Randomwaves built Synthgirl Mini as a pocket-sized wavetable synthesizer that doesn't compromise on sonic depth, packing a 550MHz ARM Cortex M7 processor and 24-bit audio into a genuinely portable format that fits the "mini" designation without feeling like a toy.
The heart of Synthgirl Mini is its dual wavetable oscillator engine, each capable of loading custom wavetables up to 256 steps from tools like Serum, letting you import your own sonic textures or explore the included library. Four shaping LFOs with 25 prebuilt modulation types give you serious movement and character, while the multimode dual filter handles lowpass, highpass, bandpass, and band stop modes with full parameter control. The 5-inch color LCD display with capacitive touch controls makes navigation intuitive, and you get a built-in parametric EQ plus two effect channels with eight algorithms including delay, chorus, flanger, phaser, compressor, expander, overdrive, distortion, and bit crusher, rounded out by an independent reverb engine. An arpeggiator with adjustable rate, pattern, chord, order, and octave settings adds quick melodic possibilities, while the sequencer handles pattern creation with quantization down to 1/64 note resolution.
Connectivity includes USB-C for power and data, MIDI in and out, sync in and out for hardware synchronization, an SD card slot for loading samples and saving your work, and an STM32 interface that invites firmware hacking and customization. The open-source architecture means the community actively contributes improvements and custom features, making Synthgirl Mini feel like it grows with your needs rather than staying locked in place.
