Trouble-shooting |
|---|
Dear Visitors
Well I'm going back to the day job world for the next 6 months. So... I won't be able to answer as many
trouble shooting questions
as I have been so please avail yourself of the online forums and blogs in which so many cool folks have shared their
MFOS project building experiences. Feel free to send questions but I may only be able to answer the ones that I know
I have not previously addressed on the site somewhere. If you don't get a reply please look over the site material
more closely as your question may well be answered already.
Read over any project you intend to build to make sure it is presented clearly enough for you to build it
and trouble-shoot it yourself (or with local help). Breadboard it and experiment.
Here are some good circuit trouble-shooting tips.
Good learning & building

MFOS uses DIP |
|---|
Make sure you order DIP package chips for MFOS boards.
No offense SOP packages but gentlemen prefer chips with longer legs.
DIP Spec. vs.
SOP Spec.
They actually make adapters.
|
Do MFOS circuits
work at +/-15V? |
|---|
All of my circuits will work with +/- 15 volts and in all probability,
with no 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 anymore (when the input is at ground).
For any circuit to which you want to apply higher voltage
examine the schematic and you'll find its not difficult to reduce the
output voltage to what you want. If it absolutely, positively has to be there with
a different supply voltage; breadboard it, apply the voltage you want, and tweak as necessary.

Welcome To MFOS, Your Synth-DIY Headquarters.
What is synth-DIY?
Synth-DIY is just what the name implies. Synthesizer Do It Yourself. Many people, like me,
grew up in the dawn of the analog synthesizer age (Moog, ARP, Oberheim, Buchla, RCA, EMu, Fairlight, PAIA and many others) and although
we may have really wanted our very own analog synthesizer with dozens of knobs and switches they were
w-a-a-a-y out of our reach financially. Now many people with a modicum of electronic skills and
a renewed interest in analog synthesizers are discovering that with a schematic, a PC board and some
electronic components they can do it themselves!.
MFOS' mission is to help people realize their synthesizer dreams.
We do this by providing analog synthesizer projects with complete schematics,
assembly drawings and professionally manufactured PC boards.
If you already have electronic skills... welcome!
If you would like to learn more about electronics or analog synthesizers then try these links:
How can I start learning about electronics?,
Analog Synth 101 and/or
The MFOS Book Store.
It's never to late to develop a new skill, reignite an old passion or exercise your creativity.
Keep imagining, keep inventing, stay ingenious.

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.

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.

The fine print... This website assumes a basic level of
electronics proficiency and knowledge. To build the projects found here you must be able
to read and understand schematics, relate schematics to physical components, solder, do
panel wiring, case building, and trouble-shooting. None of these projects has step by step
instructions to follow. There are; schematics, circuit descriptions, pc board layouts,
suggested panel layouts, and suggested modifications. Please read over any project's information
in its entirety before attempting to build it to make sure there is sufficient information for
you to succeed. If you are interested in electronics or are just getting started in
electronics check out this page for some ideas to help you get going:

When using the custom wire-wound tempcos (PT146 or PT094) from MFOS I usually
put a 100pF cap across it in the voltage summer. It seems to calm down any inductance
added by the tempco's winding. As usual if you don't have any problems leave it alone. RJW
