I currently have a DDJ-400, which I'm happy with, but I want to upgrade to either DDJ-800 or DDJ-1000 because I enjoy scratching on a controller and the jog wheel screen with the rotation indicator really makes a difference there.
I went to the local DJ shop bringing my own PC (Dell XPS 15 running Windows 10) and tried out the DDJ-800 and DDJ-1000 and found that these units produce a weird wobbly kind-of sound when scratching at medium-to-low speeds. There is no problem when the track is just running or if changing the tempo slider. It's also independent of Master Tempo enabled/disabled. The same problem does not persist for the DDJ-400 (also tested this at the shop). Changing audio device settings in Rekordbox Preferences to various settings does not seem to help. All controllers use 44.1 kHz sampling rate. The DDJ-800 and DDJ-1000 use ASIO driver, but DDJ-400 uses WASAPI driver - could this be the cause of the issue? I don't own a Mac computer, and the shop didn't have any computer I could test on. One other thing is, that I cannot change buffer size for the DDJ-800 / DDJ-1000 as the the slider is simply grey'ed out. I can however change buffer size for DDJ-400. Are my drivers incorrectly installed or what is going on?
I used Rekordbox 6 (and by the way, Rekordbox 5 does not reproduce any different results) to record the three cases which are linked here. Also find screenshot of audio settings from 'Preferences' in Rekordbox.
I'd really like to upgrade to DDJ-800 / DDJ-1000, but if the sound is like this every time I'm scratching, I probably won't anytime soon. Can't find any other info anywhere related to this issue --- but I can't be the only one experiencing this?
