Hi, Sitting on the fence on purchasing the helix. Can it do a TC2290 style mod delay. For example the TC2290 can have a sine or triangle LFO with depth and speed/rate where the speed is in kHz so you get a nice vibrato on the delay repeats only. I am using a g system just now with serial 2 routing that can add the vibrato at 4kHz to the delay repeats only but I want more routing flexibiltity. Also on another note how good is the twin harmony on the helix. I use a Digitech IPS-33B just now purely for shimmer and octaves.
