Export your chiptune as WAV or MIDI
Export a mix as a WAV, or the song as a MIDI file to carry into whatever studio you use. Both are in the File menu.

WAV
A 16 bit stereo file at 44.1 kHz, ready to upload, master or drop into a video.
MIDI
A multitrack MIDI file with one track per channel, so each voice lands on its own track in your DAW. MIDI carries the notes; effects with no MIDI equivalent are left out.
Mix first
The Song tab has the mixer, tempo from 40 to 295 BPM and tuning, so the export sounds the way you want.
Questions
Will my arpeggios come through in MIDI?
MIDI carries the notes. Effects with no MIDI equivalent, and pitch bends, are not rebuilt. Export a WAV to keep the exact sound.
