Help! Lost 95% volume with the MD/HT drum voice

Hi everyone,

Out of the blue after playing for about an hour, the MT/HT drum voice dropped substantially in volume. It occurs in the headphone and the dedicated outputs. Re-calibrated the machine after leaving it on for a few hours, tried loading a brand new project to make sure it wasn’t something wrong with the patch. I can’t audition samples with this voice either, there is 0 volume when playing samples. Running 1.21C and reinstalled the software too. Feels like a hardware issue to me!? I’ve sent a support request, wondered if anyone on the forum had heard of anything similar?

Any advice would be appreciated.

Thanks,
Richard
