Modulation Wheel Control of the Volume of a Hex Layer Tone

Recommended Posts

Here's a technique that allows continuous control using the modulation wheel of the volume of a Hex Layer tone while you are playing sustained notes (for example).


In a Hex Layer tone set the Rate, Delay and Rise parameters of the Amp LFO to zero. Setting the Rate to zero actually stops the LFO and it then stays at a non-zero value. Choose any of the pulse waveforms (e.g., Puls3:1) for WaveType. The Depth setting now determines the minimum volume you will hear with the modulation wheel rotated all the way down and Mod Depth determines how much volume will be added to that minimum value when the mod wheel is rotated all the way up. Consequently, Depth should be some large negative value and Mod Depth should be a large positive value. See the table.

(a large positive value)


The mod wheel can still control the depth of vibrato imparted to the tone by the Pitch LFO, but of course not independently. Using the mod wheel as a volume control is most useful for tones that do not require vibrato and that furthermore don't require both hands for playing notes.


Many orchestral sample libraries use the modulation wheel to control the volume and brightness of a tone by crossfading between samples. We can't do that here of course but by mixing a PCM-melody tone in another zone with a much brighter version using a Hex Layer tone in Zone 1, a very similar effect can be obtained. That is an exercise left to the reader.


Note: After selecting a Hex Layer tone configured in this way its volume may not correspond to the mod wheel’s actual position. Instead you will hear the volume at the wheel's minimum position (rotated fully down), which is typically very low. When you move the wheel even a tiny bit the volume will snap to the correct value. If you don’t hear anything when you should, just gently touch the wheel.
