Here's a demo of the default ROM sounds of the Casio HT-3000.
Unfortunately, it has no internal battery for memory. So, all user-edited programs are lost and the programmable, internal sounds/patterns revert to their pre-programmed defaults if the keyboard doesn't have constant power from batteries or AC adapter (volatile memory).
Features:
- 40 preset sounds 20 are editable - select from 32 digital waveforms
- 40 preset rhythm patterns 20 are programmable using PCM drum sounds similar to SK-1
- Split-able keyboard with 20 ROM sounds 10 of which are user-programmable
- MIDI In/Out/Thru
- RAM card slot to save your patches, rhythm patterns, etc.
- 61, full-sized keys
- Pitch bend and modulation wheels
- Chorus effect
