6. Sequencers EE2F2 - Music Technology

Slide 2

Introduction Last time: MIDI – How electronic instruments converse with each other MIDI Messages – How to play a synthesizer by remote control Today: Sequencing – Automatically playing a tune or drum design MIDI and PCs – Sequencing utilizing MIDI The Virtual Studio

Slide 3

Early Analog Sequencers Inputs are transmitted successively Three separate channels (e.g. drums)

Slide 4

A Virtual Analog Sequencer Functionally, this straightforward sequencer is fundamentally the same as an old simple drum machine rhythms are chosen/evacuated utilizing the mouse Drum packs of expanding many-sided quality can be chosen You will, ideally, find the upsides and downsides of this style of sequencer

Slide 5

Modern Computerized Sequencing what might as well be called a control voltage or trigger flag is a MIDI message A PC can be set-up to transmit pre-modified MIDI messages at set times The grouping can be either pre-customized or recorded live from a MIDI controller (e.g. a console) Using the MIDI channels, up to 16 instruments can be autonomously controlled thusly by a solitary PC with a solitary MIDI yield

Slide 6

Advantages Over Tape Recording MIDI messages are digitally put away, culminate propagation/duplication is understood Much lower transfer speed; document sizes can associate with 1000 times littler Virtually boundless number of tracks (albeit just 16 instruments for every MIDI Out can be controlled freely) Editing offices Tracks can be replicated, circled and so on. Slip-ups can be revised Dud notes can be eradicated Timing can be made predictable (quantised) Completely new groupings can be customized

Slide 7

A Primitive MIDI Sequencer MIDI occasions (i.e. a MIDI message in addition to a period stamp) are inputted straightforwardly Useful for examining how MIDI functions and what diverse messages do. Not useful for really making music!

Examples

Slide 9

Standard MIDI Files To start with, each sequencing bundle utilized its own particular record design Swapping documents was troublesome if not unimaginable Standard MIDI documents (.MID records) are basically a concurred arrange that all sequencers are fit for trading and bringing in documents in They are what might as well be called an ASCII content document – the data's all there however a portion of the organizing comforts might be lost.

Slide 10

Digital Audio Features Computers with sound yields can transmit MIDI data and play back examples (e.g. .WAV documents) in the meantime In early sequencers, tests must be stacked into memory on the off chance that you needed to incorporate them in a tune Now, hard circles are sufficiently quick to play tests specifically from the plate In certainty a few specimens of discretionary length can be played and blended all the while… … transforming the PC into a multi-track hard circle recorder and blender

Slide 11

Virtual Studio Technology Simple illustration – the PC transmits two sorts of information on the double: MIDI succession to the advanced piano Digital sound example coordinate from hard plate Computer Mixer Audio In Audio Out Digital Audio Track Microphone Audio Out MIDI In MIDI Sequence MIDI Out MIDI In Audio Out MIDI Out

Slide 12

Virtual Instruments Actually, the computerized piano is only a DSP running some product If the PC can adapt, why not run a similar programming on the PC rather Advantages Much less expensive – spare the cost of a computerized piano Easier to program – electronic instruments frequently have a modest LCD window, PC has a pleasant shading screen and a mouse and so forth. Less commotion – advanced yield is understood Can be digitally blended (included) to the sound track so we needn't bother with a blender any longer

Slide 13

Virtual Mixing & Effects If every one of the instruments are virtual and all the sound tracks are on the hard plate, you needn't bother with a blender – the PC can do it Also, the PC can without much of a stretch mimic: EQ – simply like a genuine work area Panning, blurring and so forth. Impacts – numerous impacts like resonation are generally done digitally at any rate indeed, the main genuine (non-virtual) bit of studio gear required is the receiver (and the vocalist!)

Examples

Slide 15

Summary Most advanced recording studios are getting to be PC based Even an unassumingly determined PC can: Digitally record and play various tracks Handle MIDI sequencing Simulate different virtual instruments continuously Digitally blend and apply virtual impacts Master the entire thing into a MP3 and email it straight to the record organization!
