Discovery 6.4 released
Discovery is a classic virtual analog synthesizer featuring dual oscillators, multi-mode filter, gate sequencer, arpeggiator, and comprehensive MIDI control.

Version 6.4 delivers a modernized oscillator engine with reduced aliasing and improved analog character, enhanced MIDI capabilities, gate sequencer workflow improvements, and macOS sandboxing compliance.
What's New
- Oscillator Engine: Replaced oscillator engine with new, modern DSP implementation for reduced aliasing and improved analog character. Fixed PWM distortion at extreme pulse width values. Added pulse width smoothing to eliminate zipper noise during modulation. Improved FM depth range for more expressive frequency modulation.
- Output: Added output limiter to prevent clipping on hot signals in standalone app.
- Filter Display: Filter frequency LCD now shows actual Hz values (e.g. 440 Hz, 2.5 kHz) instead of a percentage.
- MIDI: MIDI channel 5 now acts as a broadcast channel, sending control data to all active layers simultaneously. Added MIDI clock tempo detection in standalone mode for accurate BPM sync without a DAW.
- Gate Sequencer: Added effect presets menu (three-dot button) with one-click gate and delay rhythm patterns. Gate cells now support click-and-drag to toggle multiple steps in one gesture. Fast mouse movements across gate cells no longer skip steps.
- GUI: LED button click areas enlarged to 18x18 px for easier interaction. Pointer cursor shown on hover over all LED buttons and the gate sequencer. Native macOS popup menus and preset rename dialog using system Cocoa controls.
- macOS: App data now stored in ~/Library/Application Support/discoDSP/Discovery/ for correct macOS sandboxing compliance.
This update is free for all Discovery 6.x customers. Discovery is available for Windows, macOS, and Linux in VST, VST3, AU, and standalone formats.
