using flex sensors in a glove

I'm making a musical glove with several flex sensors and a force sensor. I have the sensors wired to an arduino uno and then I'm reading serial data into PD for processing and MIDI conversion.

admittedly, I'm a new to arduino and need help... I have one sensor sending data at this point, and all works great. I'm about to connect the rest of the sensors but I'm at a loss as to how I keep track of all this data. Won't it be a garbled mess of values? what would be a good way to organize and send?

Won’t it be a garbled mess of values?

Not if you code it right.

what would be a good way to organize and send?

With some start and end markers:
<val1, val2, val3, val4> <val1, val2, val3, val4>
