Shuttle System Modular Synthesizer

Imagine packing a full Eurorack powerhouse into a carry-on friendly case that fits airline sizers— that's the genius behind this 84HP system, blending five standout modules into one portable beast released back in 2019.

At its core, the Furthrrrr Generator delivers dual triangle-core VCOs with waveshaping, mood index modulation for West Coast timbres, variable pulse width, and ring mod for thick, evolving tones. Grand Terminal anchors sound shaping with dual voltage-controlled envelopes, eight filter modes from ladder and diode to comb and state variable, plus the Cabin Pressure FX processor offering eight curated effects. Shuttle Control acts as the brain, a 16-channel USB/DIN MIDI-to-CV converter with random generators, tap clocks, utility LFOs, and envelopes for endless modulation mapping via web editor. Cockpit handles mixing with four stereo channels, sidechain ducking, and TRRS send/return, while Gateway provides dual utility mixers with auto-tuning for scaling, offsetting, and inverting voltages—all housed in a Frap Tools enclosure at 42mm deep and 2.5kg, complete with PSU and patch cables.

Players love how the Furthrrrr nails complex oscillator duties beyond most rivals, and Shuttle Control unlocks DAW or controller integration without extra gear, though some wish for built-in mono VCAs to round out patching options. It's a self-contained live performer that scales from monophonic leads to stereo soundscapes.[web:4][web:5]
