feldman-field

feldman-field sinks every velocity into a whisper.

Morton Feldman kept whole evening-length pieces at the edge of audibility, a dynamic world so compressed that a mezzo-piano counts as an event; this is that field as a compressor for touch. Each note-on velocity is mapped linearly from the full 1..=127 down into floor..=ceiling, then nudged by a seeded jitter of up to jitter either way so the surface still breathes. Your shaping survives in miniature: what you played loud is still the loudest thing in the room, but the room now tops out at a murmur.

The jitter follows its seed: the same seed gives the same field forever; see Seeds. Note-offs and everything else pass untouched.

Parameters

Parameter	Type	Default	Range
seed	integer	0	any unsigned 64-bit value
floor	velocity	8	1..=127, at most ceiling
ceiling	velocity	28	1..=127
jitter	integer	4	0..=20

Example

miditool.kdl

input "Roland"
output virtual="miditool Out"

feldman-field seed=6 floor=6 ceiling=24 jitter=3

Play however you like; it all comes back between a breath and a murmur, faintly alive.

Try this

Build the whole late-Feldman room. Long dealt durations, the whisper field, and one permitted disturbance a minute:

duration-lottery seed=5 mean="2s" min="500ms" max="8s"
feldman-field seed=6 floor=6 ceiling=22 jitter=3

Then set jitter=0 and floor=15 ceiling=15 to flatten the field completely: every note identical, and all the music left in where you place them. Or follow the field with anti-accent at a level below its band, so that within the whisper one note per window is allowed to stand slightly taller than the rest.
