Wooji Juice has just updated Grain Science (link to review)... a lot! The app is now Universal for playing on your iPhone, without having to buy a second iPhone specific version. They've also added an Animoog style Ribbon Controller, to replace the keyboard. I spent a lot of time this afternoon playing around with it and they really got this right. It plays and feels exactly the way I like it in Animoog.
This is an excellent example playing with aftertouch, from an on-screen controller. Simply assigning the cutoff on a low-pass filter to the keyboard velocity will have you sliding around through harmonics as you play. This is easily one of my favorite features from Animoog, so I am really excited to see it so perfectly reproduced in Grain Science.
This alone would make for a sizeable update, but Wooji has been busy! They've completely rewritten their Arpeggiator, which can be zoomed in to fill up your whole screen. There is now the ability to assign Velocity along with Control A & B, within the Arp, to modulate any of your science. This works just like you would assign the X/Y controllers or a MIDI assignment, through the extensive assignment panel.
Additionally there is the new "G-1000 Shapeinator" effect unit, which applies customizable wave-shaping to your audio. I played around with it a bunch and it is definitely an interesting effect for pushing some wild shit, but I have no idea what I'm doing with it yet. Hopefully Wooji will release another of their excellent video tutorials to explain this one!
