Patching Panda Ephemere
Dual-channel high-resolution CV recorder and looper
14 HP Eurorack module
Ephemere is a high-resolution dual-channel CV and signal recorder for Eurorack, focused on capturing, looping, and manipulating control voltages with precise playback control. Each channel records independently with variable sample rates from 172Hz to 44.1kHz, offering up to 1014 seconds of recording time, with scan, speed, and direction control for creative CV transformation. Its musical character suits live performance preparation, generative patching, and complex modulation design.
Features
- Dual-channel independent CV and signal recording
- Variable sample rate from 172Hz (1014 seconds) to 44.1kHz (4 seconds) per channel
- Dedicated attenuverter per channel; acts as offset/CV generator when no input is patched
- 6 recording modes: Manual, Manual Mult, Sync, Sync Mult, Manual Mult-G, Sync Mult-G
- 3 playback directions: Forward, Backward, Pendulum
- 2 playback modes: Loop and One Shot
- Variable playback speed control via knob and CV input per channel
- Scan control for scrubbing through recorded CV via knob and CV input per channel
- SD card save, load, and erase for signals and settings (up to 16GB)
- OLED display with Live and Playback monitoring modes
- Quantizer with customizable scale (menu items 11 and 12)
- Full per-channel calibration for ADC and DAC accuracy
