Transform your modular synthesizer with the legendary 4MS Pingable Envelope Generator – the dual envelope powerhouse that revolutionized clock-synced modulation in Eurorack systems. This original 20HP version delivers unparalleled creative control with its unique "ping" timing system that automatically syncs your envelopes to any clock source or tap tempo. One of the centerpieces of rhythmic patches!

It's got --

• Dual Independent Envelopes: Create complex, evolving patches with two fully-featured envelope generators in one module
• Revolutionary Ping System: Set envelope times instantly by tapping or sending clock pulses – no more fiddling with tiny knobs to match tempo
• Full CV Control: Shape, skew, and time division parameters all accept CV for dynamic, living modulation
• Versatile Waveshaping: 9 different envelope curves from exponential to logarithmic, plus unique interpolated shapes for character beyond standard ADSR
• Multiple Gate Outputs: End-of-Rise, End-of-Fall, and Half-Rise options multiply your triggering possibilities

Whether you're crafting rhythmic percussion patches, designing evolving ambient textures, or need precise envelope timing for sequenced leads, the PEG delivers studio-quality results with intuitive hands-on control. The ability to multiply or divide clock signals from /32 to x16 makes it equally powerful for a ratcheting LFO or EG.
