I own a PS3 ....and i prefer it to the PS5 .... it has a few enhancement but the PS3 has its mojo for me.
Maybe its the out of production Harmonist is what want to look at ...hard to find and difficult to use...i almost went bongkaz playin with it 8O
well it's (obviously) a completely digital pedal, so the sound that comes out is kind of "cold" or "stiff"..not to knock on digital stuff though, my favorite delay is the echo park
basically, the ps-5-generated sounds don't sound exactly like your guitar does at a higher octave. with my usage (i put it in a true bypass loop after a z.vex fuzz factory, z.vex super duper, and mi audio crunch box), i've found that the generated octave/5th/whatever sounds kind of synthy..which works great for me as i'm the only guitarist in a 3-piece and it really lends a lot of depth to my guitar sound. i'm pretty sure that my putting it after my drive chain is responsible for the synthy-ness because it sounds pretty accurate when it's clean.
