Exporting all the poses and expressions of a 2D character's sprite can be time consuming. Especially when you have to do it all over again because you changed a little detail...
GrimAce is a free Windows tool for automating that export. GrimAce can open Photoshop files (PSD) and allow you to define your poses and expressions by choosing which layers to export for each. All of that work is saved to a configuration file, so you don't have to do it again.
Melodizer works like an analog sequencer where each step in the sequence is controlled by a column of knobs. However, rather than having a Pitch and Gate knob for each step, Melodizer's main knob is Probability.
