Synthesist Hank Mason shared this live performance of his original composition, Prelude and Fugue for the ER-1.

Here’s what Mason has to say about it:

“The Korg Electribe ER-1 has 4 voltage-controlled oscillators — the exact number needed for a 4-voice fugue. So I wrote one. Because it seemed like one of the dumbest things I could do with a drum machine.

This is a Prelude and Fugue for the ER-1, performed live with piano accompaniment on an early 1900s Krakauer Bros. grand piano.”

Gear Used:

• Korg Electribe ER-1 Rhythm Synthesizer
• ‘Krakauer Bros. Grand Piano

At Superbooth 2026, Morphor debuted the ECHON 6, the world’s first polyphonic synthesizer based around BBD (Bucket-Brigade Delay) resonators.

Each of its six voices features a discrete BBD delay-line resonator that tracks the keyboard, producing organic overtones and complex harmonic depth. The Morphor ECHON 6 will generate anything from plucked and bowed strings, to leads and basses, to big pads and evolving soundscapes.

Other features include comprehensive multi-timbral capabilities, a 9×32 modulation matrix, an analog signal path and a one-knob-per-function design.

Features:

• Feedback system with full analogue audio path
• 6-part multi-timbral architecture
• 6× Full analogue BBD resonators
• 6× True analogue VCO exciters
• 4× LFOs per voice (24 in total)
• 4× Random generators per voice (24 in total)
• Custom voice grouping (up to 6 groups)
• Comprehensive unison control
• Extensive modulation matrix (9 sources × 32 destination parameters)
• Global modulation attenuverters
• 216 user presets (6 × 6 × 6 structure)
• 1× 1/4″ mono jack external input
• 2× 1/4″ jack main outputs (L/R)
• 6× 1/4″ stereo jack voice outputs
• 1× 1/4″ stereo jack headphone output (independent level, pre-master monitoring)
• MIDI DIN In/Out/Thru ports
• MIDI USB-C (class-compliant device, no bus power)
• MIDI fully-remote controllable
• MIDI SysEx support
• Firmware update via USB-C
• 19″ rack-mountable (black aluminum rack ears included)

At Superbooth 2026, Analog Sweden debuted the Swen 2 synthesizer, an evolution of their swENIGISER.

Here’s a video overview and demo of the Swen 2 from Superbooth, via Sonic State.

The Analog Sweden Swen 2 is a monosynth, featuring a generative sequencer that offers real-time pattern creation and manipulation.

“While the original design from 1996 still holds its ground,” they say, “the SWEN2 is a child of 2026.”

Here’s what’s new in the Swen 2:

• Ghost OSC2/noise
• 12 mode Proto VCF/A – same as in our eurorack module
• Octave selector
• Fine/coarse tune toggle
• Analog -1 SUB OSC
• Clip drive toggle
• GSEQ generative sequencer
• VCO-VCF source mixer
• VCO/VCF auto calibration/tune
• LFO1 hi/lo, trig & wave toggle
• LFO2 hi/lo, trig, clock sync
• ENV:s trig toggles
• No need for gate converters
• Revised eurorack patchbay
• Dedicated headphone out
• More knobs & switches
• Travel friendly size 20x25x5 cm
• Weight 1.5 kg vs 3 kg

The Swen 2 is expected to be available in June 2026, priced at €699 / $699 USD.
