Regular was fine - when I purchased, it kept shutting down. I had to delete and lost $. Sad.

What happens when we destroy the world. This app is dead. I paid for this app too. Nope. Gone. Ive had this app for over 10 years, but not this year. Rockrelay servers are down. Apks shouldnt have to be required to talk to servers. Make the last build standalone, offline. Disable features, whatever. Not this. Then again this app is made in Bulgaria. I really hope war crimes didnt make the synth go bloop.

This looks like a great app, so I don't want to give it a low rating, but it does doesn't open on my Pixel 8 Pro running Android 14. Disappointing, as I really like the idea of a DX7 on my phone! I tried installing and reinstalling the app too, didn't work unfortunately.

I hardly compliment things like this, but I'm telling you now, to whoever made this app, I THANK YOU!!!!! Out of ALLLLLL the piano midis, I've found this to be the absolute best. It doesn't require you to do to much, and the person NEVER changes the app!!!! Ive had this on my laptop for shy of a year to date, and now, I just got a bigger phone, needing a midi for go because I'm a church musician, and dude got this one Good. Y'all trust me, I'm from GEORGIA😂.

Issues with demo version. The interval between commercials is very short to evaluate the app. The volume of the demo version is very low, but the commercials are loud. Is it on purpose for the demo version? Otherwise it works pretty well with my midi sax. The latest update is from 2020, are you planning further updates or the development is frozen?

I used this app lots a few years back. Seems like nothing has been added in a while and I see paid users are still seeing ads & no support. Maybe forgotten about app? I wouldn't buy before having a Dev reply. Good solid 3/5 for low latency. GB,,

I have a lot of synth & keyboard apps. This has become my "go-to". Spent a few bucks, got quick instrument changes, and you can hear the difference in sounds with ease. Fast, easy, and fun, who doesn't want that??

Was not going to rate, but then I saw the Zero Latency tag. Unfortunately the latency is quite noticeable, it is playable, but expect higher latency than you would on a computer. Other than that it does sound great and is a great reproduction of DX7. I do find the price rather steep for this kind of app but if it did produce Zero Latency I would have purchased.

This is a very comprehensive fm synth app, and deserving of a great review, however, there's one small problem that breaks it a bit. If you happen to turn the envelope release to max on any operator, any note played while this knob is in the max position will be left perpetually ringing no matter how envelopes are readjusted. The only fix that I have found for this is restarting your whole phone. Even if you exit the app, the angelic sound of this app will be left humming. 5 stars without bug.

This synthesizer app looks good and seems to sound good. As a multiple synth owner, I hoped to use it for testing song motifs and melodies. Unfortunately, I could not exit the program. Ten minutes in, it's uninstalled now.
