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.

One of the great developers of this generation

This synth could be used on an Aphex Twin record, and then used happily by kindergarteners for hours. If you need source sound for virtually ANY purpose, snap this sucker right up. Sometimes when I’m “making music,” I come to a point where I’m just aimlessly pressing buttons, turning knobs sifting through sample libraries. If i put SpectrumGen in front of me, suddenly my nothing is given purpose. This developer has impressed the heck out of me and I have most of their apps, have not been let down yet. Thank you!
