Question for you spark users.. I would REALLY like to be able to do one thing with it.. record me playing along with a song from Spotify INTO my iPhone. I can of course stick my phone next to the speaker but it doesn't sound too good (especially when compared to headphones). I have a usb to lightning cable that has allowed me to record just the guitar. I have never used garage band app (only seems to record 8 bars- I will need to explore more). I do have two iPhones (a newer SE and an older SE so one could play and one could record). When I play the Spotify music it won't come out the usb to lighting cable to be able to be recorded- I only record my playing. Sorry if the above in confusing. I just think it would be cool to record me playing along OR add guitar to song that never had them. Any tips a much appreciated. I am not a professional so I don’t want to buy tons more equipment. Thanks in advance. I can imagine that it is a copyright issue etc.. just trying to have some fun personal mementos.
