The Morphor Echon 6 is without a doubt one of the most unusual synthesizers to come out in recent years. Now, you can order the BBD-based analog polysynth from Thomann!
All About the Morphor Echon 6
Morphor Echon 6: Now Available
The Morphor Echon 6 was one of the highlights of Superbooth 25 (see below). The six-voice polyphonic synth uses BBDs – analog bucket-brigade devices – to generate sound. Similar to the Karplus-Strong synthesis method, these resonating delay lines are the source of a wide spectrum of unusual timbres, as proven by the many excellent demo videos.
Until now, you had to get lucky or have pre-ordered early to get your hands on an Echon 6. But now, you can order the synth from Thomann*, with delivery expected in just a few days!
Morphor Echon 6: Analog Polysynth Based on BBD Resonators
[09 May 2025] Every once in a while, a synth comes along that does things a bit differently. One of the most unusual synths debuting at Superbooth 25 is Morphor’s Echon 6 – a six-voice analog polysynth based on BBD resonators.
BBDs – analog bucket brigade devices – played a key role for the Belgian company Morphor from its beginnings. Their first Eurorack module was Plectrum, a BBD-based Karplus-Strong module. They also later released BBD-based chorus and delay modules. At Superbooth 25, Morphor unveiled the prototype of its first complete desktop synth. Born from polyphonic experiments involving six Plectrum modules, Echon 6 is an analog polysynth based on BBD resonators.
The synth features a fully analog audio signal path with digital control. Similar to Karplus-Strong synthesis, the synth engine features an exciter section feeding into a 1024-stage BBD resonator, which is essentially a very short delay line with feedback. However, while traditional Karplus-Strong synthesis uses short bursts of noise to excite the resonator, Echon 6 has a much more complex exciter section capable of a wider range of sounds. In addition to noise, there’s a VCO with continuously variable waveshapes. You can also use an external input signal. A crossfader lets you blend the three sources.
The resulting signal is then fed into the resonator section through a 12-dB input filter. The resonator also offers a second filter in the feedback line for additional sound shaping.
For modulation, Echon 6 has an exciter envelope and four LFOs. Other available sources include the mod wheel, velocity, key follow, and polyphonic aftertouch, which can be mapped to various sources using a mod matrix. The synth is even MPE compatible.
Moreover, Echon 6 is up to 6x multitimbral, with individual outputs for all six voices or parts. It also features a unison mode with comprehensive control. The patch memory holds 72 presets and 144 user sounds.
Price and Availability
While the synth is still a prototype, Morphor aims for a release later this year. The price will be in the €2000 range.
