Jamstix is virtual drum software which simulates a drummer inside of your sequencer/DAW. Unlike most other drum modules, which either provide static MIDI patterns or an engine that combines pre-recorded MIDI patterns, Jamstix features a real-time simulation of a human drummer down to the calculation of the time it takes a drummer to move an arm from drum A to drum B. This means that arrangements created with Jamstix are always humanly playable (no ten-armed drummers) and also always unique and varied since they are created based on rules and not static patterns.

The "song builder" function can create a full drum arrangement with many parts and fills in seconds and the included sample engine offers incredibly realistic sound reproduction.

A real-time 3D drum kit with realistically moving drumsticks, cymbals and pedals provides a new level of immersion as you work on your songs.

Various expansions are available for Jamstix, including hand percussion, linear groove composition, Metal kits/drummers and much more.

Whether you are a hobbyist or a professional, whether you are in need of a jamming partner or a drum arrangement tool, a student wanting to learn more about drumming style or a songwriter needing to create a complex and unique drum track quickly, whether you have no drum module at all or have every high-end drum library on the market and wish to get the most realistic grooves out of them, Jamstix is the tool for you.

Advanced Virtual Drummer:

  • Real-time groove composition using dedicated style and drummer modeling (not static patterns).
  • In-depth drummer limb simulation, including triangulation of hand movements, ensures that the grooves are always humanly playable (no ten-armed drummer here).
  • Advanced feel modeling includes sound-specific pocket delays, power and timing variations and can play ahead, on or behind the beat.
  • Real-time fill generator produces unique fills (no static patterns used) that match the style and drummer in use.
  • Streamlined interface with real-time 3D drum kit for editing as well as just watching the drums play.
  • Part-based arranger with transition and repetition fills, liveloop technology as well as drag-&-drop MIDI export.
  • Limb-centric bar editor allows fine-tuning of notes without need for MIDI export/editing in host.
  • Extensive MIDI controller mapping allows in-depth remote-control of the style, drummer and mixer.
  • Comes with over 70 styles (rock, funk, afro-cuban, blues, jazz, electronica, brazilian, breakbeat, country, R&B, Motown and many more) and 17 human drummer models, expandable via future Paks.

High Quality Sounds:

  • Built-in high-quality drum sample player with multiple velocity layers and controllable ambience.
  • Built-in mixer with FX.
  • Extensive sound library that can be expanded via expansion Paks.

Integrates With Other Sound Modules:

  • Flexible mapping allows 'driving' of other drum plugins, such as BFD, Superior, EZDrummer and Addictive Drums. Combine the sounds of your favorite drum plugin with the jam power and realism of Jamstix.
  • Allows creating kits that use a mix of external sounds and Jamstix sounds. For example, you can built a kit that uses EZDrummer drums and Jamstix percussion sounds and cymbals.

Interactive Jamming
Jamstix can interact with your MIDI or audio input by adjusting velocity and using play rules, such as hihat/ride switching and snare head/sidestick switching as well as rhythm reduction giving you the feel of playing with a human drummer.

E-Drum Support
Jamstix can be used with any e-drum kit and fully supports the TD-20 V-Drums, including bow/shank hihat, foot splashing, aftertouch cymbal choking and snare position sensing.

Supports Your Existing MIDI grooves
Jamstix can import your existing MIDI drum grooves as well as Jamstix 1 rhythms and use them as styles for playing by the drummer models. This means a static 1-bar MID file groove comes to live by being played with the feel, accents and fills of the Jamstix virtual drummers.

There is no other machine or software that drums as realistically human as Jamstix. Out of the box it will do some strange things because you don't know what you're doing yet. An example of that would be not changing your DAW host BPM to a speed that's appropriate for the R&B style you just chose. There are a lot of control "surfaces" and many of the adjustments interplay with others so it takes some time to learn how to direct Jamstix to drum for your song optimally. Get on the forum and the developer Ralph and other experts will give you exact instructions on how to achieve your goal.

I recommend the Jamstix Studio bundle. It includes almost all the "drummers", "styles" and samples. I have Superior Drummer but tend to use the Jamstix "kits". They sound quite good, I'm especially fond of the Bonzo Pak kits.

I have BIAB, Jammer, pattern books and drum MIDI collections. I've programmed from scratch, played in parts on a keyboard, played parts in from pads. Jamstix is a better way. I use it to practice bass styles, backing for practicing covers, laying down drums for original compositions and for live jamming via a foot controller.

First up, let me say that I am no drummer, but I do know what I like when I hear it. And this is the first piece of drum software that I have tried that I was able to get something that inspired me to go deeper. This is almost like having several drummer just sitting around and waiting for you, not only that but no ego's to get in the way. Seriously though, this is a fantastic piece of software, not the easiest to use or the quickest to learn, but if you spend some time with it, the manual and if needed their forum, you will be rewarded with the ability to pretty much do anything you need with drums and percussion.

Some of the more impressive features to me are the fact that Jamstix patterns are always human playable. The included algorithmic 'drummers' do indeed have their own character and flare, which adds interest. The fact that it can drive other drum programs, import and export MIDI files, and it can create drum patterns driven by a audio file input are all pretty hefty tools. Drum kits can be edited, as can the generated patterns. Overall there is just a lot of value for the money here and a lot of power for song creation.

The only reason I didn't give it a 10 out of 10 is the GUI, it's not exactly terrible, just a bit hard to understand at first. A bit intimidating if you will. But, some time with the manual clears most of it up rather well.

Now they say you should always save the best for last so here it is. What I find to be the best thing so far about my purchase of Jamstix is by far the customer service. It is top notch, very prompt and friendly reply's and quick turn around times to any questions I have asked.

Would I recommend Jamstix to anyone looking for Drum software?

Absolutely I would.

A week later and everything still applies. A great piece of music software from a responsive indie developer.


Original review:

Just started working with it this weekend; about 16 hours total. Its been a long time since a piece of software for my DAW left me totally gobsmacked so forgive the long post.

I've been evaluating Jamstix along with TabTrax using Toontrack SD2 and SaviHost to get a sense of workflow outside of Cubase for just creating drum arrangements that I can save for importing into Cubase after I have a basic groove and rudimentary arrangement worked out.

I'm not a great drum programmer; it's never been as intuitive as actually playing a simple backbeat on a kit. Therein, however, lies my dilemma. I can play solid enough rudimentary backbeat but not much more. I also don't have the room in my flat to set up my Roland kit nor would my downstairs neighbor much like it. As a result I've been searching for a relatively intuitive way to lay down drum parts. It appears thus far that Jamstix will allow me to adopt the kind of workflow I was struggling to achieve using EZplayer and TT Solo. I've only just scratched the surface of Jamstix and it feels like it will only become more useful the deeper I get into it.

I found a drum tab that had the general vibe I was going for to seed my drum part.

Pasted the drum tab into TabTrax and auditioned it inside TabTrax to make sure the tab wasn't wonky.

Saved the tab as a MIDI file with TabTrax.

Opened Jamstix using SaviHost and chose a kit from TT SD2

Imported the MIDI file I saved with TabTrax.

Auditioned the Jamstix drummers and then...

... it got really interesting.

The parameters Jamstix provides to mold a drum part into something suitably inspiring is amazing.

After the drum track was where I wanted it in Jamstix, a very good start, I saved it as a MIDI file, opened Cubase, imported the file, worked out a simple bass guitar part to start getting a better sense of things, recorded the bass part so I don't forget it, then did a little drum editing in Cubase, went back to the bass part for a bit, and so on.

I had some pretty serious reservations about using tabs or canned MIDI files; anything that I didn't put time and effort into programming or playing myself. Jamstix requires plenty time and effort, however, to make a track your own. Once a MIDI file is loaded into Jamstix you can start working with it to make it your own. Starting out with a simple Richard S. or Charlie W. style backbeat you can gradually add accents, cymbals, hi-hat, toms, embellish, take away then add again.

Working from a converted tab was successful so next I loaded a MIDI file from the Steve Ferrone Platinum Samples MIDI Groove Library and after working with it for about an hour I knew I didn't have to concern myself about feeling like I was cribbing. I compared the file that I derived from the MIDI groove to the original, there was a significant difference. It retained a family resemblance and the vibe I sought out to begin with but it was quit distinct from the original. I even listened to the bass part with the original MIDI file and it still worked, albeit, in a very different way. The analogy I'll use is a drummer coming in, laying down a groove, and after working with him for an hour or so, getting the part where I want it to be without completely ignoring his creative input.

I spent most of my 20's playing out and recording in garage/indie bands with drummers who couldn't stop "jamming" enough to critically listen to the song the band was playing or even in between songs to listen to suggestions that would allow a more sympathetic approach to the needs of the song verses their ego.

There were, however, a couple of exceptional drummers who would listen, try well thought out variations, not just "jam" along, and actually be a partner in helping the band write and arrange. They didn't fall into the stereotype of, "What do you call someone who hangs out with musicians?" They were solid musicians not "just" drummers. Working with MIDI files and converted tabs in Jamstix vs other programs that use loops or emulate drum machines reminds me of working with those exceptional drummers as apposed to the chuckleheads.

IMO, TabTrax + a couple of supplemental MIDI Packs + Jamstix + TT SD2 = the best you can get when you can't get a good drummer with a well tuned kit.

My complaints thus far are few. I tried to get Jamstix to play from inside Cubase and it didn't work until I used jBridge. It would also be nice to have expansions that only include players and styles without any Jamstix drum kits. Small complaints to be sure, however...

Toontrack SD2 is my primary drum program and I have all the SDX libraries, only two of the EZX. Jamstix doesn't include drum maps for any of the TT SDX libraries outside of NY v2. I've already modified the Allaire kit mapping in Jamstix for Music City, renamed it accordingly and saved it but it appears that not all articulations are available for mapping.

To get started with Jamstix for $99.00US is a bargain. Add a MIDI library for $30-$40, and TabTrax for another $30 and you are still in bargain territory.

Here's the best part of Jamstix:

Timely feedback and support from the developer; the best I've experienced since I started patronizing indie developers.

I had been manually putting my drums together before I bought this, and after hearing a few pieces put together by people stating they used Jamstix, I had to go out and buy it!

It creates variations and fills in real time rather than rely of stringing MIDI files together, and it will jam along with either MIDI or audio from another track in your DAW which is a great feature. You can also put together your own patterns, either from a MIDI file or by dragging and dropping in a cell matrix.

First impressions were that the UI is not that user-friendly. This seems to be a common criticism of it and one that most people hope will be addressed in future versions. It's not that it's difficult to use, it's just that it's, well...ugly...

The sounds that come out of this are fine - very well sampled drum kits with a very realistic sound. If I had to criticize the sound it would only be that there is not enough variation between kits - maybe a broader range of kits would have been more useful. However, if you don't want to use the Jamstix kits, you can always get it to trigger another sampler that does have the sounds that you want.

Nothing wrong with the documentation that comes with this, but it is maybe a little difficult to understand because it uses screenshots of the UI. If the UI itself was more clear and well laid out, then I'm sure the documentation would seem a lot better.

For presets you get the various kits, the various drummers, and various styles. I think these could be expanded greatly, particularly the variation in kits and more than one example of each style. Having said that, there are plenty of tweakable parameters, so if you don't like it you can change it.

Customer support from Rayzoon is excellent - they have got it exactly right - if the customer has an issue they address it. There are far too many companies out there who are more interested in selling their product than dealing with customers.

Value for money? Absolutely! This is a steal at less than $100!

As for stability, I've had no problems with this at all. It's rock solid and isn't too resource hungry, even when you load some of the larger kits.

I'd recommend this software to anyone looking for a flexible, virtual drummer.Read more

Jamstix 1 was developed from the idea of an "intelligent" jamming buddy, responding to the intensity of your playing in a life-like manner. In time it grew well beyond that, incorporating an arranger section enabling you to give your drummer detailed instructions of what to play, and when to play it. However, as a result of this organic growth the user interface was a bit convoluted, to say the least, and much labour was required to get the results you wanted.

Jamstix 2 has been redone from the ground up -- it's got the same basic ingredients and capabilities, but done in a completely different and much more user-friendly manner. In the transition, it has gone from being jam-centric to arranger-centric, a very good thing for me personally since I don't use the jamming features (much). Instead, I now have a number of competent session drummers I can really sit down and talk arrangements with.


Leaving the live input (jamming) capabilities aside, there are a huge number of things that affect the way a certain part (one or more consecutive bars) in the song structure is played:

- Load a style to decide the basic rhythm -- there are about 50 styles included at the time of writing. These styles are not just patterns: Each style is customizable through a set of controls that is unique to each style. Some styles offer only minor variations, others are really a package of similar styles where you need to go exploring thoroughly in order to realise the possibilities. The March style, for instance, have both foot and snare settings of "March", "Baiao", and "Gadd" -- allowing you to use it for everything from western marching band music to Brazilian Baiao to a creditable emulation of Steve Gadd's famous drumming in "50 Ways to Leave Your Lover".

- Within the style, the playing for a bar is layered into "groove", "accent", and "fill" aspects: Each aspect has its own set of customization controls, and fills can be played in solo or in combination with the other aspects.

- As if this didn't create variety enough, now it's time to choose between the 9 available "drummers". These are models of real-life drummer behaviours that greatly affect the end results. Each drummer has his own ways to add syncopation, accents and fills to the drumming. In addition, you also have access to a totally "brainless" guy, and one who is a machine. The latter is the only one not taking human limitations into account when playing, but does things you would normally need a trained octopus for.

- Still not satisfied? Then go into the bar editor and edit drumming events individually to correct those small annoyances in an otherwise good performance. Manual edits, as well as entire bars, can be locked from further changes by Jamstix.

- Are we done yet? Not quite - you can also add groove maps to all or part of the song, and make global shuffle and general timing adjustments. In addition, there is the possibility to load your own MIDI files and have Jamstix modify those instead of using the built-in styles.

Yes, Jamstix 2 is deep - VERY deep - but in comparison to Jamstix 1, you can get the overall structure of a song together and the drumming in the ballpark much quicker. It is also really easy to move things around in the song structure without as much fear of destroying what you already have and like.


How does Jamstix 2 sound? The answer is, any way you like. You can use only its included drum kits, or sub-host a drum sampler of your choice within Jamstix 2, selecting drums from both sources to work together - use the percussion from Jamstix 2 together with a percussion-less kit in Battery 3, for instance. You can also go MIDI-only out from Jamstix into a drum sampler loaded separately in your host/sequencer.

The basic version of Jamstix 2 contains just one kit, but it is very, very good and "live sounding", although it will not suit all production styles. The XL version also contains all add-on kits released for Jamstix 1, including brushed kits (necessary for some jazz & swing styles) and close-miked kits. Overall, the drum sound quality is really good, competing with the best of the dedicated drum sample libraries, although naturally a bit generic in nature. You should really consider the XL version standard, and the basic version a "stripped down" one.


Ah, the old stumbling block... This product really needs a lot more readily accessible how-tos and tutorials. Besides, the sheer rate of feature add-on and improvement means it's almost impossible to keep the manual up to date. But let's face it, the Jamstix users are an enthusiast crowd, and some visits to the Rayzoon support forums should be obligatory!

There, I've run out of space already with nothing more than scratching the surface. So I'll end just by saying that Ralph Z of Rayzoon is the friendliest and most dedicated man in the entire business. There! Go Buy Jamstix!Read more
