Discovery Pro extends Discovery with a sample/wavetable engine, unison, 128-voice polyphony, PADsynth re-synthesis, three extra oscillators, 16 filter types, and 5,000+ presets across 100 banks.

Includes a standalone application, graphical mod envelopes, scalable GUI, octave key split, aftertouch, XML MIDI board templates, zone presets, Nord Lead 2 SysEx import/export, and MTS-ESP micro-tuning.

Oscillator and filter code is hand-optimized for x86 and Apple Silicon.

8.17 adds dual-core voice processing: when active voice count crosses a threshold, voices split across two cores. On heavy patches (many voices, oversampling, deep modulation) per-core load drops by about half and you can sustain roughly 2x the polyphony before voices drop. Light patches stay single-core, so there's no overhead for simple work.

The Super 7 oscillator runs the Roland JP-8080 supersaw — one master saw plus six detuned saws — for trance leads and pads that sound like the source.

The Pulse Width knob sets the detune spread, from string-chorus subtle to full supersaw. PW is a regular mod destination, so LFO and the mod envelope can drive it. Phase is selectable between random-per-note (the JP-8080 default) and retriggered (consistent attack).

Stacks with Unison if you need it bigger. A green LED on the SAW button marks Super 7; blue marks Parabolic.

8x oversampling on the live engine with IIR/FIR filtering for low aliasing without the latency cost of brute-force upsampling. Bounce settings switch to 16x for higher-quality offline renders.

An arpeggiator mode driven by a probability matrix that updates as it plays. Each note influences the probability of the next, so the output drifts along instead of jumping randomly between unrelated notes.

Reads the octave-range parameter for vertical motion. Useful when you want pattern-like material without committing to a fixed sequence.

• Oscillators: 12-bit resolution (up from 9-bit) and 2x larger wave lookup tables — less quantization noise, smoother high register.
• Distortion modes: 4x internal precision.
• Filters: several models retuned for closer analog response.

• Disk Mode: browse presets directly from Documents > discoDSP > Discovery Pro > Presets > Programs instead of the bank/program grid. Click the BNK letter on the LCD to toggle between Bank and Disk modes. File-based preset export lives in the Edit menu.
• Preset library: expanded factory content.

PADsynth renders WAVE waveforms and imported audio into looped, evolving textures — useful for pads, ensembles, choirs, and bells without recording or layering them by hand.

4-sample fade-in/out at the loop boundary removes the click rendered versions used to have. Render time goes up to 24 seconds (from 6) for longer source material.

Output is written as SFZ with loop_mode=loop_continuous tags, so the rendered samples drop into any SFZ-capable sampler with the loops preserved.

Nord Lead 2-modeled unison, calibrated against the hardware in Polyphonic and Legato/Mono modes.

All Nord Lead 2 detune modes are available.

Three window sizes: 1x (400p), 1.5x (600p), 2x (800p). Rendering is optimized at every size.

Drop WAV (16/24-bit), SoundFont 2.04 (SF2), or SFZ files into DWB banks. Uses high-quality sinc interpolation, so resampled tones stay clean across the keyboard.

Zero-delay feedback filters modeled on the Nord Lead 2.

Moog Ladder 24 dB and 12 dB use trapezoidal integration with 4-stage tanh nonlinearity. Oberheim SEM comes in Classic and Raw variants with semitone-scaled frequency. Combined with Discovery's original 8 filters, that's 16 types in one slot.

Adaptive Filter Slope switches between 12 dB and 24 dB based on MIDI note and velocity — steeper on low notes for tighter bass, gentler on high notes to keep brightness, steeper on hard velocity in the mids. Works on every filter, including the Nord Lead 2, Moog Ladder, Oberheim SEM, and Phaser (adaptive tap count).

Click-and-drag to draw time-synced mod envelopes. Free-shape, not stage-based, so you can sketch a curve instead of dialing five segment parameters.
