Rayzoon Technologies has released Jamstix, the virtual drummer VSTi that allows real-time jamming with MIDI or audio-in as well as the arrangement of complex, realistic drum tracks synchronized with a VST host/sequencer.

Jamstix has its own sound engine with over 380MB of multi-sampled drums with controllable ambience but it can also sub-host other drum VSTis, such as BFD or DFH Superior, bringing a whole new level of interactivity and expressiveness to these sound libraries.

Extensive jamming capability: Jamstix analyzes MIDI input to identify chord patterns and velocity as well as audio input (velocity only) in real-time and develops rhythms and adjusts parameters instantaneously, giving you the feel of playing with a human drummer.

The Limb-Priority-Control mechanism ensures that the output is at all times playable by a human drummer. You can layer rhythms and fills and accents as you wish and never have to worry about whether the result sounds realistic.

Built-in arranger allows easy control of rhythms, intros, fills, and endings in sync with your sequencer.

Easy-to-use but powerful rhythm editor allows you to modify or create rhythms. Jamstix comes with a library of 250 rhythms ready to use.

Realistic drumming with just a few mouse clicks thanks to features such as velocity variance, auto-cymbals, random accents, probable notes and automatic switch rules, such as ride over hihat on high velocity, sidestick over snare on low velocity, no-ghosting on low velocity, etc. Rhythms always sound alive and varied!

Extensive pitch and velocity mapping allows the adaptation of any key layout and over 30 MIDI-automation parameters allow control of various aspects of Jamstix by the host sequencer.

Jamstix offers four separate stereo outputs with compression and an additional twelve stereo outputs as pass-through outputs to sub-hosted VSTi that require it. Jamstix also offers MIDI output to the host sequencer as well as export to MIDI file for maximum flexibility.

A demo version and audio examples are available, and a full license can be purchased for US$99.
