ModSynth Modular Synthesizer

★★★★★ Stunning! This is the kind of future electro folk computer music tool that Kraftwerk, Devo, and the Human League wrote songs about! Audio and MIDI performance is responsive with my cheap battery powered Behringer UMA25s keyboard (integrated USB audio/midi interface) with an OTG cable to drive a $200. Asus tablet. Has among the lowest latency of all the music tools I use on Android. Very playable and rather Punk. Don't expect Arturia, Reason or Caustic's style of modular synthesis or GUI style. Mod Synth is more like going under the hood of Reactor, and more so reminds me of InDesign's 'Turbo synth' Mac synthesis program from the early 90s - except Mod Synth is realtime and playable without having to render, save, load and key map into Sample Cell or other sampler. Mod Synth has been well-supported with new features added over time, and I just discovered the free Windows VST plugin that loads Mod Synth patches. Adds further to the Turbo Synth vibe! With a cost less than a box of floppy disks - fantastic!

★★★★★ Low latency, works with usb midi, it's a modular synth, and sounds good! Really deserve every penny! With function module you can even create new modules!

★★★★★ It's lots of fun experimenting and creating synth patches with this app's visual editor. Works great with my Akai EWI USB controller or a regular MIDI keyboard.

★★★★★ For the discriminating synthesizer creator/player, this thing is very impressive, and the sounds are excellent. I thought I had an issue with the output through headphones and the developer got right on it to resolve an issue I should have noticed (nothing to do with the app at all). Anyway, because you have to "patch" modules together to make noises/sounds/music, this may not be everyone' cup of tea (in which case I can highly recommend the developer's other app, Easy Synth), but, for me, most of the fun lies with experimenting on patching the various modules in different ways. And the sounds I have been able to create are insane in the best way possible.

★★☆☆☆ When I select to add another module, there is no way of going back to the keyboard. It's stuck on that screen, no buttons to select... Nothing! Only thing I can do is select back on my device.... Which then closes the app all together. Such a shame because the easy synth is fantastic. This has a massive flaw rendering it useless unless I'm happy just playing the pre-sets. Which I'm not. I want to add modules & experiment, that's what this app is all about.

★★☆☆☆ There is a serious issue in this app. My phone hang while editing instruments. Also, the desired sound can not be produced while changing parameters like pitch, attack, release etc., on contrary, that produces weird bad sound than pre-defined sounds.

★★☆☆☆ Frequently crashed or crashed my audio engine. I don't have the most top of the line phone, but Unbox delivers similar functionality without randomly dying or going silent *shrug*. I'm sure it has a flavor all its own that I'm missing out on and others might enjoy, but from what I've seen there are similar, more stable apps available.
