Part of Sonicware's excellent Liven groovebox series, the XFM is a modern take on classic digital FM sounds, offering a choice of intuitive and quick sounds or logical and deep programming. Supplier's Notes: Classic FM sounds, effortlessly merged with FM FUSION. Using the 4-track sequencer and presets, you can construct an entire song. Three Fusion FM Engines X-LAB Engine Merge two FM sounds with a single knob to create a completely new sound. XFORM Engine Transform one FM sound into another over a specific period of time. X-LFO Engine Continuously transform between two FM sounds using an LFO. Over 300 Inspiring Preset Sounds Ready-to-use presets including, leads, keyboards, strings, winds, basses, pads, chords, drums, and sound effects. Two approaches to FM sound design Intuitive and Quick Merge and sculpt FM sounds with a single, intuitive, knob turn. The X-Lab engine merges two FM sounds by smoothly blending their envelopes, modulation routing, and feedback. The X-Lab algorithm can merge sounds with radically different FM structures and overtones, all without losing the fundamental tuning of the sound. Pitch locking can also be turned off to create brilliant atonal transitions between FM sounds. Merged sound can then be saved, recalled, and merged with additional FM sounds. This is called merging process FUSION FM. Logical and Deep For those who want to dive into the FM Engine, the EDIT mode and included overlay provide full access to the innovative 4-OP XFM engine. 15 knobs and 30 buttons provide quick and intuitive access to all FM parameters. Explore FM synthesis without the conventional menu diving and head scratching. 4-Track Step Sequencer Perfect for song production and live performance Manage lead, bass, rhythm, and more, each on separate tracks. Sequence up to 64 steps per pattern. Save up to 128 patterns. The parameter locking function allows you to record knob changes into your patterns. This automation function can be recorded live, or programmed in step by step. Sub-divide the tempo down to 32nd notes for higher resolution sequencing. Sequence longer notes across several steps, AKA Tied Notes. Specifications: Size 297mm (W) x 176mm (D) x 48mm (H) 11.7 in (W) x 6.92 in (D) x 1.89 in (H) Weight: 790g/1.74lb.
