Eurorack ADSR Module
Features
- Attack-DeCay-Sustain-Release Eurorack ADSR Module
- Takes in Gate signal, generates CV to VCA
- Attack, decay, and release pots control speed
- Attack, decay, and release times can range from 200ms to 16s
- Sustain pot sets the sustain voltage level
- LED dims to level
- 3U tall, 6 HP wide
- 555 Based design
- Benjie Jiao MiniADSR
- Original was based on Barry Klein design
- As built by schmitzbits design - "The Fastest Envelope in the West"
- Benji's build has a three card stack-up and is 4 HP wide
- This card is wider but uses 2 cards
Rev 1 Checkout
- Drive with Erica Synths EDU Sequencer
- GATE Out output
- Using 1 M linear pots instead of 2.2M log pots
- A, D, r pots should have been log pots
- Controls are are "touchy"
- Sustain pot is linear as it should be and "works" but is backwards
- ADR series resistors are 220 Ohms but should be 100 Ohms per schmitzbits note
- C3 is 4.7 uF
- Does not have 1M that is dashed line on schmitzbits schemativ
- ADSR controls
- A pot full CW
- D pot full CW
- S Pot mid
- R pot full CW
