  • Carson McClain

    With the V256 Vocoder you do not have to provide the carrier signal from an instrument such as guitar or keyboard because it has a built-in synthesizer. So you can simply connect a mic and start vocoding. There is a pitch knob to change the pitch of the internal synth plus a tone control to change the timbre. There are also two different types of synths. In the Robo modes it's traditional analog synth sound, in the drone modes it is more of an organ sound. You can also play the internal synth with a
    MIDI-capable device!

    Add real-time effects to your voice or use for creative processing in the studio! Consider the VT256 Vocoder and VoiceBox pedals from Electro-Harmonix. I purchased the Vocoder pedal myself and not only am I having tons of fun, but it's becoming an important creative tool in my rig.

    I got this pedal on a whim, just to mess around with it and see what I could use it for. I'm SO GLAD I picked it up. This thing is incredibly fun to play with, but it's also extremely useful in the studio. I actually use it in my monitor mix, set to a mild reflex tune with the wet/dry set to about 50%. The result is that I can hear both my the note I'm singing, and the right note, and as a result, I can pull myself in tune much better. The vocals I've produced using this method are night-and-day better than what I was producing before. Oh, and did I mention it's also incredibly fun to mess around with? Totally worth the cash. Buy one and find out for yourself!

    What I had been waiting for

    Though EHX promoted this primarily as an auto-tune pedal, this is a stellar vocoder, hands-down. The tones it gets are rich and sonorous. The sweepable bandwidth along with the formant knob (gender bender) and pitch knob make it extremely versatile. In terms of a portable vocoder that can easily pop into your effects chain (and has separate outs for the carrier and modulator signal!) this can't be beat.

    The only reason I didn't give it 5 stars is because the signal coming out of the mic output is not a mic-level signal and will easily overwhelm any mic input you send it to. Otherwise it is perfect.

    Good Effects but Limited Output Design

    I've owned this pedal for two years now and have developed mixed feelings about it. First bought it for the vocoder function. The vocoder sounds nice and has a good range of settings available that enable you to create an acceptable vocoder sound. Haven't found any use for the three identical "VOX ROBO" presets slots because the settings don't have enough of an impact to need more than one preset. The output of the device and mic gain (even on the low setting) tend to be very hot. I've had many experiences in live settings where I was unable to use the pedal because of feedback issues. I know that feedback issues can be combated with proper gain setting technique but you can't guarantee that every live venue will have a properly set sound system with a decent engineer. This high output and high gain issue applies to all effect types within the pedal.

    The midi input on the pedal works alright. The internal synth that acts as a carrier signal produces a vocoder sound just as good as what I can get using my moog little phatty as a carrier for the inst input. Triggering the internal synth via midi opposed to an external synth is a little more limited. For example, I can't achieve a glide (portamento) sound with midi internal synth. I've been able to send expression signals such as mod wheel, or octave transposing over midi but not the portamento which really helps create a more realistic, vocal like sound.

    Beware of the outputs and their design on this pedal! This really holds the pedal back in my opinion. Has prevented me from using it in live situations and has also caused major phasing problems before I was aware of the possible design flaw. When the pedal is engaged, it sends the same effected signal through both (INST and XLR) outputs. That's ok in the sense that it gives you a choice in what type of cable you'd like to use for output but it works against you if you choose to use both outputs. I've needed to use the XLR output multiple times so I could sing dry back up vocals while the pedal was disengaged. But when I turned the pedal on for vocoder function it sent two signals to the house pa and the signals phased with each other creating a terrible sound. The dry vocal signal the pedal sends is almost no good because it's so hot. Makes things very tough and inconsistent for a sound guy.

    So now all I use this pedal for is the occasional vocoder effect. I use a total separate mic and line for another other vocal related things whether it's live or at home.
