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

CRATE is a sampler you talk to. Type or say a vibe — "dusty boom bap with rhodes", "NewJeans type beat", "dark plugg with bells" — and in a second the pads fill with drums, a chopped sample and a bass line, already playing. Then shape it the way producers do on an MPC or an SP-404, just faster. MAKE A BEAT IN SECONDS • Describe a beat and CRATE builds it from its sound library: drums, chops and bass in key. • Ask for changes in plain words — "add a sax line", "more hats", "punchier snare", "clear the bank". Only that part changes. • Drag a pad down and say what you want there. Swipe a pad left or right for another sound, up to remove it. PLAY IT LIKE A SAMPLER • 16 pads in four banks, a step sequencer and live recording that lands on the beat. • KEEP JAM saves what you just played over the loop. • Punch-in effects: hold FX and an effect pad, higher = more. • Sample from the mic straight onto a pad, or import a song and chop it into 16 pads. CHOP AND FLIP • Auto-chops land on real attacks, on the grid. • FLIP re-sequences the chops into something new while the drums keep playing. • Per-pad level, filter, attack, release, reverse, key shift and time stretch. FINISH THE SONG • Arrange intro, verse, hook and outro from your patterns, or let ARRANGE do it in one tap. • Change tempo, swing and key; export the song as audio to share. MADE FOR IPHONE DUO • On iPhone Duo the hinge is an effect: fold to build tension, snap open for the drop. The outer screen keeps the beat in view when it's folded. • Works great on iPhone and iPad too.

Verdict
The clearest difference is price: CRATE at Free against Model D6's $19.99. CRATE also leads on update cadence (daily vs every 9 months). Model D6's advantage is ratings volume (5 vs 1) and iOS requirement (11.0 vs 26.0). On rating, ads, in-app purchases and device support there is nothing between them.
