Guitar Chords/Notes Getting Cutoff/Muted Problems?

Well I tried to search for similar issues and couldnt find one, so please forgive me if this has been discussed already.

So I just recently picked up an iPad1 and the garage band app, which I have to say is pretty darn cool for an app. I am a long time Logic user, and have been playing around with this app a bit and am noticing a really big cutoff problem. If I try to strum chords manually (to hit certain parts, rather than a straight strum down every time like the button does), it sounds fine. But when I play back the recording it doesnt hold the chord. It acts as if I muted the chord so whenever i change the pattern it cuts off other notes. I also notice it does this most of the time when I pluck out individual notes in chord mode as well. I have tried some variety in the way i record it such as holding down the string longer, or keeping my finger on it, making sure I am not hitting the back part which I noticed purposely gives a muted sound, and have made sure im not accidentally pulling off a string pre-maturely.

The strange things are that when you play it sounds like its keeping the sound, and the midi view even looks like the note lengths are being held, and dont display a small picks.

Is it possibly just that iPad1 cant handle the processing? Anyone happen to know if exported to a desktop version it will work properly. Anyone else notice this same issue (Id assume plenty have)?

Any help would be great, I am just very curious about this as I really think its a great little App for something like the iPad.

Thanks!
