Echo

Analogue Quad Tap BBD Stereo Delay

The Morphor Echo merges the lush, classic warmth of analog sound with modern, flexible control options, delivering a versatile stereo delay module for Eurorack. Taking up 20 HP in your rack, this syncable delay with 100% analogue audio path, features four 4096-stage Bucket Brigade Devices (BBDs) with individual tap outputs and a mix output, creating complex, rich, and textured delay effects with a delay range from 10 ms to 2040 ms. The Echo offers three distinct panning modes—Ping-Pong, Traverse, and Chaos—each with adjustable spread for stereo imaging.

The module supports inverted feedback and offers an external feedback input for additional routing options. Delay time is controlled through a tap tempo button, CV input, or clock sync input, with both quantized and continuous adjustments available. Additional features include CV control for dry/wet mix, feedback, and spread, a phase inversion toggle, tempo output, and a clock sync input that accepts both 1 and 24 PPQN. Whether you need rhythmic precision or organic, evolving delays, the Morphor Echo is designed to meet the demands of creative sound design.

FAQ

• ▸ How do I switch between early and late low-pass filter tracking modes?

  To switch between early and late low-pass filter tracking modes, ensure you are in non-sync mode, then use the A/B switch. Early mode is indicated by a purple LED on the MODE INDICATOR, while late mode shows a white LED.

• ▸ What is the purpose of early tracking mode?

  Early tracking mode helps reduce noise at longer delay times but results in a darker/duller sound due to a lower tracking cutoff frequency.

• ▸ Can I change the filter tracking mode while in sync mode?

  No, you must switch to non-sync mode to change the filter tracking mode using the A/B switch, then return to sync mode. The chosen mode remains active when switching back to sync mode.

• ▸ What is the purpose of the Phase Invert switch?

  The Phase Invert switch toggles the phase of the delay feedback signal, altering the tonality and feedback character.

• ▸ How can I sync the delay time to an external clock?

  Use the SYNC INPUT to sync the delay time to an external clock. It accepts both 1 PPQN and 24 PPQN clock signals, which you can select using a jumper on the back of the module.

• ▸ What are the panning modes available?

  The Echo module has three panning modes: Ping-Pong, Traverse, and Chaos. Each mode distributes the taps differently across the stereo field, adjustable using the Spread control.

• ▸ How do I update the firmware on my Echo module?

  To update the firmware, connect the module to a PC with a USB-C data cable while holding the Tap Tempo button for 3 seconds until the LED turns green. Use a WebUSB-compatible browser to access the Morphor Echo product page and follow the on-screen instructions.

• ▸ What should I do if I hear white noise in the audio signal?

  White noise is normal due to the BBD circuit. To reduce noise, use early tracking mode, increase the clock frequency, apply low-pass filtering on the output, or add filtering in the feedback loop.

• ▸ What is the delay range of the Echo module?

  The delay range of the Echo module is from 10 ms (use Tap 1) to 2040 ms, adjustable through the Delay Time knob.
