Subject: Re: [PolySix] Arpeggiator Timing - Slight Irregularities?

From: Bob Grieb <bobgrieb@yahoo.com>

The arpeggiator is code inside the key assigner.   An interrupt
signal is generated by an edge either on the remote trigger or the
oscillator on the front panel board.   When this interrupt comes in,
if the arpeggiator is enabled, the key assigner advances to the next note.
So I think the delay when changing direction is probably in the code,
and would be the same for internal or external trigger.

Subject: [PolySix] Arpeggiator Timing - Slight Irregularities?

 
Anyone ever experience any slight timing issues with the polysix arpeggiator? Usually for me it only occurs when i have the arp in full range setting of 2 octaves UP/DOWN.. There is a slight hiccup after going UP, just before it begins to come DOWN. It seems like the down begins a dozen or so milliseconds late while it processes the upcoming information. The funny thing is this even happens with the ARP being triggered externally via the TRIG jack. 
Is this a result of digital lag time in the microprocessor? Or is this actually something i can adjust or repair?
