SUMMER for Mac

Release history.

What's new in each version, newest first.

SUMMER 1.5

November 10, 2026

  • A new look. A cleaner main window, and Listen shows each stem as a colored clip. Switch between Dark, Light and System at the bottom of the window.
  • Very big songs. If a song is big enough to slow down your Mac while it processes, SUMMER tells you first, so you can process it anyway or cancel.
  • Short songs in the demo. Songs shorter than 30 seconds now work in the demo.
  • Demo feedback. After trying the demo, you can tell us how it sounded and, if you like, leave an email so we can follow up.

SUMMER 1.4.1

November 7, 2026

  • Internal fixes.

SUMMER 1.4

November 5, 2026

  • Stems in subfolders. Your stems folder can now contain subfolders, so stems can stay organized the way your session exported them. If two files have the same name, SUMMER stops and tells you which.
  • Silent stems. If a stem is completely silent, SUMMER asks whether to stop or continue without it.
  • Mixes that start at a different point. A mix that starts earlier or later than its stems, such as a mastered mix with a different start, is still accepted and no longer has to be trimmed.
  • A clear warning when a stem doesn't line up. If a stem was exported from a different start than the mix, SUMMER tells you before processing, so you can export it again.
