Live interactive sampler with the audience

Hello!

I'm quite new to this software and fell in love with it at first launch, and now I intend to create something more interactive for a project next year.

I play the piano and mostly performing classical music. I visualize this project where I'm playing a piece and/or several pieces and during the time I play the audience have the opportunity to record or trigger a recording of already prepared mics on the piano. The types of samples I would be looking for would be limited to a certain size/length because of the area of use I'm looking to utilize the samples for. This arrangement would need some kind of Bluetooth or wireless connection to max/msp for triggering a record. And it would also need to be sustainable for up to 50 people recording samples.

So my first question; is this possible with Max 9? Are there any plugins and object where you can interact with a patch from your phone through eg. a website?

I would then use the samples in a sort of granular synth by using the sounds from the already played piece (maybe from prerecording of the next piece) and then creating a sort of atmosphere which goes into the next piece where this procedure would be repeated.

I'm glad for any answers in helping me with this as a relatively new and green user for this software. Any sort of collaborations are deeply welcome!

Thank you!
