Dannysound - MML Filter
Product information "Dannysound - MML Filter"
The Multi-Mode Ladder (MML) Filter is a twist on the classic transistor ladder low pass filter by Dr. Robert A. Moog.
This filter updates the classic 4-pole ladder design to provide Band Pass and High Pass filter responses as well as the traditional Low Pass filter,
this module also adds CV control over the resonance as well as two frequency CV inputs.
The circuit features a fully discrete transistor design with an op-amp buffered output, this allows soft saturation of the input signal
to get the classic overdriven tones of the ladder filter. A bass compensation circuit has been included to retain the bass response in Low Pass mode
when the resonance is increased.
The bass compensation also helps to improve the response of the High Pass filter.
The bass compensation can be removed if the user wishes to have a more classic response (see mods section in build doc).
Features:
• Low Pass, Band Pass and High Pass modes.
• CV controlled resonance.
• Added low frequency compensation.
• Soft saturation of input.
• 2 x frequency CV inputs.
DIY-Kit-Type:
THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. Only trough-hole parts to solder. Make sure to check the build guide before you buy. 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.

Manufacturer "Dannysound"
Dannysound is a small Berlin based electronics company, specialising in the design of Eurorack modular synthesisers.
The aim of Dannysound synthesisers is to provide high quality audio design and performance. There is a focus on warm sounding, soft-clipping saturation inherent to the designs, that can make recorded tracks "sit" better in a mix.
The collection started with a basic synthesiser voice that included reworkings of some classic designs to provide added functionality or better performance where necessary. The future of the collection will focus more on original designs, however, there are also some classic modules that have been requested by users that might make their way into the line-up.
The modules are currently available as kits from Thonk.co.uk and there are plans to start making fully assembled versions in the near future.
I started playing guitar in the 80’s, when it was cool. In the 90’s I studied jazz at music college and then went on to have a glittering career playing some of the worst pubs and clubs, to absolutely no one for 5 years. Then I decided to make electronic music and before I even recorded the first note I got a record deal…they liked the idea! Recorded an album… got dropped!
Had a ton of rubbish jobs until a friend suggested university, so I got a degree in electronics with the specific goal of making musical equipment. Designed guitar effects, valve guitar amplifiers and synths; building polyphonic and monophonic complete systems for a number of years. A friend suggested I design Eurorack modules and with the help of Thonk the brand was established.
The company name was suggested by a friend also. I fixed a lot of bands gear for a while and I liked to tinker around to get the best sound possible, so the name Dannysound (Danny's sound), is what he suggested… it seemed to fit with the design philosophy, plus I had no better ideas, so that’s the name.
