It is capable both of processing and, when the filter is self-oscillating, generation of synthesised sounds such as drums.\u003c\/p\u003e\n\u003cp\u003eThe VCF section contains a State Variable Filter (similar to my other designs) – this offers switchable Low or High Pass responses and covers the full audio range. It is temperature compensated \u0026amp; tracks 1V\/Oct accurately. The Resonance\/Q is voltage controlled with a linear response up to self-oscillation – this creates a pure sinewave, useful for synthesis.\u003c\/p\u003e\n\u003cp\u003eThe VCA is linear in response and takes the Low\/Hi-pass output from the VCF section. It can either be set, via rear jumper, to a clean response (gain from 0 to +1) or saturation (gain from 0 to +1 then +\/-5V zener clipping beyond – unity at approx 10 o’clock rotation).\u003c\/p\u003e\n\u003cp\u003eThe Filter, Q and Amp sections each have a CV Modulation depth control with switchable polarity (centre off) – the Filter has an additional 1V\/Oct control input. In addition there is a simple variable-decay Envelope Generator which can be fired either with the manual Trig button or via the Trig input – this has a comparator so triggers on any signal over c.+1V. Decay time is variable between approx 15mS and 3Secs with an amplitude of 0 to +10V. The envelope is internally routed to modulate the Filter and Amp sections via individual depth controls – it could be manually patched to QCV with a 0.75″ shorting bar or cable.\u003c\/p\u003e\n\u003cp\u003eWhen Q is set to full, the self-oscillating filter makes good sound generator – it can also ring when set below self-oscillation \u0026amp; fed with sharp edges such as gate signals. A basic drum synth can be achieved with self-oscillation and the decay envelope opening the VCA – try varying how much the envelope modulates the filter cutoff too. You can feed the main output back to the FCV input to self-modulate, resulting in an interesting peaky waveform.\u003c\/p\u003e","brand":"Bugbrand","offers":[{"title":"Default Title","offer_id":47616252313770,"sku":null,"price":999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0020\/5199\/7743\/files\/JoytouchMini.jpg?v=1762965798","url":"https:\/\/www.noisebug.live\/products\/bugbrand-joytouch-mini-system","provider":"Noisebug","version":"1.0","type":"link"}
