Dr. Fill – Drum Fill Generator
£17.50 £35.00
Dr. Fill is a drum fill generator built to help you create dynamic transitions and happy accidents in seconds. You know the moment. Your track is going strong, it needs a fill, and suddenly you’re stuck either overthinking it or throwing in something that barely works. Dr. Fill fixes that. One click, and you’ve got a fill that actually sounds like it belongs.
Generate, tweak, and drag fills straight into your DAW without breaking your flow. Shape the groove with density, swing, and humanize, or keep things moving by randomizing until something clicks. With the new Pattern Lock, you can hold onto a rhythm you like while exploring different sounds and variations around it, making it easier to refine ideas instead of starting from scratch every time.
The new Kit Builder lets you go beyond stock sounds and build your own kits using anything from classic drums to vocal chops, bass hits, or textures. Dr. Fill automatically detects sample type and even handles key detection for tonal material, so everything stays organised and in tune with your track. It also now supports a wider range of sounds including kicks, bongos, congas, and additional percussion, giving you more flexibility when shaping fills.
You can now export MIDI or trigger Dr. Fill directly with MIDI input, making it easier to integrate into your workflow however you like. Whether you want fast inspiration or precise control, Dr. Fill gives you both. It’s quick, flexible, and designed to make sure your transitions sound intentional instead of like something you rushed at the last minute.

Add Your Own Sounds
Still using the same tired drum fills on every track?
The Kit Builder lets you load your own samples into Dr. Fill, from drums and vocal one-shots to bass hits and strange textures buried on your hard drive, then turns them into fresh, playable kits in seconds. It automatically detects the sample type and even finds the key for tonal sounds, so everything stays organized and in tune with your track. Just drop something in and start experimenting, because the unexpected fills are often where the magic happens.
Generate Drum Fills Instantly
Programming drum fills manually often starts with confidence and ends with something you quietly delete five minutes later.
Instead of going through that whole process again, just click Dr. Fill. One click generates a fresh fill you can audition instantly, giving you something usable before things spiral any further.
Built for Creative Exploration
Sometimes the best ideas come from trying something you wouldn’t normally program yourself.
Randomize fills, tweak parameters, and explore different rhythmic possibilities without getting stuck fixing the same four bars over and over.
Stay In Key
Your drum fill doesn’t need to accidentally invent a new scale.
Just select the key of your track and Dr. Fill will tune the toms and snares so the fill fits musically. Turns out transitions sound better when they’re actually in key.
Flexible Drum Variation and Groove
Not every fill needs to sound like it was programmed in a moment of panic.
Use Density, Swing, and Humanize to control how busy, loose, or natural the groove feels. With a few small adjustments, your fill might even sound like it was planned.
Loop Slicer
Create drum fills from drum loops.
Dr. Fill chops your loops up into single samples and allows you to generate fills from them in a few clicks.

Sorry not use it now .but the plugin are handy to have.new update .comming.gets only better.
Absolutely great! Would love to get different preset sets and a manual assignment for my own drum types (auto is not working so good). But overall its a tool I will use frequently
Hey Steve, you can manually assign your samples to different drum buckets, you just go to the kit editor and you can click (or shift + click for multiple) and drag from one bucket to another. We have also just updated to 2.0.0 which added new drum kits!
The patterns it generates are hard to use in a song and don’t follow a natural drumming pattern . Bit too random
Hey! We have improved the drummer algorithm in the latest update (2.0.0) so they should feel more musical. Please update and let us know what you think!
plugin tremendo para hacer breaks o usarlos de manera creativa
