Muzički sekvencer

Muzički sekvencer (ili audio sekvencer ili jednostavno sekvencer) je uređaj ili aplikacioni softver koji omogućava snimanje, editovanje, ili reprodukovanje muzike, rukovanjem notama i informacijom o performansama u nekoliko oblika, obično CV/Gejt, MIDI ili Otvorena kontrola zvuka (OSC), a mogu se koristiti i audio i automatizacioni podaci za DAV i dodatke.^{[note 1]}^[1]

Moderni sekvenceri

Tipična softverska sekvencirajuća platforma iz 1980-ih, koristeći Atari Mega ST računar.

Današnji tipični softverski sekvencer, koji podržava multitrak audio () i dodatke (Stajnberg Kjubejs 6^[2])

Korisnički interfejs na Stajnberg Kjubejsu v6.0, digitalna audio radna stanica sa integrisanim softverskim sekvencerom.

Pojava digitalnog interfejsa za muzičke instrumente^[3]^[4] (MIDI) i kućnog računara Atari ST 1980-ih je programerima pružila mogućnost da dizajniraju softver koji bi mogao lakše da snimi i reprodukuje sekvence nota koje muzičar svira ili programira. Ovaj softver je takođe poboljšao kvalitet ranijih sekvencera koji su imali sklonost proizvođenja mehaničkog zvuka i mogli su samo da reprodukuju note sa potpuno jednakim trajanjem. Softverski zasnovani sekvenceri omogućili su muzičarima da programiraju predstave koje su bile izražajnije i humanije. Ovi novi sekvenceri takođe se mogu koristiti za kontrolu eksternih sintesajzera, posebno zvučnih modula koji su ugrađeni u stalak, a više nije bilo potrebno da svaki sintesajzer ima svoju namensku tastaturu.

Kako je tehnologija sazrevala, sekvenceri su stekli više funkcija, poput mogućnosti snimanja višestrukih audio zapisa. Sekvenceri koji se koriste za snimanje zvuka nazivaju se digitalnim audio radnim stanicama (engl. ).

Mnogi savremeni sekvenceri mogu se koristiti za kontrolu virtuelnih instrumenata koji su implementirani kao softverski dodaci. To omogućava muzičarima da zamene skupe i nezgrapne samostalne sintisajzere njihovim softverskim ekvivalentima.

Danas se za opisivanje softvera često koristi termin „sekvencer”. Međutim, hardverski sekvenceri još uvek postoje. Klavijature imaju sopstvene ugrađene MIDI sekvencere. Dram mašine i neki stariji sintetizatori imaju ugrađen sopstveni stepeni sekvencer. Još uvek postoje samostalni hardverski MIDI sekvenceri, iako je tržišna potražnja za njima u velikoj meri smanjena zbog većeg skupa funkcija njihovih softverskih ekvivalenata.

Tipovi muzičkih sekvencera

Muzički sekvenceri se mogu kategorizovati prema tipovima podataka, kao što su:

MIDI podaci za MIDI sekvencere (primenjeni kao hardver ili softver)^[5]
Podaci CV/Gate za analogne sekvencere^[6] i eventualno druge (preko CV/Gate interfejsa)
Podaci o automatizaciji za automatizaciju mešanja u DAW-ovima,^{[note 2]}^[7] i dodaci za softverski efekat / instrument za DAW sa funkcijama sekvenciranja
Audio podaci u audio sekvencerima^[8]

On WhatIs.com of TechTarget (whatis.techtarget.com), an author seems to define a term "Sequencer" as an abbreviation of "MIDI sequencer".
- Margaret Rouse (april 2005). „Define sequencer”. WhatIs.com (whatis.techtarget.com). TechTarget. Архивирано из оригинала 27. 6. 2015. г. „In digital audio recording, a sequencer is a program in a computer or stand-alone keyboard unit that puts together a sound sequence from a series (or sequence) of Musical Instrument Digital Interface ( MIDI ) events (operations). The MIDI sequencer allows the user to record and edit a musical performance without using an audio-based input source. ...”

Automation parameters in DAWs are often interoperable with MIDI messages, i.e. Control Changes (CC) or System Exclusive (SysEx); in that case, it can be controlled in real-time via pre-assigned MIDI messages generated by MIDI controllers or MIDI sequencers, etc. And even more so, in several DAWs, automation parameters are explicitly recorded as MIDI messages on their embedded MIDI sequencers.
