13. Digital Vinyl
Systems
vinyl emulation
software FTW

14. Digital Vinyl System (DVS)
DVS = ([turntable|CDJ] + timecode [record|CD]) + ADC + laptop + mixer
WHERE
the ADC (analog-to-digital converter, generally a dedicated multi-channel
soundcard or USB/FireWire audio interface box thingy) takes the analog
signal from a timecode vinyl record or CD and transforms it (guess what!)
to a digital signal, so your shiny laptop/$device can cope with it;
AND
the laptop is running a piece of software whose job it is to map the signal
it gets from the ADC to the $soundfile playing, routing the retouched
music stream back to the ADC (from where it's handed over to the mixer).

15. Popular DVSs include (nlt):
Serato Scratch Live
Native Instruments Traktor Scratch Pro
Stanton FinalScratch Record
Numark Virtual Vinyl
M-Audio Torq Control Vinyl
Mixxx
Image-Line Deckadance (can be controlled with pretty
much anything, really)

30. Match-making
1, 2, 3, setlist!

31. Rhythm,
baby!
beats, bars, pulse &
patterns

32. Got Rhythm?
beat: what you'd count to (4/4)
bar/measure: in that case, a full cycle of 4 beats
pulse/meter: the logical entity of what you're hearing
pattern: a series of more or less accentuated
percussion sounds; basically, what's making music
genres distinguishable from each other

33. Measures & hypermeasures

34. What is house?
House music is a universal language, spoken and understood by all. You
see, house is a feeling, that noone can understand really unless you're deep
into the vibe of house. House is an uncontrollable desire to jack your body.
And, as I told you before, this is OUR house, and OUR house music.

37. Key is key.
from soundwaves to
the Camelot wheel

38. Harmonic mixing basics
Two tracks will be harmonically compatible if their respective keys are
found in some specific correspondence with each other. Some of these
correspondences work better to the 'Western' ear, some less.
At this point, I could explain to you as to why the frequency f = v/λ where
the wavespeed v = √T/µ and λ is one full wavecycle, and how this affects
not only sympathetic vibrations in 'real' instruments, beating, or even
wave cancellation, plus a significant difference in what we'd call nice
(harmonic) or not - OR, let's just call in a short...

39. WHITEBOARD BREAK!!!1!!1

40. Key compatibility cases
Same key/tonality (tonic)
Relative major/minor key
Dominant key (perfect V)
Sub-dominant key (perfect IV = I - V)

41. Key compatibility cases

42. The Camelot Wheel

43. The Camelot Wheel

47. The Camelot Wheel

48. The Camelot Wheel

49. The Camelot Wheel

F (rel. sub-dom)

50. The Camelot Wheel
Em (dom)
Am
Dm (sub-dom)
G (rel. dom)
C (rel. maj.)
F (rel. sub-dom)

51. Energy Boost & modulation
Go up 1 or pref. 2 semitones from your current key:
Am => Bbm resp. Bm
Reflected in the Camelot wheel, that'd be adding 7
resp. 2 to your current position:
8A => 3A resp. 10A
Mixing a major to a minor key or vice versa is also
considered a modulation mix; however, it is essential
the melody lines DO NOT clash in the mix.

52. The Camelot Wheel, again...
