RA-90 and 01WProX - how to connect?

[PolishPrince]

I haven't used my RA-90 Real Time Arranger for a long time. Years ago, I used it connected with my 01WProX keyboard and was able to play melodies with the RA-90 accompaniment. And it was great!
I am trying to create the same setup – but cannot remember how…

I have MIDI-IN and MIDI-OUT connected to MIDI-OUT and MIDI-IN respectively, and L/R audio cables between keyboard and RA-90 (this is probably wrong).
I remember connecting this setup to my amplifier, and was able to hear both instruments!
Now I cannot get to that…
I may have some wrong buttons set on the Arranger, or wrongly connected the L/R audio - but cannot figure it out.

Can someone, please, help me with the setup?
Many thanks in advance!

I found the way to do it:

To connect Roland RA-90 (or RA-50) Real Time Arranger and synth piano with the two audio input amplifier:

Turn ON:
FIRST: Piano
SECOND: Arranger
(While turning on RA-90, you can hold “1 PIANO” or “2 PIANO” button to set the dividing point on the keyboard to be "B2" or "B3" respectively.)


CONNECTIONS:
MIDI-IN, MIDI-OUT to MIDI-OUT, MIDI-IN
Arranger OUTPUT L(MONO) to amplifier INPUT-1 (or 2)
Piano OUTPUT L to amplifier INPUT-2 (or 1)

I wonder if someone had the same problem connecting, or was it me only.
Let me know!
