As mentioned, I tried the I Dock from Alesis today (updated to the latest Ipad system), I am not in love with Apple and the Ipad, which is castrated computer.
Shitty export function, which is a shame, no file system............
Garage band is quite pretty, but there would be much more possible.
The mic preamp on the alesis is a toy, sounds like garbage, very week with a Gefell Um70s, IMHO useless, use the implemented Ipad mic to make short sketches, which is certainly possible and cool.
The worst part (as I feared) the latency.....tried to trigger the drum sounds inside garage band with a Roland TD12, it´s (Alesis) laggyness is not usable for performing, the sounds is quite nice, reduced playability could not hope for more.....but the playing performance is probably above 15ms
(you can get 2,5-3ms with RME Soundcards on Mac and Pc, Axe FX is around 2ms) which is not tight enough for serious music making and the use of plugins in real time.
If the alesis is the culprit or macs Ipad sound implementation, I do not know.....
A friend bought the new RME UCX yesterday (for e-drumming and recording his band with a mac mini), we will see, if it will make a better job latency wise, they implemented also rare Ipad compability.
Will try guitar modelling playing tommorrow, doubt it will be cool...
Will try the small Ipad apogee interface for guitar playing next week, my buddy indicated that he feels latency though
I used a second generation Ipad.
