SpectrumGen is a spectral synthesizer with a simple and effective user interface. It is a bit like the PixelWave experimental synth, but now you can draw the spectrum of sound!
• multitouch arpeggiator;
• export to WAV (via iTunes File Sharing);
• copy to share with another iOS sound apps;
• eight predefined timbres;
• changeable number of octaves (from 2 to 8);
• it is possible to draw the spectrum and play it at the same time;
• MIDI IN support;
• Audiobus and IAA support.
Dark colors - low frequencies (bass). Bright colors - high frequencies.
Also if you want to draw a waveform directly, check my other app - PixelWave.
Fixed bug with iOS7 UI

If only sharing was easier this would be a 5 star.
Experiment with spectral timbre generation
This program gives you a simple, monophonic spectral synth. You can change the spectrum as you play, and multitouch will alternate between your fingers' parameters. Recording the sound will paste it on the Clipboard, where it can be picked up by a number of programs. Its controls are exactly the same as PixelWave's, the main difference being that you are drawing the spectrum instead of the waveform. So: it's pretty simple. Suggestions for the next release: the low frequency end of the spectrum - which is much more important for building up a fundamental in the timbre - should NOT be colored black - it's nearly impossible to see. Some people may want to save out the spectrum and setup as patches - I realize it's difficult in iOS without good document manipulation support. Similarly, some may want to play the wave via MIDI. So, there's room for a more complicated version of this program.
Very cool spectrum synth!
Amazing little synth for the price. It's positively bursting with sci fi sounds and sonic possibility. The only thing holding back a five star review is the fact that the low frequencies are represented with the color black--on a black background! You can hardly see what you're drawing / manipulating down there. A more neutral background color could easily fox this. It would be really nice to be able to save patches too.
