Movement you can see, modulation you can read. Thanks as always to everyone playing and sending notes. This one is about seeing and steering the motion in your sound. New - LFO 2 is now per-voice — each held note runs its own copy, so chords shimmer and evolve independently instead of in lockstep (opt-in per route). - Motion in the partials matrix — held notes leave a live per-voice dot and fading trail, and a routed LFO traces its orbit, so you can watch modulation move the sound. - Modulation you can read at a glance — every mod source carries its own color and a tag for the module it lives in; tap the tag to jump to it. The Poly LFO now pulses at its rate in the picker. - Re-synth is now modulatable — route anything to the dry/re-synth blend. - Show help by default — a Settings toggle to keep or hide the scope's help readout. Fixed - Turning off Latch now stops the note and any noise it was making. - Tightened crowding in the Audio In panel and the top bar. - Partials hover-solo now starts off by default.

New - Poly LFO: a per-voice LFO that slowly scrubs through a frozen sound's spectrum for evolving, living pads. Choose the shape, rate, and depth, run it once per note or loop it, and route its Scrub Rate/Depth from the mod matrix. - Key Track for the sampler: play a loaded sound at one fixed pitch across the whole keyboard so a chord layers the same texture (drones, pads), or leave it on for a classic pitch-tracking sampler. - Fold now reaches below the fundamental on resynthesis for real sub-octave weight. - Save or share a preset together with its sound as a single bundle; a note marks presets that carry audio. - The spectral-freeze scrub (Rate and Depth) is now a mod-matrix destination. Improved - Redesigned Audio-In / sampler that fits one screen, with Freeze and Poly LFO up front and compact pitch controls. - A clear "Saved" confirmation whenever you save a preset, save a sample, or export a bundle. - A more playable Freeze: a lit Freeze button, an Off / 1-Shot / Loop mode, and a labelled Freeze Position. - Wider audio-file support and smoother sample loading inside a host. Fixed - More reliable free-trial and purchase handling. - Your Output level now governs the resynthesis / resonant layers. - Loading a sample no longer greys out in certain states, plus a couple of pop-up interaction fixes.

Thanks again to everyone sending feedback — one of you caught something important. Fixes • If you bought BK Harmonic before it went free, the app now correctly recognizes your original purchase and unlocks the full version automatically — no Restore, no re-purchase. (A longtime supporter reported being asked to pay again; thank you for the catch.) New & improved • During your free trial, premium modules now show a small PRO badge — so you can see at a glance which ones become a 10-second preview after the trial versus the always-free core synth. Under the hood • Sculpt bars are harder to knock out of place — a stray tap sets to 100%, and you drag past a marked unity line to push into the boost range. • "Freeze" is labelled consistently in the Audio In module. • Fixed a stray highlight that could stay lit after Overtone Scan was switched off. Keep it coming — more on the way.

Thanks to everyone who sent feedback — this update is almost all your suggestions. Fixes • Loading an audio file now works inside a host (AUv3) — the file picker was silently failing as a plugin. Fixed. (Thanks to the reviewer who flagged it.) • Sculpt double-tap is reversible — a second double-tap restores a flattened curve. • The Matrix "partials" readout now shows the real number of partials. • Expanded module pop-ups no longer close when you just miss the on/off toggle. New & improved • Report a Problem right from the app — Settings → Get Help. • Clearer free / trial status in Settings, and Restore Purchases now confirms what happened. • Brighter scope labels, and the high-contrast look is now the default. Keep it coming — more on the way.

Beat Kitchen Harmonic is now free to download. The core synth is free forever — the partials matrix, amp envelope, 400+ scale tuning, output, and full preset save & recall. Premium modules unlock with a 7-day free trial, then a one-time $7.99. No subscription. Already own the app? You keep everything, automatically — nothing to tap. New this release: • Source 2 band filter — one dual-thumb slider for lowpass, highpass, or bandpass • Freeze mod destination — sweep the Audio-In freeze point with an LFO or envelope • High-contrast accessibility toggle • Open Guidebook, Restore Purchases, and Unlock Full Version in Settings Plus a big batch of tester-driven fixes: AUv3 Key/Scale pickers work inside a host, corrected LFO2/scanner sync labels, save-safe Morph, bigger tap targets, and more. A true AUv3 — load it as a plugin in your host, or play it standalone.

Fixes and polish: - Key and Scale selectors now work in the AUv3 (running inside a host) - Bigger, easier-to-tap Gin/Tonic and Partials/Fold controls - Modulating the Sculpt Morph now works and saves correctly - Clearer LFO2 depth indicator - Smoother preset sharing

Presets are now real files you can organize. - Save sounds into folders and find them in the Files app - Open presets others share with you - Sampled presets keep their recorded audio - A cleaner Save screen - Source 2 now has its own Cutoff and Resonance filter you can modulate

Fixes for the iOS preset browser and file handling: the preset list no longer gets stuck filtered (with a clear button), the on-screen wheel no longer blocks the patch selector, Harmonic now appears when sharing audio files, and a new in-app Library browser lists your saved and imported samples. Plus the latest synth improvements.

Fixes a critical issue in 1.3.0 where the Audio Unit (AUv3) did not load in host apps and the app reverted to an older build. This update restores full AUv3 support in your DAW plus the latest features (audio record/import, expanded editor, sharing).

HD — our biggest update yet. The engine opens all the way up to 128 partials, with a zoomable editor so you can still shape a single partial by hand. New: record or import audio — capture a sound from the world around you, or load a file, straight into the harmonic engine and bring it to life as additive tone. Plus Extended Fold to blend the HD upper partials in and out, even levels across the whole keyboard, smoother pitch glides, and a classic view anytime you turn HD off.

Sculpt lets you draw the level of every harmonic by hand. In 1.2 you can hold two of those drawn spectra in an A and a B slot and morph between them: draw a bright, buzzy shape and a hollow one, then slide or automate across. That is direct control of the overtone series, one partial at a time. The rest of 1.2: - Presets are rebuilt into a real library. Search them, favorite them, file them into folders and sub-folders. Save and name your own on iPad, share one in a tap, and submit your best to be considered for the built-in set. - The modulation matrix is legible now, and you route it with your fingers: tap to connect, hold to set the amount. - The tighter editors (envelopes, sculpt, the matrix) open to a full-screen view when you need room. - A live per-partial Hz readout, a filter that now shapes the noise layer too, and an auto-gain that holds levels even across patches. Plus a round of fixes and iPad cleanup.

BKS Harmonic now works as an audio plugin. Load it as an instrument in Logic for iPad or GarageBand and play it right inside your session. It also records what you play — the on-screen keyboard and the harmony wheel send straight to your track as MIDI, notes and chords and finger-slides (MPE) included. Plus a browsable library of 400+ scales to play in, and fixes throughout. Brought to you by Beat Kitchen, your favorite music production community.
