Why, exactly, did you start with those? The only sound generator there is the A-118, and all it does is produce various colors of noise. You have nothing to sequence with the iPad + A-190-4, since nothing here responds to CVs or gates. You have no output module, either, so any output you'll have will be at synth levels, even if it's just noise.
Basically, you don't have a synth there. Put those away, and take some time and STUDY what a modular synth (or really, any synth) is supposed to have: generators, modulators, modifiers and controllers, in the broadest sense. Don't buy any more modules for the time being; instead, you need to get your hands on a patchable synth ASAP and see what's supposed to be present and WHY. After some time with that, THEN go back to obtaining modules and creating a build...because, right now, you're just wasting your money pursuing a direction that won't work.
