Doesn’t sound good

I tried the Qanon instrument and the oud instrument, but they both generated weird noise instead. This app needs improvements, but the idea is awesome. I like it.

Audio sounds sampled instead of synth

Instead of a an actual synth, the sounds produced are sampled. Octaves are generated by pitching or changing speed of sound, which results in longer or shorter lengths of time each note plays. This app would be much better if sounds were actually synthesized and we could play long or short notes. Can’t adjust release or attack either.

Not Even Close

Sounds nothing like the prompt you use to describe the sound you want.
