Modulin is the world's most customizable synthesizer. It allows for unique personal expression while providing a wide spectrum of visual feedback. The playful colored strings are visually appealing while providing the user with fluent modulation of Modulin's LFO. The LFO replicates the vibrato effect heard throughout an orchestra or choir. The LFO can be set to four different wave types: Sinuous, Triangle, Sawtooth, and Square. It also can be set to a wide variety of frequency ranges. Modulin's oscillator can also be set to these four waveforms, but its pitch is controlled by the strings and a tuning knob. A simple low-pass filter allows you to cut off the unnecessary frequencies. The glide rate knob on Modulin creates a fluent portamento effect and allows for some pretty cool instrument replications. A slider located in the middle of the effects view can be dragged to reveal different effects and extra sound makers. Modulin includes reverb, delay, and chorus. It also contains a separate white noise module. Modulin simulates paraphonicness by allowing for a second VCO multiplied to form a gap of up to 2 octaves. Below all the knobs, an ADSR control allows you to manipulate the attack, decay, sustain, and release of your sounds. Modulin truly is the complete package for channeling your inner-composer. It can even record and store your works of art. A record button allows you to lay down a beat and overwrite it with complex melodies. The tracks button allows you to manage your tracks as you add them. New to synthesis? No problem. Modulin has an explore section that takes you through every component in an analog synthesizer, describing what it does alongside a diagram of how signals flow through it. Master of all things musical? Modulin's got you covered again. You can change the root note, octave, and type of scale that Modulin uses. If you feel really confident, you could even turn off the note names in the settings and try to memorize where everything is. With over 40 presets and other preset packages to buy, you will never run out of new and unique sounds. Even if you do, you can create your own and save it for later or share it with friends by the swipe of your finger. Fat fingers? Don't worry. With Modulin’s design, you can plug in an external MIDI keyboard and play it however you like. You can even map certain knobs on Modulin to knobs on your keyboard. It's magic! The more you explore Modulin, the more fun it becomes. You can personalize it by adding your own custom color or amp up the expression through the pressure sensitivity setting.

Verdict
The clearest difference is in-app purchases: EduSynth at none against Modulin's 1. EduSynth also leads on review sentiment (100% vs 69%). Modulin's advantage is iOS requirement (10.0 vs 17.0). On price, ads and device support there is nothing between them.
