Jomox Air Base 99 individual output issues

Hi,

not really sure where to put this but thought here might find someone who can help.

I’ve been using the individual output of my Air Base 99 (OS 1.15 © ) and have run into some issues.

For some reason the hi and low tom sounds have a strange clip in the decay. It doesn’t seem to be dependant on the decay setting though.

Some of the sample based sounds are also making a strange clipping sound after the initial sound has ended.

This doesn’t happen when using the main outputs only when a cable is plugged into the individual outputs.

Cables are mono jack as per the manual.

Has anyone come across this? Is it a design flaw? Any help much appreciated.
