Classic FM sounds, effortlessly merged with FM FUSION

Easy morphing of complex FM sound algorithms
XFM has three new FM fusion engines that the complex algorithms of FM sounds can be morphed to create sounds.

• X-LAB: Merge two FM sounds with a single knob to create a completely new sound.
• XFORM: Transform one FM sound into another over a specific period of time.
• X-LFO: Continuously transform between two FM sounds using an LFO.

Parameter locking can record your tweaking knobs

• Parameter Lock: You can easily record knob motions by moving a knob of the synth parameters.
• Sound Lock: You can play a different sound for each note. XFM is a 4-track / 6-voice synth, but using these functions you can create an almost infinite variety of tonal expressions.

Chance Music features

• Note Probability: You can set the probability of each note sounding from 25 - 100%.
• Randomizing Phrases: You can randomize phrases by beats or bars.
