Grid size increase/decrease button on toolbar

I want to add shortcut in toolbar for increasing and decreasing grid size 

Perfect idea 👍 Putting grid size increase/decrease on a toolbar in REAPER makes it way faster than going through menus.

Here’s how you can set it up step by step:


🎯 Step 1: Find the Actions

  1. Open the MIDI editor (piano roll).

  2. Go to Actions → Show action list (or press ?).

  3. In the Section dropdown, select MIDI Editor.

  4. Search for:

    • Grid: Increase grid size

    • Grid: Decrease grid size


🎯 Step 2: Add to Toolbar

  1. Still in the Action List, select the action (e.g. Grid: Increase grid size).

  2. Click the Add to toolbar… button at the bottom.

    • If you want it in the main MIDI editor toolbar, pick MIDI editor toolbar.

  3. Repeat for Grid: Decrease grid size.


🎯 Step 3: Customize Icons (Optional)

  • After adding, right-click the toolbar → Customize toolbar.

  • You can choose different icons (like “+” and “–”) or even text labels.


✅ Now you’ll have two buttons in your MIDI editor toolbar: Increase Grid and Decrease Grid.
You can also still assign them hotkeys if you prefer.


👉 Do you want me to also show you how to make a single toolbar button that cycles grid sizes (like your hotkey cycle, but as a button)?

Difference between MIDI editor and MIDI piano roll?

while using mouse modifiers in preference i notice there were two options midi editor and midi piano roll?  Yes 👌 you’ve spotted something important in REAPER’s Mouse Modifiers preferences: When you open Preferences → Mouse Modifiers , you’ll see contexts like: MIDI editor MIDI piano roll (and also MIDI CC lane , MIDI velocity lane , etc.) 🎹 Difference between them 1. MIDI editor (global context) Applies to anywhere inside the MIDI editor window . This includes the piano roll, CC lanes, velocity lane, ruler , etc. Example: Right-drag in empty space = marquee select. 2. MIDI piano roll (specific context) Applies only to the note area where the rectangles (notes) are drawn. Doesn’t affect CC lanes, velocity, or ruler. Example: Left-click in piano roll = draw note (but won’t affect CC lane). ✅ Why both exist MIDI editor = broad/general behaviors. MIDI piano roll = precise control just for working with notes. That way you can, f...

Difference between Note Lengths

what is the difference between set note length to 1/2, set note length to 1/2. and set note length to 1/2T?  Great question 👍 — those tiny differences in the action names are easy to miss. Here’s how they break down in REAPER’s MIDI editor: 🎼 1. Set note length to 1/2 Sets note length = half note (minim). Always straight, no dots, no triplets. Duration = 2 beats in 4/4. 🎼 2. Set note length to 1/2. (with a dot) Sets note length = dotted half note . Dotted means 1.5 × base value . So dotted 1/2 = 3 beats in 4/4. 🎼 3. Set note length to 1/2T (with a T = triplet) Sets note length = half-note triplet . Triplet means the value is divided into 3 equal parts instead of 2. So a half-note triplet = 4/3 beats in 4/4. ✅ In short : 1/2 = half note (2 beats) 1/2. = dotted half (3 beats) 1/2T = half-note triplet (~1.33 beats) 👉 Do you want me to make you a visual cheat sheet (like a small chart of note lengths with normal, dott...
