in the manual it says it has alternate looping and forward looping, but doesnt mention crossfade looping, this is the only loop mode i really use, and have heard it has it, although the manual leads me to believe otherwise.

could someone confirm for me that the 4k does in fact have crossfade looping please?

im talking jjos2xl style crossfade looping.

thanks

could someone please check this out for me on their 4k? i am about ready to pull the trigger and get one, but i really wana know about this feature before i do.

thanks :)

this is the exact feature im looking for, its at about 6:03 of this video.
notice how he just taps the pad and it plays the loop over and over, without having to hold the pad down?
also notice how the loop sounds smooth cause of the crossfade? its not alternating forward to backward and its not looping just forward is it?
can you get an effect like this on the mpc 4k?

jjos 2xl can do it i know for sure, it just uses the crossfade feature. it differs from how its set up in the 4k as far as i can see though.

in jjos, you just select forward, alternating or x-fade, but in the 4k as far as i can tell is you can only select forward or alternating, but there is also an option to put a crossfade in either one of these, so is the 4k actually more flexible than jjos?

i cant tell what the x-fade loop is doing exactly (regaurding direction) in jjos, but i know thats how i like it to sound, so if i add a crossfade manually on the 4k can i get this sound out of it?

side note: is the crossfade only destructive in the 4k? i would like it to be non destructive.

heres the video check out about 6 minutes in.

i really need to know this before tomorrow cause the auction ends in about 15 hours, i would really appreciate it if someone could check tonight.

thanks

To be exact: from pp172.....
Applying crossfading
Crossfade looping is a function that rewrites the waveform before and after the loop
start/end points so that the loop will be connected smoothly. This is a convenient way to
minimize the noise that can occur where the loop is joined.
1. In the Trim/Loop page, enable looping and set the loop start/loop end points to
the approximate locations you want.
2. Move the cursor to the LP start or LP END field, and press the [WINDOW] key.
The Find Loop popup window will appear.
3. Move the cursor to the X-fade length field, and specify the length of the crossfade.
The setting of this field specifies the length over which the waveform will be rewritten
before and after the loop point. If this is too short or too long, the loop will not sound
natural.
4. Move the cursor to the Curve field, and select one of the following as the
crossfade curve.
• LINEAR ......................Apply linear crossfading before and after the loop point.
• LOG .............................Apply logarithmic crossfading before and after the loop point.
• SINE ............................Apply sine curve crossfading before and after the loop point.
5. To execute crossfade looping, press the [F4] key (X-FADE

i read this in the manual, but does that mean that the crossfade loop is only destructive? do they have a ndc version of crossfading like on jjos2xl?

if it is destructive, would i still have to apply the release time?

thanks alot for your replies guys!
