It’d be helpful to tell us what you’re using as input for any targeted suggestions. Much easier to narrow down this broad topic to a guitar, synth, or some other source inputs (flute?). Also, are you using an expression pedal or aux switches with the H90?
For generalities, have a look at the H90 Patchstorage entries. There’s a little bit of everything represented there, and many hundreds of Programs & Program Lists to choose from. The patch descriptions should guide you in the right directions.
