The SD2 headphone jack is a stereo (mini TRS) output as well.

If you insert a mono plug into the headphone jack, you will only get one channel. But the other channel output will be shorted out by the Sleeve of the mono plug.

There is really no mono output on the SD2. It should be used in stereo, at least as fas as the L and R outputs on the device should be connected to L and R outputs of your soundcard or sound device.

Then use BiaB to invoke a Mono output from there, which will mix the L and R into Mono properly.

Some certain patches in the SD2 may be using one channel for the Dry and the other for the Wet, although I haven't noticed that. But it could explain your situation. I think your problem lies in a setting in software plus the fact that you are trying to use a single mono cable where a stereo hookup to computer is needed. If you want mono then, let BiaB sort that out. This is particularly important for those patches in the Ketron that are Stereo. For example, using only one channel of the Grand Piano would mean that you are missing critical audio data for one half or the other of the keyboard.

Nothing about MIDI is intuitive. But if you work with it a little at a time, do some google searches to find out more, keep working with MIDI, eventually things do indeed start to become second-nature if not exactly intuitive. The Ketron is a State Machine. it only does what it is told to do at any given time. Not knowing what you may have inadvertently told it can be a problem.
