The Donner Essential B1 is a compact analog-style bass synthesizer with a built-in sequencer and a 16-step pad grid, aimed at beginners and desktop producers who want a cheap way into bass synthesis. It covers the classic mono bass voice: oscillator, filter, envelope and modulation, with onboard sequencing so it can run without a DAW. It suits people learning subtractive synthesis or adding a bass line to a small setup. Against rivals in its class it trades deep modulation and patch memory for simplicity and a hands-on layout, which is why owners rate it highly as a first synth.

Owners rate it very highly, mostly for how easy it is to get a usable bass sound and a sequence going. Praise centers on the hands-on controls and the built-in sequencer. Criticism is about the limited voice and the small, sometimes fiddly controls.
The Donner B1 is an analog bass synthesizer and sequencer. It produces deep bass and acid synth tones and includes a VCF, saturation (distortion) and tape delay effects. Its interface won a 2022 Red Dot Design Award.
The sequencer has 128 sequence presets covering a range of musical styles, plus 128 user programmable presets. The silicone keys have a color-changing backlight. You can use them to play synth lines live as well as to sequence.
The B1 has MIDI IN/OUT for connecting external MIDI devices, either for sequencing or to use the B1 as a MIDI controller. A 1/8" audio input connects external sound sources. The 1/4" TS mono Main Out carries the main output signal.
