main features:
32 mid size keys
stereo (effects stereophonize the initially mono keyboard and microphone sounds)
2 cheap, hissy and bassless built-in speakers
uncomfortable headphone- style microphone
6 voice polyphony
100 preset sounds
12 preset rhythms (they contain no chords)
monophonic microphone input
59 built-in preset effect combinations, each consist of 1 or 2 combined basic effects
9 effect memory user presets
pseudo- vocoder (envelope follower)
"pitch sensor" sing- to- note converter which shall permit to play keyboard notes by singing, but it is almost unusable because it works only reliable within about 1 octave and otherwise randomly jumps to wrong octaves.
5 drum pads, switchable by 3 buttons to play 2 drum kit (A=normal, B= synth toms/sirens) or as effect intensity controls
record/ playback sequencer
"harmony arranger" (some kind of chord sequencer?)
The PCM sound generator corresponds to Casio SA series instruments. It synthesizes each preset sound by a combination of 2 mixed wavetable samples with different complex envelopes.
6 fusion/ synth pop demo tunes
eastereggs:
This instrument can make even stranger noises by feeding its own sounds through the microphone back into the voice changer. The results are e. g. very eerie, droning, booming and disharmonious noises those can be compared best with the horror movie music that Oskar Sala composed on the instrument "Mixtur- Trautonium" (but the "feedback" effect can do some similar sounds also internally). Also somewhat acid- like tweeting can be produced this way.
