In response to marcoslupo's question, feel free to turn this post into an 'app wish list'.
Obviously the hardware we already own is not going to change, we have to live with what's there. But the software that works with the hardware could be greatly expanded.
In response to iiknowathingortwo's response, i wish you would not be always so quick to shut down people on the forums here when they make what you perceive as a negative comment. i'm making these comments because i think with some additional effort the product can be made much better for more serious players like myself. So i want to provide that feedback to Line 6 by posting about it in their forum.
The amp has the capability to make some nice tones, so why artificially limit it usability for people. Especially since a lot of the limitations can be addressed in software.
Why is it unreasonable for me to use Amplifi to play music with other people? In an improvised jam situation where i need to be able to access or modify different presets on the fly while playing in real time. We are talking about a guitar amplifier, right?
I might be doing this in my living room. I might be doing this in a coffee house kind of casual performance situation. I might be playing with other people, or i might be doing something solo. I might be just playing guitar or nothing else, or i might be working with a software synthesizer on an ios or powerbook, or i might be using a looping pedal.
When you actually do this, it quickly becomes apparent that there are some usability limitations that could be addressed with additional support in software. What i tried to do with this post is explore some suggestions for options that would make Amplifi much more usable in this kind of musical situation.
Personally, i'm never going to play guitar along to a pre-recorded itunes track. Whether i'm playing with other people, or just practicing guitar by myself. So even if i'm just using the amp for guitar practice, which i think even you would agree is one of it's 'intended uses', when i'm practicing guitar i want to have access to a large range of tones i can grab and work with in real time. I need a way to organize those tones when i'm editing them. And i need a way to access them easily in real time. The existing product is lacking in both of these areas when you seriously get into using it, as i discussed above. Additional software features could improve this quit a bit. Allowing for easier organization and management of custom edited tone presets.
Recording my playing is also an essential part of my guitar practice. And an essential part of any playing i do with other musicians. Amplifi has a usb port that currently does nothing. I will feel a lot better about my purchase when that feature actually starts working. I would expect the ability to record the effected guitar output back into my ipad, or into DAW software on a mac computer.
