Updated Review:

Every time I use this app, I have to come back to say “What an amazing app! I wish all apps had the sound of this FREE app... I just love it! Thank you Developer! I really appreciate your hard work, and the labor of love that went into the making of this app (FOR US THE MUSICIAN!) all the best, hope you will make something that goes deeper and still keeps the standard of quality that you seem to set for yourself. I would gladly pay $9.99 as I bet would the rest of the fans of this app!

Nitpick Pete ,

Real a short wish list, though.

Excellent pitch control. Settings go deep. Similar to many other apps but has some uniqueness, too. Interesting internal sounds. Weird synth, strange but fun.

Wishing for another LFO and Envelope with more assignable destinations. Cries for assignable Y-axis control for things besides volume ( it only recognizes initial vertical touch location; currently no slide control). Other destinations like timbre, filter, LFO speed and/or depth, etc could greatly enhance the expressively. Last updated a year ago...might have been abandoned?

Still a great instrument and controller.

Oceans in space ,

Perfect plus some!

This is crazy for free. It's functioning as well as I hoped and the internal synth and piano are great for getting rolling. The tuning options are incredible and I think I saw a Chapman Stick tuning! There are split tuning with 5ths and 4ths and many more. The actual pads are responsive and just feels right (for fretboard layout). There is so much more here and I'm guessing it all functions well. Cheers.
