Voicings are where the ear runs out first
A rootless left hand under a fast right-hand line is a lot to catch at tempo. Slow the chorus to 60% and both hands become legible. Loop the A section and drill it; save the bridge as a note and come back to it all week. The pitch heat map is at its best here: select the chord you cannot place and see which pitches carry it, then let your ear pick the voicing out of the candidates.
A detail worth knowing: the two-octave reference keyboard doubles as a silent check for a note you think you hear. Everything else SlowBird does (the searchable library, per-track memory, the five-band EQ) is described on the main page, and the core tools in depth under slow down, looping and notes.
And as the collection grows, the notes viewer keeps it in reach: every note in your library on one canvas, grouped by tag, soloist or track. Search “#voicings” and every voicing you have tagged lights up; click one and it plays.
