Mine arrived today from a dealer on the wet coast, oddly I’ve ended up with a twelve bit one?
But I followed the instructions, plugged in expander, updated to the latest firmware, reset to factory, and turned on dithering and verified I’m set to 10 volt range.
Being an idiot these days it’ll take me a while to get used to all of the little modes but the multicolour leds should help.
I plugged mine into an O’Tool to check some shapes and after trouble shooting a weird clipping at 7 volt issue (my fault, nothing to do with the Quadrax) I did some tests and took some pics.
My first thought is that I love that changing shape doesn’t affect ramp length
Second it’s important to note that when compared to Maths, Quadrax’s ‘alternate mode’ will generate similar shapes; in Standard mode, Quadrax generates what we’d expect Exp/Log envelopes to look like.
The other thing I noticed (I’m on the latest .2 firmware) is that Quadrax goes way tighter than Maths and some of my really tight Quadrax shapes don’t seem to get up to a full 10 volts but remember: I’m using an O’Tool which may not track such a tiny spike.
I tried to match Quadrax to some Maths shapes but also took some contrasting pics, without some clever patching it’s hard to get Maths to mimic some of the basic Quadrax shapes!
Here’s what the scope looked like with red being the Quadrax and green being Maths:
