If you look carefully at the section headers you'll see the Midi Ox/Midi Yoke section is entitled "Hardware Synth + Hardware Ports". This is not for using a hardware synth together with soft synths as you indicated in the original post. It is for those that want to send midi data to multiple hardware ports (say a combination of synths, light controllers and harmonizers).

The section you want is "Software Synth + Hardware Ports", sub-section "Melody to Hardware Device". Note that melody could refer to any BiaB track.

In that section are a number of different configurations that depend on what you want to do. In the OP you stated that you simply want to send data to your Ketron. This is the simplest configuration. You do NOT need MidiOx/MidiYoke to do this (although they are useful for diagnostics).

The pertinent statement is this.

"First, if you have a hardware synth available... ...then you can use a one step procedure. Put a copy of MidiRedirector on the melody (or other) track you wish to send to your hardware device. Choose the port which has your device(s) connected. Now, when you play BiaB, the melody will go to your hardware device and synth."


I hope this helps.
