Clock IN from Volca Sync

[Jesse Johannesen]

I've been trying to get the NDLR to accept external clock from a volca drum using the Sync Out to the NDLR Clock IN. 
I've set the NDLR Clock In to "ClkIn CV" yet the NDLR isn't affected by the volca's Tempo. Is it that the Sync rate isn't really CV but rather a simple square pulse?
My big question: is there a way to get Clock In from a volca?

Hello,

Try using mono jack cable (TS) for NDLR, the ones that came with Volcas don't work for sync in/out.

Good thinking, I do believe it is a mono jack on the NDLR, so that could be the issue, however I have to ask @gopilot when you say the Volca doesn't affect the NDLR's tempo that suggests that the NDLR does in fact exhibit a tempo to begin with? If so the settings aren't correct. If it is set to external clock, the NDLR will not operate at all without a clock signal at the input. Can you clarify that before we proceed with further troubleshooting.
Thanks,
Jesse
