I use the Eloquencer for more precise sequencing and the Voltage Block for experimenting. It's not really like the Varigate aside from the Malekko brand and imprecise sliders. What I like to do with the Voltage Block is program in arpeggios and short sequences (you can choose pattern length between 1 and 16 steps) quantized to a scale, and then rearrange the patterns on the fly. You can repeat a single step by holding down the button for the desired step, or hold down a few buttons to pick a few steps of a longer sequence to bounce between, as well as traditional up/down/up-down/random. If quantized, the sliders become a little easier to use. I have used the Baseck/Basimilus Iteritas Alter combination too with some crazy results. It's a fun little box with some valuable tools.
