A Sampling Keyboard with a vast memory and extraordinary editing functions The 16-voice polyphonic S-50 Digital Sampling Keyboard delivers professional quality sound performance and extensive editing capabilities for today's users.

The S-50 offers Wave Oscillation, LFO, an eight stage Envelope Generator, and an Amplifier for each of its sixteen voices. Among its chief attributes are

• 512K word of Wave Memory
• 16-bit processing
• a sampling time up to 14.4 seconds at 30 kHz and 28.8 (14.4 x 2) seconds at 15 kHz
• multi timbral capabilities
• and four polyphonic voice outputs.

Up to sixteen original tones, sixteen modified tones and eight patches can be created and stored. Four patches or tones can be played simultaneously and each patch can include settings for Velocity Switch, Velocity Mix, Velocity Crossfade, Aftertouch Sensitivity, Split Point, and numerous other edit settings. Powerful Edit Functions Your sampled sounds can be edited in two completely different ways with the S-50. On the one hand, the Wave Data Edit Function allows you to modify the actual Waveform Data of a sample. For example,you can merge sampled waveforms, erase the beginning or end of waveform data, or adjust the low-pass and high-pass digital filters. On the other hand, the Tone Para meter Edit function allows you to change the way the data is read, without changing the actual waveform data. This function allows control of envelope settings and loop parameters.

Used together, the Wave Data Edit and Tone Parameter Edit functions are powerful tools that make tone and patch creation surprisingly quick and easy. In fact, every one of the S-50's many remarkable functions has been carefully designed to allow flexibility and ease in creating and controlling new sounds. For example, the envelope generator features a flexible eight-rate and eight-level configura tion. In addition, the rate and level of the envelope generator can be controlled by key velocity and key scale. The key velocity sensitivity can be set to follow one of six different velocity curves.

For added convenience, jacks are pro vided on the rear panel of the S-50 for direct connection of a CRT monitor display Numerous display screens are available for viewing sampled waveforms, envelopes, and all other editing information. The S-50 sampler is based around a "clean computer" design of open architecture This means that the main performance data of Roland sampling is resident in software-software that allows your sampler to be updated with new features and performance just by loading a new disk.
