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. That would make it 4 stars.On top of that, some effects like delay, reverb, distortion, chorus, etc. would be the icing on the cake and the 5th star, it would be almost perfect. I CAN EVEN PLAY THE NOTES ON MY ALESIS 25 MIDI KEYBOARD! Keep up the good work RockRelay with some feature updates!

Great little synth app, but not sure where the in app purchases are or ability to remove ads? Also the ability to save sequences would be good, but yeah control wise and sound wise really good.

well designed and nice sounding app, but watching the required ads mutes the audio forever and you can't restart it without losing your work. So, it's effectively useless.
