Powerful little overlooked synths can pack a bite

Fm monster like no other

Aka monkey dope

If you like full on destruction and sounds that break the rules ....spend some quality time with my favorite FM synth!The iPad is my synth lab on the go ! And this guy (the developer)really cares about making the loaded iPad the ultimate host for amazing synths like this little gem! Which if you haven't had the pleasure of exploring it's totally amazing interface..then do yourself a favor and grab this one as quick as you can! Amazing ! Fm synths on the iPad are shamed by this little beast that has some quirks like the saving method ..but the tonal character of this synth is worth it BIG TIME!peace christo

Simple, functional universal synth


I actually purchased this to complete a bundle after owning his EGDR808 app, which I like. This synth has a small file size and is relatively straightforward. Most of the sounds are 80's/FM sounding and I found them to be pretty good. The synthesis is not as deep as you would find in other popular apps, it could have used some more presets, and the control knobs can be difficult to use. On the plus side, it has a scale-based keyboard which is a useful function, and it can be MIDI controlled. This is a nice alternative synth if you are looking for another option.
