WORKING CONDITION: Excellent. All functions work and sound great. This is a very deep looper, capable of incredible sound design possibilities. All knobs, LED's, and buttons operate as they should, and the display screen is bright and sharp. The included original foot controller is linked via a TRS cable, and all parameters operate well.

PHYSICAL CONDITION: Good. Some of the paint is worn on the metal chassis, but the face plate graphics are still quite legible. The rack ears are straight, and the knobs and iO jacks are in excellent condition. The foot controller buttons all feel great, and the chassis is in very good condition.

INVENTORY #59261

BRAND: Oberheim

MODEL: Echoplex Digital Pro

FUNCTION: Rackmount Audio Looper

PRODUCT DESCRIPTION: This listing is for an Oberheim Echoplex Digital Pro Rackmount Looper w/ EFC-7 Foot Controller. The Oberheim Echoplex Digital Pro (EDP) is a legendary, highly sophisticated 1U hardware rackmount looper originally developed by Aurisis Research, released under Gibson's Oberheim division in the 1990s, and later rebranded under Gibson. Widely considered one of the most powerful and creative live looping instruments ever built, it treats looping as a dynamic performance tool rather than a simple phrase sampler.

SPECS:

• Audio Quality: CD-quality 16-bit, 44.1 kHz uncompressed digital audio. 
• Loop Time: Originally shipped with 1MB of RAM (12.3 seconds). Most units have been upgraded using 30-pin SIMMs to the maximum 16MB, which yields 198 seconds of total recording time.
• Form Factor: Standard 1U 19-inch rackmount chassis, featuring a distinct retro-cream or white finish (and later black under the Gibson brand).
• Control Connectivity: Features an input for the proprietary EFC-7 foot controller alongside comprehensive MIDI In/Out/Thru capabilities for advanced external mapping.
• Unique Performance Features
  The Echoplex Digital Pro earned its cult status due to innovative manipulation algorithms that are rarely found in modern loopers:
  • The "Multiply" Feature: Allows you to record a short initial loop (e.g., 1 bar) and seamlessly multiply its length to overdub longer phrases (e.g., 4 bars) over it. 
  • SUS (Sustain/Momentary) Functions: Enables functions like Reverse, Half-Speed, or Record to behave as momentary switches. The effect triggers only while holding the button down, creating complex stutter and rhythmic textures.
  • Loop Windowing & Insert Modes: Allows users to dynamically slice, replace, and shift fragments of the loop audio structure in real-time.
  • BrotherSync & Polyrhythms: Two EDP units can lock together using a specialized "BrotherSync" connection for true phase-locked stereo tracking. It also features sophisticated MIDI clock manipulation to output complex polyrhythmic patterns to downstream hardware.
