MULTI KEYS
A one-shot sampler you play like keys. Every press pulls the next sound from 151 of Keyon's own one-shots, so no two notes land the same way - and it never leaves the key.
Free. Sign in, check out at $0, and the download waits in your account.
Three pools of one-shots
Every key press pulls the next sound from a pool - 151 factory one-shots or your own. Each pool has its own MACHINE: WARM, GRIT or 8-BIT for an old sampler's sound, or CLEAN.
Variation that stays in key
AMOUNT sets how much each press differs: a few cents of pitch, sample start, level, pan and tone, plus a chance of REVERSE or an OCTAVE. With the song playing, a bounce matches the playback.
Keep a take
Press an empty TAKE key to keep what you are hearing: every key replays the sound and variation it last played, until you press it again. Four takes, switchable live.
Chords from different sounds
With ENSEMBLE on, notes you strike together each take a different sound from the pool, so a chord is a blend of sounds instead of one sound stacked.
One filter, then drive
All three pools go through one filter, then DRIVE. It starts fully open: turn CUTOFF down to darken the sound, and ENV sweeps it on every note, up or down.
Mono lines that glide
In MONO, a note played legato moves the sound already playing to the new pitch instead of pulling a new one. GLIDE sets how long the slide takes.
