| MATRIX is aide for track making by a pattern based arpeggio.
Pattern making by a 12x32 grid, It supplies an unlimited numerical arpeggio pattern By a pattern editor.
You can make an arpeggio pattern with a grid freely, and a rest (a rest) is effective, too.
With a pattern generator, matrix generate various patterns based on 2 to 8 notes blocks in a grid.
By 4-parameters selected well, you can generate an effective pattern efficiently and easily.
A pattern variation of a block comprising N-notes has number of the factorial of N each, it become a total of 45,264 patterns
only with an original form. and with a combination, it@become an enormous number of patterns. and you can handle it as a pre-set pattern.
Furthermore, you can make an original pattern with an infinite combination by editing with a pattern operator of the grid upper part.
Others, unique harmonic canon effect, As for the recorder, it cope with editing of midi-file unit on DAW software. |
