GH Services is an authorized Rayzoon dealer. Rayzoon products are made in North Carolina by Rayzoon Technologies, which was founded by Ralph Zeuner in 2001 to create software to simulate human musicians in order to facilitate song composition and arrangement. The goal was to devise rule-based systems that would react to MIDI or audio input and allow you to customize the response.

GH Services is located in the Niagara Region of Canada, near Toronto and the Canada-U.S. border. Owner Greg Holmes is a long-time musician, ready and able to help you with any questions you have. More about GH Services here.

Jamstix 2 - Virtual Drummer VSTi     BUY NOW!

The flagship product is Jamstix 2, Rayzoon's ground-breaking virtual drummer VSTi that runs synchronized with your sequencer and features in-depth real-time modeling of various styles as well as human drummers with their own habits, accents, and fill characteristics. Together, they can create thousands of realistic drum performances, each one editable down to the last hit - thanks to the built-in limb-centric bar editor. ("Limb-centric" means that Jamstix models a real human drummer with arms and legs.)

This unrivaled drum simulation is complemented by a high-quality sample player with 1.5GB of samples (in the XL version) as well as a VSTi subhost that can 'drive' your favorite drum module with the brain power and arrangement functionality of Jamstix 2.

And it can jam interactively with your MIDI or audio input, giving you a realistic performance that varies with what you play.

Features and Specs of Jamstix 2

Advanced Virtual Drummer VSTi

High Quality Sounds

Integrates With Other Sound Modules

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!

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 life by being played with the feel, accents, and fills of the Jamstix 2 virtual drummers!

SOS The sensation of having a virtual drummer respond to the dynamics of your playing is quite remarkable, and Jamstix throws in some genuine surprises that are very un-machine-like. (SoundOnSound Magazine 11/05)
KEYBOARDS It interacts with the play style of the user on a high level and, when used with high-end sound modules, allows a degree of realism that would otherwise require an extreme amount of hand editing. (KEYBOARDS Magazine 11/05)
Sven Bornemark (Creator of Steinberg Groove Agent) "I wish to express my sincerest congratulations to the radical, new and fresh thinking behind Jamstix! You obviously know how to use a computer for the benefit of fellow musicians. While the rest of the world seems to be concentrating on endless virtual synthesiser emulations, you're taking things several steps further."

Here are some quotes about Jamstix from various message boards and e-mails:

"I don't know if this will get to you guys, but I just wanted to say thank you for such a cool (and inexpensive !!!) program. If everyone made apps and wrote code like you guys do, things would be a lot simpler in the PC music world. I love playing music, NOT fiddling with the software! You guys ROCK! Thanks again!"

"I plug in my guitar, set Jamstix on Free Jam and I swear its fifteen minutes later! So, I try it again, and the next thing I know my wife is standing at the door asking if Iím coming to bed, since I told her Iíd be up an hour ago. I donít think itís the liquor. Any suggestions? I love this program!"

"This is the best VST instrument I have ever used, period. I'm having to redo all my old songs using Jamstix and BFD now, and I'm enjoying every minute of it. What a quality product, please keep up the good work."

"Very human sounding and the way it follows your playing dynamics is pretty much exactly like a real drummer would."

"See, this company rocks! You need to check out the Jamstix forum and see how great these guys are. They take care of things and are so nice about it."

"I must say if THIS is what your customer support will continue to be like (and it's basically only demo users here), you are doing the most awsome job I've seen in quite a while! Should almost be worth it alone to buy your stuff!"

"This is simply the best support I have ever witnessed."

"Fantastic product... Cannot believe it's so affordable !!!"

"My drum tracks will never be the same again..."

"Generates very good and varied grooves. Even when building your own rhythms from scratch you can get very good results fast. And the sound is great, just the right amount of ambience!"

"I have the feeling that Jamstix will be one of the most important VSTi in years."

"I pre-ordered within 2 minutes after reading it..."
