Expressive-Piano's design is based on the familiar piano keyboard layout and from the concept of GeoShred app. This virtual piano keyboard synth helps the player to play expressively without learning a new playing style like GeoShred. The goal of this app is to introduce people to the world of expressive virtual music instruments without learning a new method of playing. Since piano keyboard is a familiar instrument to most people, the learning curve for this MIDI Synth is low. Expressive Piano Synth can send and receive MIDI messages to instruments via the USB OTG cable with MPE (MIDI Polyphonic Expression) or Standard MIDI messages. Through this we can connect with existing MIDI Controller, Keyboards, DAWs, and VST Plugins.

All Parameters are highly customizable and can be modified by LFO’s and envelops like Euro-rack modular synths. The y axis of the synth midi keyboard can control additional parameters. There are lots of pre-installed Analog synthesis emulation patches to start the playing journey of Expressive-Piano Synthesizer.

Upcoming features:
• Recording feature
• More presets
• Direct scrolling feature
• Preset Cloud backup

Feel free to share your thoughts. We will be very happy to learn from you and if you like the app do not forget to tell this app to your friends. Hope you enjoy Expressive-Piano Synthesizer!

It's a good app.. Please can you implement a buffer size option so we don't get the crackling of audio? If implementation is done I'll give it 5 and beyond!

Very buggy / glitchy. The UI doesn't even allow me to connect to my MIDI device. Need a refund ASAP!

This is a pretty cool and fun instrument. I like the expressivity of it for sure. Definitely worth having even if just to noodle around with when you're waiting for the bus or something.

Honestly - this app is AWESOME. Great sounds - interesting keyboard dynamic and the free version has a ton of functionality. Huge thank you to the Dev - this app is a wonderful piece of software. Download it now.

Excellent synth! Out of the world sounds with the reverb. Never found any synth that intuitive and excellent looking on Android. Keep it up the nice work Android Developers.

Really cool synth. Lots of sounds to play around with. It's quite fun. I think it could be pretty useful too. I haven't really dug too deep but it seems like there's a lot you can do with this. And it's free!

One of the best synths/midi controllers for Android! Its MPE and sound design capabilities are top notch and it can even control my computer's MPE plug-ins. Also, great interface. I highly recommend the full version.

Awesome app with great potential! Just wish I could figure out how to scroll the keyboard (so I can get the range I need to play - instead of the C to F -f# maybe configuration on the mobile screen). Maybe the feature doesnt exist currently though.

It great as a standalone. Its like Roli. My reason for downloading it was to use it as a controller for the zenbeats app that doesn't allow for poly because of a bug. I 'm not going to pay for this app without knowing it will work first. Great app otherwise.

Some cool sounds and love the MPE capabilities, which is hard to find on Android. I specifically want it to connect and practice playing my Roli Seaboard Block M, seeing a comment from someone else who said they use their Roli with it. Unfortunately, I can't figure out how to make the connection work. It says that it has connected, but playing the Roli does nothing. Twice it randomly gave me a single note off the Roli, but then nothing. Suggestions?

Incredible! I own a Roli Seaboard and this is virtually the same experience on a mobile phone...plus it's free! Love the amount of control avaliable for each of the sounds. Definitely worth checking out.

This is a review of the free version. It actually looks very impressive. I wish it came with some sort of user guide or even settings, just so I could traditionalise the keys to be black and white. I'm going to get the pro version.

I cannot stress enough on how much potential this app has. It's so fun and awesome to use, the possibilities of production just from this app are seemless, some features in the future maybe could add an edm drum kit, looping or simply more sounds/instruments. I'm shocked to see this is available for free. Kudos to the devs for creating this.

This is an extremely useful, well laid out app. I use it mainly as a portable midi controller keyboard for my mini-synths (being able to pitchbend is an improvement over the keyboard of the hardware synth) but you could also play from a sequencer into this. Makes for a fun and versatile OTG songwriting/jam tool, and an easy way to add pitchbend to synth sounds. The price is accessible and great value for what you get!

Phenomenal. You won't need any other synth for your android device. Subtle Tweaks that would enhance my experience. 1. Enable dynamic control at note onset. So, if I press the key at the bottom, it should start out quietly and then allow me to slide the volume up. 2. Adjust the slider height max value downwards. So I dont have to slide my finger tip between two black keys in order to attain max volume for a white key like "A". (Not sure about 2. though, might wanna experiment first!). Hats off!

early thoughts: cool synth with generous set of parameters, but very buggy—feels like a beta. one time payment for pro is nice, but offering no trial is a major deterrent & seems a bit sus, + I think the price is too high for an app this unstable. my biggest peeve is that many knobs are hopelessly uncooperative and can only turn like 15°—maybe substitute with sliders while working on a fix? mpe functiality is great, but glide is too sensitive. there are many more bugs and issues, but the word li

Bought the pro version. OK, but 2 issues: 1. Sometimes it will start playing a note continously. This might be a feature that I somehow activated, but I can't figure out how to stop it without exiting the app. It doesn't even stop if I unplug the keyboard. 2. If the cable gets knocked or unplugged it creates a new device in the MIDI input menu so I have to reselectand and guess which one is working. Hope both can be fixed.

I have just downloaded the app today. I really like how you're able to apply filters to the sound the synth makes. There are some things that might need some work: For a synthesizer, the learning curve seems to be low, but it's still rather alien to someone like me, who is still learning how to use a synthesizer fully. The app could benefit from a glossary of terms and an explanation of each function. It's unclear how to use microtonal tunings. A tutorial would be extremely helpful.

A very fun, and fully capable micro-synth. Several very useable sounds. It does require a bit of background knowledge about synthesis if you with to create your own sounds so perhaps some instructional help would be nice. I would love to see more presets and a way to minimize the left edit bar so you have full range of the keys on screen.
