The Kentron Solton TS 4 K is a strange and obscure Italian keyboard that actually sounds really good. The drum sounds are somewhat similar to Roland TR-909, LinnDrum or other sample-based drum machines from the 1980's. The drum patterns aren't too busy and sound natural. It's built like a tank with a metal case.

Features:
- 32 "Chord 1" sounds and 32 "Chord 2" sounds which can be layered, played automatically or manually with separate volume sliders for each
- Filter cutoff frequency slider control for "Chord 1" sounds
- 16 bass sounds with "Bass Brilliance" slider control
- Different auto accompaniment patterns for "Chord 1" and "Chord 2" sounds with "Custom Arranger" variation that seems to use preset sounds that are unchangeable
- 32 rhythms with a "Custom Variation" for each (64 rhythms)
- 99 saveable registrations (ie. setups including sounds, mixes, rhythm, tempo)
- Separate 1/4" outputs for bass and rhythm sounds
- Separate volume sliders and 1/4" output jacks for 7 percussion sounds
- Manual Drums allows you to play the 43 drums sounds on the keyboard
-49-note, velocity-sensitive keybed
- Pitch bend wheel
- MIDI In/Out/Thru
- Slot for memory card
- Connectors for start/stop/fill-in switch, tonality switch?, effect pedal? and (notes) pedalboard

It uses a massive, external power brick with 5-pin plug and has only 4-note polyphony.

I don't have the owner's manual and couldn't figure out if it's programmable or not.
