Check the manual for how to have the Sequencer play either the Song Parts or the Keyboard Parts (per track). I think the issue may be somewhere in there. I have done full arranger ‘captures’ to the Recorder, and they played back correctly iirc…
I probably saved the Performance, and recalled it before playing back the Recorder, which likely takes care of the volumes etc..
Do you have ALL the manuals? There were at least two, possibly three, and maybe some addenda for new features of bugfixes added later. Plus I found a bunch of sysex info not in the BK9’s manuals in the MIDI section of the BK7m’s manuals.
Just go over the 16-track sequencer’s section about track ‘type’ (or something like that), and make sure in the MIDI section you’re not filtering anything from the Keyboard Parts.
Bottom line, it’s not hard to go to each track edit page and type in the volume and effect edits. But if the MFX isn’t coming up correctly, I think you are playing the track into a Song Part, and not the Keyboard Part…
If that turns out to be the case, you will have to assign MFX and EQ manually to copy the Keyboard Parts’ settings. Iirc, there’s no way to copy a setting directly. Mind you, if you didn’t edit the MFX, just call up the type for that track (in the Makeup Tools) and save.
