ImpactForge builds hits like the ones in movie trailers: for the chorus entrance, the drop or the end of a riser. Every note is one hit made of three layers. Boom is a deep sub that starts high and dives down — Pitch Drop sets how far, Drop Time how fast. Click adds a sharp transient that cuts through the mix, and Noise Tail adds noise with a closing filter, rumble and small debris. Size lengthens the whole hit and enlarges the room, Reverb sets how much of it you hear, and Tone and Drive brighten and thicken the sound so the boom comes through even on a phone. Tune sets the boom pitch on C3 and other keys play higher or lower, so the hit is easy to tune to your track. Velocity changes level and brightness. The display shows the shape of every layer, a playhead for the last hit and the pitch-drop curve. Everything is synthesized — no samples — so every hit can be shaped to fit your song.
