Startup Idea: Software to Manage Multiple Music Keyboards on One Sound Card

Startup idea to create a software program allowing musicians to simultaneously use and record from multiple music keyboards on a single sound card. The software would recognize each device as a separate instrument, eliminating the need for multiple computers and enhancing recording efficiency.

I am a musician and a problem that I have is that I can't use two music keyboards on the same sound card. This problem does not allow me to record a drum machine and a key board at the sane time. For this to happen,I have to use 2 computers at the sametime and one computer would be seen as an instrument. A program that would allow you to use two devices at the same time and recognize them as different instruments would be great. The current program that I'm using is magix home studio. I would pay for a music program that would allow this to happen. I did do a Google research.
