Notes: Combining an analog filter with unique digital sound sources, all in an easy-to-understand, compact sound package, MeeBlip anode is synth hardware anyone can enjoy immediately. … Read more
Anode is part analog, part digital, capable of producing a range of uniquely aggressive, bass-heavy sounds. And inspired by the best classic synths of the past, getting your hands on that sound is always simple, direct, and intuitive. Simply plug in a keyboard, computer, iPad (via adapter), or controller via the MIDI port to play notes. Then, adjust sounds via knobs and switches - you don't need to navigate a single menu.
Its digital side reproduces the sound and architecture of classic synthesizers, but with an emphasis on adding personality, especially in the low end. Its all-new analog filter with resonance can range from smooth to raunchy - perfect for shaping sound or making squelchy basslines.
Anode comes fully assembled and ready to use. But because it's open source hardware, users can learn from anode by looking through the code and circuits, modifying how it works, or even creating their own instruments based on the design.
MeeBlip is a synth designed to make more and better sounds, with fewer controls in less space. It's designed to have personality in a world awash with synth choices. To create something smaller and simpler, we've focused on building an instrument that delivers grungy, dirty, bass-heavy sounds right away, and puts those sounds directly under your fingers. And we fit it all in a rugged, small and simple 4" x 4" (100×100 mm) box, focusing on just the controls you really need for sound.

We start with digital oscillators built from the original MeeBlip. At the low end, these are generated live with aliasing, for added character in bass sounds. Higher registers use anti-aliased wavetables for clean leads and melodies.
We've focused entirely on getting pulse width sounds just right, with a variable width knob, plus a Sweep switch for adding PWM. You can detune by a full octave in either direction.
These oscillators are paired with an Attack/Decay/Sustain envelope, capable of both fast-clipped percussion and long sustains.
Then, you get a filter with a difference: an original analog filter with resonance, based on a classic Twin T circuit. It behaves like a classic vintage low-pass filter, but in actuality, it's a modified band-pass filter. The upshot: angry resonance and musical frequency cutoff. It's raunchy and aggressive and not-boring - perfect for bass sounds.
Finally, we add an LFO that we've tuned carefully for the best results across the whole Rate and Depth knob, whether routed to oscillator frequency or filter.
Right out of the box, MeeBlip is ready to use - we even include a power adapter. You can be up and playing in the time it takes to plug in a MIDI cable and switch on the power button.
You can play anode via MIDI input, selectable as channels 1-4. And with the exception of the resonance on our new analog filter, every single control can be automated via MIDI Control Change messages, as well as the physical knobs and switches. Audio output is via a stereo minijack (mono on both left and right, for convenience).
As with MeeBlip SE, MeeBlip anode is fully-assembled and ready to go. We believe there are benefits of being open for everyone, not just those who can program or solder. But it's also open when you want it to be - and, just like all the MeeBlips, fully open source hardware (GPLv3/CC-BY-SA). You get an instrument that can be modified, with a design you can learn from, that's future-proofed by being available to a community of musicians.
anode's hardware itself is also more hackable than MeeBlips before. Intrepid hardware lovers can try changing component values to modify the filter - for the first time, this is a MeeBlip with analog mods possible as well as digital. And we have new opportunities for transforming the code. There's still a programmer port, for modifying the firmware via an inexpensive hardware adapter or an Arduino.
