hi
dont know if you remember but i was speaking to you a while a go about a mac glitching when using traktor.
well i just got my MBP thru a couple hours a go and was just wondering if you could share any tips on what to turn off etc to ensure smooth running?
many thanks!
Hey, I don’t have a Mac, I have a PC. But you shouldn’t have to do too much to get it stable.
It is best to turn off WiFi and Bluetooth, especially if you are performing or recording but you should be ok other than that on a new Mac.
It is a good idea to stress test Traktor at your sample rate and buffer settings. I have the Audio 8 and I set it to 96000, I found this made a big difference in sound quality over the 44100.
I then tested it on a low buffer setting with two tracks playing, all the effects on and the key lock on and play with the effects. If there are any glitches I stop everything, change the buffer size, restart Traktor and try again.
I found that it would cause glitches at 128, and was ok at 192. I ended up going for 256 as at 96k this has a very short latency and is perfectly stable.
thats great mate thanks for your help, will have a go now!
had a little look, does sound a lot better at 96k, can get the latency down to .5ms, but i cant seem to find this buffer you are on about, think im being blind?!

What audio interface do you have?
Usually there are two things you can change on the audio interface settings. The sample rate, ie 44.1KHz - 96kHz, and the buffer size, 64 samples - 512 samples, or more.
Because the buffer size is in samples for any given buffer size the higher the sample rate, the lower the latency. But the higher the sample rate the higher the CPU load on your computer.
The buffer is used to prevent clicks, pops and other artefacts whilst playing music. So the higher the buffer the less likely it is to have clicks, but the higher the buffer the bigger the latency.
So the trick is to get the
buffer high enough that there is absolutely no chance of clicks but low enough that you do not notice the latency when playing. To achieve this I think you will need to raise the buffer amount if you can, use the stress test as described above then up it one more for luck if you can.
i have the audio 8, in the traktor audio settings all i have is latency and sample rate? or am i in the wrong place here?
or is the latency and buffer the same thing?
Buffer size divided by sample rate = latency
eg:
256 samples / 96000 Hz = 0.0026 seconds or 2.6 ms
128 samples / 44100 Hz = 0.0029 seconds or 2.9 ms
It might be different on the mac, if you can’t edit buffer size but you can edit latency I would go for 2.5ms latency and see how you get on.
cool nice one mate will check it out!!
