ABOUT THE COMPONENTS

Both oscillators of each voice are analog, with all their elaborate waveshaping completely analog, and with their
pitches controlled digitally. The noise generator is digital. The two filters, and the overdrive circuit between them,
of each voice are fully analog. The amplifiers are analog. The envelopes and LFOs are digital. Their design
allow them to go well into audio range.

COMMENTS ON THE SIGNAL PATH

The signal path from the oscillators to the audio outputs is completely analog. The signal path from the external
inputs to the audio outputs is also fully analog. The digital send effects are parallel to the main audio path, and
the wet signals from the digital send effects are mixed with the dry analog signal before the main output stage.

ABOUT THE OSCILLATORS AND FILTERS

The oscillators are constructed from the ground up, in order to obtain a richer sound and provide more features.
The ladder filter is based upon discrete low-noise transistors, the multimode filter uses high-quality VCAs. The
combination of tradition and innovation gives a unique sound with many possibilities not found in other analog or
digital synthesizers.
