Problem is that the first note/attack is not in time with the rhythm. It has some unreliable glitch and therefore it is impossible to get a tight rhythm. I have tested this by trying to play along with a metronome or drum machine.

Ok, we tried to reproduce this problem… With the Harpeggiator the intention was that you would use the performance switch to retrigger the sequence. Since the H9 doesn't have an onboard performance switch, you need to hook up an aux switch or MIDI footswitch to trigger the performance switch instead.  We set this up and tested it against the latest release, and everything was working as expected.  Maybe, you guys were expecting this to work in some other way?
