Yuav ua li cas xaiv ib tug synthesizer?

Lub tshuab hluav taws xob, tsis zoo li cov keyboard uas yuav zoo sib xws, yog cov cuab yeej tshwj xeeb hauv qhov muaj peev xwm ntawm kev ua haujlwm tshiab, cov suab sib txawv tshwj xeeb, lossis tsim lub suab raws li cov timbre ntawm cov cuab yeej acoustic (xws li violin, trumpet, piano), nrog rau qhov ua tau. ntawm kev hloov kho nws. Muaj ntau ntau hom synthesizers uas txawv ntawm cov qauv tsim, khoom siv, thiab cov khoom siv hluavtaws.

Vim yog tus tsim, peb tuaj yeem paub qhov sib txawv synthesizers nrog cov keyboard, suab modules tsis muaj keyboard, software synthesizers thiab tsis tshua siv modular synthesizers.

Keyboard synthesizers tsis tas yuav qhia rau leej twg. Lub suab modules tsuas yog synthesizers uas tau ua si nrog cov keyboard sib txuas, sib txuas lossis khoos phis tawj.

Software yog cov kev pabcuam standalone thiab VST plug-ins siv rau hauv lub computer nrog lub suab sib txuas tsim nyog (tus qauv suab phaib yog qhov kawg playable, tab sis lub suab zoo thiab qeeb ua rau lawv tsis tsim nyog los ntawm kev siv). Modular synthesizers yog ib pawg kab txawv ntawm synthesizers, tsis tshua siv niaj hnub no. Lawv lub hom phiaj yog tsim kom muaj kev sib txuas ntawm cov khoom sib txuas, kom nws muaj peev xwm tsim tau ntau yam synthesizers, txawm tias thaum ua haujlwm theem.

Vim yog hom synthesis, ob pawg hauv paus yuav tsum tau paub qhov txawv: digital thiab analog synthesizers.

Digital lossis analog? Feem ntau ntawm cov synthesizers muaj niaj hnub no yog cov synthesizers uas siv Sample-based synthesis (PCM). Lawv muaj nyob rau hauv ntau tus nqi thiab yog universal heev. Sample-based synthesis txhais tau hais tias lub tshuab hluav taws xob tsim lub suab siv lub suab uas cim tau los ntawm lwm lub cuab yeej, xws li acoustic lossis hluav taws xob. Qhov zoo ntawm lub suab nyob ntawm qhov zoo ntawm cov qauv, lawv qhov loj me, qhov ntau thiab lub peev xwm ntawm lub suab cav uas ua haujlwm zoo dua, sib xyaw thiab ua cov qauv no raws li xav tau. Tam sim no, ua tsaug rau lub cim xeeb loj thiab kev suav lub zog ntawm digital circuits, cov khoom siv hluav taws xob ntawm hom no tuaj yeem tsim lub suab zoo heev, thiab tus nqi tseem pheej yig cuam tshuam nrog lawv lub peev xwm. Qhov kom zoo dua ntawm cov qauv raws li synthesizers yog lub peev xwm rau kev ncaj ncees xyaum lub suab ntawm acoustic instruments.

Qhov thib ob nrov hom digital synthesizer yog hu ua virtual-analog (tseem hu ua analog-modeling synthesizer). Lub npe yuav zoo li tsis meej pem raws li qhov no yog digital synthesizer simulating analog synthesizer. Xws li lub tshuab hluav taws xob tsis muaj cov qauv PCM, yog li nws tsis tuaj yeem ntseeg siab ua cov twj paj nruag acoustic, tab sis nws yog ib qho cuab yeej muaj zog rau tsim cov suab nrov synthesizer. Piv rau nws cov qauv piv txwv, nws tsis tas yuav muaj kev sib tw, thiab ua ke nrog lub khoos phis tawj nws tso cai rau koj thauj khoom presets tsim los ntawm lwm tus neeg siv (kev teeb tsa suab tshwj xeeb). Lawv kuj muaj ntau dua polyphony, muaj nuj nqi multitimbral (lub peev xwm los ua si ntau tshaj li ib lub sij hawm) thiab feem ntau muaj kev hloov pauv ntau dua. Nyob rau hauv luv luv, lawv yog ntau ntau yam.

Thaum txiav txim siab ntawm virtual-analog synthesizer, txawm li cas los xij, koj yuav tsum nco ntsoov tias, txawm tias tus nqi ntawm qee tus qauv yuav poob qis dua PLN XNUMX. lawv tsis tas yuav lav zoo lub suab zoo, txawm hais tias feem ntau ntawm cov qauv muaj muaj muaj txiaj ntsig zoo rau cov nyiaj thiab txawv me ntsis hauv qhov xwm txheej, ntau yam muaj peev xwm lossis kev tswj hwm txoj kev. Piv txwv li, lub synthesizer zoo heev, nws tuaj yeem pheej yig dua vim yog lub vaj huam sib luag truncated, thiab kev siv tag nrho ntawm nws cov haujlwm yuav tsum tau siv lub computer interface, thiab lwm yam zoo sib xws synthesizer yuav kim dua, precisely vim muaj ntau lub zog tuaj yeem tswj tau. ncaj qha nrog cov pob qhov rooj thiab cov nyees khawm nyob ntawm lub tsev. Tseem muaj cov synthesizers nruab nrog ob qho tib si ntawm cov tshuab synthesis hais saum toj no, piv txwv li lawv yog virtual-analog thiab PCM synthesizers tib lub sijhawm.

Tau teev qhov zoo ntawm virtual-analog synthesizers, ib qho kev xav; rau leej twg classic analog synthesizers? Tseeb tiag, tiag tiag analog synthesizers tsis tshua muaj ntau yam thiab nyuaj rau siv. Txawm li cas los xij, ntau tus kws ntaus nkauj txaus siab rau lawv rau lawv lub suab tsis yooj yim. Tau lees paub, muaj ntau yam qauv-raws li thiab virtual analog synthesizers rau lub suab zoo meej. Analog synthesizers, txawm li cas los xij, muaj ib tus neeg ntau dua thiab tsis muaj suab nrov, uas tshwm sim los ntawm kev ua haujlwm tsis ruaj khov ntawm cov khoom, kev hloov pauv voltage, kev hloov pauv hauv kev ua haujlwm kub. Cov no yog, hauv kev nkag siab, cov twj paj nruag audiophile, lossis qee qhov kev nco txog ntawm acoustic pianos - lawv distort, hnov ​​​​mob rau cov xwm txheej hauv qhov chaw uas lawv ua si thiab tsis tuaj yeem ua txuj ua lwm yam cuab yeej. Tab sis thaum lawv muaj lawv cov zoo tshaj plaws digital counterparts, lawv tseem muaj qee yam tsis yooj yim rau cov thev naus laus zis digital. Ntxiv rau qhov loj me me analog synthesizers, me me roj teeb-powered analog synthesizers kuj muaj nyob rau hauv khw. Lawv lub peev xwm kuj me me, lawv pheej yig, thiab txawm tias lawv cov khoom ua si loj, lawv tuaj yeem muab cov suab analog zoo.

Ib qho ntxiv ntawm digital synthesis yuav tsum tau hais, uas yog Syntezie FM (Frequency Modulation Synthesis). Hom synthesis no feem ntau siv nyob rau hauv lub 80s nyob rau hauv cov synthesizers ntawm lub sij hawm, thiab tau maj mam hloov los ntawm cov qauv raws li synthesizers. Txawm li cas los xij, vim lawv lub suab sib txawv, qee cov qauv synthesizer kom deb li deb tau nruab nrog hom kev sib txuas no, feem ntau ntxiv rau qhov yooj yim virtual-analog lossis qauv-raws li lub cav.

Tej zaum nws tag nrho cov suab nyuaj heev, tab sis muaj cov kev paub yooj yim no, koj tuaj yeem yooj yim pib paub nrog cov qauv tshwj xeeb ntawm synthesizers. Txhawm rau nrhiav qhov zoo, xav tau qee cov ntaub ntawv ntxiv.

Dab tsi yog workstation synthesizer Ntawm cov synthesizers, peb kuj tuaj yeem pom cov cuab yeej categorized li Workstation. Xws li ib tug synthesizer, ntxiv rau tsim cov timbres, muaj ib tug xov tooj ntawm lwm yam functions uas tso cai rau koj los tsim thiab ua ib daim nrog ib tug twj paj nruag, tsis muaj kev txhawb nqa ntawm lub computer los yog lwm yam khoom siv sab nraud, tab sis feem ntau tso cai rau koj los tswj ib qho ntxiv, cais. synthesizer. Cov chaw ua haujlwm niaj hnub no muaj ntau lub luag haujlwm uas tsis tuaj yeem hloov pauv (thiab raws li qee qhov hais tsis zoo, cov haujlwm uas tsis siv). Txawm li cas los xij, rau koj txoj kev nkag siab, nws tsim nyog hais txog qhov tseem ceeb tshaj plaws, xws li:

• tus arpeggiator uas ua cov arpeggios los ntawm nws tus kheej, thaum tus neeg uas ua ntawv tsuas yog yuav tsum tau xaiv ib tug teev los ntawm kev tuav cia los yog nias lub yuam sij uas tsim nyog ib zaug • sequencer uas nws tus kheej ua tus xaiv suab ib ntus • ib tug ntau-track recorder uas tso cai rau koj mus khaws tag nrho cov nkauj. nyob rau hauv lub ntsuas lub cim xeeb, raws li MIDI raws tu qauv, los yog nyob rau hauv tej rooj plaub raws li ib tug suab ntaub ntawv. • Muaj peev xwm sib txuas rau lwm yam cuab yeej, kev tswj hwm, kev sib txuas lus nrog lub computer (qee zaum los ntawm kev sib koom ua ke nrog ib qho kev sib xyaw tshwj xeeb), hloov cov ntaub ntawv suab thiab khaws suab paj nruag los ntawm kev cia khoom xws li SD phaib, thiab lwm yam.

Summation Lub synthesizer yog ib qho cuab yeej tshwj xeeb hauv kev muab ntau yam thiab feem ntau tshwj xeeb suab xim. Cov qauv-raws li digital synthesizers yog ntau yam thiab ntau yam. Lawv tuaj yeem xyaum cov twj paj nruag acoustic thiab yuav ua pov thawj lawv tus kheej hauv kev txhawb nqa suab rau ib pab pawg ua si zoo li txhua hom suab paj nruag.

Virtual-analog synthesizers yog digital synthesizers tshwj xeeb hauv kev xa cov suab hluavtaws, thiab lawv muaj ntau yam. Lawv yog cov zoo meej rau cov neeg tsom mus rau cov hom phiaj ntawm cov suab hluav taws xob. Tsoos analog synthesizers yog cov cuab yeej tshwj xeeb rau cov neeg siv suab hauv hluav taws xob uas muaj peev xwm lees txais qee yam kev txwv xws li tsis tshua muaj polyphony thiab xav tau kev kho kom zoo.

Ntxiv rau cov synthesizers tsis tu ncua, nrog lossis tsis muaj cov keyboards, muaj cov chaw ua haujlwm uas muaj peev xwm tsim tau ntau lub suab tib lub sijhawm, tswj hwm lwm cov khoom siv hluav taws xob, ntau yam khoom siv txhawb nqa kev ua tau zoo thiab cov suab paj nruag, thiab tso cai rau koj sau thiab khaws cov nkauj tiav. tsis siv computer.
