===============================================================================
24SS / 24SuperSynth v0.2.0
Eight-Voice Polyphonic Semi-Modular Virtual-Analog Instrument
===============================================================================

Developed by Marko Damjanovic (MARCOD)
24REC Studio / Italy / 2026

24SS is an original eight-voice polyphonic synthesizer for Windows. It combines
the direct workflow of a classic patchable instrument with a modern preset
system, sample-accurate modulation, a host-synchronised sequencer, and a
photoreal 24REC hardware-style interface.

This is an independent 24REC design. It does not reproduce another company's
logo, panel artwork, trade dress, source code, or factory preset library.

-------------------------------------------------------------------------------
INSTALLATION
-------------------------------------------------------------------------------

VST3

1. Extract the downloaded ZIP archive.
2. Copy the complete "24SS 24SuperSynth.vst3" folder to:

   C:\Program Files\Common Files\VST3\

3. Restart your DAW and rescan VST3 instruments if necessary.
4. Create an instrument track and load 24SS / 24SuperSynth.

Standalone

Run "24SS 24SuperSynth.exe" directly. Select the required audio and MIDI
devices in the application's audio settings.


-------------------------------------------------------------------------------
SIGNAL PATH
-------------------------------------------------------------------------------

MIDI CV -> DUAL VCO + SUB/NOISE -> SATURATING MIXER -> 24 dB LADDER FILTER
        -> VCA -> HPF -> REVERB -> OUTPUT

The normalled routing works immediately without patch cables. MIDI pitch feeds
both oscillators, MIDI gate drives the contour, the contour opens the VCA, and
the envelope amount control modulates the filter. Patch cables add or replace
modulation routes and are saved with the host project and presets.


-------------------------------------------------------------------------------
SYNTH ENGINE
-------------------------------------------------------------------------------

  - Eight independently allocated polyphonic voices
  - Two band-limited virtual-analog oscillators per voice
  - Saw, pulse, square, and triangle waveforms
  - Sub oscillator and noise source
  - Pulse-width modulation and oscillator hard sync
  - Subtle per-voice oscillator tolerance and analog drift
  - Saturating analog-style mixer with drive
  - Nonlinear four-stage 24 dB transistor-ladder low-pass filter
  - Resonance, envelope amount, and keyboard tracking
  - Hardware-range ADSR contour and voltage-controlled amplifier
  - Audio-rate-capable LFO, sample and hold, and attenuverter
  - High-pass utility filter, glide, stereo reverb, and output control
  - Velocity, pitch bend, overlapping releases, and voice stealing
  - Per-sample MIDI boundaries and sample-accurate modulation where required


-------------------------------------------------------------------------------
PATCH CABLES
-------------------------------------------------------------------------------

Drag from an output jack on the left side of the patch field to a compatible
input jack on the right. Valid destinations illuminate while dragging.

Right-click an input jack to remove its routes.

The cables use shaded Bezier rendering, natural sag, depth highlights, and
smooth drag animation. Every connection affects the sound and is stored in the
plugin state, factory preset, and DAW project.


-------------------------------------------------------------------------------
CLOCKED SEQUENCER
-------------------------------------------------------------------------------

The 16-step sequencer follows host tempo and stores its pattern with each
preset. Use RUN SEQUENCE to enable it, choose the rhythmic division, then set
the number of active steps and gate length. Factory sequences provide musical
starting points for trance, acid, techno, and arpeggiated sounds.


-------------------------------------------------------------------------------
FACTORY PRESETS
-------------------------------------------------------------------------------

The factory bank includes 31 sounds across these categories:

  Utility Init          Acid Wobs             Rumble Bass
  Tech House Bass       Dub Stabs             Hypnotic Techno
  Raw Techno            Minimal / Deep Tech   Percussive Synth
  FX / Noise            Trance Sequences      Arps
  Leads                 Pads

Several presets use visible patch-cable routing. Multiple Acid Wob variations
and musical Trance Sequences are included.


-------------------------------------------------------------------------------
QUICK START
-------------------------------------------------------------------------------

1. Play a MIDI note or chord; the normalled signal path is already active.
2. Choose oscillator waveforms and octave ranges.
3. Balance VCO 1, VCO 2, SUB, and NOISE in the saturating mixer.
4. Use the large FILTER control to set the tone, then add resonance and contour.
5. Shape the sound with ATTACK, DECAY, SUSTAIN, and RELEASE.
6. Drag a modulation cable into FILTER, pitch, PWM, VCA, or LFO rate.
7. Choose a factory preset or run a clocked sequence for an immediate starting
   point.


-------------------------------------------------------------------------------
SYSTEM REQUIREMENTS
-------------------------------------------------------------------------------

  Operating system: Windows 10 or Windows 11, 64-bit
  Plugin format:    VST3 instrument
  Host:             64-bit VST3-compatible DAW
  Processor:        Modern x64 processor
  MIDI:             Required for pitched performance


-------------------------------------------------------------------------------
CURRENT LIMITATIONS
-------------------------------------------------------------------------------

  - Patch depth defaults to 65%; per-cable depth editing is planned.
  - Reverb is an original feedback-delay ambience, not spring convolution.
  - Sequence notes are stored in presets/state; a full front-panel note editor
    is planned for a later update.
