One thing that I have really come to appreciate about Rack Extensions is that it has given room for all sorts for niche devices that the Props would probably have never bothered with. One category of niche devices is that of CV processors, so we will be having overviews of some of our favorites coming up. As EWI players, wrangling the continuous controller data is critical to what we do. Converting it to CV and being able to manipulate it can really bring your sound design to another level. That being said, one tool I really like is the Revolt CV Processor. The main thing that I like is the big dial that shows the CV data coming into it.
To see the breath data you can hook up the breath output of an RPG-8 Arpeggiator to the CV 1 input of Revolt. Select both devices, right click and select 'Combine' to put them in a combinator. Now, just start playing your wind controller.
I find it quite enlightening to see how I am articulating on the EWI every couple of months and I adjust the breath sensor to be more or less sensitive:
Since the display on the ReVolt goes from -127 to 127 and the EWI outputs only positive CV values, the dial will go from the middle of the display to the far right. To make it go from the far left to the far right, just set up the ReVolt as in the picture below.
The Revolt CV Processor is $9 in the Propellerheads Rack Extensions Shop. Check it out.
