If you want to come back to to the piano, you select it on your app, and do the same think on the irig, just that you press number 1 key instead on number 2

The small keys are not necessarily a problem, especially if you want to do stretch chords that are impossible on a standard keyboard

So far I use the irig keys with my iphone 4S, with Sample Tank, GarageBand and iGrand Piano, and works perfect with all those apps

I bought this in December 2012, and by June 2013, several of the keys are starting to 'sag' - i.e., they are lower than the other keys - feels like the key 'springs' are giving out.

Then, if you try to hit a key repeatedly fast about 10-20% of the notes will not sound

Of course, you do have to learn to play super small keys

But I would not like additional weight for more solid keys either.

It really takes a good amount of pressure to press them, especially the black keys
