Latest update.

Still Don’t Work.

Wait…

Doesn’t work for iPad?

No funciona

Se abre la aplicación pero sólo funcionan tres de los sonidos, en el tercero se queda colgada una de las teclas sin poder desactivarla. No se activan los sonidos más allá del tercero, se queda parpadeando la opción sin lograr cambiarse el sonido. iPad Pro M4 iPadOS 26.5.2. Solicitado reembolso.

Sysex manager

Wait a minute! could be 5 stars if…. Any way possible to make this to be able to perform similar to the desktop version with Sysex files as a editor and librarian. I though I would be able to send presets to my Yamaha TX7 with this app alone. You can on the desktop version and its free. I paid for the iPad version and I’m shocked that feature was left out, I may need to purchase something else that will due both what I thought this would due since it costed me a fee, PLEASE UPDATE 2026??????

Logic Pro presets deletion impossible

OK, so I’ve been using this app for many many months now. I use Logic Pro for iPad, and recently I’ve been trying to reset my preset list. Though I can’t delete any of my presets that have already been saved so I am not very sure what to do. though I am a vision impaired user, and I was thinking about writing this review upon implementing voiceover accessibility, but I figured it would be much easier to deal with the Logic Pro problem. Other than that, this app is great, and I could definitely use it for my biggest hopes and dreams when it comes to music creation. I plan on making video game music with it kinda like a Sega Genesis, but bigger and better. but, my presets list is too large for me to save anything and know where it is anymore, so if there is a way that the deletion problem can be solved, I would greatly appreciate it if this comes as soon as possible. also the reason I gave this app 5 stars is because it is literally what I’m looking for lol. It’s a great DX seven imitation, and I think it deserves less trash talk then it’s getting at this very moment. I understand there are some problems and yes, I do agree. People should be a bit more lenient to when typing out the reviews that they are writing out, because this app is literally basically the perfect FM synthesizer out there.
