SubForge 1.3.0

A feature release: three new controls for shaping the square wave (Width, PWM and Sag), six new presets that use them, and finer control of every knob. CLAP and VST®3 plug-ins for Linux and Windows; copy SubForge.clap and/or the SubForge.vst3 folder from the archive into your plug-in folder, as described in INSTALL.txt.

Downloads

• SubForge-linux-x86_64.tar.gz for Linux (x86-64)
• SubForge-windows-x64.zip for Windows (64-bit)

What's new

• Width. Set how long the square wave stays high, from 10 % to 90 %. 50 % is the plain square; a few percent off-centre gives a rawer, more nasal sound.
• PWM. Let the LFO sweep the width of the square for the classic moving, chorus-like pulse sound. It follows the LFO's sync, rate and shape.
• Sag. Let the flat tops and bottoms of the square lean towards the centre, like a classic acid square. The slope follows the pitch, so it sounds the same across the keyboard. Most audible with Drive or distortion.
• Six new presets, last in the list: PWM Slow Sweep, PWM Free Chorus, PWM Acid Roll, Sag Square Bass, Sag Acid Diode and Off-Centre Acid.
• Fine adjustment. Hold Shift while dragging any knob to change it in tiny steps. Width shows one decimal.
• Right-click steps back. On the sequencer's Rate, Steps and Root chips, a right-click counts down; the left button still counts up.

Width, PWM and Sag only affect the SQR wave and are greyed out for the others. Randomize and Mutate know about them.

A tidier OSC panel

• The sub oscillator's shape is now two chips (SIN, SQR) furthest right in the OSC title row, behind a "SUB" label, so there is room for five knobs.
• The LFO panel is simply titled "LFO".

Compatibility

• Projects and presets from earlier versions open and sound exactly as before. Width, PWM and Sag start at 50 %, 0 % and 0 %, which is the old sound.
• The new presets need 1.3.0 or later to sound as intended.
