We have created this simple music app for fun: it implements the basic waves of a synthesizer with a 16 step sequencer. This app is completely free, but we would be glad if you would consider a donation to the Red Cross. In 2011, the year we were making this app, the Great East Japan Earthquake struck, and we released it as donationware to support the people affected. The damage from that disaster has still not fully healed, and disasters have continued to occur around the world since then. We continue to ask for your support.
This application has the functions listed below.
- 16 steps sequencer
- Start/stop sequence
- Multi-touch note input
- 32 polyphonic tones + 1 drum track
- 4 waves (saw, triangular, square, sine)
- 4 drumbeat loops
- Drums on/off
- Random notes
- Clear notes
