Since a couple of weeks I have a VL Touch (one). It was supposed to replace my TC Helicon Harmony Singer Pedal, which turned out to be not so practical in a live environment, since there was no chance to connect an external pedal for activating the harmony vocals. Starting with the VL Touch I was highly surprised that my voice sounds by no means as natural as with the Harmony Singer. Also my band mates confirmed that the voice sounds slightly artificial, as if there is a second voice somewhere added. To bypass every potential 'system wise' modification I turned off everything (no doubling, reverb, delay, style, voice correction, mono output) to get an unmodified signal just like the one I'm used with the Harmony Singer. I'm using a Shure SM 58 beta as well as a simple SM 58. On the amp-side I use a high-class AER acoustic amp with a fantastic vocals channel (all parameters flat, no effects), or alternatively a Yamaha power amp. The software is Version 1.20. Did anybody experience a similar problem, or has a clue, why the voice sounds so strange ? My guess is that the VL Touch one uses a technology/ processor which is, compared to the hardware/software of the Harmony Singer, simply too old. In the worst case I would be forced to sell the device, since in that state in simply cannot be used.
