Hi,
If the playmode in the Keyboard settings is'nt set to "Legato", then the Sequencer reset to step 1 at every new played note and the clock restart.
This is'nt the case for the Arpeggiator.
So some options you have is:
1. You have to not play legato style to restart the clock, when you use the Arpeggiator.
2. Use the Sequencer instead of the Arp.
3. Play the sequences/ Arps manually note by note.
4. The drummer learn to play to a click track (a metronome).
I guess a restart sequencer parameter could be applied for the Arp (i would like that option), but perhaps you also would like a certain note order to be applied the played notes, and then perhaps it can get triggy, as this also have to do with the selected Arp mode.
An Arp that suddenly have a jump in the beat is'nt good or pleasant for a listener. Then better to play the arp note by note, so the drums and arpeggio is being adapted without sudden change.
Do you know of an Arpeggiator that can do what you wan't?
