Re: [linux-audio-user] Re: Best soundcard for DJing with Linux (Poll)

Any "openjay" should really be given this advice to start with. Buy a mixer. Any application that suggests it is a good idea to use the built in (i.e computer) mixer/eq/effects etc is well, in my opinion deluded at best. It's like suggesting to use the computer keyboard for playing a piano synth. Then what you look for on a card are 2 stereo outs to go to your mixer. I REALLY suggest some of the developers of the limited number of dj apps for linux really need to learn how to dj first, on standard equipment. By this i mean a mixer and sl1200's (or copy of if can't borrow/limited for cash) or if that's not possible, a worse option, a mixer and standard club cdj's. Dj apps really should be modeled on turntables or cdj's. Something proved to be useful. Anything you can't do on a turntable is pretty much pointless for djing. A pitch range of > 8% is not in any way a good idea. If i get outside of +-5% it would be a freak occurrence. I've actually used djplay http://djplay.sourceforge.net/ in a small gig. I had my mixer, 2 sl1200's but a very limited collection of vinyl as i was travelling internationally. I used djplay as a substitute for a cdj. It wasn't too bad for that, and much more suitable than the other apps i've used, but in no way to the standard of a cheap turntable/cdj. All linux dj apps seem to have problem with cueing well. By this i mean finding the first cue point, were to release from in normal vinyl speak. On a cdj or vinyl these are scrub over the beat you want and release the vinyl or press cue on a cdj, in time with the beat on the other deck. Try doing this on any linux dj app. Accuracy for pitch is also very limited. For correcting in the mix (after i had the tunes beatmatched and live, i.e both together) i would have to correct the vinyl copy not the djplay copy, as small pitch changes, i.e 0.1% smoothly is VERY hard with current linux dj apps. In regard to cdj/turntable focus, effects are useless. If people want to use effects, they can either route the output of the dj prog through om or jack-rack, or effects loop on there mixer through om or jack-rack. However neither of these are a good idea, as effects are really not a good idea in djing, unless you are really to the level where you can mix perfectly while playing with the effects. After 5 or 6 years of djing (vinyl) for minimum one hour per day, i am not to this stage. Layering accapellas, etc is much more fun. I'm happy to help with any djing questions, however i'm really wondering why none of this style of info is at openjay.org. If you want to put my suggestions there, feel free. end rant! Loki
