What FRASIL does
- Tap a key to latch a drone note or chord that rises slowly and stays, up to eight voices.
- Every drone voice layers CHOIR saws, PARTIALS additive harmonics and BREATH noise through tuned resonators, each mixed and shaped.
- PRESETS turns through 24 drone presets, ALGORITHM thins the drone with BODY, and any edit becomes your CUSTOM.
- GLINT plays four voices of icy FM bells with 22 presets, an arpeggiator and a 32-step sequencer.
- BASS holds one deep note from eight models, or runs a 16-step line of NOTE, CUT and HOLD.
- Everything flows into CLOUD, a reverb with shimmer and FREEZE, its tail from 0.4 to 60 seconds.
- Sixteen scenes keep the sound, tempo, latched drones and both sequences, and morph in over up to two minutes.
- MIDI over USB and TRS gives each track its own channel and runs the sequencers from incoming clock.
Its modes
- SOUND
- The play page, where your drone voices drift as currents of ice and K1 to K4 set CHOIR, PARTIALS, BREATH and WARMTH.
- MIXER
- Move faders and watch live meters for DRONE, BASS, GLINT and CLOUD.
- DRONE PARAMS
- Shape the whole drone with TIMBRE, SPACE, MOTION and BODY.
- DRONE SHAPE
- Set how a drone rises and fades, plus how far pressure and velocity take it.
- HARMONY
- Choose ROOT, SCALE, CHORD and VOICING so every key you tap belongs to the key.
- GENERATIVE FX
- Perform on the whole sound with SWELL, SPARKLE, BLUR and SINK.
- CLOUD
- Set the reverb's SIZE, DECAY and TONE, and hold it with FREEZE.
- GLINT SEQ
- Write and record GLINT's 32-step line, step by step or live, with accents and ties.
- BASS SEQ
- Build the bass's sixteen steps as NOTE, CUT or HOLD, each with its own length.
- SCENES
- Pick a slot, load it with PLAY, and store your sound with SAVE held and REC.
