MDrummer is a percussive instrument engine. Advanced users can use the rich set of capabilities to enjoy the power of sound and rhythm systems of the virtual drummer. Beginners can use MDrummer simply to create great drum-tracks in almost no time.

MDrummer offers VST plugin and standalone versions. MDrummer Small is a free MDrummer edition which contains everything you need - standalone application and VST plugin.

Features / Specs / Info:

  • Large library included:
    • 4.5GB in 500+ multisamples (Gretsch Birch and Sonor S-Class drumsets played with sticks, mallets, floppy, brushes and hands).
    • 150+ drumsets.
    • 750+ drumset components to generate your own unique drumsets.
    • 200+ rhythms.
    • 100+ base-rhythms useful to generate your own unique rhythms.
    • 12,000+ loops (most of them recorded) useful to generate your own unique rhythms.
    • Sub-sample libraries, samples, effect configurations, layers and more.
  • Universal Sound System lets you tweak the sound providing advanced tools - plugin based sound generators (several samplers and synthesizers) and effects (compressor, equalizers, phaser, vibrato, tremolo, etc.), unlimited number of drums, velocity layers and effects.
  • Drumset Generator and Merger can be used to generate almost unlimited number of original drumsets in a few clicks.
  • Rhythm System (MRS) gives you power to create rhythm tracks in minutes without limiting your creativity. Any style, any signature, any percussion instrument, strictly general MIDI compatible.
  • Plays groove, automatically puts fills and just works like a real drummer. And now you can jam with him. Give him order to play and he will know what to do. You can practice or jam with him, build rhythm tracks for your songs or even use him instead of a real drummer. Connect your MIDI device, enable jamming mode and just play and MDrummer will try his best to play with you.
  • Rhythm Generator creates the entire rhythm containing groove (alterations with different complexity levels) and hundreds of fills, intros and outros from just one groove base loop. This way you can always create a perfect rhythm for your song. You create a groove base loop, which defines character of your rhythm track. Then you select some predefined settings and click a process button.
  • Simple user interface. All controls are made so that you can configure everything as smoothly and quickly as possible. No confusing knobs and complicated layouts. You always see the exact value you are editing, you can always ask for help by pressing F1 or clicking one of the "?" buttons.
  • Save your own resources and organize them in folders for quick access in any project.

Updates and packages are free for life - MDrummer downloads and installs updates and additional resources (samples, subsample libraries, rhythms, grooves, etc.) for free.

Mdrummer is great when it works. I have Bitwig 5.1 and I cannot get it to sync properly for the life of me. Theres times when it gets hung up...I'd press the play button, the time line moves but it generates no sound. Sometimes the time line freezes randomly and it stops playing music. Its buggy. In addition, it does not work with Bitwig. Bitwig would play the MIDI note corresponding to the correct loop and there is a 1 bar delay for it to start playing...and again, sometimes it does nothing.

Also there is no easy, simple way to direct Mdrummer to custom file paths, which is ashamed since this is not a sample management software, the least they could do is give you greater flexibility with custom sample paths. You would think in the last 10 years, it would work flawlessly.

Why am I still giving it 4 stars? Because there is nothing like it on the market. Its a powerhouse hands down. If you truly know the software, you do anything you want. The ability to easily layer drums with other samples and drum synths is unheard of. The main thing that I love about the software is that it allows you to build entire compositions from simple loops, which I dont see anyone else doing. Many drum softwares now are basically loop based and it ends there...after 4-8 bars. Mdrummer gives you the ability to structure your drum loops into greater musical ideas while retaining YOUR style. I dont see this out now.

For now, Im using a sequencers while driving my custom drumkits in Mdrummer...until they can get this DAW Sync thing right.

Well, I have to say that Mdrummer is the best virtual drum machine I have ever used, and I have used quite a few, Mdrummer is versatile, reliable, stable, you can do anything that requires percussion, the features in the mixer where you can use all the Melda plugins, from el, saturation, compression, effects is fantastic. I am more than satisfied with Mdrummer.

Because this isn't a "virtual drummer" VST, but instead an extremely intricate MIDI drum generator and drum VST, I decided to give it a 3/5 - it falls somewhere between Air Strike 2 and Rayzoon Jamstix 4 - both of which I prefer. This should rather be called a "virtual drum [machine/MIDI] programmer" drum VST, or a "drum VST and MIDI drum generator" but it isn't a "live A.I." with a brain like Jamstix, which is the only virtual drum/mer VST. If they called it what it was, I would give it a 4 or 5/5. However, it isn't remotely close to what a virtual drummer is so it lost 2 stars for not being forward. In fact, as much as I think this is better than Strike 2 by Air, I'd rather recommend Strike 2 because it is more of a virtual drummer VST than this is....however, both are inferior by leaps and bounds to Rayzoon.

MDrummer by MeldaProduction claims to be the "ultimate drum machine and virtual drummer." Well, many companies make many claims, so I approached this plugin with skepticism. After three days of intensive exploration, tweaking, and noodling, I found myself mostly agreeing — this is an excellent drum/rhythm plugin. MDrummer really does seem to have endless possibilities. I was able to create any kind of sound I could think of with the sound generator via synthesis or sample (acoustic, electronic, percussive, scratching, etc.). I could then pile up layer upon layer with effects, build a zillion drum-sets, and get it moving and shaking with any genre rhythm in any time signature.

The rhythm generator was the main reason I gave it a go. I'm not a drummer, but I want sound like one. I created a simple beat that fit my track, and then generated variations, intros and fills. It's an amazing feature. If MDrummer was scaled down to only the rhythm generator, I would still consider it a must have and a good value. But it has many other things going for it. . .

• Easy installation, but takes time due to big library
• Simple and resizable interface (not the most attractive GUI, but utilitarian and efficient)
• Gigs of great sounding drumsets and loops
• Several sound generators for samples and synthesis
• Integrated Sequencer with humanization and shuffling
• Tempo adjustments and rhythm changes throughout a song
• In vivo value changes while tweaking
• World-class MeldaProduction effects (EQ, compressors, distortions, phaser, vibrato, tremolo, etc.)
• Jamming mode
• MIDI file drag & drop.

And my two favorite features besides the rhythm generator are. . .

• Lots of support (help system, tutorials, responsive developers)
• Free lifetime updates.

MDrummer has a strong, loyal user following. So, I'm confused! Why isn't everyone using this thing? Well, the interface is not for everyone, but the sound and flexibility is there. I highly recommend MDrummer to any e-musician, sound designer, songwriter, or producer who is looking for a primary rhythm box with endless possibilities or a secondary source to help generate unique rhythms that can trigger other plugins. Download the demo and see if it suits your sensibilities and workflow. I give MDrummer three thumbs up and my virtual hat is off to MP for developing such a wonderful rhythm workstation. Thank you.

Recently I've been feeling dissatisfied with Razoon's Jamstix and I went out a hunting for a replacement. I came across a post suggesting mDrummer and I figured I'd give it a try. The free version was really promising so I downloaded the demo and had some fun with it. I liked it so much I went for the full version. Note, I had a small problem with the demo and the developer had a new version that fixed the bug up within a few hours. That's service!

Installation: This thing comes with a big library. Not giant, but big. In the neighborhood of 4 gig so it's best to start the download before you go to bed and you'll have it all ready to install in the morning. The installer had a setup file and a fix.exe file in case something bad happened with the big download. All was OK so I didn't have to use it. Installation was a breeze and withing a few minutes I had it up and running in Live 7. First thing I did was go to the tutorials. I love that there are tutorials, but mDrummer, even if you don't have the best voice for recording, please don't use the annoying computer voice. It's fine for listening to lectures by Steven Hawkings, but not for VST tutorials. The good news is it has an extensive help system built into it so your questions are usually answered very quickly.

UI: Really nice help system, although the text is pretty tiny overall. It often breaks from Mac/Windows styles for no apparent reason, which can be somewhat confusing but with the help system it's fairly easy to overcome. Also, thank god there are tons of amazing tutorials up. All developers should have this. The UI is attractive and although somewhat cluttered I can't imagine making it a lot better due to the depth of functionality. You won't be doing too much random mousing around without the tutorials so I suggest going there first.

Sounds: first thing you notice is that the default drum kit/beat sound great. Full, natural and it almost coaxes you to start playing along with it. Even the electronic kit/styles have a somewhat natural non machine kind of sound to them. Hard to put into words but it was probably because the hits had unique velocity and not just regular and accent volumes. The sound is overall very good, but the electronic stuff was a little tame compared to some of the kits that come with Battery Electronic Drums II. I found myself wishing for a filter gain control and some dirt. No matter, it sends MIDI out so all my Battery sets are available to me easy as pie.

Right off the bat I went and started editing the drum synth sounds with mDrummer's on board synth (it has both samples and a synthesis engine) and it was a dream to program. Couldn't have been easier to get a nice interesting Bass Drum tone right off the bat by combining a sine osc and a noise osc. Again, I wouldn't have minded some effects like tube distortion. I love the mScratcher module which will come in handy for my weirder sounds. Some decent effects are on board here, but I was surprised that although you can put effects on each drum there’s no sort of master compressor for the output. Easy enough to put PSP’s Vintage Warmer after it and beef it all up even more.

It comes with a generous library of kits and with the ability to make your own kits and combine kits plus your own synth drum tones... the choice is pretty vast. You can also import your own samples and even set up multi-samples.


If you’re hoping to turn this thing on and select a preset and get the most out of it, you might be a bit disappointed. mDrummer calls itself a drum studio and for good reason. There’s a lot going on. Good thing is it’s all well laid out and covered by a combination of tutorials and the help system.

My favorite function is the “Rhythm Generator.” This is why I got mDrummer and it does not disappoint. You put in a basic snare/bass beat and hit “Process All” and it automatically generates a bunch of very useful variations and fills based on your “seed.” The basic beat editor is as easy as pie, though I found myself wishing it had a live input with a metronome style of input. No matter, I can easily make one in Live and export the clip as a .mid file and import it into mDrummer. If you’re super lazy, as I sometimes am, you can import .mid files from a 3rd party collection like Groovemonkey.

One thing is that as far as I can tell all the processing happens at the moment you hit “process all.” This is mostly fine but it would be really cool if there could be some chaos and variation happening in real time. It’ll also listen to your playing via midi input and adjust itself accordingly though I didn’t have much time to play with that. I do a lot with guitar anyway.

Once you get your beat and variations you can sequence them out in two ways. MIDI input or the Song Structure editor. Both seem equally easy but I’ll probably stick with mDrummer’s midi entry style because I like to create a basic song structure and jam

Hey all (and the MeldaProduction Team), .

There was a short window in which the company, MeldaProduction, requested information/opinions from users, asking if there would be any interest in a pay by the month opportunity (I can't remember exactly, but something like $9.99/month and a yearly rate as well)... anyways, the chance to offer input was fairly short and I was just wondering if anyone else had seen this question posed by MeldaProduction recently and what their opinion was, if you don't mind sharing.

Hi, well, the thing is, maybe the audio world (being extremely conservative) isn't prepared for it yet. You'd loose free-for-life licences, so basically our licence policy is now so good, that well pretty much cannot get better, and you'd just loose all that with subscription model. Plus there are pretty big technical challenges. But I'm not saying it won't happen, just probably some day later, when people are ready for it.

This is one of the best Demo's I've ever tried.

Mdrummer is the go to Drum machine. I've got Maschine Studio, but I get tired fast with trying to come up with some new drum beats. Welcome to Mdrummer one of the best Vsti Drummer with customization. You can't beat this, you could take Maschine Studio various drum kits, and put them with ease inside the Mdrummer and come out with greater drums. This is the true next thing to a Real Drummer.

GOD Almighty bless.

P.S hope they come out with a MMelody, the instrument version of Mdrummer with all the randomization and generators. Peace.
