Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

PPG WaveGenerator and Phonem - parallax effect in the Spectrum Editors and other controls
When I use the Spectrum Editors in these two PPG apps, both seem to have a problem that it’s nearly impossible to change them precisely. That is you’re trying to select one, but end up adjusting the adjacent one instead. In WaveGenerator only if you zoom in to the maximum you can tap them precisely, but then you don’t see much context. In Phonem you can’t zoom in, and selecting the rightmost partial is nearly impossible even with a Pencil. In WaveGenerator on the Wave page, all 3 grids are affected can’t adjust anything and always select wrong things. In Arptor page parallax is completely off. The matrix in Phonem seems to be very precise though. Absolutely love the potential of these apps but can’t use them at all 
Could someone please test this? I wonder if this is an iOS bug and is something new, or maybe even exclusive to my device (iPad pro 10.5”)

(Hope you don’t mind tagging you guys, was reading your comments on these apps in other threads)
Thanks!
