or Yamaha OPN chips) to PCM-based chips, such as Commodore Amiga's Paula. Combined with computer's RAM and disk storage, these chips allowed for longer PCM recordings to be reproduced, and games and other software often used rompler-like software technology to reproduce music, most notable example being music trackers on Amiga. Later computer sound hardware employed hardware rompler and sample-based synthesizers (such as Gravis Ultrasound and E-mu/Creative SoundBlaster) to increase number of voices and reduce CPU usage for sound processing. As the processing power of personal computers grew, these hardware synthesizers were gradually abandoned and sound hardware of contemporary computers now usually has only PCM reproduction converters with all synthesis and reproduction logic implemented in software. Modern computers are capable of real-time reproduction of large number of voices, as well as real-time emulation of analogue sound circuits. With the introduction of digital audio workstations, musicians started to employ more and more virtual instruments, so a market for software romplers, as a source of instantly available sampled instruments, also emerged. Some popular examples of software romplers are reFX Nexus and IK Multimedia Sampletank. References Electronic musical instruments
