LTMS is a powerful browser-based DAW and music production suite with a pro-grade arranger, instrument emulator (especially for guitar), and Euclidean rhythm-based auto-composer for all instruments. Built for serious creators, from intermediates to pros.









Hi Product Hunt!
I originally intended to build LTMS for myself as no existing DAWs offered proper arranger features, especially for realistic guitar emulation. Arranging life-like acoustic music was always a pain or a compromise. What came out of that need is a full-featured music production tool for all genres that fills the gaps DAWs leave open.
I'm open to collaboration or licensing - ideally looking to sell the software to a company that can take it further. Would love your feedback and questions!
