Curve

At zero, this is flat i.e. the level (as well as some other values we will come

to shortly) is always the same, no matter how hard you play the keyboard.

The small graph indicates keyboard velocity in the X-axis, and how this is

translated into levels in the Y-axis. For instance Curve 1 means that keyboard

velocity is translated linearly, whereas Curve 3 means that it will take a lot

more energy to reach medium levels. Try playing the keyboard very

dynamically using each of these curves in turn - you will soon get a feeling

for each one, and understand intuitively what each individual graph depicts.

Sens

Sensitivity. This parameter governs the degree to which keyboard velocity will

affect Level. The default value is +32, but with Velocity Curve at 1, values

around +27 are better (for my personal playing style at least). Note that setting

negative values here will make the sound softer the harder you play. Set Sens

to +0 so you can hear the effects of the following parameters in isolation:

A-Sens Attack Sensitivity. The Attack time is affected by how hard you play the

keyboard. Try setting A-Sens to +63 and the nominal Attack (using the

A slider) to 40, then alternate between playing very softly and very hard.

When you are finished, take both A-Sens and Attack back to zero.

D-Sens

Decay Sensitivity. The Decay time can also be affected by keyboard velocity.

To make Decay longer when you play harder, you will have to set negative

values here. Set D-Sens to -50, Decay to 50 and Sustain to zero. Alternate

between playing very softly and very hard, then set D-Sens back to zero.

R-Sense

Release Sensitivity. Similar to A-Sens and D-Sens, but affects Release time.

Env Time KF

Envelope Time Keyboard Follow. Envelope times follow the MIDI note.

Setting positive values here shortens Attack, Decay and Release (all at

the same time) when you play higher notes, and lengthens them when

you play lower notes. You will hear this effect when playing a piano.

TVA stands for Time Variant Amplifier, and this is the section which governs the

overall volume of each note while it is being played - including master volume (Level),

the envelope itself, keyboard velocity, panning and tremolo (via the dedicated LFO).

Having been introduced to envelopes earlier in this tutorial, you should already know

how to set up the most important parameters, but I will go into more detail here.

If TVA is deactivated, this is practically the same as setting maximum level, minimum

Attack and Decay, maximum Sustain and Release of 15. Release is not zero here

because cutting the sound off too suddenly would cause a click. Start with 512:INIT

PATCH and try out the following:

The TVA Section

Level KF Level KeyFollow. Level follows the MIDI note - try setting -200 and play

all the ‘C’ notes on the keyboard starting from the lowest one. Then set

Level KF to +200 and play each of these notes again. You should now

know what “KeyFollow” means! Set Level KF back to +0 and press the

cursor-right button to highlight the next parameter...

Lvl LFO Dp Level LFO Depth. Amplitude modulation from the TVA’s own dedicated

LFO. Useful as a tremolo effect - try different values. Set Lvl LFO Dp

back to +0 and press the cursor-right button again...

Pan Panorama. This moves the sound to the left or right. Try extreme values,

then take it back to zero.

Pan KF Panorama KeyFollow. In a similar way to Level KF, the panorama position

will follow the notes on the keyboard. Note that panning is polyphonic,

i.e. if you play the lowest and highest notes on the keyboard at the same

time, they will be split in the stereo field. Try it!

Pan LFO Dp Panorama LFO Depth. Try extreme values for a deep stereo tremolo effect.
