right of the keyboard Split.

Read that one more time and you will say — Hmm, not exactly the way OAX (or OAS) MIDI channels are configured. And that is exactly what we intend to work out.

Notice this post is titled Part 1 of ??. You can fill in ?? with your guess of how many posts we end up doing as we work out the needed config. Post your guess in the comments section.

  1. Let me ask Ross to chime in if I missed anything in the basic setup of this discussion.
  2. If anyone following along has a Ketron, and has already figured out the needed configuration on both OAX (or OAS) and the Ketron, we would love to have you share your configurations.
  3. Stay tuned as we work of the details and get this working.
  4. While you may never own a Ketron, I’m hoping the discussion amongst all of us will enable everyone to get a little smarter and you will be able to use that knowledge with other MIDI related configurations in the future.

OK, It’s your turn. Chime in using the comments section! 🙂
