ok, so im looking to move my dj setup to the digital(dark) side, been having a lot of trouble trying to get my gear the way i want it. my first priority is ultra low latency, so when i touch the vinyl on the deck the sound coming out of my speakers is as close to using real vinyl decks as possible (latency wise). i purchased a pair of decks (dennon dns 3700) each had their own sound card built inside which controls internal midi in/out for the spinning plater ,buttons and lights ect, and the sound output of the decks via spdif/digital or Stereo analogue RCA. i use the spdif as i believe it will provide lower latency because it doesn't require DAC conversion and provide a better sound(tell me if i'm wrong). i want the DAC done in my genelec speakers at home and either by my mixer (Pioneer DJM800) or the DAC of the sound system when im at a gig.
the idea using these decks was to limit latency by having everything done in the decks rather then having a time code disk or vinyl and an external usb sound card which would lead to more conversion latency. IE: timecode disk to ADC to usb to computer/software to usb to DAC to mixer and maybe ADC of the digital/spdif out of my mixer.
ok now that all sounds great but i have been having several problems. my software of choice is Traktor, but Traktor doesn't natively support the dns 3700 and even though i can bodgy up a midi map the spinning platter still doesn't work properly AND on top of that even if i use different software (virtualdj) i cant get 2 decks to simultaneously work properly and cosistantly under windows.
so i have changed my plan.
1- change from pc to mac pro : macs allow you to use two decks/sound devices simultaneously
2- change sofware to virtualdj: so i can use the spinning platters (but i do love traktor)
and if im still not happy with the spinning platter situation under virtual dj
3- go back to Traktor and use timcode disks with 1/2 internal PciE sound card/s with 2 digital/Spdif ins and 2 digital/spdif outs : this will lower the latency by eliminating the usb connection latency, improve sound and lower latency by using only digital audio. IE: Timcode disk to digital audio to computer/software to digital audio to mixer/speakers
My questions are
1- is there any incorrect assumptions in my statement
2- any help getting any of my earlier or latter setup ideas working properly
3- what sound card/s should i use with the mac given that im using standard rca connectors for digital audio transmission
i have done hours and hours of research on all of this but the research required is getting broader and deeper also i forked out a lot of cash for gear that doesnt work the way i want by being misled by manufacturers or misunderstanding manufacturer info so i want to know all i can before i spend any more money. that said i'm going to get a couple apple macs and the DJM 800 has always been a super solid backbone of my gear.
