For those of you looking to sync your DMG with any device from the KORG Volca lineup, here is my most recent video where I sync three Volcas and a DMG:

I have also uploaded a couple videos that have the PO-20 Arcade in them, but they are not synced, which is why at least one of them sounds a little off at some points. While the Analog Sync does not have a start pulse(and the majority of them don't anyway), it is excellent for synchronizing devices. I have found that all of the KORG Sequencers are perfect for this because they can be daisy-chained to hold the entire setup. I am free to answer any questions on my setup! Enjoy!
