Hi Phill!
I want to take advantage of your kindness and knowledge again and learn more about MOTIF XF and also sound engineering and preparing samples.

I found this article while I was reading about how to adjust my own samples and came up with the term "Phase Locking" in this article:
Title

I didn't know I can apply this to samples. Now will you please explain:
1- Are the waveforms of the same instrument in MOTIF XF are phased locked as described in the above articles?
2- Is it possible to create a seamless, smooth transition between soft/medium/hard samples of lets say a brass instrument?

For the 2nd question, what I understood from the OP is that when I play the first note softly, by increasing the modulation controller's value, the loop part of the medium and then with higher values the loop part of the hard samples are crossfaded with the loop part of the soft sample (depending on the modulation controller's value). Is such a thing possible on MOTIF XF?

Thank you 🙂

*** I didn't understand the article completely. Can someone please also explain how phase locking (aligning) can improve for example legato? And is this technique useful while creating samples for MOTIF?

Yamaha is very tight lipped about the process they use to reproduce the samples you hear in the synth. AWM2 is a proprietary method of storing and retrieving sampled audio for use in synthesis. Since in the Wave ROM you will find data (especially among synth waves) clearly marked with the phase, you can bet that it is definitely a very important part of what is going on. Also data can be mixed and matched... for example, waves with a - or + sign indicating the direction the audio is being stretched... this can add more interesting harmonic movement in the resulting sound. Not all three strings on the mid-upper range of an acoustic piano are locked. Perfect is not always applicable in musical tones... perfect is not perfect in music. 🙂

When we get to interview some of the programmers they maybe able to shed some light on this subject. Usually, the technology behind the creation of the data is cutting edge, and if explained wouldn't really mean much to anyone but those trying to reverse design a product... so they just come up with a phrase like, proprietary method of storing and retrieving sampled audio...

Some of what they do would scare most mere mortal musicians anyway.

I know I work for the company, but just listen and compare Yamaha with any other synth, judge for yourself. And not trying to be discouraging but it is not likely you will be able to amass the tools the that Yamaha uses to create and manipulate sample data. Yamaha's facilities are awesome!

Thanks for your response Phil. Informative as it is always.

Sometimes it may sound like that I'm asking a silly questions but I'm really and honestly interested in knowing it and I go and read about it as much as I can and understand. I have no intention to undervalue the effort Yamaha puts in producing its products whatsoever.

I like my MOTIF XF and I love to learn and create sounds professionally. This instrument is very capable and I'm not using it up to its maximum capacity. I also want to know how to efficiently fit it in my workflow (although I'm not a pro and just a hobbyist).

Your thoughts are always helpful even if you blame me for asking a silly question. Any answer will help me to reorient towards the correct path.

BTW, I found this post:
PHYSICAL CONTROLLERS AND DESTINATION PARAMETERS

Is it possible to do the fade effect for more than 2 element? for example 3 or 4?

Sure, the Motif XF has six Source/Destination Control Sets. Plus it has other methods of moving between the active Elements ... for example, I've setup seamlessly transitions between entire complete sets of Elements using the XA CONTROL. This allows you to move from one complete instrument to another without any cutoff in sound.

Please see this article with a downloadable example:
Motif XF Advanced Application: Seamless Transitions

If you have any questions post back here.
