DJM 900 Nexus with USB connected to imac without CDJs.
I set my Audio settings of my imac to input DJM 900 Nexus and output DJM 900 Nexus. Then I put the Audio settings in rekordbox to Built-in-Output (not DJM 900 Nexus because I cant use the DJM 900 Nexus Fader when I put the audio settings to DJM 900 Nexus in rekordboxDJ!! the trim section and effects are working well but as I metioned the faders of the DJM 900 NXS are not available).The mixer-Modus in rekordbox on intern (Intern Mixer-Modus). Input Record is on master out.
Does rekordbox uses now the soundcard of the DJM 900 Nexus or does it still record through the build-in soundcard of my computer when I have the audio settings of rekordbox to built-in Output? Does rekordbox record from the audio input (Nexus soundcard) or from the built-in Output (Computer soundcard)? Or do I have to change the audio settings from rekordbox to DJM 900 Nexus, that it will record from the soundcard of the DJM 900 Nexus? For me it seems like its still recording from the build-in Output of the computers soundcard instead of the nexus soundcard.
When I put the Audio in rekordbox to DJM 900 Nexus I can not use the intern Mixer of rekordbox. I want use the intern Rekordbox-Mixer with the DJM 900 Nexus soundcard to record.
Second Problem: when I change the audio settings of rekordbox to DJM 900 Nexus (instead of built-in Output) I can not figure out how to record all 4 chanels. In rekordboxDJ it just shows record possbilities of chanel 1 to 4. That means I can just record 1 of 4 chanels. It looks like a have to connect all 4 chanels to 1 chanel to record. It looks like its not possible to record in rekorboxDJ with the soundcard of DJM 900 Nexus without CDJs.
