I'm not sure at all how close to the original units it is, anyway I'm quite satisfied with the result. The best way to take advantage of these modules is inside a modular environment like EnergyXT, anyway they can be used with any VST host.
3 Hybrid synth+sample modules are available currently:
Bassdrum The mix fader controls the mix level between the analog (synth) and digital (sample) section. Mapped on B0-C1.
Snare drum The "VAR" button switches on/off an internal LFO which introduces a slightly modulation in the analog and digital pitch parameter to create some variation in the sound to avoid the "gun machine effect". Mapped on D1-E1.
Hihat The mix knob controls the mix level between the analog (synth) and digital (sample) section. The modulation wheel controls the ANALOG pitch (listen to the audio demo). Mapped on F#1, G#1, A#1 (Closed, Pedal and Open).
