If you are sure you want to do it (see other posts!) then I would agree with others that getting your foot in the door with a webdev related role could be a good way to get into it, especially at a smaller studio with less defined roles and more flexibility for people to help out on other bits.
Personally I’d always been interested in music software development but my career was in webdev. I took a job at a music tech startup doing Node/React work, but was able to make a prototype using React Native to build the UI for music apps during the regular hack days we had there, which led to me teaching myself C++ and leading development of a new music app for them. I actually am not working in the music world any more but still do some for fun on the side, and found knowing both C++ and JS has opened up some really interesting job opportunities so it worked out well for me!
