Is there an easy way to switch off or control the touch sensitivity of the keys? Say I am playing an organ and I do not want the volume to change with the speed the keys are hit. I am also sometimes having problems with some of the strings where I must hit the keys a little toso hard and all of a sudden one chord is much louder than I want it to be. Can this be assigned to your assignable knobs?

Hi Mike!
Welcome to YamahaSynth! Thanks for the questions.

Yes, you can both globally make that adjustment and you can make that adjustment on a per individual Voice basis. What you are referring to is called “Velocity” in the electronic Synthesizer. In general, it is the speed of the key press that makes it “touch sensitive”; that is, the faster a key is depressed, the louder the output level, when Velocity is applied to ‘amplitude’.

Setting the VELOCITY CURVE globally:
Press [UTILITY ]
Press [F1] GENERAL
Press [SF3] KBD
Set “VelCurve” = fixed
Set the Velocity value 1-127 (127 being maximum velocity)

Affects all programs... that’s the good and bad news. Good, because it’s quick and easy. Not so good, because it affects all programs!

We mentioned, that this Velocity Sensitivity is available within each and every Voice. For example, all of the organs in your MOXF are non-Velocity Sensitive. They all play at a fixed volume level, by design. Try them again, you’ll see what I mean.

They were programmed that way because that is fundamental to the “behavior” of an organ. The organ, as an instrument predates the piano by approximately 2000 years... the piano was the first “touch sensitive” keyboard circa 1700AD... (was very controversial in its day... the harpsichord ruled at the time, and the harpsichord is non-touch sensitive as well).

This velocity sensitivity within a Voice can be found by Editing the individual Voice Element itself.
Call up the String Voice “Ens Mix” (this is a one Element Stereo Waveform that is the entire string orchestra)
Press [EDIT]
Press the track [1] button to enter Element edit
Press [F4] AMP
This is the Amplitude, it controls how loud this Element will be
Press [SF1] LVL/PAN - this is the Level this Element will sound
Press [SF2] VEL SENS - the “LEVEL” setting here is how it responds to Velocity
Currently it’s set to LEVEL = +17
Change it to 0 to remove Velocity Sensitivity.

At a value of +32 you have the linear curve; for each increase in effort there is a increase in output
At a value of +63 you have a curve where only maximum velocity produces a result. This is great for crossfades - where other Elements sound at lesser velocities, and the +63 takes over only at maximum effort.

+0 is the setting you find on all organs, harpsichords, many AnalogSynth sounds... because they do Not respond to velocity

All negative values work opposite the positive settings

The advantages here are many... notice how you can customize the response further using the “Curve” and “Offset”.
The reason I had you do this with a single Element VOICE, was so you would be able to hear your changes right away... you have this same degree of control over each Element that makes up a Voice (8 max).

You can then STORE your edited version to the User Bank.
