FL Studio’s Piano Roll can display notes from other channels as ghost notes, including notes from overlapping Pattern Clips elsewhere in the Playlist. Seeing those notes while you edit a second part is far more useful than trying to remember what the lead just played.
The bigger problem is deciding when the second line should shut up. R&B vocals often carry busy pickups, held notes, little turns, and ad-libs, so a counter melody that sounds great over bare chords can get crowded the second a singer arrives.
Use a scratch vocal, vocal MIDI, or at least a rough lead-melody pattern before you polish the counter line. Writing the instrumental part first and hoping the singer finds space around it puts the priorities backward.
Held vocal notes need a little judgment. Sometimes they leave room for movement underneath because the singer has stopped changing pitch and rhythm; sometimes the held note is the important moment and another melody pulls attention away. Mute your counter line there once and compare.
If your second melody enters every time the vocal enters, copies its rhythm, and stops at the same places, you probably wrote a harmony part instead. A counter melody needs enough rhythmic independence to feel like its own phrase, even when both lines follow the same chords.
Pitch and timbre differences can help listeners separate simultaneous sound streams, which gives useful context to auditory stream segregation. You do not need to throw the counter melody three octaves away; give the singer and instrument enough separation to remain easy to distinguish.
Work on rhythm first. Pick one pitch that fits the harmony and tap the counter rhythm across four or eight bars, then listen for places where both lines attack together too often. Move or delete those notes before hunting for nicer pitches.
Once the rhythm has enough space, shape the notes around chord tones on the strongest moments. Passing notes can connect them, but the important arrivals should sound intentional against the harmony underneath. Keep the contour compact at first because large leaps grab attention quickly.
Register is not simply high versus low. Watch where the vocal actually spends most of the phrase. A singer might touch a high note once but live in the middle register for six bars, so placing your counter melody just outside the everyday vocal range can work better than automatically dropping it below everything.
Try making the phrase shorter than your first instinct. Four notes can establish a recognizable shape when the rhythm has character. If the line only gets interesting after another run, another pickup, and another octave jump, the first idea probably needs work.
The counter melody can also simplify when the vocal gets denser. Hold one note, repeat a small rhythmic figure, or disappear completely for the wordiest line, then return when the singer leaves space again. Silence counts as an intentional part of the phrase.
When the musical pieces are already strong, building an R&B arrangement from a loop becomes less about adding material and more about deciding where each idea belongs. Keep the counter melody on its smaller job here, answering the lead without turning into a second lead.
Do one final test with the counter instrument louder than you would actually mix it. Bad overlaps become obvious fast. Fix the notes and rhythm at that level, then return the part to a supporting volume after both melodies remain clear together.

The vocal needs rhythmic priority
Look at the lead as a rhythm before worrying about pitch. Mark the busy syllable runs, held notes, and actual rests, then place your first counter-melody notes where the vocal gives you space. A two-note answer after a lyric can do more than an eight-note run underneath it.Held vocal notes need a little judgment.

Ghost notes expose overlapping attacks
Put the vocal melody or scratch lead on its own channel, then open the counter instrument in the Piano Roll with Ghost Notes visible. FL Studio can show notes from other channels and overlapping patterns, so you can see where your new phrase sits against the lead instead of guessing from memory.Work on rhythm first.

The counter line needs deliberate rests
R&B gets a lot of mileage from call-and-response, but the response does not need to answer every line. Pick one or two places in the phrase where the instrumental reply feels memorable, then leave the other gaps empty. Repeating the same placement lets the listener recognize the idea without making it constant.Try making the phrase shorter than your first instinct.
