Rob, that is not a bug, and not the same issues I'm having
. When you assign all 6 voices, there's no voices left so any pad not assigned to a voice won't do a thing. This is why I start topics before reporting a bug in this topic, because I want to verify if it's user error or if more people are experiencing the same.
I'm having trouble with playing a beat and designing sounds, some voices just start randomly dropping out. Sometimes for the duration of one loop. But sometimes the whole voice is gone until I reboot. This happens to multiple voices sometimes too and not the same ones either, so it's not related to specific voices.
I'm still not sure why it happens. I'm going to try cleaning the flash of Tempest and reloading my beats and sounds to see if it helps tomorrow.
