    Make: Analog Synthesizers is now available for sale!
     
    I finally wrote a book about Synth-DIY and analog synthesizers in general. I'm betting that this book will answer a lot of your questions regarding synth-diy, tools for your shop, soldering tips, trouble shooting advice, and a lot about using chips I consider to be essential to synth-diy. The explanations about op-amps, negative feedback and integrators may finally clear a few things up for you about those black boxes. There are two chapters on the NOISE TOASTER (making one and how it works). When all is said and done you can move on to recording projects using your gear and Audacity. You can't put everything into one book but I really tried to put something for everyone into this one. Make: Analog Synthesizers is available at these fine book sellers:
     
     
    Build the Sound Lab Mini-Synth Mark II Analog Synthesizer
    If you've been wanting to build a small but capable synthesizer this is the project for you. The Sound Lab Mark II will surprise you with its array of sound shaping modules. I invite you to check out the sound samples below which were made with the Sound Lab Mark II driven via a MIDI to CV convertor. I used SONAR X1's effects for reverb but never for pitch correction. The VCOs in the Mark II track very well as does the VCF when in oscillation after thorough calibration. Here are some YouTubes which present the features of the unit as well as sound samples.

    Mark II - Sound Sample
     
     
    MFOS Stocks the harder to find components for this project which you can order at the time you order your PC board and professionally machined front panel.
     
     
    The Sound Lab Mini-Synth Mark II is small, cool, well tempered and very versatile. It will become one of your favorite analog synthesizers. Take me to the SLMS Mark II project...

    For these samples I used SONAR Producer Edition for recording, mix down, and addition of reverb. All sounds are directly from the Sound Lab Mark II driven via a MIDI to CV convertor or MFOS Single Buss Keyboard Controller (the last was recorded real time).

    NEW! - NOISE TOASTER
    The MFOS NOISE TOASTER is way more fun than you thought was possible with a 9V battery! It's an awesome little 9V powered noise box that's like carrying around a miniature synth. This project is a bit more complex than the WSG but has far more sound shaping and producing capability. This is going to be one of your favorite portable toys (amp and speaker built in). PCBs and PLATEs IN STOCK!
     
    Contribute a Composition to the Art of Electronic Sound Project
    You've put blood, sweat and tears into building your very own analog synthesizer. Show the world what it can do. Contribute a composition to "The Art of Electronic Sound" project so other creative synth-diyers can be inspired. Whether you create: traditional, twelve tone, noise, soundscapes, dreamscapes, space music or something further out, as long as it's electronic and you built some of the gear, we want to hear it. The duration of your piece can be short or long and the content simple or incredibly textured. Whether you're a newbie or someone who's been building for years submit a composition. Your composition might be the one heard by a famous filmmaker looking for an obscure electronic sound track.
     
    16 Step Sequencer Quantized Vari-Clock Module
    Quantized duration adjustment literally adds a new dimension to your MFOS 16 Step Sequencer.

    Check out our new project. It gives the MFOS 16 Step Sequencer the ability to have settable duration per step in 16 quantized increments as well as multiple gate modes. It is definitely an advanced and challenging project but I tried to document it thoroughly. Thank you for your thoughtful comments on this project.

    I think you'll really like the functionality provided by this circuit.

    The Sound Lab ULTIMATE. Our most advanced synthesizer project.
    The Sound Lab ULTIMATE packs: Three Musically Accurate VCOs, a White Noise Generator, an Active Mixer, a Voltage Controlled LP Filter, a Voltage Controlled Amplifier, an Attack Release Envelope Generator, two Low Frequency Oscillators, a Repeat Gate Generator, Sample & Hold, Attenuator Bank and Patch Panel into one totally cool synth-DIY project.

    The following songs played by Arielle Wilson on the ULTIMATE.

    Star Trek Next Generation Theme
     
    MFOS Delayed Modulation Module
    The MFOS delayed modulation module includes an Attack Release envelope generator, Low Frequency Oscillator with square and sine waveforms, and a Voltage Controlled Amplifier. These separate elements are connected in the classic delayed modulation patch such that the LFO is fed to the input of the VCA and the AR generator is connected to the VCA's control input. When you apply a gate to the circuit the AR generator is gated on and the VCA responds to the applied envelope and the LFO comes through the VCA. You use the output of the module to modulate other voltage controlled modules. Since there is a complete AR generator built into the module you have some really excellent flexibility.

    Check out the Delayed Modulation Module project

     
    The venerable Sound Lab Mini-Synth. Old school analog and still going strong.
    The Sound Lab Mini-Synth is a great project. It is a complete mini analog synth on one PC board. It has two VCOs, one LFO, one Mixer, one State Variable Low-Pass/Band-Pass Filter, one AR Envelope Generator with repeat, and one VCA. It runs off of two nine volt batteries for a long time due to its low current design. Check out the MINI-SYNTH!

    New Flexible Synth-DIY Experimenter PCB
    Synth-DIY Experimenter PCB
    This project helps creative electronics hobbyists who have successfully completed the WSG learn more about synth-diy. You make "patches" with the Sound Effects project by patching the various "modules" together, and adjusting knobs and switches.

    CLICK HERE TO GO TO THE PROJECT!

    Multi-track demonstration of sounds you can expect (reverb has been added during mixdown):
     
    SDIY Experimenter Board Opus 1 Wilson

    A *.sfz compatible soft-synth and samples of sounds made with the MFOS Synth-DIY Experimenter PCB were used to create this cool multi-track version of Tchaikovsky's "Dance of the Sugarplum Fairy".
     
    Dance of the Sugarplum Fairy Tchaikovsky
     
     
    The Synth-DIY Experimenter PCB contains some of the first synth circuits I started experimenting with when I first got into synth-diy. You don't have to build all of the modules. You can just build what you want to make a specific sound. You want wind... just build the White Noise Generator and one VCF. You want better wind build the White Noise Generator both VCFs and the output mixer. How about birds or bell sounds... just build the Sound Effect Oscillators an AR Envelope Generator and an LFO. You can go as far as you like with this project.

    This project will NOT result in a 1V/octave Moog like instrument but it will provide you with a lot of sound making fun. In any case it will be a fun learning experience and the finished project will keep you and anyone else within earshot very entertained.

     
    Reading really is fundamental. Have you read any good books lately?
    Do you want to become a vintage synth expert. These books will give you the knowledge to become a true analog synth guru. Growing your hair and beard long and moving to a mountain top is optional. Any would make an exceptionally thoughtful gift. See more books...

     
    The MFOS Mini-Controller. This is too cool not to have so what are you waiting for?
    The MFOS Mini-Controller

    The MFOS Mini-Controller has a twenty nine note stylus keyboard (C - C - C to E) built right into the PCB. It can be used to play your Sound Lab Mini-Synth or 1V/Oct modular. The PCB supports four CV outputs (2 with portamento 2 without portamento). There is one trigger output and one gate output. This and a Sound Lab Mini-Synth would make a great combination for your first forray into synth-diy.

     
    Will MFOS circuits work with a +/-15V power supply?
    All MFOS circuits will work with +/- 15 volts with from none to minor value changes. All of the chips I recommend are rated for the higher voltages so you should be good to go. One small consequence is that the peak voltage of things will be a bit higher. Oscillator P-to-P outputs will be higher at higher supply voltages and AR or ADSR voltage peaks will be higher also. Filters and amplifiers will have more headroom and may need a bit of re-biasing if you find that the output is not sitting at ground when the input is at ground. For any circuit to which you want to apply higher supply voltage examine the schematic and you'll find its not difficult to reduce the output voltage to what you want. Where bias levels are set with resistor dividers you may need to tweak values. If it absolutely, positively has to be there with a different supply voltage; breadboard it, apply the voltage you want, and tweak as necessary.

    Is MFOS Synth DIY For Me?
    Individuals often ask whether MFOS projects are suitable for them. The answer really lies with you. Here are some things to consider before jumping in and ordering a project PC board or kit.
    1. Have you built electronic projects before?
    2. Do you know how to solder and have a decent soldering station?
    3. Do you have electronic tools? These would include smaller more precision tools: pliers, diagonal cutters, screw drivers, etc.
    4. Do you own or have access to electronic test equipment? For example an oscilloscope, a digital volt meter, and a bipolar bench power supply.
    5. Do you have a friend or teacher that has experience building and troubleshooting electronic projects willing to help you?
    If the answer to one or more of these questions is no then you may need to gain a bit more experience before starting an MFOS project. We at MFOS want your project experience to be fun and successful but having the necessary basic knowledge and tools is important or it could turn into a frustrating or disappointing experience.

    I consider the WSG and the Envelope Follower Filter projects to be the most basic projects MFOS provides. So if you are new and have answered yes to the questions above go for it. Here is some additional info on getting started

    Whether you are on your 1st or 101st synth DIY project I hope you find MFOS projects to be interesting and enjoyable.

    Good building.
