The sine can be modulated in a linear manner from the triangle wave of the VCO and by LFO2 in an exponential manner at the same time !\u003cbr\u003efrom the factory the socket labelled \"LFO1\" outputs the inverted LFO1 signal. But as the module has several internal pin headers available even another signal may appear at this socket by changing the internal module patch. These six pin headers are available: LFO1 output, LFO2 output, ADSR output, inverter input, inverter output, output socket. The internal default patch is LFO1 -\u0026gt;  inverter input, inverter output -\u0026gt; output socket (i.e. socket = inverted LFO1). But even another signal can be patched to this socket (e.g. inverted ADSR, non-inverted LFO1, inverted or non-inverted LFO2). It is also possible to add a blind panel next to the A-111-5 with a couple of sockets that are connected to the corresponding pins of the A-111-5 pc board. The in- and outputs of the VCO, VCF and VCA are not available as pin headers because the VCO, VCF and VCA are internally connected in the circuit which is used in this module.\u003cbr\u003eA more detailed description of the module can be found in the user's manual A111_5_man.pdf\u003c\/p\u003e\n\u003cp\u003ePay attention that the orientation of the bus connection cable of the A-111-5 is different compared to all other A-100 modules\u003c\/p\u003e","brand":"Photosynthesis","offers":[{"title":"Default Title","offer_id":48199091486907,"sku":null,"price":350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0691\/2986\/3355\/files\/DoepferA-111-5minisynthesizervoiceEurorackModule.png?v=1785885654","url":"https:\/\/www.photosynthesisolympia.com\/products\/doepfer-a-111-5-synthesizer-voice-used","provider":"Photosynthesis","version":"1.0","type":"link"}
