### 1/5 — Whahapped

*2024-08-20*

I have loved and used this app for several years as an essential compositional tool but all of a sudden several things have changed. First of all the 12th horizontal row has stopped functioning and has been replaced with “tap the matrix” instead of the final row in the matrix.  Second, when you switch it to letter names many of them are replaced by …. Why has my app stopped functioning correctly?

### 5/5 — Very Functional

*2023-03-23*

Does not need sounds.

### 3/5 — Can’t seem to get any sound out of it

*2021-05-14*

And I can’t figure out how to access preferences or anything. The interface baffles me but I don’t wanna vote it way down because perhaps I’m just stupid.

### 5/5 — Great tool

*2021-04-28*

Really good app to do this kind of work for me.
