Hi I have been harassing companies for the same thing for a number of years. Here is my request which has fallen on deaf ears:
I am a solo performer. I play guitar and for vocals I use 2 TC Helicon harmoniser G-XT units. I also use 2 microphones and physically move from one to the other for either clean sound or harmonies. It works well and doesn't need any dancing between pedals. My attempts at football have proven me to be chiropidically dyslexic. Is anybody aware of a TC Helicon (or any other company) virtual bass device which provides a range of bass lines (as do many keyboards) controlled by the guitar cords (as in the TC Helicon harmonizer) and controlled e.g. by the midi output of a drum machine. I have identified one which would appear to do the job but is a software based midi system which requires a computer. It also requires an over sensitive Roland Midi pickup and analogue to midi converter unit. I would like one, similar to the harmonizer, in a single box. The technologies already exist in the harmonizer and various keyboards but just need a techno-wizard to re-arrange them into a single "virtual bass" box.
