Freezing bug!!!

Whenever i go into the menus for selecting soundfonts, they don’t even load, it just freezes and now i can’t use the app i paid for. Please if you would be so kind as to fix this? That would be amazing and mean the world to me. Still amazing app you’ve got here though, it has been SO HELPFUL! And to all those wanting to buy it, please do, it’s an amazing app. It’s totally worth the money aside from that freezing bug but I’m sure the developer will fix it soon.

Response from developer

Version 5.1.2 is expected to resolve this issue. Sorry for the inconvenience.

Frickable

This was a BIT better than a different AU soundfont player called “Fontstack”, however, the downside is that I CANNOT USE DRUMS ON ANY CHANNEL BUT 10, I NEED IT TO WORK ON ALL CHANNELS, WHY MAKE IT SO COMPLEX? FL STUDIO MOBILE DOES BETTER THAN THIS! I JUST WANT WHAT SOUNDFONT I CHOSE TO BE PLAYING! NOT COMPLETELY JAILBREAK THIS APP! PLEASE SIMPLY! I ALSO DO NOT WANT REVERB!

Wavetables not working

Everything works but the only thing that doesn’t is the wavetables every time I try to press library on the app freezes. This only happens on my iPad when I do it on my phone it works perfectly

Version 5.1.2 is expected to resolve this issue. Sorry for the inconvenience.

Amazing app, super fun to use and work with!

My only issue is that MIDI will cut out for a split second sometimes, it’s usually just one audio track but sometimes it’s all of them. (Audio tracks that are bs-16i of course)
Is there any way you could possibly fix this? It can be incredibly noticeable and a bit frustrating at times.

Response from developer

Version 5.0.6 resolved the issue. I apologize for any inconvenience this may have caused.

It’s goated but

It still crashes. I have no idea what keeps causing this and It’s pissing me off. It feels like the system wants me to blame this. Either that or it’s just my storage. It’s still really good but note to self: don’t use too much of it.
