49 Easy Electronic Projects for Transconductance and Norton Op Amps, Delton T. Horn

TAB, 1990, ISBN 0830674551, 216 pages

This book is spoilt by one thing - mistakes, and there are lots of them, some of which are glaringly obvious, others are likely to be less so. This is a shame, as decent quantities of material on transconductance and Norton amps is hard to come by. Slightly more than the first half of the book covers OTAs, with practical circuits couched around the CA3080 and the LM13600. There are many standard circuits of potential interest to the DIY synthesist: VCAs, sample-and-holds, ring mods, VCOs and VCFs. The latter part of the book covers Norton amps, and is based around the LM3900 - there are probably slightly fewer circuits of interest here though. Those less-well equipped to spot the errors (i.e. beginners) probably ought to steer clear of this one.

Advanced Projects for the Electric Guitar, J. Chatwin

Bernard Babani, 1996, ISBN 0859343804, 'BP380', 87 pages.

Typical Babani pocket-book. Whilst primarily aimed at the guitarist (wah wah, distortion, tremelo etc.), there are comprehensive treatments of two delay cicuits in here: an analogue BBD one (MN3102/MN3207); and a digital one (HT8955).

An Analog Synthesizer for the 21st Century, Thomas Henry

Magic Smoke Electronics, 2006, v+32 pages

Another small booklet by Thomas Henry. This is a collection of schematics to build a complete simple synthesizer, containing two VCOs, a VCF and VCA, LFO etc. Be warned however it is literally the schematics and parts lists - there are no descriptions of the circuits, nor how to set them up etc., and hence should be considered only suitable for the seasoned synth DIYer, and so is clearly NOT aimed at beginners!

Build a Better Music Synthesizer, Thomas Henry

Tab Books, 1987, ISBN 0830602550, vii+167 pages

A proper hardbound book by Thomas Henry. Perhaps understandably there is some commonality with the information in this book and many other of Thomas Henry's smaller booklets. The book explains how to put together a complete snythesizer, including things like the PSU and the case. It contains circuits for most usual synth components, VCO, VCA, VCF etc., but unfortunately is a little dated in that many of them are based around hard-to-get chips, like the CEM3330, CEM3340, SSM2056, SN76477 etc. There is also an introductory chapter on what a synthesizer is and what the major components of one are.

Electronic Drum Cookbook, Thomas Henry

Originally Midwest Analog Products, 2002, v+50 pages; now available from Magic Smoke Electronics

This booklet from Thomas Henry is about twice the size of the smaller ones. It contains a lot of basic information about how to synthesize drums, and as well as several filters/tone generation circuits, it also includes a simple VCA, PSU, white noise generator, percussive-type envelope generator, and even how to build a simple drum pad using conductive foam.

Electronic Musical Instruments, Norman Crowhurst

Foulsham-Tab, 1975, ISBN 0704201445, viii+188 pages.

This book explains in fairly general terms what electronic musical instruments are and do, but does cover some technical aspects of how traditional instruments make their sound, and how synthesizers replicate these. Most of the circuits given are more 'representative' rather than practical, and only a few have sufficient component values given so that they might actually work if constructed.

Electronic Music and Creative Tape Recording, M.K. Berry

Bernard Babani, 1978, ISBN 0900162724, 'BP51', 87 pages.

Typical Babani pocket-book. About half this book is about recording on tape, and splicing etc. to manipulate the sound, but there are also lots of very simple circuits of a VCO, VCA (MC3340), and other effects like fuzz etc. One of the more complicated circuits seems quite out of place, a diode ladder filter - this book is the source of the circuit found in several places on the net: Modulus newsletter and The Free Information Society

Electronic Music Circuit Guidebook, Brice Ward

TAB Books, 1975, ISBN 0830657436, 222 pages.

In the preface the author states he wrote the book because at the time he couldn't find other books with details of synth circuits in them. There are quite a lot of circuits in here, covering a variety of oscillators, filters, a 'function generator', VCAs, etc., and there are also circuits less often covered, like a spring reverb, ring modulator, envelope follower etc.

Electronic Music Circuits, Barry Klein

Originally published by Howard Sams, 1982, 302 pages. Now available direct from the author, Electronic Music Circuits in a comb-bound form, updated in 1996.

This is probably one of the better books explaining synthesizer circuits in some detail, covering not only oscillators, filters, envelope generators, voltage-controlled amplifiers etc., but also things like the PSU and keyboard controllers. Though some of the circuits are based around now-obsolete CEM and SSM synthesizer chips, there is much to be learned from this book. It also contains quite a lot of circuits taken from Electronotes, q.v. (And if you intend to get serious about all this stuff and are contemplating buying a copy of this book, getting a copy of the Electronic Music IC Databook at the same time is thoroughly recommended!)

Electronic Music Circuits: The Reprints Vol 1, Thomas Henry

Midwest Analog Products, 2002, 162 pages.

This is a larger comb-bound book from Thomas Henry, and consists of reprints of 38 articles from old newsletters of the 70s and 80s, such as Electronotes, Polyphony and Electronic Musician. It has circuits of many components familiar in synths, e.g. VCOs, VCAs, VCFs, envelope generators, and also less usual ones like BBD delays, drum circuits etc. (It is not believed that a 'Volume 2' has ever been produced.)

Electronic Music IC Databook, Barry Klein

Published by the author, Barry Klein, along with Electronic Music Circuits (if you are serious about this stuff and are buying that book, buy this one too!).

This is a large (more than 300 pages) compendium of datasheets of old (generally) synthesizer-dedicated ICs. Some of the information is available online, most notably Synthesis Technology's CEM chip page, but for many of the chips, this is likely to be the only place you will find the data.

Chips covered are: CEM: 3310, 3312, 3320, 3328, 3330/3335, 3340/3345, 3350, 3360, 3371, 3372, 3374, 3378/3379, 3387, 3389, 3391, 3394, 3396, PA381/382 (CEM3381/2), PD508, SAM8905. SSM: 2000, 2010, 2011, 2012, 2013, 2014, 2015, 2017, 2018, 2020, 2022, 2024, 2030, 2033, 2038, 2040, 2044, 2045, 2047, 2050, 2055, 2056, 2100, 2110, 2120/22, 2125, 2134, 2200, 2210, 2220, 2300, 2402/12

The Electronic Musical Instrument Manual, A. Douglas

Tab Books, 1976, ISBN 0830658327, 205 pages

The preface warns that 'this is not a constructional book', and indeed it is not; it is also subtitled 'A comprehensive guidebook on the theory and design of electronic musical instruments, with special emphasis on the organ'. Thus it is not about synthesizers per se, but there are many circuits of oscillators, tone controls, noise generators and vibrato circuits etc., and seemingly a large number from actual commercial organs, and many of these employ all manner of electro-mechanical devices (motors driving toothed wheels), photo-electric devices (slotted discs etc.), and other such curiosities (with many older circuits using valves as well as more 'modern' ones using transistors!). Potentially useful if you are trying to find out how some old organ achieved some particular effect or other.

Electronic Music Learning Projects, R. Bebbington

Bernard Babani, 1993, ISBN 0859343294, 'BP329', 114 pages.

Typical Babani pocket-book. The circuits in here are at a very introductory (e.g. schoolboy) level. They include several oscillator circuits (including a very Stylophone-like one), and others like a metronome etc. It is clearly not intended as a book of serious synthesizer circuits, though doubtless one or two could be adapted for such.

Electronic Music Projects, R.A. Penfold

Bernard Babani, 1980, ISBN 0900162945, 'BP74', 106 pages

Typical Babani pocket-book. The circuits in this book are mostly fairly simple, and many are aimed at the guitarist: wah wah, fuzz, sustain etc.; there is actually a circuit for a spring reverb unit (though there doesn't appear to be anything like a specification for the spring tank itself); a Stylophone-like 'Stylus Organ'; the most synth-like circuit is a 555-based oscillator, but it isn't voltage-controlled.

Electronic Projects in Music, A.J. Flind

Newnes, 1979, ISBN 040800391X, 81 pages.

(Similar in size and type to the Babani books, but better print quality.) Contains details for building quite a few simple circuits, such as waa-waa, fuzz, a couple of pre-amps etc. Probably the most complex circuit is for a Stylophone-type mini-organ.

Electronic Synthesiser Construction, R.A. Penfold

Bernard Babani, 1986, ISBN 0859341593, 'BP185', 99 pages.

Typical Babani pocket-book (note the non-conventional spelling in the title). It contains details for making a basic synthesizer with the usual VCO-VCA-VCF voice, including an ADSR envelope generator, and several simple sequencer circuits. There is also a pseudo-stereo circuit using a simple phase-shift circuit.

Electronic Synthesiser Projects, M.K. Berry

Bernard Babani, 1981, ISBN 0859340562, 'BP81', 81 pages.

Typical Babani pocket-book (note the non-conventional spelling in the title). It contains details for a basic synth, but again uses some now hard-to-get chips, namely the SN76477 'single chip synth' and a TDA1022 BBD delay. Other circuits include a 4017-based sequencer, 8038 and 555 VCOs, and a logic-based ADSR.

Electronotes, ed. Bernie Hutchins

Electronotes is a newsletter-like publication produced by Bernie Hutchins, covering technical details of music synthesis and sound processing: back-issues up to the very first issue in 1972 are available, and the complete set is a rich repository of circuits, techniques and ideas. The 'everything' package is a huge amount of information - it comb-binds into about 30 useful-sized volumes, and occupies over 18 inches of shelf space! For those not wanting to go to the expense of getting everything, the Musical Engineer's Handbook and the Builder's Guide and Preferred Circuits Collection is a good compromise. There is a fairly simple index of Electronotes here, which may give an indication of the totality of subjects covered. (The index covers up to August 2003.)

IC LM3900 Projects, H. Kybett

Bernard Babani, 1978, ISBN 0900162732, 'BP50', 119 pages.

Typical Babani pocket-book. Many older synthesizer circuits made use of the LM3900 chip, which is slightly harder to figure than an op amp. Finding books that even mention this chip is hard, never mind one dedicated to it. This is a nice, tractable introduction to the chip, what it is and what it does, and contains dozens of simple utilitarian circuits.

IC Op-Amp Cookbook, Walter G. Jung

3rd edn: Prentice Hall, 1997, ISBN 0138896011, xviii+581 pages.

1st edn: Sams, 1977, ISBN 0672209691, 591 pages.

This book is frequently recommended as a good reference for op amps. Part 1 starts with the basic principles of ideal op amps, and then goes on to catalogue many of the non-idealities of real op amps, how they affect a circuit's operation, and how to deal with them. Part 2 is a large selection of application circuits, covering many of the standard op amp circuits seen in practice, both linear and non-linear. (Notably there is nothing about active filters in the book though.)

The first edition of the book is also worth checking out, as there is some material which is not present in later editions which may be of interest for synth DIY readers: chapter 6 (approx. 90 pages) covers op amp use in audio circuits (mainly amplifiers and pre-amplifiers etc., but also a small section on active filters); chapter 8 (approx. 100 pages) covers progammable op amps, including operational transconductance amplifiers (OTAs) such as the CA3080, and also current differencing amplifiers, such as the LM3900, both of which find wide application within synthesizer circuits.

(The Prentice Hall third edition appears to be little more than a photocopy of the Sams book, and some readers have noted that the print quality is not so good in some places in the book.)

Making Music with the 3080 OTA, Thomas Henry

Originally Midwest Analog Products, 2003, vi+26 pages; now available from Magic Smoke Electronics

Another small booklet by Thomas Henry. This one contains an easily-digestable introduction to the CA3080 Operational Transconductance Amplifier, including circuits for a simple VCA, VCO and a ring modulator.

Making Music with the 566, Thomas Henry

Originally Midwest Analog Products, 2003, vi+26 pages; now available from Magic Smoke Electronics

Another small booklet by Thomas Henry. This one has lots of circuits and detail around the 566, a 'function generator'-type chip (which unfortunately was made obsolete ages ago I suspect). The booklet shows how to hook one up as a VCO which gives all the major waveforms, sine, tri, ramp, square etc., and also others like a noise circuit.

Making Music with the NE570 Compander, Thomas Henry

Originally Midwest Analog Products, 1998, viii+19 pages; now available from Magic Smoke Electronics

Another small booklet by Thomas Henry. This one shows how to use the NE570 chip not only as a compressor/expander, but includes other circuits such as an envelope follower and a VCA.

More Advanced Electronic Music Projects, R.A. Penfold

Bernard Babani, 1986, ISBN 0859341488, 'BP174', 78 pages.

Typical Babani pocket-book. This contains slightly more advanced/complex circuits than its predecessor, Electronic Music Projects, BP74 (q.v). Amongst the circuits here: a simple phase shifter; BBD-based flanger/chorus/vibrato unit; a ring modulator; and the latter part of the book details a 'percussion synthesizer', though this doesn't appear to use the more traditional method of 'pinging' a resonant filter, so heaven knows what it would actually sound like... Many of the circuits make use of the now obsolete LM13600 OTA, and so presumably would need some small adjustments to use the LM13700 instead.

Musical Applications of Microprocessors, Hal Chamberlin

Hayden, 1985 ISBN 0810457687, 802 pages (2nd edn)

Although primarily concerned with microprocessors and their use within sound and music synthesis, early chapters have introductory material on synthesis in general, including methods using tape, voltage control etc. There is also a nice chapter giving typical examples of basic analogue circuits such as VCOs, VCFs, VCAs etc., with good explanations of how they work.

Music Synthesizers: A Manual of Design & Construction, Delton T. Horn

TAB Books, 1984, ISBN 0830615652, viii+343 pages.

There are lots of schematics in this book, but it is assumed the reader can take the schematics and turn them into practical circuits. Many of the designs utilize some of the older synth chips: CEMs, SSMs, the MM5837 (digital noise) and the SN76477 effects chip. There is also a large section on patching ideas.

Noise Generator Cookbook, Thomas Henry

Original probably Midwest Analog Products, 2003; now available from Magic Smoke Electronics, 2009, vi+27 pages

Another small booklet by Thomas Henry. This one contains circuits for most of the basic ways to generate and filter noise, including : reverse-biased p-n junction; pseudo-random shift register sequence; multi-oscillator bank, pink noise filter, etc.

Practical Electronic Music Projects

Bernard Babani, 1994, ISBN 0859343634, 'BP363', 122 pages

Typical Babani pocket-book. There are many circuits to interest the guitarist: distortion units; a guitar tuner; pseudo echo etc. More general circuits include: a metronome; a pseudo stereo unit; mixers etc. There are also some interesting MIDI circuits, including: a MIDI comparator, which looks for a specific bit pattern; a simple MIDI tester; a MIDI controller pedal; a MIDI lead tester etc.

Small Signal Audio Design, Douglas Self

Sound Synthesis: Analog and Digital Techniques, Terence Thomas

TAB Books, ISBN 083063276X, x+166 pages.

Contains circuits and details for building a complete synthesizer, from the PSU, through VCO, VCA, VCF etc., and including a simple sequencer, though some of the circuits are perhaps a little unorthodox. There's also a strange circuit that produces trigger pulses from MIDI data, with scant regard for what the data actually is.

Troubleshooting and Repairing Electronic Music Synthesizers, Delton T. Horn

TAB, 1992, ISBN 0830639217, x+206 pages.

This is a very odd kind of book, which probably has a very narrow readership. There are very few schematics in here, yet it is trying to help people to troubleshoot synthesizer-based circuits. After a basic introductory chapter on what a synthesizer is, there is a chapter of general troubleshooting techniques, which mostly looks like good, sound advice. Then there are five chapters entitled 'Problems with XXX', where 'XXX' = VCOs, VCAs, VCFs, etc. There are also chapters on digital synths, software and hardware problems, and MIDI. At the back are three schematics: an SCR-based VCO; a FET-controlled multi-feedback single op amp VCF; and a VCA circuit using three transistors and an op amp, and running off 9V and 18V supplies (which looks like it might owe something to a Korg circuit) - none of these look anything like 'standard' synth circuits!

VCO Chip Cookbook

SMS Electronics, 2007, vi+118 pages. According to this electro-music.com thread (pay attention to the dates!), it looks as though Magic Smoke/Lulu will make this book available again at sometime in the future.

A larger-than-usual offering from Thomas Henry. It includes detail on how to use three VCO chips: the 566, 8038 and XR-2206. Some of the information is taken from Making Music with the 566 (q.v.), but there is much more here besides, including exponential conversion, triangle-to-sine waveshaping etc.
