PCM Playback

SM-PS50 is a 16-polyphonic bi-timbral PCM playbacker.
It has the following 20 instrument samples.

Piano 1 / 2
E Piano
Harpsi
Clavi
Organ 1 / 2
Vibraphone
Steel Drum
Jazz Guitar
Strings 1 / 2
Flute
Trombone
Saxophone
Synth 1 / 2
Acous Bass, E Bass, Chop Bass

Some samples seem to be velocity switched. The sample rate and bit resolution are not clear.

Bi-timbral

Though nothing is editable with the single sounds, layering parameters can be edited to some extent.

Instrument select
MIDI Channel
Key Limit
Tune Mode (Flat, Pitch Extension I, Pitch Extension II, Werckmeister)
Pitch
Transpose
Oct Shift
Touch mf
Touch p-f
Volume
MIDI receive (OMNI, P. Change, Volume, P. Bender, Modulation, Aftertouch)
Vibrato Speed
Vibrato Depth
Vibrato Delay

Aftertouch works as volume control.
It seems to have no MIDI SysEx - hence no editor - as it has only MIDI IN and THRU, and no MIDI OUT connector.

Chorus

SM-PS50 has one stereo chorus effect.
The parameter is only ON/OFF, and it affects both timbres.
