Yumtone H4

Soundiron Yumtone H4 brings the distinctive FM tones of Yamaha’s 1987 Electone HC-4 into a playable sample library. Recorded in wide stereo and through direct line input, its collection spans sustained synth voices, staccatos, piano, vibraphone, bells, drum hits, key effects and tempo-syncable rhythm loops. You also get 20 evolving ambient pads and 20 custom FX presets, offering starting points for atmospheric scores, retro electronic tracks and textured pop arrangements. Shape each part with attack and release controls, vibrato, octave layering and glide for flowing leads. An adaptable LFO, 13 filter options and a customizable arpeggiator with velocity sequencing add movement and rhythmic variation. Yumtone H4 suits producers and composers who want vintage digital character with hands-on sound shaping, whether they’re building a melodic hook or an evolving backdrop.
