Guitar Looper Fade Out thiab Tremolo dawb!: 5 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Ib zaug dhau ib zaug, thaum lub tshuab hluav taws xob guitar yuav tsum zoo li lub guitar thiab txhua qhov sib txawv tau hu ua qhov tsis xav tau hloov pauv, tsis muaj kev cuam tshuam los ntawm guitar tshwj tsis yog … koj tus phooj ywg thiab lub zog ntsuas, ua haujlwm ua ke!

Xyaum ua si thaum koj tab tom ua si, koj tus phooj ywg tau nquag txav mus los thiab ntim cov khoom tsim tawm thoob ntiaj teb lub npe hu ua Tremolo effect (zoo, tsis yog thoob ntiaj teb: Mr. Fender tsis meej pem Tremolo nrog Vibrato thiab rov ua dua!).

Kuv pib txoj haujlwm no nrog lub hom phiaj yooj yim los ntxiv qhov tshwj xeeb ntawm FADE rau kuv Tus Thawj Coj RC-1 Looper Chaw Nres Tsheb: Kuv nyiam ua si qee qhov riff yooj yim thiab tsim kho rau (… Kuv ntxub ua si ntawm MIDI cov hauv paus lossis cov ntaub ntawv kaw tseg!) cov nkauj tuaj yeem nres tau zoo heev ua ke nrog koj kev ua si, qee qhov zoo dua yog tias ploj mus.

Qhov kev xaiv ntawm FADE tsis tshua muaj tshwm sim ntawm Looper. Kuv muaj DITTO x4 tab sis kuv qhov kev paub nrog nws tsis muaj kev ntseeg tau yuam kom kuv rov qab mus rau kuv tus thawj coj RC-1!

Yog li kuv tau tsim qhov yooj yim digital potentiometer uas ua ntu zus txo lub ntim thiab kuv tau tso cov cuab yeej me me no (Arduino nano thiab ob peb lwm yam ntxiv) hauv kuv tus thawj coj VE-8 uas muaj Looper ua haujlwm.

Tom qab ntawd kuv xav tias: lub hwj chim ntsuas hluav taws xob tuaj yeem ua ob yam. Fade thiab Tremolo.

Yog li kuv hloov kho lub cuab yeej me me los tsim cov txiaj ntsig Tremolo thiab, thaum nyob ntawd, ntxiv qhov kev xaiv Nres Looper!

Thaum kawg nrog txoj haujlwm no koj tuaj yeem:

1. Fade qhov tso tawm ntawm Looper (ib qho Looper)
2. Tsim Tremolo
3. Tswj qhov Nres/Undo/Redo ntawm koj tus thawj coj RC-1 (lossis zoo sib xws)

… Lub npe zoo nkauj rau lub cuab yeej tuaj yeem yog FAD3!

Ps.: Hauv kuv lub hnub qub kev hlub suab paj nruas tsis tau ploj mus hu ua "finisce sfumando" …

Ps. Ps: rau qhov haujlwm no kuv tsuas yog siv cov khoom uas kuv muaj, thov ua siab ntev rau qhov ua tiav!

Khoom siv:

1. Arduino nano cov
2. MCP42100 (digital potentiometer)
3. .1uF ceramic capacitor
4. 7 ntu tso saib - Common Anode
5. 560 Ohm tus tiv thaiv
6. reed relay SIP-1 A05 (x2)
7. concentric potentiometer 50K (lossis 2 potentiometers)
8. footswitches (x2)
9. lub tso suab poj niam jack (x3)
10. lub thawv (nws yog xim hlau)

Kauj Ruam 1: Schematic Piav Qhia

Arduino nano saib xyuas cov haujlwm hauv qab no:

7 Tshooj Zaub (Hom Anode)

D2 -> ib (7)

D3 -> b (6)

D4 -> c (4)

D5 -> d (2)

D6 -> e (1)

D7 -> f (9)

D8 -> g (10)

D9 -> DP (5)

Cov Digital Potentiometer MCP42100

D10 -> CSB

D13 -> SCK

D11 -> SI

Ntawm daim ntawv qhia zaub mov txheej txheem txheej txheem lub zog potentiometer yog pom los ntawm cov generic 14pins IC. Nov tsuas yog cov duab sawv cev ntawm MCP42100.

Tawm tswv yim/tso tawm

D12 -> Tshawb Pom Kev Ntsuas (tawm tswv yim)

A0 -> Nres Kev Hloov Taw (tawm tswv yim)

A1 -> Tremolo/Fade Foot -switch (tawm tswv yim)

A2 -> Fade Time Potentiometer (analog input)

A3 -> Tremolo Speed Potentiometer (analog input)

A4 -> Nres Kev Tiv Thaiv - jack NTAWV (tso tawm)

A5 -> Undo/Redo Contact - jack RING (tso tawm)

Kuv tau siv reed relays rau TIP thiab RING cov zis: me me, ruaj khov tiv toj thiab pheej yig! Hauv Fritz cov lej kuv tsis tuaj yeem pom reed relay SIP-1A05 yog li kuv siv daim duab zoo sib xws tshaj plaws. Hauv cov duab txuas nrog koj yuav pom tias reed relay tsuas muaj 4 tus pin (tsis txhob siv 8 tus pin hauv qhov txheej txheem): cov sab nraud yog kev sib cuag, sab hauv cov kauj.

Kauj Ruam 2: Yuav ua li cas FAD3 Ua Haujlwm …

Txuas koj Guitar Looper rau FAD3 raws li qhia hauv daim duab.

Kuv tau siv 3 lub tso suab poj niam tso:

Nres - UNDO/REDO: qhov no siv tus qauv Boss raug (TSWV YIM rau Nres - RING rau Undo/Redo). Txuas STEREO nkaus rau Boss RC-1 (lossis zoo sib xws) txhawm rau qhib cov haujlwm no rau lub looper.

OUTPUT: qhov no yog rau lub teeb liab tso tawm thiab txuas rau hauv av ntawm 9V roj teeb/lub zog xa mus rau hauv Circuit Court (xyaum ua haujlwm nws zoo li lub ON/OFF hloov). Nco ntsoov siv MONO cable txuas qhov Output no mus rau Amp.

INPUT: qhov no yog rau lub teeb liab nkag mus (hauv kuv cov ntaub ntawv los ntawm Boss RC-1 tab sis tuaj yeem yog koj lub cuab yeej ncaj qha) thiab RING tau siv los tshuaj xyuas tias muaj ib qho cuab yeej txuas nrog. Nco ntsoov siv MONO cable txhawm rau txuas qhov kev tawm tswv yim no mus rau qhov tso tawm ntawm koj tus thawj coj RC-1.

Xyaum yog tias tsis muaj qhov ntsuas txuas nrog cov tswv yim, FAD3 ua haujlwm zoo li yooj yim Nres-Undo/Rov ua dua ob txhais taw-hloov ib zaug txuas nrog lub tso suab cable rau Boss RC-1 lossis lwm tus Boss Loopers: tag nrho Boss pedals xav tau NC hu txhawm rau txhawm rau Ua Ntej lossis Rov Ua Haujlwm/Rov Ua Haujlwm, vim li no qhov kev zov me nyuam khaws cov txiaj ntsig A4 thiab A5 tas li ON nrog siv roj teeb me me. Yog tias koj siv NC txuas koj tuaj yeem thim rov qab kev ua haujlwm thiab qhib kev xa rov qab tsuas yog thaum xav tau (raws li kuv tau hais tseg, Kuv tau siv qhov kuv muaj, thiab cov reed reed tsis yog!). Nias Qhov Nres ko taw-hloov yuav qhib qhov kev sib cuag ntawm TIP, RC-1 yuav tsum nres thiab cov duab yuav pom "S". Yog tias koj khaws nws nias qhov kev sib cuag yuav qhib thiab RC-1 yuav thim qhov kaw kaw. Nias Fade/Tremolo foot-switch yuav qhib RING hu rau, RC-1 yuav UNDO qhov kawg dhau mus thiab cov zaub yuav pom tsab ntawv "r" los qhia tias, yog tias koj nias nws dua, RC-1 yuav REDO tso tseg overdubbing… thiab yog tias koj ua nws cov zaub yuav pom tsab ntawv “U” qhia rau koj tias npaj txhij rau UNDO dua!

Yog tias koj ntxig qhov ntsuas (lossis qhov tso tawm ntawm koj lub Looper) RING txuas nrog hauv av thiab cov tswv yim D12 mus qis (vim tias nws yog INPUT_PULLUP nws ua haujlwm zoo ib yam)

Hauv qhov xwm txheej no koj muaj 2 txoj haujlwm:

1 - nias tus ko taw -hloov pauv sai (raug tsawg dua ib nrab thib ob) thiab FADE kev ua haujlwm tau ua haujlwm: cov zaub yuav pom ua ntu zus los ntawm 9 txog 0, lub ntim yuav qis dua raws li qhov nrawm tau teev los ntawm lub zog potentiometer FADE Time (MAX - > fade-out ntev dua / MIN.-> luv fade-out luv dua). Koj tuaj yeem thim qhov ploj thaum tseem tab tom nias dua Fade foot-switch: ntim yuav nce ntxiv ntawm ob zaug vim tias kuv xav tias koj xav rov qab sai dua! Koj tuaj yeem thim qhov Fade thaum ua tiav yooj yim nias lub Nres taw-hloov: qhov no lub ntim yuav rov qab mus rau qhov siab tshaj tam sim.

2 - nias taw -hloov mus ntev dua thiab Tremolo yuav pib. Cov zaub yuav qhia tus tsiaj ntawv "t" thiab qhov nrawm yuav raug tswj los ntawm lub zog Tremolo Speed. Koj tuaj yeem nres qhov tremolo nias dua tib lub ko taw-hloov lossis nias Stop Stop-switch (hauv qhov no lub looper yuav nres ib yam!)

Kauj ruam 3: Txwv …

Nov yog - paub rau kuv - cov kev txwv:

1. ON/OFF muaj nuj nqi siv lub tso suab tso suab yog qhov ua tau zoo Boss daws kom tsis txhob siv roj teeb yooj yim tshem lub jack. Yog li, hmoov tsis zoo, koj yuav tsum muaj lub qhov tso tawm tso rau lub zog FAD3 txawm tias koj xav siv nws tsuas yog Nres-Undo/Redo ob txhais taw-hloov! Koj tuaj yeem tshem tawm ON/OFF muaj nuj nqi lossis ntxiv ON/OFF hloov lossis ntxig lub dummy jack lossis…
2. yog tias koj siv Tremolo koj tsis tuaj yeem ploj mus! Kuv ntseeg tias tus tsim cov cai zoo tuaj yeem rov sau dua qhov program kom muaj txoj haujlwm no. Kuv yog tus sau tsab ntawv tsis zoo (saib kuv qhov project https://www.instructables.com/B9/ qhov twg kuv piav qhia kuv keeb kwm yav dhau!)…
3. thaum pib kuv siv lub hwj chim FADE Sijhawm los teeb tsa Tremolo Intensity ib yam: hmoov tsis nrog txoj haujlwm no ua kom nrawm nrawm heev, yog li kuv nce qib mus rau +5. Nws ua haujlwm tab sis qhov kev cuam tshuam qhia los ntawm "kauj ruam" no tsis zoo. Kev daws teeb meem ib yam li cov ntsiab lus yav dhau los…
4. Tremolo tau tsim nyob rau hauv "txoj kev qub" zoo li npau taws txav lub zog potentiometer nce thiab nqis: thov, tsis txhob cia siab tias yuav muaj kev ua haujlwm zoo li qub, daim duab peb sab/sinusoid, raj zoo li …

3 cov vis dis aus txuas nrog qhia, meej heev, lwm qhov txwv: kuv yog tus ntaus guitar! Tab sis koj yuav muaj lub tswv yim zoo dua ntawm FAD3 ua haujlwm li cas: txaus siab.

Ps: Kuv tau "koom ua ke" FADE qhov tshwj xeeb hauv kuv Boss RC-1 Looper thiab nws ua haujlwm tau zoo heev. Saib

Kauj ruam 4: Code

Kuv tau sim, ntawm qhov zoo tshaj plaws uas kuv tuaj yeem ua tau, ntxiv cov lus pom hauv qhov program los piav qhia tias txoj cai ua haujlwm li cas.

Xijpeem cov no yog qhov tseem ceeb:

kev tshaj tawm ntawm qhov hloov pauv: lub npe Kev Nkag Mus/Tawm Tawm yuav pab tau yog tias koj xav hloov I/O txoj haujlwm. Kuv tau siv ntau qhov sib txawv nruab nrab (zoo li inter, onOff, latchSim, inc…) thiab kuv paub tseeb tias koj tuaj yeem txhim kho tag nrho cov kev khiav ntawm ntu … tab sis cov cai ua haujlwm

MPC42XXX ib feem tau tshwm sim los ntawm Henry Zhao

ob lub zog thawb khawm Kuv tau txais kev tshoov siab los ntawm Scuba Steve thiab Michael James

7 ntu ntu qhia ib feem yog siv https://github.com/DeanIsMe/SevSeg qhia

Kauj ruam 5: Tsev…

Kuv ntseeg tias ib txwm yog kev coj ua zoo los pib nrog tus qauv: koj kawm tsis raug thiab qhov kev sib dhos zaum kawg yuav yooj yim dua!

Kuv tau siv daim ntawv qhia zaub mov ib txwm muaj.

Txog qhov kev sib dhos zaum kawg kuv tau siv… TOY STORY 4 PUZZLE lub thawv: nws haum rau txhua qhov khoom tab sis nco ntsoov tias koj tiv thaiv hauv qab nrog ib thooj yas kom tsis txhob luv.

Qee cov lus qhia:

• khaws IN thiab OUT kom ze li sai tau
• nruab MCP42100 ze rau IN/OUT jacks kom tsis txhob cuam tshuam
• yog tias ua tau ntxig lub vijtsam nruab nrab ntawm MCP42100 thiab qhov seem hauv Circuit (koj tuaj yeem pom L-puab daim hlau hauv daim duab)
• khaws USB chaw nres nkoj ntawm Arduino nano siv tau
