KQ Tixie vs MBR

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. 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.
