Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.
Endorphin.es is a Barcelona-based boutique electronic musical-instrument manufacturer operating legally as Furth Barcelona, S.L. Founded by engineer and hardware designer Andreas Zhukovsky, the company specializes primarily in Eurorack modular synthesizer hardware, including oscillators, drum synthesizers, sequencers, mixers, filters, effects processors, MIDI/CV interfaces, complete modular systems, and more recently standalone effects pedals and instruments. The brand began with the Furthrrrr Generator complex oscillator and became particularly recognized in the modular-synth community for products such as the Shuttle System, Queen of Pentacles, Ground Control, Ghost, Golden Master, Grand Terminal, Blck_Noir, and its compact 6HP/1U module ranges. Its designs commonly blend analog signal circuitry with ARM/DSP-based digital processing and emphasize compact layouts, performance-oriented controls, distinctive industrial design, and experimental sound-design capabilities.
Persistent hiss, whine, digital noise, or elevated noise floor is reported on Milky Way, Golden Master, Cockpit, BLCK_NOIR, Grand Terminal, and some Ghost units. Endorphin.es acknowledges an early noisy Milky Way production batch, while owners have reported similar symptoms on several later audio-processing modules.
Milky Way, Queen of Pentacles, Cockpit, and related audio modules can exhibit unwanted distortion or clipping when input, VCA, saturation, or output stages are driven beyond their usable range. Incorrect rear input-trimmer calibration can also cause signals to distort substantially earlier than expected.
Digital Endorphin.es modules occasionally exhibit freezes, erratic operation, failed updates, or abnormal behavior after firmware changes. Ground Control and Milky Way owners have reported cases requiring firmware reinstallation, factory reset, or SD-card/project-data recreation.
Shuttle Control can fail to enumerate or communicate correctly with computers, MIDI hosts, or connected USB devices. Ground-lift settings, incompatible editor/firmware versions, USB configuration, and firmware problems are common causes of apparent hardware failure.
Shuttle Control and Furthrrrr Generator can develop inaccurate 1V/octave behavior, offset CV outputs, or poor oscillator tracking. Shuttle Control provides per-output calibration and Furthrrrr Generator specifically requires recalibration after oscillator-core replacement or when tuning drifts.
Milky Way and related stereo processors may produce audio predominantly from one channel, an uneven stereo image, or apparently missing output. Stored pan/span parameters, internal settings, calibration, or analog output-stage faults can produce this symptom.
Ground Control users report external-clock synchronization problems including drifting timing, incorrect sequence starts, skipped events, and inconsistent interaction with other sequencers. Clock-source configuration and firmware revisions can contribute, but persistent synchronization faults are also reported after configuration checks.
Ground Control can exhibit interfering MIDI tracks, skipped notes, unexpected slides or arpeggiator behavior, and corrupted sequence playback. Endorphin.es notes that firmware/file-format changes can leave incompatible project data that must be deleted or regenerated.
Cockpit, Ground Control, and other control-dense Endorphin.es modules can develop intermittent or nonresponsive encoder presses, buttons, or mode-selection controls. On Cockpit specifically, proper encoder-button operation is required to access compressor modes, making worn or faulty switches particularly noticeable.
