The ”Animal keyboard amazing” experiment.

Background info:
I was walking around in the trash room of the basement and I was actually not searching for anything. I was just looking around and was lucky enough to find one of these “animal keyboard amazing” which was thrown out.
Info about the keyboard/features:
| Quote: | • no power switch (instrument is always on and reacts on any key/ button presses)
• red LED flashes in orange window with every sound
• 22 mini keys
• 2 voice polyphony (A keyboard matrix flaw prevents certain key combinations to be recognized, though only monophonic music can be played reliably, but unlike "My Music Center" this keyboard at least has no random behaviour. Due to all sounds but "organ" don't care about the key press duration, 2 voiced melodies can be often played by pressing 2 keys quickly in sequence instead of simultaneously.)
• 8 OBS preset animal instrument sounds {frog, puppy, cow, sheep, kitty, horse, bird, duck} (low resolution 6 bit samples without loop point)
• 2 cute, distorted OBS squarewave instrument sound presets {piano, organ} -6 OBS preset rhythms (with rhythm only monophonic play possible) {rap, pop, waltz, swing, disco, samba} Any rhythms always start with default tempo, which limits the use of the OBS selection for live performances.
• "rhythms sel. " button selects 8 rhythms in sequence. On package box stands {Rumba, bossa Nova, Trot, Disco, Soul, Cha Cha, slow, New Wave}, but in reality these include the 6 OBS rhythms. All rhythms sound very hiphop/ tribal- like and use car horn and sort-of latin percussion.
• 4 drum pad buttons {tom, gon (=gun), carhorn, whstle (=whistle)}
• monophonic sequencer of some dozen notes (2nd voice can be played live) -"demo button selects 16 demo melodies in sequence (very fast and intense, virtuously composed 2 voiced demo melodies with lots of furious instrument changes)
• 4 OBS buttons "song1.. song4" select 4 melodies of the 16.
• 8 OBS buttons select the "singing animals" demo melodies out of the 16.
• demo melodies use more samples than available to the player
• speakers is driven by a single transistor amplifier
• CPU uses a normal internal D/A converter (6 bit?) (no pulse width modulation). |

Inside pictures:
Info: This is what you see when you open the unit at first.
Info: This must be the “voice” board where the samples are hidden behind this melted plastic, which is very common for toys 
Info: This is what we see, when we flip the board, which get trigged by the animals and knobs.
Question:
Any experience or ideas for bending? |

bending, not really  . There usually isn't a whole lot you can do with those 'black blob' circuits except for adding some pitch control (potentiometer/light sensor/touch sensors).
But you can add circuits to it like a filter or sequencer. MIDI control is also an option.
