Spectrum has a lot of granular and spectral functionality as do Alexander Zolotov’s apps (e.g.
Audulus 3 tutorial plus#
The Wotja app has lots of the functionality you’re looking for plus JavaScript.

There is RunloopSound for learning and creating Csound. If you haven’t already checked it out, you might want to look into MobMuPlat, PdParty, Holonist.ist or zMors modular as they all have some Pd support. I hope it's still receiving active development. But if you plan to work inside the modular environment alone, Zmors is unique with it's IAA and AUv3 hosting ability. It doesn't always work a expected, especially when splitting cv and gate from midi modules. It doesn't have a great deal of modules - but it can host Auv3's and modulate exposed parameters. Finding them in modular environments are going to be even more difficult. Spectral is quite niche, Izotope and apeSoft specialize with it, but even on desktop there's not a great deal of spectral effects. There may be some granular modules - I don't know if it's got Clouds yet. Got lot's of real world modules like the Mutable Instruments catalogue.

MiRack is closest to a hardware euroack workflow. Handles polyphony better than any other IOS modular. Granular is on the roadmap, but not yet available. Plenty of maths, several sampler modules. It's fresh out so it's getting a lot of attention, and great roadmap for updates and improvements. Drambo is hands down the easiest/fastest modular workflow on IOS.
