What's new in Thingamagoop 2? Analog VCO controlled by analog or digital signal from Arduino. (A separate Arduino board is not required) ユ Sample and hold, Arpeggios, noise, and bit crush effects with open source code so you can program your own sounds! All the analog sounds of the original Thingamagoop. Controllable LEDacle ヨ Ramp and random waveforms with rate control. New modulators ヨ Square wave amplitude modulator and triangle wave pulse width modulator. Tough, stomp box type body with silk screened graphics in 3 different styles. Easy to access battery ヨ No more screws! Much fuller and louder speaker. CV in and out. Arduino Programmer jack. Easily hook an Ardunio board up to the Thingamagoop 2. Still assembled in Austin, Texas by Dr. Bleep and friends. CV The Thingamagoop has a stereo 1/8″ jack on the side to facilitate control voltage in and out. You can make your own cable very simply or order a nice, shielded one from us. Itメs simply a stereo 1/8″ to two, mono female 1/4″ jacks. Hereメs Dr. Bleep and his band, The Hearts and the Minds, using the Thingamagoop 2 to control a Moog Prodigy. The CV input is not 1volt/Octave but you can use it to make some ridiculous sound! The Thingamagoop 2 can operate from either a 9 volt battery (not included) or a standard 9 volt DC wall wart with a negative (-) center (not included).
