Use Drumville Module under Instruments. Platforms ignore the words drum fill in the style box unless the lyrics box has a [Drum Fill] or [Drum Solo] tag on its own line. Drum solos live under the red Drum Fill / Solo button (Hard Stop, Band Out, Trading Fours, 4 Bar Hard Stop, 2-Bar Kit Break, Featured Drum Solo, and more). Hard-stop solos use [Band Drop Out - Drums Only], [Drum Solo - 4 Bar Break - All Other Instruments Out], [Break], and [Band Return - Full Band Hit on Downbeat]. Regular solos use [Drums Only], [Drum Solo - 4 Bar Break], [Break], and [Band Return]. Fills use [Drum Fill - 2 Bars - Into Chorus] or [Drum Fill - 2 Bars - Into Verse]. Never put Generic Solo or a pipe character in a drum solo tag — the parser treats pipe as OR and may bring guitars back in. Pro Drummers holds signature drummer fills only. Tag sections in Lyric Lane and confirm structure first — numbering comes from your [Verse] / [Chorus] headers, not blank-line guessing. After you pick a fill or solo, we immediately ask where it goes: Beginning, End, Between Verses and Choruses, After Verse X, After Chorus X. Multi-select is allowed. Preview the tags, or tap Add Drum Fills to Lyrics. Optimize inserts them in Dual Output. Do not exclude guitars for the whole song — the fill bar already says drums only.
