I make music, and every session ends the same way. I bounce the mix to a file, close the DAW, and listen to it the way a stranger would, with a notebook open, writing down what to fix next time. That process used to take three apps: one to play the track, one to read how loud it is, one to write in. Every switch between them broke my concentration.

So I set out to build the one window I kept wishing for: the whole pass in one place. I wanted the track playing, its loudness drawn across the screen, and my notes pinned to the moments they're about. The rule I held to was simple: nothing on the screen should distract me from listening.

This is the window. Everything from the old three-app routine now lives in one screen. The track plays. A line shows how loud it is from start to finish. And when I hear something worth fixing, I write it down right there, on the track itself.

Everything happens where you are looking. Click anywhere on the plot and playback jumps there. Press Cmd+N and a note opens at the exact moment under the pointer, ready to type. Press Return and it settles onto the track as a dot. If it landed a beat early, drag it. A thought is written down in the time it takes to have it.

Two sheets live under the window, and each is one key away. T lifts the tracks: every bounce from the session, in the order it arrived, with the playing one in orange. N lifts the notes as a list, each with the moment it belongs to, and a box to check when it's fixed. You don't have to open the list to finish a note, either. Pull its dot off the track and two targets appear beneath it. Drop it on the check and it's done.
