There are plenty of free (and some open-source, cross-platform) DAW stations like LMMS that you can download and configure to play MIDI input. The easiest method is to play directly from the browser through a web app such as midi.city, the Online Sequencer and many others to discover online. In principle, web apps such as midi.city will readily detect your midi instrument (the micro:bit in this case) and you are ready to play after giving the browser permissions to access your device (which you will be asked to do).
