Disappointed but ill give it 4 stars

I love the app I have it on my iPad and use it daily just to mess around and jam with some of the music on my iPhone, but one thing I’ve noticed, the description on the app says I can record with this version of the app, and I can’t for the life of me find away to record anything. I won’t pay for the app unless I can record. It’s a major issue. Also a little side note, I hope if there is a way to record it’s more than just a looper.

Adding to my rating:

A buddy of mine bought me the elite bundle for Xmas, I love all the content but definitely need more than a looper to record anything so now I need a computer so I can figure out how to record my ideas. Anyway awesome app can’t wait to see what future updates bring thank you for an awesome app.

Versatile and convenient

I love this app,i use it everyday,it is well worth the money,i used the free trial and was so amazed with the sound and all the effects that i had to purchase the elite pakage(again,it is well worth it IMO) also with the bias amp app brings it to a whole other level of creativity and sound,i can bring my ipad,irig hd2 ,guitar and a bluetooth/portable speaker and litteraly jam heavy face smashing tones anywhere “is that kerry king i hear outside”? Nope just me at the park on the bias fx2 app ..i love how i can jam with out needing an amp/pedals or electrical outlets(as long as ipad and speaker are charged of course) but its truly a remarkable app and only thing id do different is id of gotten it earlier,im not a company rep nor do i get anything for this review im a regular dude who loves to whale on his axe and with 20 yrs exp and at 37 yrs old ,this app saves me time money energy and space, glad i can worry only about “headphones or speaker?” TLDR: GET THIS APP!

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.
