This app needs improvements, but the idea is awesome. I like it. ### 2/5 — Audio sounds sampled instead of synth *2026-04-26* 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. ### 1/5 — Not Even Close *2026-03-31* Sounds nothing like the prompt you use to describe the sound you want. ### 5/5 — el fantasma que sabe cantar *2026-03-18* looks ok for now ### 5/5 — Mayor Applicacion de Música *2026-02-17* Necesario ### 4/5 — Yes! *2026-01-19* The possibility’s with this are awesome!Keep up the good work. ### 5/5 — Amazing piano app *2026-01-09* This is the only piano app that can play a kalimba, a violin, or anything else you can come up with! Unlimited possibilities. ## Frequently asked questions about Siren ### What is SynthGPT?
