Good 303 sound quality, suggested improvements


I like the audio quality of this app, I have two suggestions that would make the sequencer easier to use in my opinion: 1. An option to hear the current note being pressed, 2. Rhythm input mode where you can tap a note rhythm the like the original 303. Cheers, Aron

A serious contender again

David Wilson-Okamura

Drum samples are a bit weak, but the 303 synth sounds great. Now that it has audiocopy and inter-app audio, it's a lot more useful. Thank you, devs.

A couple issues remain: no MIDI clock sync makes it hard to play in time with other apps or hardware; and it's (authentically) awkward to program notes in the step sequencer.

Needs an Update Badly


I really love the layout and sound of this app but it hasn't been updated for so long it doesn't even fill the screen of an iPhone 5 or later. The last update was in 2013. RIP
