Sample playback. In addition to the machine's internal 6 MB ROM sampled waveforms, the user could install up to 8 MB (divided into two banks of 4 MB) sample RAM (volatile), via 30-pin SIMMs. The samples could be loaded from the floppy disk drive, or via a SCSI hard drive or CD-ROM attached to the machine, containing an ASR-format disk. The synth even remembered the mapping of samples and sounds used, and requested the appropriate disks for loading in power-up. The TS couldn't import WAV or AIFF format samples as the disk format used was Ensoniq's own, first developed for the EPS sampler, and it wasn't MS-DOS compatible, so the user was limited to loading samples available in the extensive EPS/ASR library.
