4ms Shaped Dual EnvVCA

• Versatile linear, exponential, and logarithmic envelope generator/LFO
• Low-noise, low-distortion, DC-coupled linear VCAs
• 100% analog
• Shape Slider, CV Jack and Attenuverters for fading between Exponential, Linear and Logarithmic envelope shapes without changing the envelope timing
• Sliders and Range switches control Rise and Fall times from ~2ms to > 2 min.
• Time CV jack extends time range: ~400µs (2.5kHz) to ~1 hour
• Independent attenuverters for Rise and Fall time
• Blue/Red LEDs indicate strength and polarity
• Cycle buttons for looping envelopes (LFO)
• Trigger input jack and switch for toggling between AR, ASR, and Cycle modes of triggering
• EOR/F (End of Rise/Fall) gate outputs can be used to chain and sequence events
• Env Level and Offset knobs scale and shift Env Out without changing VCA volume
• Audio In and Out jacks for passing audio or CV through the VCA
• VCA CV inputs to use VCAs independently from the envelopes
• VCA gain internally connected to envelope output when VCA CV jack is left unpatched
• Follow input jacks allow for slew limiting, ADSRs, and exotic filtering effects
• Re-trig jumpers allow for re-triggering during rise phase
