Hi pueblofunky,

Thanks for get in touch with us. Pioneer DJM900SRT has 4 channel so you can play records or music from CDJ (CD/USB) or iPod connect through one of the line channel while doing changeover. You can unplug USB and plug next persons USB in.

For example, If you are using channel 2 & 3, plug external music source on channel 1 or 4 and play it while doing change over.

I hope this clears things up.

Kind Regards
Rui

Thanks a lot - I understand.

But sometimes 2 dj's are playing together. DJ #1 2-3 tracks, DJ #2 2-3 tracks.

So both can not connect permanently the laptop on the DJM900SRT.

It might not be a problem at the moment because not all resident DJs have Serato DJ (yet) but maybe during the next 2-3 month because the DJM900SRT is fix in the club now.

For future mixers it might be better to have 1-2 USB per channel and select the USB 1 or 2 on the input selector on the channel mixer. I think there is no other way in the future. ;-)

Maybe below or at the side of the input selector - not behind where all other connectors are - because this part is not accessable for us DJs in the club (something built over to avoid connect/disconnect cables by DJs).

Correct my sentence above (sorry): "For future mixers it might be better to have 1-2 USB per channel and select the USB 1 or 2 on the input selector."

Or 2 USB (for each laptop) and the channels can be selected to a USB (1 or 2) - like it is possible with the faders. However - it is more complex and not so nice.

Hi pueblofunky,

Thanks for reply. Yes, 2 USB input will be awesome. You can always leave some ideas on our feature suggestion forum - serato.com

I will close this thread for now however please do not hesitate to start new thread for any help in the future.

Kind Regards
Rui
