This Ableton tutorial walks through Meld's breakout view, where velocity, MPE controls, and cross-engine modulation can all be configured in one place. The presenter maps MIDI velocity to an oscillator macro, then edits clip velocities in real time to show how dramatically the mapping shapes the sound.
Switching to engine B, MPE pressure gets routed to both filter frequency and panning, with the MPE tab used to dial in the effect live. The result shows how touch-sensitive expression can move beyond pitch and slide into timbral and spatial control.
Mappings can be copied between engines or cleared instantly, keeping the workflow flexible. An LFO living in engine B can modulate parameters in engine A via the cross-modulation tab, so the two engines aren't isolated sound sources but interconnected layers that can shape each other.
