TC-Helicon - How to Calibrate VoiceTone Singles, Mic Mechanic & Harmony Singer

Occasionally, VoiceTone knobs (pots) need to be re-calibrated. Craig shows you how.
This fix, for knobs that choose the wrong key or style, applies to:
VoiceTone C1, D1, E1, H1, R1, T1, X1, Mic Mechanic and Harmony Singer.
For 2 switch VoiceTone products, like Harmony G-XT, Synth, Correct XT, Create XT and VoiceDoubler, the process is similar. Check out this FAQ for specifics:

[@firefall6]

Thanks! Seriously how is this not in the manual??? I just got a Voicetone C1 and it was off by a half tone out of the box. I was about to return it and found your video. Your method worked on that model.

[@recursiv]

Exactly my experience. The bottom 3 keys were a half-step out. This fixed it easily.

[@litlnemo]

Wow, I was so frustrated with my H1 until I found out about this! There should be a note included in the box. It works now, so I'm happy!

[@bassx187]

Thought my trusty Mic Mechanic was dead. This brought it back to life. Thank you!!

[@JimmiNintendo]

So glad I found this! I'd accidentally got it into this mode, and every time I plugged in the power kept on going into this. Had no idea what was going on! As a bonus is recalibrated. Thank you!

[@ioproductionstudio]

Thank you! I thought I bought not original pedal until I found your solution.

[@mikeymumblesreal]

Thanks Craig!!!.... just noticed after about 5 years, key knob going slightly off. Not bad for 5 years. Great work!!

[@zodiakblk7647]

Very helpful! Thanks for the clear step-by-step process.

[@SingAlongWithLindsay]

Thank you so much! You saved the day- I have a gig tonight and my tc helicon was terribly out of tune. Now it works again!

[@northwoodsounds5041]

Amazing! To the the point and (I think) exactly what I needed. My harmony singer's been a little "off" and hopefully this solves it. Thank you!

[@Vendetta725]

Thanks a lot, Craig. Do keep those videos coming. They are very informative and sometimes laced with your brand of humor. I like them very much. They're never dull to watch and learn from.. :)

[@strangebrutoo]

it worked !!!!! Thanks !!!! I have a Harmony Singer, and it was doing same harmony on 2 different adjacent harmony selections. Plus several others were one notch off.

[@aikodude]

holy hell! i thought my tc was trashed. wish i had found this vid 6 months ago! :) thanks!

[@kevvywevvywoo]

Thanks for the tip, my H1 had the flashing LED out of the box, I thought it was faulty so I did the pot calibration and it's working!

[@joaolu-joaokugland6089]

Sensacional, iria vender o pedal pois não atendia minhas expectativas. calibrei e funcionou perfeitamente. Não vendo mais... muito obrigado.

[@tchelicon]

Hi Vendetta725, the process is very similar for the 2 switch VoiceTone products. I put the instructions link into the description for you.

[@EyeOfWoden]

That link no longer works. Any chance of updating it? I have a 2024 T1 and R1, both of which only have 2 pots. When calibrating, the top-right LED never goes red, and the central LED doesn't flash after calibrating the 2nd pot. Is that correct? Also, I assume there's no way to calibrate the mic gain pot on the side of the pedal?

[@variety_stomp]

Thanks, Craig! Worked like a charm.

[@nimaljayathilaka4718]

Thanks. A helpful video😊

[@ozskipper]

This is great.. Solved the problem with my HS.. Now all I need to find out is why the guitar signal is too hot for it.. Its starting to distort with the guitars preamp only set to half way.. No issues when plugged directly into the desk though.. Weird.

[@derekbrightest]

Great video! Perfect easy solve. You da man.

[@be20101]

Thanks a million, it’s working perfect now 😊

[@zzebowa]

Blimey, this is a fancy bit of kit if it can do that!

[@DoubleMagnet]

My Tc Helicon C1 is at a constant red LED at the top right and the controls on it don’t work. But it is able to pick up my microphone. How do I fix this?

[@audreyshort4357]

You are my hero and yes how is this not in the manual I second that comment!!

[@misformeta]

Worked like a charm

[@eduardocaradine3322]

You are the MAN!!!!! Thanks!

[@KRILLOIL]

I've got two of the Voicetone H1 units which worked beautifully and then went wonky!! I followed your instructions and it fixed one of the units. With the other one, when I hold down the foot switch and plug in the power, the red light does not flicker. Tried these steps a few times, with no response. Can you please let me know whats happening? I use these units for live gigs and I'll be needing them in the next couple of weeks. Cheers Keith

[@OfficialAHEE]

It works!!! Thank you!

[@easytiger1452]

Lifesaver! Thank you!

[@piscesandtherealists4186]

I've tried this method for my Harmony Singer but it does not enter the calibration mode. Any ideas?

[@reallynice3962]

Had this mode come on by accident for the first time just before a show hahah - had to not use the pedal. Nice sounding echoes TBH - Easy to use.

[@michaelrocks9244]

great info, thank you

[@rahulgurungmusic]

My TC helicon H1 is just drop dead, no lights in the power or the LED in the middle. I tried calibrating it and the lights do work the same way as shown in the video but once I finish the process and try to turn it on it doesn't work, it's the same again, dead. Kindly help.

[@Vendetta725]

For Singles, yes. How about for VoiceTone Create XT and Harmony-G XT ? Do these models also require calibration in time?

[@kikogarciadelamata8824]

Thanks :)

[@1OutdoorLife]

Oooooh Thank you so much

[@dancooper9586]

Hi - the red light at the top right of my unit is constantly red whenever power is connected - can you help? It's not working at all and the when I plug in with USB to try update firmware it can't find it.

[@unipluxofficial262]

I bought heliconvoicetone C1 I did as you say, but now I can't go back to normal mode it doesn't emit sound and the light always turns green the one above ??? how do i exit the adjustment mode?

[@nikkovirtucio1899]

I cant seem to exit calibration mode after doing this

[@RozhkovsBand]

very helpful

[@bartmuz]

Very helpful! btw - how often do you need to calibrate it?

[@LarryPalmaa]

This doesn't work with my Mic Mechanic 2 any help?

[@neobx2]

That's great thanks C

[@gandalfleblanc5921]

Bonjour merci pour votre vidéo , pour ma part quand j’utilise tc .. m’enregistrer ma voix sur fl studio j’entends un poke quand je pousse la correction

[@ClassicJukeboxBand]

My TC Helicon C1 Hardtune worked great for 3 gigs, then whamo, the foot switch quit working, even though I put it on top of my keyboard and never used it on the ground. I babied it, took care of it and it failed, even though I did not damage it in any way. I e-mailed Musician Friend, and they said since it was past 45 days, I had to go to the manufacturer to get it fixed. Frustrating to have to do that just like at Walmart. I quit buying electronics from Walmart because I had to return electronic items to the manufacturer, and who knows what results you get from them. To be honest, I expected a lot more from Musician Friend. I shop with them because of their reputation of having excellent customer service, and begged them to take it back, but they refused. Musician Friend did honor their agreement, but I am still disappointed in them. It would cost them almost nothing to take back the old one and send me a new unit, but I guess the profit they save by refusing my request is more important than the thousands I was planning on spending with them in the future. Amazon is the way to go for customer service, not Musicians Friend.

[@tchelicon]

Unfortunately the various retailers have their own policies that we don't control. Hopefully our support guys were able to sort you out!

[@stuartlowe6644]

THANKS

[@braddah1250]

Where can’t I buy that tc helicon form ???🙏

[@gutuelo5566]

Thank you very much. I bought one 5 years ago, it was really helpful. I sole to my friend because i was moved, then I bought one of the same product from BBay from USA. It is far different from the first one. Please brother. The first one i bought in Auckland NZ. Is there a different in this TC-Helicon C1 hardtune and correction. I prefer the first one. Please help.. Thank you Craigs

[@tchelicon]

The calibration process in all of the singles products should be the same. The knobs are labeled differently, but if you follow the order in the video it is supposed to work. If you can't get it going, I'd try support. support.tc-helicon.com/tickets/new

[@howdy000]

What does it mean when my power light stays red the whole time? The fx don't seem to work now.. but I got them working once. That time the light was green.. now it just stays red n no fx

[@dancooper9586]

I now have same problem.

[@arnulfosediego5919]

I tried it on my H1 harmonizer singer but it did'nt work 😢😢😢😢

[@ChristianT1031]

Mine won’t even do anything no matter what I try do you have any clue what I should do?

[@sansmattia]

i love you

[@lynnseward8404]

Does not work that way on Mic Mechanic 2

[@CLAPTONGIRLSTECHNO]

Thaaaank yooooou!!!👍👍👍

Bom dia meu pedal Harmony Singer não está parando calibrado. Em alguns ele entra todas as vozes...

[@robfriedrich2822]

I give them a try, for it seems to me that T1's deesser doesn't work

[@Sunnywarm12]

Thanks my C1 started echoing why? And how to fix that?

[@jackieandedp.4688]

Can I use a mic in front of the guitar amp as the input for pitch correction? And does the input have to have an instrument-out to work?

[@OSPATRIOTASDOFORROOFICIAL]

Como atualiza ela usando computador

[@thanawichsrising5343]

Thanks For did.

[@tarkanyilmaz6905]

After switching toff/on with foot switch like 5-6 times it stops working while the light is still on. I take tge chord out put it back on , it starts working then after switching on/off 5-6 times it stops working again. What can I do to get it working again? Please help

[@crashgeekdicoot]

what should i do if my pedal starts buzzing

[@g.j.armstrong5119]

Hey Craig, can I set my footswitch on my H1 to momentary mode like on the harmony singer pedal ???

[@kiskadar69]

No, you can't.

[@peterkane8786]

.....My TC Helicon Harmony singer 2 is now distorting the harmonies only, no matter how I adjust it, can anyone suggest a way to correct this ?

[@JohnsMusicClasses]

Will you please help me by telling me how to recalibrate the pots on my Correct XT?

[@kiskadar69]

kb.musictribe.com/musickb/view/article/TCHelicon/en_US/VoiceTone-Create-XT-Correct-XT-Harmony-G-XT-Synth-Re-calibrating-the-pots-228160967

[@kiskadar69]

1.While powering on the unit, press and hold "Warmth" and "Pitch" buttons, you will see the "Adaptive" light is on. 2.Turn the Shape knob to the furthest LEFT position that it will travel and press "Adaptive". It should start to flash. 3.Turn the Shape knob to the furthest RIGHT position that it will travel and press "Adaptive" again. 4."Adaptive" should stay on and the second Adaptive button should light. 5.Repeat steps 2+3 with the "Dynamics" knob and second Adaptive button. 6.Both adaptive buttons should stay on and Display should light. 7.Repeat steps 2+3 with the "Pitch" knob and "Display" button. The regular display should kick in a few seconds after completing the process.

[@elbachirmadhoum5308]

Hi i need hate to activate arabic scale hard tune

[@Dweezman]

I purchased a Voicetone C1 (used) but it's completely dead. No lights, blinking or whatsoever.

[@campaudio8273]

Me too bro , mines won't turn on

[@bluesman5049]

I bought a new TC Helicon H-1. When I plug it in, it sounds microphone and hum. Even when the pedal is not activated.When I disconnect the microphone cable, the hum stops. I use XLR connectors and microphone cables. Everything is properly connected. What could be causing it.

[@instituteoj9329]

I have same problem with my H1. So just to lessen the hum, I just lower down the volume control at side of the H1 :(

[@gunter_dierickx]

How do you link up 3 devices with one power plug?

[@KurtCobain2021]

How about the E1?

[@kiskadar69]

You should also do what Craig shows in the video with the E1.

[@walterbenavideshernandez5683]

What I can do if my H1 sounds like IT has a feedback and its New?

[@Im_the_Trashman_]

Will this take a condenser mic since it has phantom power

[@arsonfire1]

Thx. ALot =)

[@uchisensei]

god bless u!

[@maximefortin1472]

It does not work with the harmony singer (2)

[@ragemode8720]

i have a tc helicon H1, and my question is, if the song is in minor key what will i do? All the key is in major,. Hope you can help me,.. Thanks

[@hammerain93]

The major and minor keys have a consistent offset as you go around the musical scale. So, if a song is in A minor, your major key would be C. Each minor key is 3 semitones below its corresponding major key. If you play guitar, think of it like this: If you're playing on the 8th fret as the first note of a major key, and you wish to know where the minor key is, just go down three frets to the 5th fret and there you have it.

[@pietropelosi7787]

Per favore non riesco a calibrare il mio H1, spia sempre lampeggia sempre rossa, aiuto

[@GPD1357]

tell me how to set this pedal to minor scale

[@Demeyez_TV]

I just purchased mine and its on the way. I plan on connecting my XLR mic to this pedal to record through my Focus rite scarlett interface. What other cable will I need to connect my pedal to my interface?

[@tchelicon]

You'll need one more XLR cable. It goes Mic --> XLR cable --> TC-H Pedal --> XLR cable --> Scarlett.

[@Demeyez_TV]

+TC-Helicon Got it, thank you very much. It is scheduled through FedEx to arrive today. I cant wait to start using it.

[@jessiebenavidez7500]

Hello I also have a voicetone double not the d1 but the older one I believe..and it won't boot up when plugged in I get an red 88 for a few seconds then it shuts off. any idea what this is and how to fix it??

[@tchelicon]

Hmm, that might indicate that the power supply has failed, or perhaps something internal. I'd get in touch with support, since they can help out with replacement parts and/or repair if required. support.tc-helicon.com/tickets/new

[@maximefortin1472]

I have a harmony singer 2 and my problem is that the power LED is flashing red, I don't understand...I panic!! Please help me TC - Helicon

[@tchelicon]

Is it running on batteries? If memory serves, that's the low battery warning.

[@maximefortin1472]

No I'm connected with power supply

[@ronydosteclados6150]

Como tirar ruido do desse aparelho

[@eliellima6262]

Amigo se eu posso te ajudar é fazer o processo de recalibração

[@alphonsoamaro2041]

Does the H1 take a 9volt Battery as well?

[@kiskadar69]

No.

[@pamboscharalambous3770]

Anyone knows how to factory reset?

[@patricklbrito1]

Where can I find this explanation in portuguese?

[@greenrobot5]

The problem with my pedal is that it shuts off by itself in the middle of me singing and it's annoying, I step on the switch and it starts again but then it shuts off after a couple minutes, what do I do?

[@eliellima6262]

Amigo se eu posso te ajudar talvez seja necessário revisar os cabos...comigo acontecia isso...revisei os cabos e deixei todos XLR. Não mono. Pra mim resolveu....espero ajudar....

[@kiskadar69]

Turn off the Mic Control function on the pedal.

[@TheSouthdownband]

wonder if this is going to be like my Voice Live Play GTX? i have had it for like 3 years and love it but they stopped having any updates or patches for the firmware a year and a half ago and sorta upsetting since there are so many other users out there that use this pedal and it was not chump change since i bought the switch 3 and the microphone all at once. great unit but poor software support on Tc-Helicons side? still for the most i use my Harmony Gtx and Harmony G more then the vlp gtx since they stopped releasing updates. last one was i think the one that added a little extra time to the looper, but user presets havn't had any updates since shortly after it came out? not knocking TC-Helicon they make some great equipment just try to stay away from the software versions and stick with the hardware only style, i have had to reset the VLP a couple times now do to acting up but never had any issues out of the harmony gtx and harmony g since purchased ! Still love my TC-Helicon gear but think i will stay away from this line of pedals seems to be too many people posting about all the issues they are having with this line and that sucks cause i always like to stay up to date with my pedals :( really want the Tc Helicon Voicelive 3 but just a little to much to throw out this time in life!

[@kiskadar69]

VoiceLive Play GTX is no longer in development, so you won't see any feature updates for that product. It's very common for any company to not develop for hardware that they've discontinued.

[@4catsgg]

Just purchased this. My guitar won't play (amplify) when plugged into H1 (either side) even though mic works through amp. Why is that?

[@tchelicon]

4catsgg The H1 is just a buffered bypass and doesn't do anything to the signal. What are you connecting the guitar output to?

[@4catsgg]

all is fine now

[@tarkanyilmaz6905]

Hello i have the blue harmony singer. when i power it the green light comes on and after 5 seconds turns of but the red ligt comes on. obviously no sound. what do i have to do. ? i tried this calibration thing but when i was doing the last knob

[@tchelicon]

Hi there, did your comment cut off? When you were doing the last knob...

[@jamiebigpapa]

Hi can anyone tell me how to calibrate tc vocal harmoniser?? I’m following the steps on this but getting nowhere. Thanks in advance

[@kiskadar69]

Exactly which device is it?

[@patsygallagher5283]

hi , can you tell me how to calibrate the tc helicon harmony gxt ], please.

[@AxelNotHuman]

why should you have to do this?

[@tchelicon]

AxelNotHuman The potentiometers in the product will slightly change their output voltage range over time, so re-calibration helps the unit re-learn where the end points are.

[@TheDano1947]

My Helicon C-1 doesn't seem to be working. Help!

[@tchelicon]

You can get in touch with support here: support.tc-helicon.com/tickets/new

[@ThirdEyeSmoked420]

hey after having plugged a guitar though the "instrument through" in/out puts, B to G auto correct perfectly, but F# to C all have issues with the scale steps and sounds like its glitching. PLEASE HELP!!!!

[@ThirdEyeSmoked420]

also, still didnt work after following this tutorial, thanks :)

[@joshuasomeone]

Update firmware online. Got to tc helicon website

[@rodtompkinsmusic]

What about Harmony M? I see no mention of it in the directions you provided a link for.

[@kiskadar69]

36/5000 Harmony-M cannot be calibrated.

[@kiskadar69]

Non-USB TC-Helicon VoiceTone devices (Correct, Create, Double, Harmony-G, Harmony-M) cannot be calibrated.

[@pietropelosi7787]

Potresti aggiungere un video per la calibrazione del tc h1 grazie...

[@kiskadar69]

The TC-Helicon VoiceTone H1 must also be calibrated exactly as the C1.

[@DiegoPratsGV]

hi, can you also set the pedal to minor keys ? Thank you !

[@tchelicon]

Yes. You need to use the relative minor. www.simplifyingtheory.com/wp-content/uploads/2014/08/relative-minor.png

[@eddieselph7817]

Hi...I own 3 Mic Mechanics...My band wants to tune down from standard A=440hz to A=432hz...is there any way to adjust the pitch correction function on the Mic Mechanic?

[@eddieselph7817]

I'd be willing to ship them to you and pay via Paypal if it is possible to reprogram them? If it could be done via USB, that would be even better!

[@kiskadar69]

TC-Helicon Mic Mechanic doesn't have any adjustments to the reference pitch. They offer that on their more complex (and expensive) devices.

[@ruaernestomaitan183]

Help me please my Harmony Singer is emitting all the voices!!!!! and is instantly entering in calibratin mode! When i try to calibrate it, in the third knob the red light doens off! help please

[@tchelicon]

[@ruaernestomaitan183]
