Hi Chasbee,

Sounds like a very interesting option to explore, be it with lots of caveats. But if you already have an ipad it might be well worth going down this track.
I would like to add that I bought the Behringer BCF secondhand for 75 euros and that it does not need any software etc. but handles admirably and with real ( and substantial sliders) and knobs. To the best of my knowledge two folks that I know have one on order so I will wait and ask them for their reports later on. Personally I am still puzzled by the seemingly lack of interest in this contraption. For all those in the USA , zzzsounds have them in stock with a 30 day trial period !!!

regards
John
