IBM PS1500 owner manual Specifications, ii Introduction

SPECIFICATIONS

•Polyphony & multitimbricity

Maximum polphony: 32 voices. Multitimbric-

ity: 8 parts (Style/Preset modes) or 16 parts (Song mode). Each part is assigned to a track. In Style/Preset mode, 3 tracks (maximum) are assigned to the keyboard and the other 5 to the auto-accompaniments.

•Sound Generation

The Sounds are based on sampled waveforms (PCM, Wavetables and Subtractive Synthe- sis technology) and elaborated by a series of macro functions. The instrument’s 32 oscilla- tors generate “single” Sounds (32-note poly- phonic) or “layered” Sounds (16 note poly- phonic), depending on the number of oscilla- tors used to elaborate the Sound (1 or 2).

•ROM Sounds

ROM (permanent memory) contains 4 Mega- bytes of ROM Sounds, totalling almost 400 permanent Sounds and Drumkits.

•Sound Edit

PS1500’s macro-edit facilities permit rapid and easy Sound and Drumkit editing to produce edited Sounds (E-Sounds) which are stored in the Presets. The modifications are stored in the Presets to allow Songs, Styles or Presets to load the correct sounds. You can also opt to recall your modified Presets with original Sounds instead of edited ones.

•Sample-RAM

PS1500 is fitted with a battery-backed Sam- ple-RAM dedicated to the storage of Samples. PCM Sample kits can be loaded into Sample- RAM from disk, or can be recorded with the PS1500 sampler, accessed via the Audio/Vid- eo Interface.

•Digital Effects Processor

Two Digital Effects Processors, controlled in real time, enrich the sound with effects (re- verbs and modulations). Two different effects (1 Reverb and 1 Modulation) can be assigned to each Preset and an editor is available to create user-effects which are stored in the Presets.

•16 Track Recording Studio

The 16-track Sequencer includes a series of functions that allow Style, Song/Style and Song recording (real time system), playback and editing. Also featured is a Text function (to display Song lyrics). Song/Style record- ing allows the rapd recording of an 8-track song by using existing Styles. Sequence data is conserved in the battery-backed System- RAM.

•Play All Songs, Chain

The Play All Songs function allows the direct playback of all Songs or MidiFiles present on disk without loading the data into memory. The Songs or MidiFiles play as a medley which you can stop at any time with the Play All Songs button. Song/Styles and Songs fea- ture the Chain function which allows you to chain the Song or Song/Styles in memory and play them one after the other with a single command.
