  • Acid Trippin'
So I needed this little bass synth like I needed a another hole in my head, but when a promotional discount popped up, I couldn’t resist. This device is very simple, has a fun feature set (mine came loaded with the latest firmware, version 1.1.0 as of this writing) and most importantly, sounds awesome! Compared to similar sounding devices, which can be a bit intimidating to work with, Donner is to be commended for the clean design and easy operation of this instrument. If you want to sequence some classic acid bass sounds and want the easiest path to get there, at a bargain price, this is the one. :) ... show more

  • Oh heck yeah
I was on the fence but we needed a small bass synth in our set up and it was on sale and I liked the reviews. I use this this with a keystep pro as the controller ans sequencer. I’m going for sound and sound shaping options but not so much interested in the sequencer. It sounds amazing and what I was looking for. I wish I would have bought it sooner. Easy to shape sound and intuitive. ... show more

  • Outstanding TB-303 knockoff, but noisy
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. ... show more

  • Tremendous fun, terrific value
A small, portable synth with one VCO, two waveforms, a filter, delay, distortion, a key that is easy to play, sequencing, a number of useful built in rhythms. Remarkably easy to get going right out of the box and start having fun with. More connectivity than any of my other synths, which was completely unexpected. The bang for buck, value for money is off the charts. You can’t find a better synth value, right up there with the NTS-1 for inexpensive fun. ... show more

  • Great starter synth
I bought this knowing nothing about synths and I'm still having fun playing with it!

  • Nice to have
I like it a lot it's reyfun and interesting to create new sounds by using it manually compared to digitally on computers nice to have as an adult toy to play around with and can be used professionally if you wanted to

  • This is the best bang for the buck synth you can buy
I am a bassist, and I remember my bass tutor getting into synth bass in the mid '80s. Now I understand why. This thing has been so much fun. I can't express my renewed enthusiasm over music again. And I never stopped playing. It's cheap, it sounds great, it's got features way above it's price point. You'll have fun making music. ... show more

  • Delicate
The switches look like they can be easily damaged so care is needed when storing or taking it somewhere.
