MOTU 24i connected by Firewire via MOTU PCI 424 card.
Recording software :- Steinberg Cubase SX v 126.96.36.1994
The intention was to record a 100-minute live show.
I configured the MOTU 24i interface via PCI Audio Setup to activate 24 inputs. I was concerned about potential distortion and or crosstalk from the expected high levels at the output from the 24 tracks being mixed so I de-activated the outputs. I don’t believe this has any relevance.
In the Project Setup I increased the recording length to 2.30.00.00 (2.5 hours) at the 44.1kHz; 16 bit Record Format and AIFF File Type.
I confirmed that each of tracks 1– 24 had the corresponding input assigned to it. At sound check I could see that I had the correct sound sources registering on all inputs of the MOTU 24i. I was concerned about the strange waveforms seen after the test recording and I and another Cubase user checked the settings and decided the settings were correct.
The recording ran uninterrupted ( with no problems) for the duration of the show. When I checked the recording I had tracks 1-8 duplicated on tracks 9-16 and 17-24.
What went wrong?
