Thanks, Rikki.
Many discussions were had about the 7k book but I was of the opinion that so many 6/65k books having been sold all over the world, having paid once, owners would be reluctant to pay again for an updated book covering similar ground to the old book. In any event an official book was requested for the new features and there was so much new in the 7k with sd and audio and pc functions etc that it was easily enough to justify another book for those.

I did outline the chord modify change in the old book but a detailed use requires a good knowledge of harmony theory so a full explanation was really outside the remit of the 6/65k book.

Basically you can program how any style or any pad responds to chord changes, and it is a very sophisticated tool which gives superior results to the other systems used by some other manufacturers, but is overlooked in virtually all discussions that I ever see, truly one of the great unappreciated features of Technics boards.

You can not only program a different pattern for major, minor or 7th chords for instance, or hold a note in the accompaniment after you change chord in the left hand, but keep accompaniments straying too far from their inversions while changing chords etc.

This is not only programmable for each individual accompaniment track, it is programmable for each individual note of any track in composer or pad in step record. Thus different patterns will result depending on which chord you play in the left hand.

For example if you record C, G, E in a pattern and play C7 in the left hand and trigger the pattern with the default global “7th G>Bb” setting you will hear C, Bb, E. Now the seventh has many uses and you may not want to signal a direct resolve to the perfect cadence or many other reasons.
Change the global chord modify change to “7th C>Bb” and when you play the same pattern in C7 you will hear Bb, G, E – the point being that this has been done without changing any notes in the pattern programming at all.

Not only that but each note can be set individually, so a series of Gs and Cs can be changed differently, or not, or even left alone as the harmony changes - programmable individually for each individual G and individual C in the pattern. You have 23 types of response to different chord changes to play with for every note of accompaniment harmony in every track of preset, composer, custom and pad.

The problem of clashing added notes as the harmony changes are either ignored in other manufacturers systems or added notes are simply not used in the styles to their loss. Technics met the problem head on with chord modify change.

best wishes to you too
