Not sure if anyone noticed this yet, or even mentioned it already.
I think most of us thought 16 bit only, but:
From the manual download:
AUDIO FILE COMPATIBILITY
The Octatrack can handle different variants of audio files depending on the type of machine used.
Static machines can handle 16 bit/44.1 kHz wav and aiff files, either in mono or stereo.
Flex machines can handle 16 or 24 bit/44.1 kHz wav and aiff files, either in mono or stereoOS 0.99E
So I tried using 24 bit/44.1 kHz samples in Flex machines, but most of the time I do get errror in the sample slot.
Sometimes it worked and sometimes only after rebooting the OT, but then I also get a neverending scrolling bar on the display often, because the OT seems to have problems loading 24bit samples.
I couldn´t even load a different project as well often, because > a neverending scrolling bar wouldn´t let me.
So I did "thru" on each track then to finally be able to load a different 16 bit project again.
24 bit doesn´t seem to really work....yet.
I´ll write a bug report to elektron.
