The MIDIvampire-I is a 4-voice, polyphonic synth that is powered from the MIDI data line. So just plug in and play, no batteries required! There are 16 onboard wave tables to choose from, along with attack, decay, FM, AM, reverb, and other effects to shape the sounds to your liking. The output is 14b, 31.25ksps, so it doesn’t sound half bad for its size.
The MIDIvampire-II is a 4 voice drum machine that is powered from the MIDI data line. It has 2 wavetable voices for making kick drums, toms, wood blocks, bells, and a host of other sounds. There is a voice set aside for hi-hats and cymbals, and another which is a filtered noise source, which can make snares and hollow-tube sounds. Each voice has separate attack, decay, and release, along with frequency sweep, and a bunch of other effects for warping the sounds to fit all your percussive needs. And, there are independent outputs for each voice.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
