Hi and thanks for this question.
You're welcome to test this out with MIDI Designer Lite. Please get in touch via lite-request-3094 [at] midiDesigner.com and we'll set you up with a promo code for MD Lite.
The first three cases seem relatively straightforward, but the vibrato case is going to depend on network latency and how responsive you need the iPad to be to call it vibrato... i.e., it's an empirical thing.
Looking forward to your email. Please note: from tomorrow on we'll be mostly off-grid and unable to respond, so the earlier, the better.
Best!
Dan
