Penumbra 1.0

Penumbra 1.0
A space-drone instrument for the M-VAVE FM-1, by Lunar Eclipse Forge. Switch it on and the drone swells in; you play over it, loop it, shape it and move it from place to place.

Package: penumbra-1.0.fwsc, identity FM-1_73010000. It carries the update loader: you can always leave Penumbra again, for another firmware or M-VAVE's own.

What is in it
DRONE: five voices on the black keys, held on the scene's pedal. A new scene moves only the notes it must, one voice at a time, sliding slowly. Each voice HELD or SWELL (it comes and goes).
VOX: the white keys, a four-voice synth far back in the shimmer. Four sounds on black keys 8-11 (GLASS, REED, HALO, LOW): wave from saw to a narrow pulse, low-pass to band-pass, glide.
PULSE: a deep kick tuned to the key (black 6) and BLOOM, a slow swell in the key (black 7).
TEXTURE: a bed of space wind.
The looper: REC records VOX and PULSE on the clock, in layers; PLAY stops or plays (held: undo, with ALGO: half or double speed). It follows the scene's key and is saved with the journey.
Holds: hold a drone key, a VOX sound key, BLOOM's key, FX or a white key and the knobs play that: a voice's sound, throws (shimmer, feedback, freeze, dip), bends and pitch. SAVE in a hold keeps it.
FREEZE (ARP): the notes held keep sounding. MORPH (SELECT on HOME): walk to the next scene by hand.
SHAPE (ENV): four knobs a page for every voice; SEL twice resets a page, SYSTEM > RESET SOUND all of it.
Journeys: six presets of scenes and eight user slots; the one playing, and its loop, survive a power cut.
SLEEP: in 20 to 90 minutes it lets everything go, gently.
MIDI clock in and out, VOX on a MIDI channel (pitch bend too), USB audio, a screen reader.
The whole map of the controls is in the README.

From the betas
Journeys, user slots and settings from 0.13 to 0.17 are carried over. The betas' identity was X0X's scheme (FM-1_9...); from 1.0 Penumbra has its own (FM-1_73...).
