Thank you Vos for the reply
I found the solution by record the arp settings (per track) under patterns.
the songs has different arp settings under different kits and tracks, and the play back was triggered by ableton live so it was a pain to switch the arp setting live for different kits and tracks during live performance.
i didnt quite get it at first because all the midi note was sequenced by ableton live (I had 4 channels setup in ableton live and they are sync to the 4 tracks on the A4, didnt know that I could just record the arp setting without keying the notes … so yeah its all good for now ^^ just that I have to switch to match the different pattern and kits.
