I’m a new X1800 user and use it along with my MBP and Virtual DJ. I have all my channels set to USB and mix with a combination of mp3 and ALAC tracks that are all ripped with a Sample Rate of 44.1. I also use VDJ to record the mix internally to a 44.1 WAV file before using Audacity for mastering (and fixing mistakes). Looking in the X1800 utility, I see the default Sample Rate for the X1800 is 48. My question is, should I leave it at 48 or change it to 44.1, in order to match the songs that are being inputted to the mixer? Personally, I’ve always tried to keep audio processing to a minimum when working with digital audio and I’m not sure what the point of upconverting 44.1 to 48 then back to 44.1 when recording internally using VDJ. I understand that there is a benefit to upconverting temporarily in a DAW if you’re gonna be editing or processing but it seems that that would be different from what the Sample Rate setting suggests in the X1800 utility setting. Can somebody set me straight?
