All you forward-thinking singers who use a harmony processor and play guitar now have the option of adding harmonies to more songs, more easily with the must-have harmonizer, the HarmonyControl | Guitar from TCHelicon.

HarmonyControl | Guitar reads your guitar playing and tells your MIDI equipped harmony processor how to sing "the right stuff". If you've ever used Key and Scale harmony, you'll know it works wonderfully for a lot of songs, but now you can add even more harmony songs to your repertoire while you focus on playing and singing your best. Previously, only MIDI keyboard players had the ability to create spontaneous harmony parts but now it lies in your hands too.

It's Easy
All you do is connect HarmonyControl between your guitar and pedal board or amp. Your pure guitar tone is unaffected; it's as if HarmonyControl wasn't there. A supplied high-quality MIDI cable connects to the harmony processor you've already set up as usual with mic and PA connections. As you play normally, HarmonyControl deciphers the chords in your music and sends it to your harmony processor through MIDI. It's working all the time so that when you lift the bypass on your processor, harmonies flow forth instantly.

It's Versatile
Your harmonizer isn't made by TC-Helicon? Too bad, but the good news is that HarmonyControl is compatible with a wide variety of harmony processors by TC-Helicon and others. Of course, our VoiceWorksPlus, VoiceLive, and VoiceWorks have extended features that make the harmonies even more musical. If your harmony processor has a MIDI input, it's likely HarmonyControl can give you the effortless musical control you've always wanted.

Harmony Control for Guitar w/VoiceWorks Plus

By Robby Wright

from Vista, CA

We purchased this unit for use with a TC-Helicon VoiceWorks Plus vocal processor. Our keyboards are too far away to connect with MIDI, so we tapped the guitar channel on our GL3300 sound console and fed it to the controller. Because of this, we don't get to use some of the features, such as the tuner. We have been using the controller for a week now with good results. When installing the controller, take a few minutes and read the manual, especially the part about needing MIDI in and out cables, which are included with the controller. The manual is well written. Once connected correctly, we had little problem with the controller. It is fun to watch the chord values change on the vocal processor. The controller is sensitive enough that it picks up chord changes no matter what the volume settings are coming out of the console. You may need to adjust the way you play a bit to get it to pick the right notes. The manual outlines ways to do this. We had some harmonies from our processor that followed some obscure chords, but correcting the settings in the vocal processor cured the problem. This is a neat little box.
