Mastering.com breaks down how Alchemy's effects routing works in Logic Pro, using global sends to add reverb across every oscillator in a patch.
The blend knob between filter one and filter two does double duty: it controls tone, but it also decides how much signal from each filter reaches its paired effects slot.
Dialing that knob fully toward one filter sends everything there, while splitting it halfway blends both filtered signals into the effect at once.
For more surgical routing, a single oscillator can be sent through its own filter and into a dedicated delay, letting you shape that one source's tone independently while the rest of the patch stays untouched by the effect.
