## KQ Tixie 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.

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.

## KQ Tixie Reviews in United States

### ***** "81Z has arrived"
I’ve been waiting for an emu of one of my favorite synths, a 4-op FM rack mount from 1986. And this is it! It also has a lovely UI that makes programming much easier than the original and a lot of additional features and improvements. Thank you!

### ***** "Very helpful and patient developer"
The developer was very nice in their response and tried to offer some help. Therefore I’m upgrading my rating to 5 stars. I like the sounds but the navigation and files management could be better.

### ***** "FB-01 Heaven"
Ryouta Kira nails the oft maligned FB-01 (and the TX-81Z) with this app. Minimalist and beautiful. Now, if KQ could reproduce the TX802 with its Performance Mode (which no one has to date, on any platform), all would be right with the world. Well, almost. Well done!
