The same hands
REISEI, and everything that follows it, is built by an industrial and UI designer who also mixes and masters. The sound and the interface come from the same hands, so nothing is lost in translation between how a tool works and how it feels to work in.
Not a luxury interface
This is a working instrument, not a showroom. Every control earns its place: only what you need, and all of what you need, with nothing surplus standing between you and the decision.
Nothing ships on impression
Every change is checked against a suite of automated acoustic tests: complementary band splits that recombine without comb artefacts, widening that nulls exactly on a mono fold, phase coherence, and perfect stillness in silence. Every build passes Apple's auval -strict.
The standard
One line decides what goes in and what is cut: would a top engineer still trust this in fifty years? If the answer is no, it does not ship.
