Real jazz harmony, warm Fender-style Rhodes, clean electric bass, snappy drums, and selectable chord-locked solos.

2. Backing band
Live band breaks
Queue a clean dropout for the next bar. The complete band slams back in on beat one.
Ready. Start the backing, then choose a break.
IntroPocketLiftBreakdownSolo
Midnight Fusion · 90 BPM: Am9 for two bars, D13 for two bars, then repeat. Easy A-Dorian territory.
The band still moves through Intro, Pocket, Lift, Breakdown, and Solo, but the harmony now uses short two- or four-bar loops that repeat several times.
PERFORMANCE DIRECTOR TIMELINE

Gold is the root, green notes are strong chord tones, dark notes are the safe scale lane, and brown notes are outside colors that fit the chord.
Solo replay ghost
Watch and hear the last generated solo move across the scale neck. Slow it down to study the exact notes, bends, phrasing, and tone.
No ghost captured yet. Play a generated solo first.

6. ME-33 zero-latency setup
Connect it this way: guitar into the BOSS ME-33, then ME-33 OUTPUT L (MONO) into Focusrite Input 1 with a 1/4-inch cable. Start with the Focusrite input in LINE mode and its gain low. If the level is unusually weak, try INST with the gain still kept low. Turn on the Focusrite's Direct Monitor switch or direct-monitor mix, then listen through headphones or speakers connected to the Focusrite.
Browser monitoring is locked off because that round trip creates the delay. The app still records the ME-33 and plays the backing track normally.
Chrome calls every audio interface input a “microphone” for permission purposes. The selected device can still be your Focusrite carrying the ME-33 signal, not the laptop microphone.
