I think in today's world the easiest way to record practice sessions would be to use an Apple smartphone. Get a microphone or music stand, jury rig an adapter so you can mount the smartphone to the stand, place the smartphone stand in a position so it can reasonably receive the sound everyone creates.

Life is good, especially if you have an Apple smartphone. If you don't want to use the built in microphone, several companies make audio interfaces that connect to an Apple smartphone either through the headphone jack, lightning port or through the optional camera interface. Those interfaces let you connect an external microphone, provide a stereo line in or direct input (DI) port. One manufacturer that comes to mind is +++ 1K Multimedia +++. 1K Multimedia has a wide selection of products for interfacing to an Apple smartphone.

Android users are not as lucky since Android did not support audio until version 5.
