Description
Introducing the Cosmotronic Delta-V, a versatile powerhouse for modular synth enthusiasts. This two-channel function generator with integrated VCA is designed to elevate your sonic explorations. It's not just a module—it's your gateway to a universe of sound possibilities.
Whether you're crafting dynamic AD envelopes, sweeping LFOs, or nuanced slew limiters, the Delta-V offers unparalleled flexibility. Dial in precise attack and decay times, or shape your sound with an adjustable characteristic curve that seamlessly transitions from exponential to linear to logarithmic, providing a rich palette of tonal variations. The switchable trigger or loop mode further amplifies its adaptability, allowing for both rhythmic precision and experimental textures.
Harness the power of the bipolar attenuator for nuanced control over function outputs, and utilize the CV inputs to modulate attack and decay parameters with ease. The Delta-V also features dual VCA signal inputs and trigger and slew signal inputs, making integration into your existing setup a breeze. Each channel is equipped with an EOC output, supplemented by a sum output for added versatility.
Designed to fit seamlessly into your Eurorack system, the Delta-V is compact yet robust, consuming just 70 mA from both the +12 V and -12 V rails, and occupying a slim 10 HP width. Whether you're a seasoned synth architect or a curious sound explorer, the Cosmotronic Delta-V is your ticket to crafting compelling audio landscapes.
