MIDI keyboard along with accompaniment qsynth

Question

I recently got the MIDI keyboard connected on my ubuntu 19.04 using qsynth referring to this.
I can now hear the keys when I play. But, I can't still hear the auto-accompaniments (Rhythms and in-built Chords). I use a CASIO 7300IN.

Answer 1

This is NOT a qsynth or audio driver setting. All the channels were correctly configured. This is a configurable MIDI setting on the keyboard to allow/disallow auto-accompaniment. On my keyboard, it was disabled by default.
