SpectrumGen vs Mobile MIDI

SpectrumGen is a spectral synthesizer with a minimalistic pixel interface. It's a bit like the PixelWave, but now you can draw the spectrum of sound! Key features: • it is possible to draw the spectrum and play it at the same time; • export to WAV; • eight predefined timbres; • changeable number of octaves (from 2 to 8); • MIDI keyboard support; • Audiobus and IAA support. Dark colors - low frequencies (bass). Bright colors - high frequencies.

Turn your iPhone or iPad into a wireless MIDI controller. Almost any sensor in your phone can be a knob.
