MALLET INSTRUMENT

Heartwood

Wood, bronze, and electric color. Shape the strike, let it ring, and find a voice of your own.

Pass 5 · a contact strike you can hear, fuller bars in every register, and a small room.

PLAY

Try the bars

Press or hold a bar, or play the letter keys. Choose Ring to let notes decay after release, or Damp for a held-key instrument. Hold several for chords. Shift makes a harder strike.

Ring length5% gives a tight hit; 100% keeps the voice’s original decay. Works in both Ring and Damp modes.Fade-in0 ms keeps the strike. Increase for a softer entrance; very short rings may fade before a long entrance completes.Release after key-upIn Damp mode, how quickly a released key or sustain pedal quiets the note. Ring mode ignores key-up; Stop always damps quickly.Bar profile Shallow → waisted → offset. Derived from the Aftertouch beam solver. Mallet softness Sets how long the head stays on the bar: about 0.2 ms when hard, 3.4 ms when soft. A longer contact filters the upper tones. In pass 5 a harder strike shortens the contact, so it brightens as well as gets louder. ImpactThe click and short contact noise of the head meeting the bar. Pitched lower and longer for soft heads. Pass 5 only. Strike position Where the mallet hits: 0% left end, 50% center, 100% right end. This changes which ringing components are excited. Strike coupling Let strike position shape the tone. Quiet spots retain some main note so the bar stays playable; softer heads spread the contact. Resonator body Dry bar → hollow body with a warm bloom and longer tail. In pass 5 the tube exchanges energy with the fundamental only, so the bar’s overtones keep their level; a harder strike makes the body more hollow. Natural damping Controls how quickly the tone falls away. Follow beam shapeAuthored tuning → calculated beam ratios. Pitch lock keeps the root steady.Upper tone presenceBring the ringing components forward; hear more of the profile and strike position. Neutral at 50% in pass 5.Upper tone decayShort bright edge → lingering shimmer. Center preserves the original decay balance.Bronze beatingStill → shimmering pair. Active for Bronze pair.Digital strikeGentle → bright FM attack. Active for Digital mallet.Strike strength For mouse, touch and ordinary key presses.RoomSend to a small wooden hall, about one second long. Damp lets it ring out; Stop silences it. Exported WAVs include it.Stereo spreadLow notes lean left and high notes right, as if you were standing at the bars. 0% is mono.

Use pointer height as strike position Keep notes in tune as the profile changes Original Silver bell ratios

Sound edits apply to the next strike. Pointer height runs from 0% at the top to 100% at the bottom. Keys and MIDI use the Strike position slider.
