These are optimized for 5 volt analog control signals, but can accept up to +\/-10 volts.\u003c\/p\u003e\r\n\u003cp align=\"left\"\u003eThe Size parameter moves all four BPFs in parallel. This affects the overall size of the filter’s ‘mouth’.\u003c\/p\u003e\r\n\u003cp align=\"left\"\u003eArticulators X and Y work together to select vowel tones from a two-dimensional map related to the \u003ca href=\"http:\/\/en.wikipedia.org\/wiki\/IPA_vowel_chart\" rel=\"noopener\" target=\"_blank\"\u003eIPA Vowel Chart\u003c\/a\u003e. For optimum control, these inputs can be connected to an analog joystick controller or two channels of a MIDI-CV converter. The ideal voltage range for controlling Articulators X and Y is +\/- 2.5 volts, or 0..+5 volts. See the Patching Guide for further detail.\u003c\/p\u003e\r\n\u003cp align=\"left\"\u003eSuggested signal sources for the CV inputs are LFO, envelope generator, MIDI-CV converter, analog joystick controller, etc…\u003c\/p\u003e\r\n\u003cp align=\"left\"\u003eQ. How has it changed from version 1 (released in 2012)?\u003c\/p\u003e\r\n\u003cp align=\"left\"\u003eA: The control processor has been optimized for full control with fewer parameters. The functions of Articulators I,II, and III have been condensed into Articulators X and Y. The BPF on\/off switches have become obsolete in the new order and have been assimilated. In addition, input and output signal levels have been standardized. In all other regards, the filter bank is identical.\u003c\/p\u003e","brand":"RARE WAVES GRENDEL","offers":[{"title":"Default Title","offer_id":41908101644461,"sku":"rare_waves_grendel_formant_filter_v2.2_silver","price":230.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3449\/7197\/products\/gff2.2-silver-and-black-1024x825_1.jpg?v=1665114828","url":"https:\/\/www.detroitmodular.live\/products\/rare-waves-grendel-formant-filter-v2-2-silver","provider":"Detroit Modular","version":"1.0","type":"link"}
