Kev hloov pauv hauv cov qauv thiab ib nrab cov qauv synths tau tsim ntau yam zoo nkauj ntawm cov kev xaiv mono-synth tshiab rau suab paj nruag thiab siv suab nrov, tab sis ib qho teeb meem nrog mono-synths (thiab feem ntau Eurorack cov qauv thiab/lossis teeb liab ntws) yog qhov tsis yog yog cov tshuaj synthesizers mono phonic, lub ntsiab lus (ntxhib) lawv tsuas tuaj yeem tsim ib daim ntawv ntawm ib lub sijhawm, tab sis kuj yog mon aural, lub ntsiab lus tias ib qho kev ceeb toom synth tsim tawm tsis muaj qhov tshwj xeeb hauv thaj chaw tso suab. Tau kawg ntau lub sijhawm mono teeb liab tuaj yeem siv siv lub lauj kaub tswj ntawm lub tov khoom (lossis hauv DAW thaum kaw) tab sis muaj feem yog tias yog koj siv lub synth rig rau kev ua neej nyob (lossis tsis yog) feem ntau yuav yog qee qhov txiaj ntsig los faib lossis tso lub teeb liab hauv lub tso suab-tso suab cia, tso koj txhais tes rau lwm qhov tweaks thiab ua rau, thiab qhov no yog qhov haujlwm no yuav muab rau koj.

Nov yog qhov haujlwm theem nrab uas yuav cia koj ua li ntawd. Peb yuav xav tias koj muaj qee lub khw yooj yim, khoom siv hluav taws xob, siv cov khoom siv thiab Arduino kev paub dhau los hauv Cov Lus Qhia no.

Arduino board lossis AVR programmer sib xws

Kauj ruam 1: Program ATTiny

Rub tawm thiab unzip cov ntawv txuas ATTiny85_CV_Panner. Zip thiab tso daim nplaub tshev unzipped hauv koj phau ntawv teev npe Arduino, tom qab ntawd qhib Arduino IDE thiab thauj khoom ATTiny85_CV_Panner.ino kos duab.

Raws li tau hais yav dhau los qhov no yog qib qhia ntawv, yog li nws dhau qhov txwv kom suav nrog cov lus qhia rau thauj khoom Arduino kos duab mus rau ATTiny AVR. Yog tias koj xis nyob nrog Arduino IDE thiab tsis tau ua qhov no ua ntej, koj tuaj yeem pom cov lus qhia zoo heev ntawm MIT's HighLowTech.com. Kuv siv TinyProgrammer los sau thiab sau daim duab kos rau kuv.

Ua haujlwm cov nti siv 1 MHZ lub moos sab hauv teeb tsa rau cov qauv sib txawv uas koj siv. Kuv sim cov duab kos ntawm ob qho tib si 45 thiab 85, thiab daim duab me me yog li nws tsawg kawg ua ke rau 25 yog tias koj muaj. (Sau ntawv ceeb toom hauv cov lus yog tias koj sim nws thiab nws ua haujlwm lossis tsis ua.)

Cov duab kos no yog ib qho uas kuv pom ntawm Arduino.cc cov laug cam-Kuv tsis xav tias kuv tau hloov pauv dab tsi tab sis tus lej nkag (yog tias.) Ua tsaug rau leej twg tshaj tawm qhov ntawd!

Kauj ruam 2: Electronics

Kuv tau ob leeg tso lub Circuit Court tawm ntawm lub khob cij thiab suav nrog daim duab ntawm kuv chav nyob sab hauv. Kev tawg ntawm SparkFun ua rau txoj hauv kev yooj yim los tso lub qhov nyob hauv qhov chaw tab sis tsis tsim nyog tiag li koj tuaj yeem pom hauv daim duab. Kuv chav nyob ruaj khov tau tsim rau ntawm kab laug sab tab sis ntau yam ntawm lub zog thiab lub peev xwm tuaj yeem tuaj yeem tuaj yeem siv tau zoo heev (thiab kuv tau dhau los ua cov hnyuv ntxwm klunge) uas kuv tsis tau sim suav nrog kev teeb tsa li ntawd. Koj tuaj yeem siv qee yam zoo li no rau qhov hloov pauv mus tas li yog tias koj tsis xav mus dhau los ntawm kev ua haujlwm/kev hla/txuas kev mob taub hau Kuv tau hla dhau ob peb hnub dhau los.

Qhov tsis muaj npe "IC" ntawm no yog MCP4131 Digital Potentiometer. Kuv tau sim ob peb digipots thiab qhov no tsuas yog ib qho kuv pom (ib qho SPI lossis I2C) uas tsis ua rau hnov hnov thaum twg yog Zero-hla hla kev hloov pauv hauv lub lauj kaub tus nqi.

Qhov ntsuas hluav taws xob nruab nrab ntawm CV hauv thiab ATTiny yuav tsum ua kom muaj qhov hluav taws xob qis ntawm 5v qhov txwv tsis pub tshaj, tab sis nco ntsoov tias koj tsis txhob txwm siv qhov teeb meem tsheb ciav hlau tsis zoo. Kuv tsis tau sim nws tab sis kuv xav tias nws yuav tsis tso koj zoo siab.

Cov tswv yim thiab cov zis tuaj yeem yog 3.5mm lossis 6.3mm-nws tsis muaj teeb meem tiag tiag, xaiv lawv raws li qhov yooj yim tshaj plaws rau koj. Yog tias koj npaj yuav siv nws hauv khib, tej zaum koj xav tau 3.5mm, tab sis yog tias koj xav siv nws ua cov khoom siv ib nrab ib nrab nws yuav ua rau nkag siab siv ib qho, tab sis nws tsis ua qhov sib txawv ua haujlwm.

Kuv ua kuv li kom nws tau siv los ntawm USB tab sis yog tias kuv xaiv Kuv tuaj yeem rub nws tawm ntawm qhov phiaj xwm phiaj xwm thiab muab tso rau hauv kuv Eurorack rig zoo nkauj yooj yim. Yog tias koj xav tau lub zog siv Eurorack koj tuaj yeem siv cov phiaj xwm kuv tau qhia ntxaws hauv kuv li PacificCV Tus Kws Tswj Kev Qhia. Tsis tas li, raws li koj tuaj yeem pom, Kuv pom lub hauv paus rau daim npav daim npav lub taub hau kom siv hauv kuv Eurorack cov qauv ntawm no. (Kuv txawm yuav lawv tawm.)

Yog tias koj tsim tus qauv ruaj khov, nce nws nyob ntawm seb koj xaiv los tsim nws li cas thiab xav siv nws. Yog tias koj xaiv Eurorack version, koj tuaj yeem siv kuv li Kev Pabcuam, Yooj Yim DIY EuroRack Module Qhia tau raws li phau ntawv qhia rau kev tsim vaj huam sib luag. Yog tias koj siv PCB txuas rau lub tsho thiab trimpot, kuv xav kom txiav cov ntawv qhia, siv ib daim duab los qhia tib qhov loj ib yam li lub ntsej muag rau qhov uas koj npaj yuav teeb tsa chav nyob. Pib nrog daim uas ua haujlwm deb tshaj plaws ntawm lub ntsej muag ntawd, taug qab thiab txiav qhov kom haum rau txhua qhov kev tivthaiv (piv txwv li, kos tus qauv ntawm lub hwjchim ntsuas lub zog, tom qab ntawd ntaus lub qhov tawm thiab taug qab cov qauv ntawm lub jacks nrog lub lauj kaub los ntawm nws lub qhov., txiav cov ntawd, thiab ntxiv rau.)

Ib qho kev xaiv zaum kawg yog tias koj xav txuas ntxiv lub tswv yim yuav yog ntxiv qhov "tshem tawm" qhov hluav taws xob rau tus lej qub (CV nkaus txuas nrog sab hauv txuas rau cov lus qhia tso tawm uas tuaj yeem muab lub teeb liab thaum tsis muaj dab tsi ntsaws rau hauv) los ntawm kev ntxiv lwm lub zog nrog tus wiper mus rau tus lej qub thiab lwm ob tus pin mus rau hauv av thiab +5v feem. Qhov no tuaj yeem tsim qhov faib hluav taws xob uas yuav cia koj nruab nrab (lossis lwm qhov chaw) lub teeb liab ntawm digipot thaum tsis ntsaws. Kuv tsis tau ua qhov no txawm hais tias yog tias yog kuv xav tau cov txiaj ntsig kuv tuaj yeem mus ncaj nraim mus rau hauv lub tov khoom.

Kauj ruam 3: Siv

Nws yuav tsum pom tseeb yuav siv qhov no li cas yog tias koj muaj peev xwm siv tau thiab xav tau los tsim qhov no. Ib qho txiaj ntsig zoo teeb liab los ntawm Eurorack daim ntawv synth yuav tsum ua haujlwm zoo rau kev tswj hluav taws xob hauv. Kuv tau siv LFOs, suab sib txuas, ua haujlwm tsim hluav taws xob thiab ADSRs kom deb li deb thiab txhua qhov muaj txiaj ntsig. (Saib daim vis dis aus, thiab hnav lub mloog pob ntseg lossis tso koj lub tso suab hais lus tawm kom txaus kom paub qhov txawv.)

Qhov nce/txo qis ua haujlwm ua rau lub teeb liab poob thoob plaws hauv lub tshuab hluav taws xob, tab sis tseem tuaj yeem ntxiv me ntsis "cua sov" rau cov cim. Hauv kab ke cartesian koj tuaj yeem xav txog nws li txoj kab uas hla.

Kuv tau tsim qhov no los siv, tab sis kuv kuj xav siv nws los ua pov thawj-ntawm-lub tswv yim rau 4 txog 4 quadraphonic (ib puag ncig lub suab) ua ntu zus-sib tov kuv tau npau suav txog kev tsim lub tsev. Nyob twj ywm!
