This page will be a scrapbook for the ideas I come across. The main initial source is the Strange Bible.

As everyone knows, Allen Strange's Electronic Music Systems, Techniques and Controls is the best book on analogue synthesizing. It includes copious exercises throughout but two sections are of particular note. The chapter on control voltage sources includes two key patches, 'correlation of random voltages' and Dream Machine. and ends with a series of exercises and projects, of which I will list the relevant ones below. Then, the final chapter of the book is 'scores for analysis and performance': again I will list the ones I might use,  
Correlation of random voltages, Allen Strange
Dream Machine, Allen Strange
Allen Strange, control voltage exercises
1-3. contemplate acoustical and electronic instruments
4. experiment with linear and exponential functions
5. become aware of the voltage range used on your equipment as it is important for subsequent exercises
6. experiment with intervals on three VCOs

this is building up nicely

7. 'if you have access to integrators, quantizers and multipliers (coupled VCAs), turn discrete control voltages from keyboards, sequencers etc. into continually varying functions. A fixed voltage may also be made into a fluctuating voltage by multiplying it with a sloped voltage such as an EG, LFO, fluctuating random etc. Now reverse the process and turn varying  functions into discrete levels. Invent an instrument based on this process.'
8. experiment with  alternate tunings, starting with Robert Ehle's Prelude in 19 Tone Equal Temperament, by attenuating the voltage from a keyboard.
9. now try the Asian 7-tone equal-temperament.
10. set up alternate tunings and a method of switching between them
11. 'take a single voltage function and apply it to every controllable parameter in your instrument', repeat with two and three control voltage sources.
12. Daniel Goode's Faust Crosses..', see below
13. random access sequencing after Frank McCarty , see fig 1
14 John Cage's Williams Mix, uses shaped pieces of pre-recorded tape. Simulate the shapes with VCAs.
15. interacting tapes, a similar idea to the Apples&Pears patch below, see fig 2
16. Robert Ashley's String Quartet Describing the Motions of Large Bodies - a real string quartet making scraping noises which are processed through logic gates.
17. extracts from patch books:
a) ARP Axxe bass
b) Roland 'guns'
c) PAIA 'small dog or laughing hyena oe creeping bird or?' see fig 3, this is difficult to read.

Allen Strange, scores for analysis and performance
1. Douglas Leedy, Entropical Paradise (with Bird Call) fig 1
2. Frank McCarty,  Stochastic Arp fig 2
3. Mark Styles, Orion Rising fig 3
4, John Strawn, Akarui Tsuki fig 4
5. Dan Wyman, A Shadow of Its Former Self

although I have attached some of the diagrams for my own benefit, these only make sense in the context of the text. Buy the book.

Daniel Goode's Faust crosses the Raritan somewhere in East Africa and finds himself back home, a little south of the Reich... Now there's a title for you (as we Welsh tend to say). Essentially, the piece involves picking a tune, setting up the first few notes on the sequencer and than gradually working through the rest of the tune setting one note at a time, so the piece gradually 'wipes over' itself. He suggests Yankee Doodle on a 10-step sequencer, I'll have an 8-step to begin with and am inclined towards the last few notes of the Beethoven violin concerto. Strange says don't use a quantizer, I am inclined to have one VCO with and one without. Just waiting on Tom from Analogue Solutions to come up with the SQ8. Mr Goode has a terrific web site here and Faust is in the scores (one of the one-pagers).
The best example from Apples and Pears, I'm inclined to try it with BBC Radio 4 (speech) as the voice and Radio 3 (music, usually classical) rather than the Chopin Nocturn.

Online patchbooks (as I find them)
