Hexa Core Slope Generator
The world of Envelope generators is a vast field where cultivating a new specie is a challenge that gets harder every day.
We have lots of flavors to choose from: from classical ADSR to Serge-based Slope generators, through the newest digitally controlled multi-stage modules.
The concept behind Fuji is not to create a new flavor, but to offer a big amount of the most primary envelope circuit along with some design decisions to make it a useful, immediate, and always musical tool.
The slope of the envelopes is tuned with logarithmic Attack and exponential Decay. This configuration has been used for years as it follows the non-linearity of human hearing, keeping the dynamics changes always pleasant and natural to our ears.
The range of both the Attack and Decay stages is symmetric, getting a minimum and maximum rise/fall time of either 1.5ms to 1.5s. This range has been also tuned to be musical and precise in most applications.
Gate input chaining adds tons of flexibility to the patch. Groups of synced envelopes can be easily made with a few cables.
Features:
• Six channels
• Fully analog AD envelope generators
• Selectable Hold and LFO mode per channel
• Daisy-chained Gate inputs
• Envelope Level: 8V
• Gate Input Threshold: 1.5V
DIY-Kit-Type:
SMD-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. All SMD parts are pre-soldered, only trough-hole parts to solder. For build guide, more info, videos etc. please check the buttons below.

Product Safety Information
Eurorack DIY Kits
Important Notice & Intended Use
Please read this safety guide before installation or use. This kit is intended for adult users experienced in electronics and modular synthesis. Assembly, including soldering, is required. Proper testing and installation are essential to ensure safe and functional operation. The completed module is intended for installation in a Eurorack-compatible synthesizer system powered by ±12V and +5V.
General Warnings
1. Electrical Hazards:
• Ensure the power supply matches the module’s specified voltage and current ratings (refer to the product manual). Incorrect voltage can damage the module and pose a safety risk.
• Never connect or disconnect the module while the Eurorack system is powered on.
• Wrong polarity can damage your module or system. Make sure the module is connected with correct polarity.
2. Heat Generation:
• The module may generate heat during operation. Ensure proper ventilation within your Eurorack case to prevent overheating.
3. Sharp Edges:
• The module’s faceplate and components may have sharp edges. Handle with care to avoid cuts or scratches.
4. Small Parts:
• Contains small parts that could cause a choking hazard. Keep away from children and pets.
5. Compatibility:
• This module is designed specifically for Eurorack-compatible systems. Connecting it to non-compatible systems may result in damage or malfunction.
Assembly Requirements
• Soldering skills are required to complete the module.
• Ensure a clean, well-lit and ventilated workspace free of flammable materials during assembly.
• Use appropriate tools and safety equipment, such as eye protection.
Testing
• Test the module thoroughly for shorts or incorrect assembly before powering it in your Eurorack system. When the unit has malfunctions due to incorrect assembly, the entire Eurorack system might be damaged. It's a good idea to test it in a separate case with only that single module.
• Use a multimeter or other appropriate tools to confirm proper functionality.
Installation and Use
• Mount securely in a Eurorack case using the provided screws.
• Use only the included or manufacturer-recommended power cable.
• Connect only when the power is off.
• Follow the module's user guide for instructions on operation. Do not exceed the input/output limits specified.
Responsibility
Users are solely responsible for proper assembly and testing. Contact manufacturer support for assistance if needed.
Environmental Safety
• Dispose of the module, its components, and packaging in accordance with local electronic waste regulations.
Liability Disclaimer
• The manufacturer or distributor is not responsible for any injury, damage, or malfunction resulting from improper installation, use, or modification of this product.
