The Roland S-50 is a 61-key 12-bit sampler keyboard produced by the Roland Corporation in 1986. It featured a 3.5-inch DSDD floppy disk drive and had external CRT monitor support to facilitate editing of samples. It could hold up to 32 samples. A rack-mounted version was also available, which featured expanded memory.[3]
15 to 30 kHz variable sampling rates at a 12-bit resolution, (28.8 seconds and 14.4 seconds respectively) The samples can also be saved to disk (3.5-inch DSDD floppy disk drive).[4]
A rack-mountable version was released in 1987,[5] which also had twice the sample memory (1.5 Mb) and time-variant filters. A less feature-rich version of the S-550 was also available as the S-330. Both can support the DT-100 Digitizer Tablet and an external computer monitor for visual manipulation of the samples on screen.
