The Mela 4.4 update brings 2 new modules. The new VPS Oscillator module uses the Vector Phaseshaping synthesis algorithm, which is a generalisation of the classic Phase Distortion (PD) method. With its Skew and Formants parameters, you can create a lot of interesting waveforms.

When the Formants parameter is set to 50% the module behaves like a classic PD oscillator. Setting Skew closer to 0% or 100% turns the sinusoid into a saw-like shape. When the parameter value is very close to these extremes you may hear some aliasing. The aliasing could be considered part of the appeal of the classic PD sound, so experiment with it to taste. You can also use the Key Track as a modulation source to deal with aliasing for higher-pitched notes.

When the Formants parameter is set to a value closer to either 0% or 100% the waveform shape becomes pulse-like. Modulate the Skew parameter to achieve the PWM-style effect. When the Formants parameter value is above 100% you will start hearing formants as the module starts squeezing more sinusoid cycles in a single oscillator cycle. Modulate the parameter for interesting effects.

The module’s graph displays the waveform the oscillator is generating. It responds to the horizontal and vertical drag gestures to control the Skew and Formants parameters. The dashed line behind the waveform shows how the phase of the sinusoid is distorted. The line starts at the 0% phase and ends at 100%. When both the Skew and Formants parameters are set to 50%, the line is straight, indicating that the sinusoid is not distorted. Adjusting either of these parameters creates a breakpoint, introducing phase distortion. The Skew and Formants parameters set the (x,y) coordinates of the breakpoint.

The new MIDI Capture module records all incoming MIDI messages into a MIDI file that you can drag and drop into the host or the Files app. The module is especially useful when you have a complex MIDI processor chain in your host or Mela that you want to render into a plain MIDI file for further editing.

Other Changes:

• Improved the waveform generation algorithm for the VA Oscillator module.
• Oscillators now only reset their phases on non-legato note-on events.
• Intensity dials’ drag gesture behaviour reverted to be consistent with the other dials. i.e. to change the value of the parameter you need to perform a vertical drag gesture.
• Renamed the Logger module to MIDI Logger.
• Updated the Getting Started with Mela document.
• Added new presets.
