Yamaha Montage and Montage M Forum • Overview of the 67 element Chordz 2 Chill 2 performance

It may come as a bit of a shock when you first notice the 67 elements that the Chordz 2 Chill 2 performance on the new M models use.

Naturally you wonder what they are doing with all of those elements.

The first hint comes when you play a single note and get a beautiful 7 note arpeggio. The attached spreadsheet provides the details nicely formatted into columns. I extracted that data using a custom Java app that processes Bulk Exports and puts the data in a form that I find more useful:

The forum formatting compresses everything but you can spread the data out so each column header has one data item or just see the attached spreadsheet.

37 371 48 59 71 127 0 29

The above shows just one octave - the others are similar

Low Key range is 48 and high key range is 59 - so these elements are handling one entire octave.

There are 2 groups of 8. The first 8 use the same wave number (367) as do the last 8 (371).
The first 8 are velocity 1 to 70 and the last 8 cover 71 to 127.
You can see that only the first 8 has KeyOn Delays and they are all different. That is what produces the
'arpeggiatted' part of the sound.
The last column show the first 8 having different coarse tune values. That is what creates the chord pattern.

So it takes a good ear to hear it but that group of elements, for that octave, is producing an 8 note arpeggiated chord.

The last group of 8 doesn't have any KeyOn delay but has the SAME set of coarse tune values.

Those 67 elements have a simple organization that is EASY to understand when you can look at the data together instead of one element at a time.

Hopefully the upcoming ESP (Expanded Synth PlugIn) will provided similar funcitonality.
