This Philips "sweet Dreams" cradle player/sampler doesn't need much to enjoy.

 I tried adding a pitchbend, but it was shallow and unreliable, so I left it off. 

I added normaly open switches for faster acces to record and play and a mini-jack input I never use. It works fine blowing and chanting into the microphone.

I like to fade it's sound in and out moving the speaker underneath into a cheap vintage microphone into the Kaoss pad.

PHILIPS Baby Care Sweet Dreams Cradle Player

 model SBC SC 150

(from the advertising, electri-fire comments in bold)

Cradle Player is truly a unique and welcome addition to any baby crib. Only the Philips cradle player allows baby to hear a soothing 60-second recording of your own familiar voice.

• Records 1 minute of a parent's voice to help baby sleep
• Premium audio quality  (NOT! Distorting and hissy, but that's why I like it the more)
• Pre-recorded natural sounds  (babbling brook, heartbeat) and lullaby (cheesy piano tune)
• Adjustable playing time  (always put this on maximum)
• Softly glowing night light  (that's cool)
• Gentle fade-out of sounds and light  (yea, too bad)
• Requires 4-AA batteries (not included)
