Live mixer & stage plot
Decibel faders, voice mutes, and per-instrument stereo panning. Mix & EQ Studio adds draggable EQ dots, scroll bandwidth, rotary knobs, a level-matched Linear preset with slope shortcuts (default −5/3), DJ filter, echo, stutter and sweep pads, plus separate bass/drum Instrument FX racks for drive, wah, chorus, phaser and delay, with named presets, one-click reset and compact bypassed racks. A desktop toolbar puts every practice tool at the left edge, with descriptive tooltips and distinct piano-key and EQ icons.

12 Feels & Style Lab
Acoustic jazz kit, Latin percussion, and a groovebox synth. Soul Waltz brings a modern funk groove to 3/4, and Soul 6/8 plays the neo-soul / Afro 6/8 pocket felt in two. Samba brings a real batucada — pandeiro, tamborim, ganzá, agogô and cuíca over a kick surdo — with the samba swingue: the third and fourth sixteenths of every beat land early, at every tempo, with a Swingue knob to set how deep. Tresillo and Bolero modern layer kit drums with hand percussion; Bolero modern brings the standard kit forward, accenting the & of 2 with bass, kick and snare. Build and audition custom accompaniment styles in the lab; Microrhythm combines its plots, supports draggable uncertainty, auto-applies edits, offers a small-kit Minimal groove with coordinated bass and comping, includes an experimental Bossa Nova copy, adds a Traditional base that plays African and Réunion patterns on an approximation of their own ensembles, filters timing patterns for Swing/Samba/Bossa compatibility, places a vertical λ slider beside the first diagram, simulates 1–128 bars (default 16), and places affected players at the bottom, highlights the exact affected players, gives Samba the same whole-band timing scope as Swingue, includes measured Waaju and other four-onset studies, and extrapolates λ beyond A/B on an extended shaded diagram. When the chart and stage scroll out of view, a floating Chord changes panel keeps the stage’s rolling playback chords visible, with Play/Pause and tempo; long charts collapse sections to their first line except the one playing.

Knowledge base & embeds
In-app wiki covering rhythm style structures, plus integrated Spotify and YouTube reference embeds for context. Song Info → Play Video adds supported speed controls with YouTube’s pitch correction, grouped playback controls and A/B phrase loops with an optional local-recording waveform popup (zoom, video offset and click-to-place markers), a draggable trim timeline, editable hundredth-second timestamps and fine nudge controls, saved local markers and a manual BPM calculator using taps or counted A/B spans, with playback-speed correction. Soul 6/8 Brushes combines a bass energy ladder from alternate-bar roots to phrases with late pickups and pauses, soft snare rolls and light shaker motion. Solo Transcription separates piano locally before detecting both hands across the full keyboard, with up to three-minute passages, an isolated piano player and WAV download, Both hands or Melody only staff/PDF views, adjustable downbeat alignment, readable tied notation, direct editing with MuseScore-style keyboard shortcuts, swing notation, requantize, split/join/tie and copy-paste, slowed-down selection loops, MusicXML export, undo/redo, synchronized audition and private study files. Online piano separation requires the local helper. Separate agent-assisted reference groove development uses a local audible review before a new style is authored; see the manual.
Solo Transcription remembers original recordings privately on this device for playback after reopening, and Detect follows the beat in the original recording so barlines and chords keep up with a band that speeds up or slows down. Per-bar Half/Normal/Double corrections fit compressed or held measures in the recording without changing the tune chart.
