I could not find anything regarding this apart from tons of posts about the Octatrack’s overall “sound quality” or sound quality comparisons. This is about something else, because when monitored through Thru machine etc. the OT sounds just fine.
This relates specifically to results from sampling Digitakt (stereo out / stereo in A B on the Octa) into the Octatrack. A sound file saves a thousand words, so here is the example: the first 4 bars are Thru machine monitoring (sounds fine), the last 4 bars are the sampled version of the same on the Octatrack.
Clearly the quality drops and/or there are some phase issues.
I’ve eliminated the cables being an issue because the Thru / direct monitoring sounds fine (as can be heard in the first 4 bars of the example file).
Also eliminated the Octatrack being the problem (maybe?), because sampling the Analog Four (inputs C D on the Octa) sound exactly as monitored.
What is going on here?
