The 1/3 and 2/3 tracking LEDs now match their labels.
Sharper black keys on the on-screen keyboard, drawn faster at any size and in dark mode. 6.6.2 Oct 5 Faster UI rendering and fixes, per-touch knob control and MENU > Program listing. 6.6.1 Aug 17 Program submenu added to the main menu, above Bank.
Fixed stuck unison voices in mono mode when changing voice count.
Lower CPU use in the editor when idle.
LED glow now matches the artwork color. 6.6 Aug 11 Added unison with stereo spread: 2 detuned voices in poly, 4 in mono and legato.
Added gate sequencer play-head that follows the current step while notes sound.
Added Show Keyboard toggle in Menu > Swap on iPad, centering the GUI when the keyboard is hidden.
Added MIDI out for the mod wheel and pitch bend graphics, sending CC1 and 14-bit pitch wheel.
Raised the voice polyphony to 32.
Presets saved before 6.5 have their chorus setting remapped to unison on load. Chorus can be switched back on independently.
UI display enhancements, minor fixes and stability updates. 6.5 Jul 28 Added universal iPhone support. Use our free KeyPad app as a MIDI keyboard, it connects to Discovery automatically via a virtual MIDI port.

Added panic on bank change to silence voices between bank switches.
Fixed PWM: smoothed mod envelope and restored PW range.
Expanded Delay/Gate tab tap areas for easier tapping on iOS.
Expanded bank list dropdown clickable area for easier tapping. 6.4.1 Mar 4 Brand new oscillator engine with analog-modeled sound. Discovery oscillators have been completely rebuilt using latest-generation DSP algorithms, delivering better bass, richer mids and highs and sharper transients with artifact-free audio across the full pitch range. Hard sync is now sub-sample accurate for tighter, more surgical sweeps.

Full PWM range restored with smooth, zipper-free modulation.
Mod envelope routing (PW, pitch, FM, noise filter) is now sample-accurate.
FM depth extended for a wider, more expressive range.
Bank switching now silences all voices instantly for clean patch transitions.
Output limiter added in standalone build for peak control. 6.4 Feb 21 Fixed AUv3 state persistence: notify host on program/bank changes so state is saved correctly. 6.3.2 Feb 18 Fixed AUv3 popup menu dialogs and native dialog actions. 6.3.1 Feb 16 Advanced DSP optimizations across oscillators, wavetables, and filters for faster, more efficient audio processing on all devices.
