Program Your Backup Patterns and Chord Progressions - a Valuable Assistant for Practice,

Recording, and Composing

It's like having your own session musicians ready to play along with your songs and arrangements. 

The PSS-50 lets you program both the backing pattern (drums+bass+ strings, brass, piano, etc.) and chord progression. You can then play it back to try out different arrangements, make demo tapes, or simply practice your instrument. 

The forty eight built-in backing patterns include 4, 8, and 16-beat, as well as fusion, reggae, disco, ballad, and many more. Each is amazingly realistic and has its own exciting original arrangement. 

Since you arefree to arrange the three parts in each backup pattern as you like, you have a possible variety of 100,000 new and different combinations. With the song writing function you can change the backup pattern and chord progression a bar at a time (or even at every half measure for chord changes). 

The PSS-50 will store eight of your songs for automatic playback. Add breaks and endings just the way you want them. 

The drum section uses digital storage technology to give you real drum sounds that are a far cry from an ordinary rhythm box. Songs can be linked for continuous play or to handle longer compositions. 

The tape interface permits infinite song data storage. 

Other features include external input jack (for mixing with guitar, keyboard, etc.) built-in stereo effect, stereo drum output with fixed array, drum-stick lead-in, and more.
