Acetate drum sample not working?

Lately I’ve noticed that one of my favorite drum samples, Acetate does not work as expected. No sound at all. I’ve tried resetting the Op-1 and at times it will work then all of a sudden go quiet again. Anyone with any idea why this might be so? It is normally on button 6.

Is your OP-1 at an angle? Acetate has an LFO with Nitro tied to the accelerometer.

Thanks for that. It sounds pretty close to a solution. I thought something was tied to it but couldn’t figure it out.
