senf app for iPhone and iPad

A simple synthesizer instrument.

When Im on a train or bus, often I play games on my iPhone, spending long time for them. But the skills I earned in a game are not very useful in the real world.

What if it was a musical instrument? At least you might be able to play a song for someone. So, I thought I should make a musical instrument that you can practice anywhere.

senf is a simple monophonic (single note) synthesizer, and was designed to be a musical instrument. As with many instruments, its not easy to play without practice, but it has the following features:

- Play with one hand (use the other hand to hold the device)
- Expressions with sound volume, continuous change of volume / filter and vibrato.
- Play without looking at the screen if it gets used.
