Hanya mafi sauki don saita sabar Audio JACK ita ce amfani da aikace-aikacen JACK Control (wanda aka sani da Qjackctl). Ana iya ƙaddamar da wannan cikin sauƙi daga LXPanel ko Wbar Dock. Don saita katin sauti ɗinku danna maballin 'Saita'.

A cikin misalin da ke gaba tsarin yana da hadadden katin Intel HDA wanda aka zaba daga menu na 'Interface'. Gabaɗaya, idan muryar kallonku tana cikin wannan jeri saboda yana da goyan bayan ALSA da JACK. Don amfani da keɓaɓɓiyar igiyar wuta dole ne ka zaɓi 'firewire' maimakon 'alsa' a cikin menu na 'Driver'. Yana da matukar mahimmanci a tabbatar cewa 'Real Time' an zaɓi shi a cikin 'Sigogi'. Wani lambar don bincika saitin shine filin 'Periods / buffer'.

Idan kuna fuskantar 'Xruns' ko cuts ɗin odiyo kuna buƙatar haɓaka wannan lambar har sai sun ɓace. Idan kuna yin rikodin kai tsaye zuwa rikodin waƙa ƙananan lambobin latency basu da matukar buƙata, amma idan kuna yin rikodi ta hanyar plugin ko wasu aikace-aikacen odiyo da aka tura zuwa waƙar rikodin to kuna buƙatar ƙananan latencies. Don amfani da JACK tare da masu haɗawa da MIDI plugins ana ba da shawarar ƙara ƙimar 'Lokaci Kayyade (msec)' zuwa milliseconds 3000 (ko fiye) don ingantaccen kwanciyar hankali.

Yawancin aikace-aikace, da zarar an fara su kuma suna gudana a ƙarƙashin JACK, za su gudanar da haɗin haɗin su daga shirin da kuke amfani da su, kodayake wani lokacin ya zama dole a yi amfani da aikin 'Haɗa' a cikin JACK Control don haɗa aikace-aikace ko ma kayan aiki kamar maɓallan MIDI. A cikin misali mai zuwa mun haɗa abubuwan MIDI na maɓallin kewayawa 'VMPK' don sarrafa bankin sauti na Qsynth synthesizer. Taga 'Connections' tana da shafuka uku. Shafin 'Audio' yana nuna hanyoyin haɗin sauti da aka yi daga makirufo ko abubuwan layi na katin zuwa aikace-aikacen da kuke amfani da shi kuma daga aikace-aikacen zuwa abubuwan da ake amfani da su na katin sauti a yanzu. Shafin 'MIDI' don yin kayan aiki ne da haɗin software waɗanda suke amfani da 'JACK MIDI' kuma shafin ALSA ma haka yake don aikace-aikacen da suke amfani da 'ALSA MIDI'.

Ga waɗanda suka fi dacewa da hankali akwai kuma wasu hanyoyin amfani na patchbay guda biyu don yin haɗi a ƙarƙashin AV Linux: Patchbay linuxDSP JP1 da ke cikin 'JACK Plugins' menu da 'Patchage', wanda aka samo a cikin 'Audio' menu kuma aka nuna a cikin wadannan adadi.

Wasu karin bayanan

Wani abu da yake tuna min Qsynth shine cewa baya zuwa da bankin sautuna da aka ɗora ta tsoho (Ina jin za'a iya saita shi don yayi), don haka a karo na farko da bai yi sauti ba kuma wani mai amfani da malalaci ya riga ya jefa shi tawul (akwai). Kamar yadda ni kuma na kasance jahilai sosai, Qsynth manaja ne na Fluydsynth synthesizer, don haka ina tunanin akwai wata hanya da za ta ɗora banki ta hanyar tsohuwa, amma tunda ni rago ne sosai, ban samu zuwa wannan ba tukuna. Tabbatar da cewa lokacin da muke magana game da synths zan yi ƙoƙarin ba ku mafita, yayin da za ku bincika Google. Don lodin bankin sautuna cikin Qsynth, zamu je menu 'Saituna'.

A cikin shafin 'Soundfonts', za mu ɗora (maballin 'Buɗe') bankin da Av Linux ya kawo kuma yana cikin hanyar '/ usr / share / sauti / sf2 ′. A yanar gizo akwai adadi mai yawa na bankunan kyauta da zan ambata, don fita daga matsala akan shafin MuseScore akwai guda 3 masu mutunci, daga cikinsu akwai tsoffin bankin Av Linux.

Da zarar an bude bankin sauti, Qsynth zai yi maka kashedi cewa dole ne ya sake kunna injin na sauti, wanda zaka ce a a. A wannan lokacin, VMPK zai cire haɗin daga Qsynth, amma kun rigaya san yadda ake haɗa shi, dama? (Haya daga cikin alamun: Qjackctl> Window na Haɗi> Zaɓi ɗaya, zaɓi wani> Haɗa).

Yanzu zaka je VMPK ka latsa madannin kwamfutarka (ko ka latsa madannin makama)… “sanyi”, daidai? 😉
