GSi Model D6 is a physical modeling emulation of a Hohner Clavinet D6. INSTRUMENT BACKGROUND It was back in the fifties when German inventor Ernst Zacharias invented one of the funkiest keyboards of all times. At first the intention was to make a portable version of a harpsichord, but it soon turned into one of the most used keyboards in rock and pop music. You will certainly recognize it in the famous pop song "Superstition", and in many other funky tunes of the seventies. Many police and investigation story movies and TV shows of the 70's and the early 80's had music themes based on funky accompaniments made with the D6, a slap bass and drums. This instrument can reproduce the sound of an electric guitar and can be treated with the same effects used by guitarists (wah-wah, distortion, phaser, chorus, etc.) for both rhythmic and melodic textures, since it is actually based on a set of 60 strings and two humbucker pickups very similar to those used in electric guitars. The sound engine of GSi Model D6 comes from the exact same code that powers the GSi Gemini and the Crumar Seven as well as the Crumar Mojo 61. Some more parameters have been added to the model in order to make the instrument sound even more versatile and adjustable to personal taste. Main features: - Physical Modeling engine (no samples) - Full Polyphony (60 strings) - Authentic string sympathetic resonances - Authentic recreation of the 4 D6 filters - Two Pickups with adjustable positions - Authentic damper lever - String quality setting - Hammer Tip quality setting - Wool damper quality setting (Release length) - Responds to pitch bender (Whammy bar mod) - Responds to aftertouch (string tapping overpressure) - Built-in Wah-Wah effect modeled after the famous JH-1 pedal - Wah-Wah can be modulated by LFO, Dynamics or via Midi CC message - Built-in Phaser effect modeled after the famous Phase 90 pedal - Built-in Amplifier simulator with 5 models (Twin, JCM, AC, RJC and Bass) - Amp Distortion and pickup feedback - Built-in Stereo Delay effect - Built-in Stereo Reverb effect - Built-in programmer with unlimited Programs - Embedded user's' manual - Available as Stand-alone application and audio plugin - Very low CPU and RAM usage

KingB is designed to capture the unique tones of the B and C series tonewheel organs. It uses a fresh modeling approach to generate tonewheel signals in real time, as well as to replicate the complex interplay of components that make the organ “sing”. Absolutely no samples are used. The interplay within the intricate network of tonewheels, components, wiring harnesses, and motor elements is synthesized to a convenient set of parameters. By using them, you are able to change the quirks of the underlying organ model. This helps parallel the variances heard among individual examples of the physical instrument, and even allows replicating the effects of aging or out-of-spec electronics. The new rotary speaker emulations are a deep dive into the 3D aural candy that makes tonewheel organs truly shine. Six unique cabinet models are complemented by four amps that provide extra warmth via our “Virtual Tube” technology. An additional guitar amp bus (with three models to choose from) runs parallel to the rotary for even more sound options. A set of carefully selected pre- and post-amplification effects are integrated for good measure (and may all the measures you play be good!) Three manuals, each with its own drawbar set, as well as over 130 organ and FX parameters are MIDI controllable. You can save and share MIDI maps, sound presets, and in-app audio recordings. Factory presets include over 110 sounds varying from laid back Jazz ditties to gnarly, Purple-colored distortion extravaganzas. KingB is ready to join your workflow as an AUv3. Both the app and the plugin are universal, and also support Apple Silicon Chip computers. :: Organ :: • 91/96 Virtual Tonewheels, including 12 complex wheels • 3 manuals with own drawbar sets • Scanner chorus/vibrato • Carefully recreated “Swell” (or “Expression”) pedal • Percussion with additional user-defined parameters • Variable modeling characteristics, including tonewheel interplay, component state and more. • 12 silent-switching drawbar presets on Swell and Great manuals, MIDI controllable • Optional lower foldback • Optional keyclick with adjustable parameters • Options to emulate M and T series organs as well as B and C ones. :: Rotary & Amps :: • Six rotary cabinets with different tonal and modulation characteristics • Adjustable fast and slow speeds for both horn & drum • Adjustable acceleration and deceleration • Adjustable mic angle, distance, and balance • Adjustable stereo panning parameters for both horn & drum • Four rotary amp types, as well as bypass • DI with panning • Parallel guitar amp with three models to choose from :: FX :: • Pre-Amp FX include, — Distortion/Overdrive with EQ & Mid Boost — 10-band graphic EQ — Wah with optional auto — Chorus/flanger with variable rate & depth — Tape delay emulation with self-oscillating feedback — Spring reverb • Post-Amp FX include, — Compressor with threshold, ratio, attack, and decay. — 15-band graphic EQ — Parametric reverb with 7 room types, pre, decay, and tone. :: Admin Stuff :: • Also runs as AUv3 • DAW-friendly fluid layout • Fully configurable MIDI key split, even allowing overlays • Easy MIDI learn, with ability to manually configure each MIDI parameter • 130+ MIDI parameters • MIDI map save, share, preset linkage • Velocity control for keyclick, amplitude, and percussion • Lockout mode for organ modeling settings & MIDI prefs • Create, save, and share unlimited banks and presets • 110+ factory presets • Stand alone app: audio recording & sharing • Compatible with Apple Silicon computers

Verdict
The clearest difference is in-app purchases: Model D6 at none against KingB Organ's 3. Model D6 also leads on price ($19.99 vs $24.99) and iOS requirement (11.0 vs 15.6). KingB Organ's advantage is update cadence (every 4 months vs every 9 months) and ratings volume (27 vs 5). On rating, ads, monetization model and device support there is nothing between them.

Model D6 costs $19.99 and KingB Organ $24.99 up front. KingB Organ sells 3 one-off in-app purchases. Model D6 asks for nothing beyond the download.
Model D6 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: KingB Organ has 27 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 67% of Model D6's written reviews are positive against 75% of KingB Organ's, so the app with the better star average is not the one people write more warmly about.
Model D6 ships an update every 9 months, KingB Organ every 4 months. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
