Description

KQ Tixie is a 4-operator FM synthesizer for iPhone and iPad that faithfully recreates the sound and behavior of classic FM instruments from the 1980s. Experience the iconic character of vintage FM synthesis with a modern touch interface, MPE support, and AUv3 compatibility. FM synthesis generates sound mathematically rather than playing back recorded samples. Its distinctive character is heard in shimmering bells, electric pianos, basses, leads, and many of the signature sounds that defined the 1980s. 4-operator FM is not simply a smaller version of 6-operator FM. With fewer operators, sound design becomes more immediate and intuitive, making it easier to reach the sound you want without unnecessary complexity. Despite its streamlined architecture, 4-operator FM is capable of producing powerful basses, sparkling bells, rich electric pianos, cutting leads, and many of the iconic sounds that defined an era. KQ Tixie faithfully recreates the character and workflow that make 4-operator FM unique. It's not about having fewer operators—it's about a more refined design. 4-operator FM is another evolution of FM synthesis. Features - Faithful recreation of classic 4-operator FM synthesizers from the 1980s - Import SysEx data from supported hardware synthesizers and reproduce their sounds accurately - Includes thousands of patches - User-friendly sound editor designed for efficient patch creation and editing - Layer up to 8 sounds simultaneously - Supports MPE (Pitch-bend, Aftertouch, and MIDI CC#74) - Real-time performance controls for expressive sound shaping - Built-in effects inspired by the Yamaha V50 and Korg DS-8 - AUv3 Instrument support - iCloud support - Patches edited in KQ Tixie can be transferred to compatible DX-series synthesizers (excluding the DX7 and DX9), earlier EOS-series synthesizers, and the FB-01. Choose KQ Tixie if you want: - The sound of Yamaha DX100, TX81Z, V50, FB-01. - 4-operator FM synthesis with all eight operator waveforms. - Built-in effects inspired by the Yamaha V50 and Korg DS-8. - Compatibility with SysEx data from supported hardware synthesizers. Compatible synthesizers include - Yamaha FB-01 - Yamaha DX21 / DX27 / DX100 / DX11 / V50 / TX81Z / WT11 - Yamaha EOS YS200 / YS100 / B200 / DS55 / TQ5 - Korg DS-8 / 707 Names of hardware synthesizers and manufacturers mentioned in this description are trademarks of their respective owners.
