well i'm running Sample and Keys, both set to 16 steps, with the Sample
playing 4/4 kick, and the Keys, just one note. what a mess. not hitting at
the same spot on each pass at all.

:- (

and let's talk about the fact that they don't start together either.
how are you supposed to do anything with that?

am i missing something?

it's doing 10steps to more or less pulse with the 4/4 on 1/1 setting.
this isn't right... wdfff... ??

these shoula definitely had some sort of dinsync. oh, and now it's lost it
completely... it's on the off-beat, ... drifting... not synced at all.
:- (

oh it's sort of syncing on 1/2. waiting for it to drift.
think i have the tempo set to max range though on the Keys though.
could be that.

still bloody annoying they don't start together.
i noticed a 'reset' label on the pcb. could anything be done with that?
looks like only destined to be used as slaved MIDI modules.

well the reason for the non-sync was quite weird:
i was using a mono 1/8" to 1/4" cable for the audio out, into a mono input.
it's a stereo output anyway.

when i swapped for a stereo cable, problem went away.
so it was some sort of short, messing up the sync.

That's really weird that your audio cable should affect the sync. Have you any idea as to why it does?
I tend to use a TRS to TS cable for my Volca outputs to save on channels but have only ever noticed that affecting the quality of the Beats' output. I run the Volcas using MIDI from a BSP and don't even use the sequencer on the Beats preferring to trigger it's sounds via MIDI instead.
I've never synced my Volcas to each other and have only used the sync-out to run my Pocket Operators, for which they work brilliantly and perfectly on time, just need to remember to re-arm the PO's if I want them to start on the first step of their sequences.

I'd hazard a guess that the "reset" point on the pcb could be for adding a way to pull the sequence back to ready position similar to how DINsync works with a pulse sent to activate, but in the Korg 2 pulse per step format.

pretty sure it was because i used a mono cable out of a stereo output, into
a mono input - swapping cables was what fixed it anyway.

the Volca Sample has a Pan parameter, and an extra 8th Global setting for
Sync, letting it run at half speed (once a step, once every 2 steps)

note also that the sync socket is mono, whilst the cable is stereo.
does this suggest a short-to-ground creates the sync pulse? so
if ground is affected by using a mono cable on a stereo audio out,
a short to ground might happen there too.

i'll see if i can reproduce it. the Beats should be ok(i think...), it's a 2x mono output.

It is a well known issue, the common ground between the sync and audio sockets is why, with a mono plug you are effectively shorting the ring and tip together, meaning that the audio signal on the ring is going to ground causing it to put noise on the ground which will mess up the sync.

The solution if wanting to use a mono audio cable is to ensure that the ring is isolated from ground, you can make a cable or use adapters to achive this.
