Does this thing have a patch browser yet?

no. nothing modern. just the list that pops up when clicking in the preset/bank box

Discovery Pro 8.9.4

Version 8.9.4 resolves critical macOS Standalone filter selection issues, expands preset randomization capabilities, and refines MIDI output functionality for improved stability and compatibility.

macOS Standalone Filter Selection Fix

• Fixed filter type selection corruption in macOS Standalone where automation callbacks were overwriting user selections with incorrect values
• Disabled automation system calls for filter type parameter changes on macOS Standalone while preserving normal automation for plugin formats (AU/VST/AAX)
• Affects filter type popup menu and prev/next navigation buttons on macOS Standalone only

Preset Zone Randomization Expansion

• Extended preset randomization to support all zone types instead of only GATE and MOD_GATE presets
• Added individual randomization functions for LFO1, LFO2, MOD, OSC, PAN, AMP, FILTER, DELAY, and WAVE_GATE zones
• LFO1 randomization covers waveform, destination, rate, and amount parameters
• LFO2 randomization includes arpeggiator settings, destination, rate, and amount
• Oscillator randomization affects waveforms, modes, tuning, and mix settings
• Filter randomization encompasses filter type, envelope, frequency, and resonance parameters

MIDI Output Refinements

• Fixed uninitialized midi_out and midi_out_cc_feedback boolean values in constructor that caused AU format layer initialization issues
• MIDI Out now exclusively available for VST2/VST3 formats with AAX/AU remaining disabled

Discovery Pro 8.10



New Features

• 16x Oversampling for Offline Bounce: Maximum audio quality option for final renders
• Mono Mode Priority: Control which note plays when triggering chords in mono/legato mode: Last Note (default), First Note, Lowest Note (ideal for bass), Highest Note (ideal for leads), or Random Note. Available in Voices Config popup.
• Voice-Based Panning: Per-voice panning mode where each note in a chord gets its own pan position based on individual velocity, creating natural stereo spread. Each voice maintains independent LFO phase for animated stereo movement. Toggle available in PAN preset menu.
• Classic Filters Toggle: Layer-level control to switch between Modern filters (default, smoother sound) and Classic filters (legacy algorithm with hard clipping for vintage character). Affects LP12, LP24, HP12, HP24, BP24, BR24, and Formant filters. Available in filter popup menu.

Performance & Stability

• Significant CPU Optimization: Intelligent silent block detection reduces idle CPU usage from 10% to 2% with high oversampling. Uses 2-second timeout to preserve delay tails and release envelopes.
• LFO & Gate Timing Sync: Master sample clock ensures LFOs and gate sequencers stay perfectly in sync during idle optimization periods.
• HiDPI Display Fixes: Proper scaling for all dialogs, popups, and menus on Windows at 125%, 150%, and 200% DPI settings. Standalone and plugin builds now render correctly on high-resolution monitors.

Platform Improvements

• macOS: Plugin data now stored in ~/Library/Application Support/discoDSP/Discovery Pro/ following Apple guidelines
• Windows: Updated to native Segoe UI font, compiler migrated to Visual Studio 2022
• Linux: Robust font fallback system (DejaVu Sans, Liberation Sans, Nimbus Sans, FreeSans)
• MIDI Out: Now available for VST2/VST3 formats with improved initialization

Picked this up. Sounds great.

Sounds great but awfully spendy!

Discovery Pro 8.11



New Features

• JP-8080 Super 7 Supersaw: Classic Roland JP-8080 supersaw algorithm with seven stacked sawtooth oscillators for massive trance leads and pads. Pulse Width knob controls detune amount from subtle chorus to full supersaw spread. LFO and Mod Envelope modulation via PW destination for animated timbres. Green LED indicator distinguishes Super 7 from Parabolic mode. Available on both OSC1 and OSC2.
• Real-Time Oscilloscope Display: Stereo waveform visualization in voice counter area with LED glow effect and dynamic brightness based on signal level. Skin-aware color theming with configurable ARGB colors. Toggle via Edit > Appearance > Oscilloscope menu.
• Master Volume VU Meter: Real-time output level visualization on master volume knob using green LED indicator.
• Modulation Indicators: Green overlay indicators on Pulse Width, FM Amount, AMP Gain, Wave Semitone, OSC2 Semitone, Filter Cutoff, and Pan knobs showing LFO/ModEnv/Mod Step modulation. Real-time envelope position display on all AMP, VCF, and Mod envelope ADSR knobs.
• Voice Note Panning Mode: Third panning option that positions notes in stereo field based on MIDI note number (low notes left, high notes right). L/R controls center note across full MIDI range with Amount controlling stereo separation. Rate adds dynamic drift LFO for evolving stereo movement with optional tempo sync.
• Gate Sequencer Note Retrigger: Four-state gate sequencer supporting Off, Gate On, Retrigger, and Gate+Retrigger per step. Full voice note-off/note-on cycle on retrigger steps for hard envelope restarts and dynamic rhythmic articulation. White circle UI indicator displays retrigger-enabled steps. Right-click toggles retrigger state independently from gate state.

Arpeggiator Improvements

• Fixed first arp note delay when pressing a key after 2+ seconds of silence with tempo-synced arp rates
• Gate retrigger now triggers arpeggiator notes immediately instead of waiting for next sample cycle
• Fixed Markov arp mode double increment bug that caused erratic step advancement
• Proper arpeggiator step advancement in gate retrigger for all modes (down, up&down, up, random, rand2, Markov)

Workflow Enhancements

• VA Oscillator Switch submenu added to OSC preset dropdown for quick access to Free Running, Phase Reset, and Off modes
• Command+double-click resets morph sense to zero on all aftertouch sense knobs
• Sense edit mode inverts Command key behavior for consistent sense/value editing workflow
• Mod sequencer value input changed from Ctrl+Click to Shift+Click for more intuitive modifier usage
• Native macOS dialog integration for mod value input
• Improved LFO/gate timing synchronization during idle CPU optimization with phase compensation

Performance & Optimization

• Assets Pack System: New VPAK format packs all skin files into single Assets.pack file per skin for smaller installer size and faster loading
• Per-skin image caching for faster subsequent loads with thread-safe pack access
• Automatic fallback to Default skin when selected skin's pack is missing
• Dynamic wavetable decimation support for runtime size optimization using half memory with 2x-16x oversampling
• Reduced GUI memory spikes through voice counter caching and optimized repaint handling

Thanks for the latest updates! Many new feastures and improvements in short update cycles! Very nice of you!

I have an issue with the latest version 8.11.3 though (I can safely reproduce it every time):

In Image-Line's FL Studio I cannot unload the VST3 version of Discovery Pro. It fails to unload the Discovery Pro VST3 instance or it fails to close FLStudio at all. So something bad happens during unloading. FL Studio freezes and the executable process must be killed. No other workaround found so far. Previous versions worked fine. So something with the latest update maybe? If you need more detailed issue repro steps, please message me.

Discovery Pro 8.11.4



Bug Fixes

• VST3 Unload Fix: Resolved issue where closing Discovery Pro VST3 or shutting down the host would cause freezing, requiring forced termination. The GUI optimization in 8.11.3 introduced a static image cache that wasn't being cleared on plugin unload, preventing proper cleanup.

Thanks for quick update. I checked the version (in Discovery Pro Menu). It says 8.11.4. Unfortunately the issue is still there in FL Studio.
