Ratings and Reviews


All names taken.

free version is super obnoxious with the ads. i kind of liked the sound though, so i upgraded to pro. not much in the way of extra features there. still like the base sound synthesizer, so as a simple noisemaker it is kind of fun, but it has a LOT of that microclickiness/glitching at the start/end of sounds played, regardless of attack setting, making it of limited use. feels a little slopped together overall. the sound is cool enough that it could be a good app with a bit of developer TLC, but in its current state ... eh.

Good But could use a couple of things


For retro sounds and current lead sounds it's awesome, but it needs to be able to produce sine waves for sub basses. It could also use a polyphony option, but that isn't really necessary. Besides those two things, however, this is a great app and I suggest it.

Must Fix Osc Octave Text!!!


First off, it's a very useful teaching tool. A very simple visual layout of the basic tools needed for subtractive synthesis. Novice synth explorers can get comfortable quickly.

But... The numbering system for the Oscillator Octaves is backwards. 16' is supposed to be the Lowest Octave and 1' should be the Highest Octave. (On a real pipe organ,a 16' pipe is much lower in pitch than a 1' pipe. That's where these values came from.)
