Synthesizer TB 303 Bassline Customer Insights

1. Some of the sounds that come from this app are amazing and definitely could see utility and usage on this app for recording purposes and I didn't really scratch the surface on the stuff it could do I don't think...Great piece of nostalgia.... Would like it more if it was great piece of recordable software.bsuch a shame there isn't a record or save feature.

2. I wish it had a few more keys but the octave function is fine too.beautiful app , rock solid acid sound, rock solid performance i am missing a delay line effect, would the developer hear this prayer.

3. I CAN EVEN PLAY THE NOTES ON MY ALESIS 25 MIDI KEYBOARD! Keep up the good work RockRelay with some feature updates!I don't make reviews...but as an owner of a 303 Bassline machine myself, this app delivers.

4. App is very good at emulating a 303, but they NEED to put in a save button, a sound preset button, then a record and export option.

5. If you add this, the synth will be a great addition to the android music making collection along with koala sampler and sunvoxRather annoying actually.

6. Would have loved to use a WAV or MP3 file of its sounds with other apps to be able to produce some great tracks.

7. It is a sad attempt which only serves to remind one how superior analog devices are.Got this just for the purpose of playing along with Frank Zappa "Sofa" to determine the bassline or at least parts of it.

8. Good App!Very extensive and dense app and can't really use on mediocre phones but get a semi-fast to fast newer phone or preferably tablet and this app is amazing.

9. Does a good job and at least on my device I can play OVER YouTube audio in split screen.

10. Would of got top marksGreat sound and usability, however I uninstalled it because you can't save patterns or save sounds to .wav file.

11. Still a cool app for just messing around.Very nice to play with and learn programming step sequencers.
