-  **Play**: plays from cursor position.
-  **Stop**: stops all playback.
-  **Play from the beginning of this pattern**: plays from the start of current pattern.
-  **Repeat from the beginning of this pattern**: repeats current pattern from its start.
-  **Step one row**: plays only the row at cursor position and moves down one.
-  **Edit**: toggles edit mode. when turned off, you won't be able to enter notes.
-  **Metronome**: toggles the metronome, which only works during playback.
-  **Repeat pattern**: toggles pattern repeat. during playback while this is on, the current pattern will play over and over instead of following the order list.
- **Poly**: turns on polyphony for previewing notes. toggles to **Mono** for monophony (one note at a time only).
- **Octave**: sets current input octave.
- **Step**: sets edit step. if this is 1, entering a note or effect will move to the next row. if this is a larger number, rows will be skipped. if this is 0, the cursor will stay in place.
- if clicked, Step becomes **Coarse**, which sets the number of rows moved with `PgUp`, `PgDn`, and related movement shortcuts. clicking again will revert it to Step.
