i’m still new to recording myself so perhaps i wasn’t setting my ZED-10 up correctly. but i had alot of feedback problems with it and ended up selling it for a proper audio interface.
as a mixer, i don’t think it’s USB drivers are intelligent enough to allow monitoring of ableton’s output without feeding it back into the DAW.
Zed 14 user here… I have had no issues with recording via USB to Ableton or SoundForge… You do know that the USB is only 16bit 44.1 Khz and only supports left/right channels… 95% of the time I record to a Roland R-05 field recorder with no loss in fidelity…
