Although this pretty red mini keyboard looks like one of the many My Music Center successors, the sound quality is much higher and it has 49 mini keys with 4 note polyphony, real accompaniment, programmable rhythms and sounds based on quite natural medium resolution samples featuring an astonishingly realistic piano.
polarity protection diode added, AC- adapter jack polarity corrected transpose +/- buttons added
The effect sounds of this instrument sound way less extreme than with the Sankai, which makes them more standard but also more boring. The "echo" is like with Sankai, but the vibrato has only normal depth and doesn't howl extremely in the bass range. Also the "reverb" here adds only a mild and slow stereo symphonic effect which mainly consists of panning with a small dose of phasing but with a way less extreme detuned chorus component. To use the 3 effect buttons, here first the "tone edit" button needs to be pressed (LED lit, doesn't work with rhythm).
The rhythms here are selected by entering a numbers with the drumpads
and then pressing "start/ stop". The accompaniment is always turned off
when the rhythm is stopped with that button, but unlike the Sankai,
here a different rhythm can be selected without stopping accompaniment
by entering its number. Confusing is that the LED at the "rhythm select"
button is lit when a rhythm plays instead of indicating that this button
is currently selected (i.e. drumpads enter rhythms numbers). Here also
during rhythm most button presses make a beep, which is annoying during
live performance. The drumpads here offer 2 banks of each 5 percussion
samples (indicated by 2 LEDs) those can be used to program the user pattern
of the custom drummer. While the "tempo" LED of the Sankai doesn't work,
this instrument has even a chain of 3 green flashing LEDs (similar like
e.g. Yamaha MK-100 or Fujitone
6A) to indicate the rhythm bars.
circuit bending detailsThe "transpose" +/- buttons are connected from CPU pin 27 to pin 1, 2 and the "synchro" button from pin 27 to pin 8. Unlike the 54 keys of the Sankai 01504H, this CPU supports only its 49 keys. Theoretically it might be that anywhere even a MIDI port could be added to this instrument, because my technically similar Sankai has a button labelled "PITCH/ MIDI" although it has no MIDI jacks too. (Due to the well responding 49 mini keys a MIDI output could be quite interesting, although the keyboard is not velocity sensitive.)
The 2 demo tunes are nicely arranged. The first song is a western style ragtime/ charleston piano tune with violin. The 2nd is "Hooray, Hooray - It's the Holi- Holiday" (known from the pop band Boney M.; I don't know the genuine song title) with a jazzy oboe improvisation.
The direct predecessor of this instrument (same case but no accompaniment etc.) was apparently the Quelle 496.996 0 keyboard.
Question: Does anybody know the
original trade name of the K-Mark WP9019A1 keyboard? I saw this
apparently quite rare thing only a few times on eBay (I bought mine
before the Sankai 01504H), but yet never with a model name.
