The PSS-50 SUPER SECTION 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, help compose songs, make demo tapes, or provide accompaniment as you 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 are free to arrange the three parts in each 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 and fillins. The PSS-50 will store eight "songs" of up to eighty bars each-a 640 bar total. Better yet, you can link these to provide up to 1,280 bars of automatic playback. Add breaks and endings anywhere 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. The tape interface permits infinite song data storage. Other features include external input jack with mixing function, echo, stereo output, drumstick lead-in, and more.

The unique PSS60 Programmable Super Section is a new breed of rhythm machine that serves as an indispensable aid to music composition and provides all that you need for creating your own one-man band. Built into the unit are a total of 70 accompaniment patterns, from one of four musical styles (Rock, Jazz, Latin and Traditional), as well as automatic instrumental backing of three parts accompaniment (chords), bass and rhythm. And each pattern has independent variations, such as an intro, fill-in and ending. A special Song Frame function provides exceptional composition convenience by letting you build up a rough outline of your song quickly and easily, before you actually begin recording the parts. Songs are then completed by recording the parts in real time or by step. And you can program up to 99 measures and up to 98 repeats (for a maximum length of 9,703 measures) for each song.

A total of ten songs can be stored to memory, individually or as part of a ten-song medley. The use of a special ROM card allows you to use new patterns with the PSS60 while RAM cards let you store your original song data for future use. The unit is also equipped with an external input for playing with another instrument, and features one-touch operation convenience, with the connection of a footswitch for controlling intro, start, fill-in, ending or block freeze (measure repeat). ln addition, the PSS60 can be used as a sound source module for use with a sequencer or computer music system. The PSS60 also has a split function that lets you control it from an external MIDI keyboard.
