I/O was also available for multi-channel sound recording and playback. A three-board ISPW provided what was at the time unsurpassed signal processing and audio synthesis power on a single workstation. A single ISPW card cost approximately $12,000US (not including the computer), which made it prohibitively expensive outside of research institutes and universities. And the I860 board : The main server software developed by IRCAM for the ISPW was called FTS ("Faster Than Sound"). The main NeXT client application was a graphical program called Max, developed by
