Starting in the late 1980s, I had my own music studio setup that included Cubase on an Atari ST and an 8-track Fostex reel-to-reel recorder that was synced to Cubase via SMPTE.
These days we use software mixers, synths, sound modules, effect units and drum machines as well as musicians like yourselves. We have many years of experience recording bands and students. I have also recorded custom backing tracks for my own solo and duo acts in the past. Currently, I use Logic Pro on a Mac system and a Behringer X32 Mixer for live and multitrack recordings which gives us the ability to be mobile and flexible.
