RYK Modular - Envy Machine

ENVY MACHINE is a compact modulation powerhouse with four independent channels, each offering a wide range of modulation options. From envelopes and LFOs to random voltages and unique knob recording, ENVY MACHINE delivers remarkable flexibility in a small Eurorack format.

Each of the four modulation channels operates in one of five versatile modes:

• ADSR Envelope
• AD Envelope
• AD LFO
• Random Voltage Generator
• Recordable Knob Movement

Knob Recording lets you manually animate parameters, capturing expressive modulations to add life and dynamics to your patches.

Each channel includes its own dedicated MOD input, enabling external CV control over parameters such as time, level, waveform shape and more.

Both inputs and outputs feature bipolar attenuverters, allowing smooth transitions between unipolar and bipolar signals with precise modulation depth control.

Shape your modulation curves with continuously adjustable waveforms that morph seamlessly between LOG, EXPO, SINE, TRAPEZOID, and SQUARE.

Technical Specifications:

TIME
• Envelopes: 1.5 ms – 4 min
• LFO: 88 Hz – 7 min cycle
• Random: 2 kHz – 2 min

OUTPUT VOLTAGE RANGE
• Envelopes: 0 V to 8 V (inverted: 8 V to 0 V)
• LFO/Random: 0 V to 8 V (Unipolar) or -5 V to +5 V (Bipolar)

INPUT VOLTAGE RANGE
• -5 V to +5 V

Features:
• 4 modulation channels, each with 5 selectable modes
• Knob Recording (“Ghost Hand”) for expressive, animated modulations
• Dedicated external CV modulation input per channel
• Bipolar attenuverters on all inputs and outputs for flexible polarity control
• Smoothly variable waveshapes: LOG, EXPO, SINE, TRAPEZOID, SQUARE
• Compact, intuitive Eurorack design – ideal for both performance and studio use
