Have to settle 4 this on iPhone instead of bias fx

Before Bias amp & FX, this was the top dog, now its running somewhat of a distant 3rd, may 4th behind AmpliTube 4, and to be honest, I feel like I'm settling for this when I'm using my iPhone. I'd much rather have bias fx on my iPhone as I use it as my go to for my iPad , and I don't understand why they can bring bias amps but not fx to the iPhone. Anyway this app, while it lacks the possibilities of bias fx, does have its own offerings, but one of them, the 8track, is terrible and a waste of money, as it lacks so many basic features it should have.

Missing important features

There is a lot to like about this app. Unfortunately until they fix the GUI on iPhone 6 Plus it stops short of a win. They need to add better control of the rehearse loop. I contacted support and they say there's a blue dot that shows up when you turn it on. However you can't see it on the 6 Plus. So you end up hitting the loop start "A" button or the loop end "B" button. For most people who might want to use this to drill licks, the tight space around the loop control buttons means you'll end up hitting them repeatedly when you try and enable the loop. This will make practicing your parts a lot more frustrating.

They could make the potentiometers much smaller to gain a little room on the interface for the loop controls, or even use sliders instead. Sliders would actually be better. I would think it would be obvious that the more necessary controls are the looping points and the loop on/off button. There's also no way to set the loop's starting and end point accurately. So you end up with the loop starting or ending in the middle of a measure. If they did some work on just the practice loop section this app would be perfect because you always have your phone with you when you are at a gig and if you carry the interface too you can work on tunes backstage before you go on. It would sure be a lot more convenient than a laptop.

The multi-track recorder would be nice if it would sync with the drums they provide like most DAWs do. This one doesn't.

They have a lot of pedals you can add and they are reasonably priced. If the Graphic interface were better I'd likely buy more pedals because I would really want to use it. Sad really. It's almost there but missed the mark. If you're not a professional player than you'll probably dig it.
