ANALOG KEYS SIGNAL PATH
Below is an image outlining the signal path of Analog Keys.
ABOUT THE COMPONENTS
Both oscillators of each voice are analog. All their elaborate waveshaping abilities are completely analog, with
digitally controlled pitches. The noise generator is digital. The two filters and the overdrive circuit between them
are completely analog. The amplifiers are analog. The envelopes and LFOs are digital. They are designed for
maximum efficiency and versatility.
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 completely 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 designed and built from scratch, in order to obtain a lush sound and provide an array of con-
trol features. The ladder filter utilizes discrete low-noise transistors, the multimode filter uses high quality VCAs.
The combination of tradition and innovation ensures a unique sound with a wide range of possibilities. For a
