Almost there 👍

Ah very nice MIDI support has arrived! Thanks for finally implementing that feature.

What is still missing is a way to edit/delete imported custom user amps and IRs from the user libary. The only way to delete them now is by deleting the entire app...

Please remove the popup ‘connect with audio interface’, or give this popup a small x-button to close it. Or add a preference setting to hide this popup if desired. It will just not disappear when properly loaded as an IAA in any DAW or when connected with certain audio interfaces. It also blocks the button to switch to BIAS Amp. Plus it is just plain annoying and distracting to keep this in sight at all times with no way to hide it.

Now still awaiting the Celestion IRs. Please also keep in mind the people that have already purchased these in Bias Amp. It would not be right having to pay for those a second time.

Thank you. Keep the cool updates coming and i will keep adding more stars 🌟🌟🌟🌟

Tone for days, but IAA is deprecated: need AU

I love the tone available on bias fx 2. I can really dig in and get what I hear in my head between this and bias amp. Unfortunately, I had to remove it from my live iPad rig because it crashes a lot, and loudly, with a gig-ruining full blast buzzsaw sound. With Nembrini and overloud making great sounding amps in AU format, PG really need to get an AU version out, and not charge again for it, since it should have been in v 2 from the start. Who releases a new version on a deprecated platform!? Wish I had saved my money on iOS version and stuck just with the desktop version which is stable and sounds great. I wanted to work with a platform I know and love on iOS and capitalize on the amps I've put together on desktop version for a mobile rig on my iPad. That doesn't work cuz of the crashing unfortunately. 5 stars for tone, one star for stability, features, and support. I get the feeling the PG guys are overextended.

Just needs the MIDI interface

I’ve been using FX on my iPad for years and for the last couple it’s been my go to when I’m playing at home. That said, IMHO FX2 is a big improvement. It sounds great and I really like the interface. The looper was also a nice add. This is enough of an improvement over FX that I don’t mind the $50 price tag. As at least one other reviewer mentioned, that’s about what I paid for the cheapest pedal on my board. My only complaint is, no MIDI. I like using my stomp box to switch things. This is an easy 5 once you get that patch out. Cheers
2 Aug 2020 update. Ok, you guys came through on the MIDI. Just spent a couple of hours playing all kinds of setups. Nice job on the interface, very intuitive. Upped my rating to a well deserved 5. Very nice work!

Hi there, thank you so much for the support! We are sorry about the "MIDI coming soon" issue. We want to redesign the whole MIDI structure of BIAS FX 2 Mobile and don't want to hurry the process then causing issues later on. Again, thank you.
