Music Studio is a Windows-based SID music creator software. For an accurate C64 sound, it utilises the newest RESID-FP emulation available, both old (6581) and new (8580) SID chips. MS2 is capable of creating 1x speed tunes and many SID chip parameters can be edited directly using the various commands. Classic and new C64 sounds can be created with envelope parameters that can be set up in few simple steps.
While I’m sure purists will greatly prefer real hardware, the cold and harsh truth is that the number of real, authentic Commodore 64 models is slowly running out, and there’s only so many Adrian Blacks in the world capable of repairing the few that can actually be repaired. Emulation – even for specific features of the C64 such as its sound capabilities – will make the C64 immortal.
Nice, but win only… Goat Tracker 2 is multi-platform (https://sourceforge.net/projects/goattracker2/), its currently active fork GT Ultra is also multi-platform (https://github.com/jpage8580/GTUltra), while SID-Wizard runs on Linux, Windows and Commodore 64 (https://csdb.dk/release/?id=221555).
