Melody is important.
Learnign pattern is not enough.
You maybe competent with pattern but your playing will lack something vitally imp: melody
If solo is not in some way melodic, it is really nothing more than a bunch of notes.
All the scales and patterns are just tools for you to use in your quest to improvise memorable melodies.
You have to go beyond those patterns an learn to hear melodies in your head in real time.
Then when you translate those melodies to your piano, ou are improvising melodically which is the goal of all solists.
