## Oscillators

| Diva Module | Primary Hardware Emulation | Key Tonal Characteristics |
| --- | --- | --- |
| **Triple VCO** | **Moog Minimoog Model D** | Warm, fat, 3-oscillator arrangement with drift, detuning, and feedback routing options. |
| **Dual VCO** | **Roland Jupiter-8** & **Jupiter-6** | Classic 80s polysynth sound. Switchable via the *Shape* parameter: **Analog 1** mimics the Jupiter-8, while **Analog 2** models the brighter Jupiter-6. |
| **DCO** | **Roland Juno-60** / **Alpha Juno** | Digitally-controlled analog oscillator with sub-oscillator and pulse-width modulation. Clean, rock-solid pitch stability. |
| **Dual VCO Eco** | **Korg MS-20** | Stripped-down dual oscillator featuring Ring Mod and raw, aggressive wave shapes. Light on CPU load. |
| **Digital** | **Roland JP-8000** | Recreates late-90s digital technology, including the iconic **Supersaw** waveform and complex additive/buzzy timbres. |

## Filters

| Diva Module | Primary Hardware Emulation | Key Tonal Characteristics |
| --- | --- | --- |
| **Ladder** | **Moog Transistor Ladder** (Minimoog) | Creamy, rich 24 dB/oct (4-pole) lowpass filter with characteristic bass loss when resonance is cranked. Includes an added 12 dB/oct (2-pole) mode. |
| **Cascade** | **Roland Jupiter-8** & **Juno-60** | Smooth 4-pole cascaded OTA filter circuit. Toggle between **Clean** (Jupiter-8 style) and **Rough** (Juno-60 style) resonance modes. |
| **Multimode** | **Roland Jupiter-6** | Versatile state-variable style layout providing Lowpass (2/4-pole), Highpass, and Bandpass options. |
| **Bite** | **Korg MS-20** | Sallen-Key filter topology with high-resonance growl and aggressive drive. Includes toggles for **Rev 1** (raw/noisy) and **Rev 2** (tamer/cleaner) circuitry. |
| **Uhbie** | **Oberheim SEM** | 2-pole state-variable filter. Smoothly morphs from Lowpass through Notch/Band-Reject to Highpass (or switchable to Bandpass). |

## High-Pass Filters & Envelopes

* **HPF Post / Pre:** Roland-style high-pass filter blocks (as found on the Juno and Jupiter series).
* **HPF Bite:** The distinct, resonant high-pass filter stage from the Korg MS-20.
* **ADS Envelope:** Modeled after the Minimoog’s contours.
* **Analogue Envelope:** Modeled after the snappy hardware envelopes of the Roland Juno-60/Jupiter-8.
* **Digital Envelope:** Modeled after the Roland Jupiter-6 envelope behavior.
