Its four channels each operate independently, with the mode set per channel. That means a single unit can simultaneously take on different roles — envelopes, LFOs, random voltages, and recorded manual movements. Each channel can be set to one of the following five modes: - ADSR Envelope - AD Envelope - AD LFO - Random Voltage - Recordable Knob Voltage Control In every mode, the output waveform is continuously variable between logarithmic, exponential, sine, trapezoid, and square. Signal level and polarity are adjusted with an attenuverter, and each channel can take external CV via its own `MOD` input. ## The Four Modulation Channels ### ADSR Envelope / AD Envelope In ADSR Envelope mode, the channel works as an envelope generator with four parameters: attack, decay, sustain, and release. AD Envelope mode is a two-parameter configuration with attack and decay only. The envelope time range is `1.5ms` to `4min`. ### AD LFO In AD LFO mode, the channel works as an LFO. The range is `88Hz` to `7min`, covering everything from speeds that reach the audio range down to cycles that take several minutes, all within one mode. ### Random Voltage In Random Voltage mode, the channel generates random voltages. The range is `2kHz` to `2min`, so you can set anything from audio-rate speeds to slow changes that unfold over minutes. ### Recordable Knob Voltage Control In Recordable Knob Voltage Control mode, the knob movement itself is recorded and can be played back as a modulation signal. Rather than a fixed shape like an envelope or LFO, it lets you treat a hand-drawn gesture as parameter movement. ## Continuously Variable Waveforms The waveform each channel outputs can be varied continuously between the following shapes: - Logarithmic - Exponential - Sine - Trapezoid - Square Because this is continuous rather than a stepped switch, you can set envelope curves and LFO shapes that fall between these shapes as well. ## Attenuverters and MOD Inputs Bipolar attenuverters are provided for the modulation input and for each channel's output. They handle polarity inversion as well as attenuation, so you can derive both positive-going and negative-going modulation from the same signal. Each channel also has a dedicated `MOD` input, letting you control that channel with external CV. ## Output and Input Voltage Ranges - Envelope output: `0/8V` (`8V/0V` when inverted) - LFO / random output: unipolar `0/8V`, or bipolar `-5V/+5V` - Input voltage range: `-5V/+5V` ## Demo Video Below is the Envy Machine demo video from RYK Modular's official YouTube channel. It covers the module's features and sound comprehensively, so please take a look.

RYK Modular makes modules that are unique yet genuinely practical. Their most talked-about module right now is the M185 — a classic sequencer reimagined in a form that feels right at home in a modular rig. Their VectorWave FM oscillator module is another standout. - [RYK Modular Website](https://www.ryk-modular.com/) - [X: @RYKModular](https://x.com/RYKModular) - [Instagram: ryk_modular](https://www.instagram.com/ryk_modular/) - [YouTube: RYK Modular](https://www.youtube.com/@RYKModular) ![Logo: 電氣美術研究會](https://imgs.takazudomodular.com/images/p/denbi/revisions/production/r1-c35cb4eaf5f608733e69add54a5d951fcd8e67a5b52edf89e605c75dd0a0fd42/820w.webp) ## Bonus: Modular Accessory Set by 電氣美術研究會 (Denki Bijutsu Kenkyukai) Included In the hope that more people will get hands-on with modular synths, we have teamed up with 電氣美術研究會 to bundle a modular accessory set with this product. The contents vary by season — patch cables, power cables, a dress-nut sample set, a mono splitter, and more. The set is included with the product, so please give it a try! - [電氣美術研究會](https://ears-modular.com/) That concludes the product details for the Envy Machine. It's a module that packs envelopes, LFOs, random voltages, and recorded knob movements into four independent channels in 12HP.
