5 Star app, but a problem
07/13/2025

I got this app last year around June or July, it was working completely fine. No problems or anything until recently a couple months ago. Everytime I try to open up the Auv3 extention on Garageband, it would always give me an error “Audio unit extention has quit” or something something like that. I even restarted my phone, it did not work. I even deleted and reinstalled the app hoping it would work, it only worked for a little bit, but unfortunately that wasn’t the solution. I tried smaller things such as opening the app before adding the extention on Garageband. No matter what I do, it doesn’t seem to work. All of my other extentions work fine and have no problems at all other than your app. Please fix this problem if you’re able to 🙏. Thank you.

I can't thank you enough for fulfilling this dream of mine to make music from my soul. You all did such a wonderful job to reach deep into time and space in creating this for all music producers and enthusiasts. This is enhancing my dreams into becoming reality. No words but completely in awe of the surreal feelings when I create such meticulous sound layers in building tracks. This is almost like using the electrode Korg which I had a great experience using while learning the trades of production. This is similar to apps I've used but with more advanced modifications and tweaks. I love this app and I use it either on my iPad or my iPhone. This by far surpasses the endless possibilities of original production. ;);) you are beautiful souls who've made a difference in my life. Music is better with this invention.

Update firmware please

Glitch or bug in program where I’m unable to sync other applicators towards keyboard synthesizer. Before I had no issues in sharing applications simultaneously to create unique vibes or even samples. Crashes upon activation of program, not sure if program is equipped to work with other applicators or just only meant for specific ones when it comes to content creations. Aside from that it has been a great tool and add on for on-the-go use or just simply working from home. The extensive amount of features are overwhelming but in a good way. Many viable options that would suite your needs and make your creations even much more unique. Perfect for all sorts from protégés to advance professionals. Hope new sounds would be introduced in the near future.

When I heard that this app was being released, I had very high hopes for it. This app/synth did NOT disappoint. I’ve been working with it, for about two hours, and I’m hearing all of the sounds that I grew up with. (I was a teen, in the 80’s, and this was my music!) For instance, the preset “DX Bass 1’ is the exact bass, used for the song “Danger Zone”. As soon as you hear it, you’ll instantly recognize it. There’s just so many iconic sounds!!! If you’ve ever wanted a DX7, like I have, and didn’t want to pay collector’s prices for one… Now, you can!!!You may be asking yourself, “How can an app, this true to the synths, that it’s trying to emulate, be free?” Because of the immense generosity of Analog Matthew. If you enjoy this app, please review it, and leave him some kind words!
