1.5.0
August 28, 2026
What's New in 1.5.0 - PHLEN on the project screen sets the length a phrase gets when it does not have one of its own. Moving it stamps the old default onto phrases that already have rows, so raising it should not add silence to the end of what you have written. - EDIT with up or down doubles and halves a phrase's length. EDIT with OPT hands it back to the song default. - EDIT on a song or chain cell works on the cell in front of you. - The built-in themes have been tweaked. - The screen is drawn at a higher resolution, so widgets can carry more detail. - The MACRO oscillator's envelope is smoother. There is more to come on it. - Background playback is improved. Deeper integration with the system audio controls comes in a later release.
