Analog Bass Synthesizer and Sequencer, Donner Essential B1 with Intuitive User Interface, 128 Patterns Memory, Saturation & Delay Effects, Make for Classic Acid Sound

You'd be surprised how nice this product is for the price point, but Donner delivers once again. All-in-all, this is a pretty basic bass synth, but it sounds nice through an amplifier, headphones, and speakers, and it's surprisingly premium-feeling for its budget price point. I haven't used all of the features this piece offers yet, but what I have used so far is extremely intuitive and honestly just fun, as a good synth should be. Add into the mix that the build quality is stellar and far above what you'd expect for such an inexpensive analog synth and it also just looks gorgeous that I'd say it's a synth that earns a spot on even a veteran rack with the fantastic experience and versatility it provides. I would certainly recommend.

A great and easy to use Acid Beat machine. Great to hook to other MIDI beats.

It's a 303 clone, what else is there to say. The firmware update to add song mode is great, you can chain patterns, so up to 256 steps. The effects are just so-so. The distortion adds a lot of crunch, but the echo is a bit weak, even at full setting it is barely noticeable, it's there, but barely. Nice that it has midi in/out, a headphone stereo out and a mono line out. The sync in and out can be set for various other small instruments, pairs with my korg volcas. One big advantage I see over other clones is the free software, lets you download all the patterns, edit them and load them into the unit. With 128 patterns, you may not need more, but, it is nice to not have to do all the programming via the panel. All this for under $100 when on sale! I was skeptical of the Donnor brand based on other reviews, it's priced perfect to let me play around and I'm not disappointed.

Obviously there are bigger and better bass sequencers out there, but they also have bigger price tags. Cant beat this for the price. Solid build and dead easy to use. Good variety of effects and simple to get up and playing. Full manual available on manufacturer's website. Definitely recommend

Significantly easier to program than an original 303. Sonically....is it an EXACT match? I don't know, and I don't really care. It's got the right vibe and feel, capable of deep, earth-shaking bass and squelchy fat leads, with sick analog oscillators, filters, and controls. I had a Roland TB-3 prior to this, and there were things about the TB-3 interface that were cool, but it was complicated to program actual basslines and melodies, and the touchscreen interface was better at real-time modulation than composition/performance, for me. I like the Donner interface much better. One downside is there is a faint but audible hiss, instead of dead silence, when this machine is not making music. In a live context it would probably be unnoticeable, but in a studio recording, you would want to gate it or noise-remove it after recording.

Sounds good. Fun to play. Lots of good preset patterns. The distortion is good. The built in delay not so much. I use an outboard delay pedal and it's much better. As other reviews have noted, it has a high noise floor. But for the money, the Donner 303 is a good purchase. Hard to justify buying the Roland boutique 303 that costs almost $500.

I'm a drummer who was looking for something to jam along with that I could create my own sequences. I'm into buttons, knobs, switches, and dials. I want to see all the beats in front of me. I'm definitely not into programming patterns in Logic Pro, Ableton, etc. on a screen. I want something tactile and responsive, with all of the options visible at a glance. This Donner B1 is all that. And, it's probably the cheapest analog synth out there. I'm no audiophile, so I can't tell you the differences between this and my Moog machines. I generally make the sequences on this Donner B1, save them, then connect to my Moog Grandmother for tweaking. That way, I can make sequences on-the-go and save them for the Grandmother later. I'd recommend this for anyone remotely interested in sequencing away from a full computer.

Not happy receiving used model, when new was purchased
