hello everybody. i´m although to learn the new features of my mpc with JJOS128XL and now i be engaged with Audio Tracks but i dont understand what advantage it has compared to normal sampling from the record menu. how and for what do you use Audio Tracks???

Glad you asked. Audio tracks are a bit underdeveloped but really awesome and I encourage you to use them.

Here are a couple of scenarios I use them in:

* to record an external (eg. midi synced) instrument directly to track so that it'll play back exactly like you need it to in your sequence.

* If you know how many bars you want to record you can set a loop in mpc before recording and just hit [REC]+[PLAY] to start recording from the current position and end at "loop-end".

* bring a backing-track directly to the sequencer without needing to create a program etc.

You can further tweak these sounds by setting FADES and Q-link TUNE and or FILTERS. Quick 'n easy way to get useful stuff to your sequence. (Applies only to OS2XL/OS-XL)

Also, probably one of the main advantages, audio tracks can start mid-way through the sample.

I.e. you can scroll to any point in the sequence, hit play, and the audio track will start the sample at that point.
As opposed to just assigning a long sample to a pad, which would only trigger when you hit Play Start.

You can also mute/unmute on the fly with an audio track (there's a setting to enable this), so in the track mute window, it'll always key in to the right point in the sample whenever you unmute the track.



Also, I think that audio tracks sorta have polyphony "priority": if you have an audio track, and, say, you have a cymbal set to POLY mode spamming really fast, the audio track won't get cut off from the cymbal stealing its polyphony slots. With just samples assigned to pads, it's easy to hit the 32 limit (or lower, I think jjos is buggy with its polyphony management, so it won't actually go up to 32 sometimes)

Hmmmm ok, i must be more engage with audio tracks but i still think that there is not much difference to the normal sampling. but it can be useful when i want to record a pattern from LSDJ or Nanoloop direct to save some worktime:-) Thanx for the quick answers!
