I could imagine that this is an delay caused by an high of the A-190s
MIDI buffer by an large amount of MIDI messages. I don't have a A190 but
I know similar behaviour from other MIDI-CV interfaces (e.g. the
MS-101), or from old MIDI-synths. Usually these delays it do not stand
out, but the regular rythmic structure of arpeggios makes them "visible".

You should check that no other ableton track/element sends to this
MIDI-Port - also for other MIDI-Channels.
