Dr. Fill – Drum Fill Generator
£12.00 £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.

v1.1.1

Add Your Own Samples, Build Your Own Kits
Let’s be honest… if you’re still using the same tired drum kit on every track, we need to talk.
The Kit Builder lets you load your own samples into Dr. Fill, whether that’s drums, vocal one-shots, bass hits, or whatever weird textures you’ve got sitting on your hard drive. Throw in something unexpected and suddenly you’re getting fills you never would’ve programmed yourself. That’s where the magic happens.
And don’t worry, you don’t need to overthink it. Dr. Fill automatically detects the sample type and even figures out the key for tonal sounds, so everything stays organised and in tune with your track. You just focus on being creative… and maybe stop using that same snare from 2016.
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.

powerful sequencer/sampler/randomizer — can be used for more than just fills! I use to make percussion grooves with the bongo/congas, low end songstarters with the toms, etc – super cool and a bargain
I LOVE THIS PLUGIN 🎵
Really cool little plugin that fits my workflow nicely. Latest version includes lots of improvements so I’m really happy with it. Especially at intro pricing.
The ability to pan the instruments beside the volume knobs.
great vet
