Modelled after Andre Michelle’s ToneMatrix comes a PSP version from developer Babkock, which does pretty much the same thing … it’s a 16-step drum machine, letting you craft some pretty cool sounding beats.
From the README:
ToneMatrix is a 16-step drum machine. The Y (vertical) axis represents eight different sounds, and more than one can be played at a time. The X (horizontal) axis represents one measure in sixteenth-notes.
Select a node on the grid with the D-pad and the X button, and that sound will be played in time. Press O to stop/resume playing, and use /\ (triangle) to clear the grid.
Press START to use the menu, and use the D-pad to select a menu item or change a value (like the tempo), and X (cross) to confirm your choice. Press SELECT for help.
Perhaps next version we’ll be able to export our creations
