You can probably pick up a used Timeline for that At least a timefactor. Im not really a fan of the boss modern delays, but it will be cool if the vintage setting sounds like on their old 12bit boxes.
I Find roland does something weird with the gain stage on ALL their stuff (maybe to make it “Loud” in the shops)… I had the RE20 and the distortion from the gain was unusable for me. (interface was great though). The System 1 is a nice emulation of their old synths but even on the sotware versions if you put the volume more than half way they start to saturate (same as the hardware). it’s a really strange was to go about things lowering the headroom like that.
I succumbed to an Eventide H9. Which being a guitar pedal primarily (although it has synth and bass input options) made me think “hmm, I’ll learn guitar” and so I am.
I almost got an h9, but the whole lack of knob per function and having to use an ios device to manage stuff kinda turned me off. For the price of an h9 max, id rather have the suite of a timefactor, pitch and mod.
There’s an expression pedal port which is effectively a CV input (just don’t go too high with the volts).
But it is ultimately a guitar pedal, so it makes little sense to have a load of knobs on the front. Given this fact they have been quite flexible in allowing MIDI control, bluetooth etc.
The FX algorithms are very high end stuff, the sort of things only stadium bands would have had access to years ago. A studio rackmount of theirs will cost £3000+
