Tokøta from Mastering.com walks through Alchemy's voice architecture in Logic Pro, covering keynote mode and the voice count settings that shape how a patch responds to your playing.
Keynote mode determines whether every key triggers its own pitch or collapses to a single note, useful for testing loops or simplifying a patch.
Voice count controls polyphony, from a single voice for clean basses and leads (where notes naturally overlap and cut each other off) up to 32 voices for full chords or dense arpeggios. Voices can be set independently per source or globally.
Switching to Legato mode usually drops voice count to one and smooths the transition between notes by removing the attack pop, giving a more connected, played-in feel.
