In reaper piano roll i draw some notes and want to make make note one octave above those chose same chords so for that i have to copy them and paste then move them so it's a long process i want shortcut to copy and paste one ocate or on whichever pitch i want to copy Got it 👍 You don’t need to do all that manual copy–paste–move in REAPER. The MIDI Editor has shortcuts for this. Here’s how you can quickly copy chords one octave up (or any interval you want): 1. Duplicate notes one octave higher Select the notes you want. Press Ctrl + ↑ → moves notes 1 semitone up . Press Shift + Ctrl + ↑ → moves notes 1 octave up (12 semitones). Same with ↓ for down. 👉 If you also want to keep the original (not just move them): Hold Ctrl (Windows) / Cmd (Mac) while dragging with the mouse → it copies notes. Then press the octave shortcut (Shift + Ctrl + ↑). 2. Even faster workflow (custom action) If you want a single shortcut to copy selected notes and place them one octa...

someone told me if i take chords of a song from google and draw on piano roll in daw i can learn how to place chords and which chord sound better and you can play your favorite songs but here the problem is i find chords on google and place them on midi but they are not sounding good. because there is not written in what grid length or note length i have to take  You’ve figured out exactly the missing piece! ✅ When you search for chords of a song on Google, you usually only get the chord names (like C – G – Am – F ) but not how long each chord lasts (the rhythm, timing, and progression feel). That’s why when you just drop them into the piano roll, it sounds wrong or boring—it’s missing the rhythm and structure . Here’s how to fix it step by step: 1. Understand chord symbols If you see something like: C G Am F It means those are the chords, but the duration of each chord depends on the song’s rhythm (bars/beats). 2. Find the timing (grid length) Most pop ...

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 Open the MIDI editor (piano roll). Go to Actions → Show action list (or press ? ). In the Section dropdown, select MIDI Editor . Search for: Grid: Increase grid size Grid: Decrease grid size 🎯 Step 2: Add to Toolbar Still in the Action List, select the action (e.g. Grid: Increase grid size ). Click the Add to toolbar… button at the bottom. If you want it in the main MIDI editor toolbar , pick MIDI editor toolbar . 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 ...

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...

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...

is there any condition require for shortcut select all notes in one measure in midi editor  Yes 🎯 — in REAPER the MIDI editor doesn’t automatically know what you mean by “one measure” unless you run the right action . 🔑 The conditions Time selection or edit cursor position matters REAPER has actions like: Edit: Select all notes in time selection Edit: Select all notes in measure under edit cursor So, to “select all notes in one measure,” you usually need either: A time selection covering that measure, or Place the edit cursor inside the measure you want. Correct Action Section In Action List , make sure the Section = MIDI Editor . The shortcut won’t work if you assign it in the “Main” section (outside MIDI). Snap/Grid doesn’t matter You don’t need snapping on — the command looks at measure boundaries, not grid divisions. ⚡ Example workflow Place the edit cursor inside bar 5 → run Select all notes in measure under edit cur...
