"I had a GREAT time playing it before and will make a video of myself playing later today!! I LOVE it!!" Jordan Rudess via Skype

"It took less than a few minutes to create verse and chorus melodies that work together. In this quick demo I used some free Roland TR-808 samples and a software Korg Wavestation through D16′s Devastor distortion. Truly inspirational." Oliver Chesler -

"I'm not a keyboard player, and the way this app already plays the chords for you, you get a whole new sound from the Sound Module you use." Comment on PalmSounds

F n Amazing!

Only reason I can’t give it 5 stars is because I haven’t been able to see how it interfaces with other apps or DAW’s,...yet. I can’t get off playing with it long enough to do so. This is creative as H! Just when I thought apps on iOS were starting to slow down on creativity, straight up WOW! 🤩

Ok forget it, I’m giving 5 unofficial stars down here for right now, when I finally get to interfacing,...officially 5!

Amazing controller

I use this for hours a day I could go on and on with all the great things I could say, I will however be honest in saying my primary purpose in writing this review is in hopes the developer will see it, I would really love if it was possible to add the ability to transpose octaves mainly down. When using this to control certain things say for instance the bass touch instrument in GarageBand the majority of the available notes are unnaturally high sounding and I have to have the bottom control that adds the octaves selected to try and combat this. I hope you know what I’m talking about the controls immediately to the right of the arrows that select the notes being sharp or flat. I don’t know how else to describe it but basically it’s either play notes way higher than I want or have it sound like an octave pedal is connected which most of the time is fine it would just be nice to have the choice to play lower notes other than that amazing app.

Still a great tool

I've been using soundprism for years and it really helps when you run into writers block when creating a new song. The only issue is that I may have to delete and reinstall on my iPad every so often to get the sound to work again. ( only happens after I use it wirelessly with my DAW) but I will continue to use this app regardless. Great app hands down
