The ELECTRIBE SX (ESX-1), released in 2003 alongside the EMX-1, represents a significant evolution in the ElecTribe family and is considered one of the best samplers of its kind. Housed in a sturdy metal chassis, it features a larger back-lit LCD display and comes with substantial improvements in both capabilities and build quality.
The ESX-1 utilizes sample-based sound creation with 16-part multitimbral functionality and 285 seconds of memory at 44.1kHz, supporting up to 384 user samples. The architecture consists of nine drum parts for one-shot samples (primarily used for percussion), two keyboard parts for melodic sample playback, and specialized stretch parts for tempo-independent loop manipulation and slice functionality. The device ships with 196 preset samples spanning various musical genres.
Working with samples in the ESX-1 is similar to the synthesis process in EMX-1, but focuses on samples rather than waveforms. The sampling capabilities include a "Slice" function that dissects loops at rhythmic peaks, allowing for individual manipulation of segments. Users can modify pitch, filtering, and effects for each slice, while additional editing functions include Normalize, Truncate, and Start Point adjustments.
A standout feature is the Valve Force Circuitry, incorporating two 12AX7 vacuum tubes placed on the top center that impart analog warmth to the output signal. The adjustable "Tube Gain" knob provides dynamic tonal coloration and analog "dirt" characteristic of vacuum tube processing.
The effects section, shared with the EMX-1, includes three simultaneous stereo processors, each offering 16 effect types ranging from reverb and compressor to bitcrushing and pitch-shifting. The filter section provides Low Pass, High Pass, Band Pass, and Band Pass Plus options.
The sequencing environment supports 256 pattern storage (128 factory patterns included). Patterns can be played and recorded for each part, or added directly via the 16-button panel in the lower block. The device features a unique arpeggiator with slider and ribbon controller, providing intuitive control over note length and pitch. All manipulations can affect patterns and be saved for subsequent automatic playback, complemented by step sequencing for recording knob motions and parameter changes.
A significant update in 2010 replaced the SmartMedia card slot with SD card compatibility (up to 32GB), making storage more accessible and cost-effective. The device maintains external connectivity including audio inputs for processing external signals through the onboard effects and additional assignable outputs.
While most sequencer options are intuitive, the sampling and synthesis parameters require some familiarization. The ESX-1 excels in live performance scenarios while maintaining robust production capabilities. The ability to import custom samples significantly expands its creative potential, making it an intuitive yet powerful tool for electronic music creation.
