very good
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. OK...I got the pro version and it looks like you can do a LOT of wav shaping on it. VERY IMPRESSIVE. But.... it doesn't appear to be able to export wav files for use elsewhere. It also has no user guide or instructions, so I'm never likely to use it. Sadly.
very cool app I recommend you try it
cool
Fantstic app. My only problem is that my Samsung phone doesn't have a separate 3.5 audio output. So when I connect the midi cable to the phone I can't send any sound to my mixer or speakers. Is there an adapter to solve this.
it's cool
It's admittedly great but it's not what I was looking for. I want something that plays as a piano
cool
amazing app, exactly what I had in mind when installing. very cheap fee for the premium mode and doesn't require a subscription or repeat purchases.
I love it 😍
I love it
this is 👌
it's cool
still learning but super powerful!
ts is so amazing I'm gonna buy the full version I think
I like how it can make devious. Diesels horn in this app
love it
wow
Best analog for Haken Continuum. All is working again! Please add Tuning! (Pitch bend is hardly editable in Cubase and Nuendo)
it's good, enough bass tho
perfect! thanks! I used this app for a lot of synth tracks for my album Citizen Binary. Thanks and will keep using for future projects.
An excellent tool that gives you a fair amount of electronic sounds. Exceptional quality overall!
very nice. low to no lag compared to other android music apps. Please add gyroscope effects x/y defaulting to vibrato and tremolo.
very good app, I would recommend allowing users to control pitch bend amount to match that of its inspiration, unfortunately while a really good gimmick at this time, this is unusable for me in a professional sense because of this limitation, still thank you for your innovation
Surprisingly it's a genuinely nice instrument app and when I say instrument, I mean they did a good job of actually making it feel like a quality instrument and not just a toy sound app. I'll probably pay for the full version. I mostly love not being assaulted with ads and pop-ups. Even free this is a useful app.
doesn't have popular instruments
cool
It's nice
Amazing. However, I wish all presets had vertical slide control as default, that's like the best part of the app, I feel like the presets used to be somehow more intuitive, idk for sure. The preset selector menu could fit more names into screen at once, there's so much space wasted. Also search tags / categories would be cool. Also small arrows to change the preset without menu. Maybe "Advanced mode" with more buttons visible? Thank u any case, fire app
right when outside. good job on surround sound synths
Fantastic expression, would love a harmonica sound on it though...
Will it work with Novation Launchpad mini for microtonal music?
Great work 👏🏻
Just amazing sounds. The best synth app I've ever had
gorgeous
This Expressive Piano Synthesizer — App'. By Joel K. C. Is An Exclusively Amazing Expressive Piano Synthesizer — App'. By Joel K. C.!!., — Indeedy!!.
crazy music
awesome app
Very badly chosen name. This is just another wave based subtractive synth and is nothing like a piano
midi should be free, one sequiencer needs, best app for internment.
10 of 10 good
J'ai mal aux oreilles à cause de faël. J'ai mis ce commentaire dans le seul but d'embêter un de mes amis, vous ne le méritez pas, vous méritez largement ces 5 étoiles alors les voici. Une bonne journée et continuez ainsi !
This is my Second review since the V2 update. I previously wrote a bad review but I'm amending it. The V2 update is actually GREAT!! Just not with the default settings. If you play around with the settings (modulation especially), you can actually get a great sound. The devs responded to my previous review, so hopefully they'll see this too. Please improve the default settings or add a manual of some sort. This app has tons of potential. Thanks!! — An interested consumer.
Great use of the touch screen this is the only instrument that you literally can't play any other way!
like it does pro come with more presets though?
The new visual effects for the keys are seriously distracting. Can we have an option to turn them off?
I'm loving this synth at the moment. Lots of sounds and a cool vibe.
excellent
most underrated synth, there's so much you can do with this app or even use it as a midi controller. everything is perfectly laid out and the tones are amazing. absolute pleasure using this.
App was fabulous, performed extremely well with midi out for MPE PLUGINS, but after V2 something is off. the expression mapping is wrong. midi values out for daw are wrong. i got the paid version PLEASE FIX THIS.or revert back to older version. it was perfect
good
BEST APP EVER perfectly simulates the seaboard keyboards but can you add basic instruments too? like grand piano, strings (violin strings will be THE BEST) or even guitars or something? just add more instruments and this will be even better edit: can you add a button to switch to the classic ui? because the classic is more smoother looking and better, but I still enjoy the newer one as controlling loudness of the note is more easier to do
Im writing this review to say, i love the previous version of this app so much and i use it all the time, but this update has taken away everything i like about this app. I cant for the life of me find a tone that sounds good anymore. ive been trying different piano apps for replacement, but nothing has come close to this app previous version. please fix, or bring back the old version 🥲
not a musician,Own TD3 x2 HR16 drum mac,pedals,Tablet,Luv your EP,jus getting NoizeUgly & Beautiful to use,An Not jus luck then Swore loudly after update as Im back to wearing 'Dunces'hat,,🤬🤯🫡😭🙂↔️😢, start afresh But thats a me problem,it's a Amazing,Mind bendin, Testing Synth App,If u. know what about synths,& got a Midi keyboard u should luv this straight off,If clueless like me, gonna take alot but for price its. fkn Num 1 imo,
I don't know why you have made it worse with the update when the app was already good. It's buggy, the new interface feels off and uninspiring. Plus frequent crashes. Please fix this and don't make me regret paying for it
update keeps crashing app
i gave it 4 stars because the app works but im struggling to get the pitch bends to work on my roli lumi
I love this one
i bought the pro version and it will not let me use it
awsome
very goooooood .tancks
tes gam is cool i ken play ma3 song end has fooon
very unhappy recording doesn't work upgrade to pro never disappears even though I upgraded
wow
ads for every 10 seconds. unuseable
excellent
Really responsive
God code clean and professional
nice
absolutely beautiful.. if devolopers could just add a scale snap function to it, it'll be just perfect..
Really cool!
iam Anand
like to play together
good
Awaiting RECording feature...waiting...waiting...waiting...... Also, a Harpshicord may prove...interesting.
Poodonk
Returning to the app and finding myself a user-preset called "killer". This really made me think twice before submitting ratings on some of the apps that I use, and have used.
so far so good
super 👍
good apps
I'm like this This is fun and all music,i'm test it
nice this app but not calibration option
Love this app. I use it as a drone generator for scales/modes practice using the hold function.
very nice synth....I like it!
very nice 👍
fantastic!
down load this now
Best One
should have a way to record the playing
really good keyboard!!
Nice!
Unbelievable
Nicely Done. Quality not Flashy. truly like the audio output and seemingly endless tweaking that can be done. Now I just need to figure out how to record my audio ideas and sounds.
besttt thingg in the world for me as a music hobbyst🎊❤️
very nice
cool
awesome 😭😭
well this seems like a very sophisticated creation a masterpiece of works. Magic even, as I know little about what all THIS is and what one can do with it. it's quite phenomenal.
i fux wit it
pl help. i purchase this app for using as midi controler but in daw it is not working modulation & pitch bend. how can i contact you.
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. Samsung Note 10+, Korg Microkey V1
So difficult to play accurately when even the non elevated buttons works as the next or previous buttons
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!
Amazing! Unique, fun, just the right level of depth and complexity, sounds fantastic, couldn't ask for anything more
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.
it was so bad that I literally had to stop playing it and it had a meow sound I did not like it to have a meow sound it literally is sound very bad and warning do not play the synthesizer*for Elise ecklund*
really cool app to make sounds and pass the time that the doctor's office
I was trying the app, and I was enjoying it until this review window just interrupted me! Don't EVER interrupt me.
I bought it because I believe you guys love music. Please add grand piano and synth sounds.
Very buggy / glitchy. The UI doesn't even allow me to connect to my MIDI device. Need a refund ASAP!
After upgrading to pro & unlocking connection with my Casio keyboard I was disappointed the connection was not stable (lag & disconnect). I would like a refund.
wish I could save a sample on the free version, excellent synthesizer
Great app would love the ability to record sounds
Needs a try before you buy option. it recognizes my midi keyboard, but I can't select it and see how well it works, without paying.
it's awesome with impressive touch sensitivity..feels like a real seaboard! I have been looking for this kind of app and finally found it. Thanks.
Somehow easier to play than other android keyboards
This is awesome, please try to include midi over wifi feature in the next update. Thanks.
Latency is almost a full second of delay - how is this useful for actual music? Mainly a toy or noise maker.
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.
Works with the keys of the Akai MPC Mini, but I assumed there would be a midi map function to control the in-app knobs with those one the Mini. So far have not figured out how to do so.
Intuitive to use. The expressive keys are exactly that. Simple, clean UI.
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!
It's great. I would love the option to buy more presets or get them somehow. I am not good at sound design. I just want want to play around and get inspired.
This is a fun way to play music, nice features overall..., edit dev said 5 star review but I only did 4 star as result I will now update this review, 3 star good app but could use some diferent keyboard layouts make make your own layout like a accordion one or other types of input instrument layouts
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.
Cant save my music and export to other extensions, but it very good anyway.
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!
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.
Nice layout. Look like seaboard. If layout customisation is possible, better.
haven't played with it much before it demanded feedback, but seems pretty decent
It's so good app but why it doesn't work with Bluetooth earbuds....
idea espeshely as being A synthisizer to be used for week long air guitar practice I usually like composing jams in the starstreak also good name for a autobot space ship transportion form for a.toy design hopefully hasbro picks that idea up
I've had the pleasure of having experienced hands on the exponential growth of synthesizers over the last 30 years. This little beast knocked off the socks of anything else out there.
I purchased the Pro version so i can connect my midi keyboard. But some keys automatically sustain, its unusable 😔 My midi keyboard is fine as i can use it on my iPad.
this app is super clean and does what it says. I hope it stays the same while adding more sounds. ✨️
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!
For free it has enabled me to create realms of expressive frequencies through drone and pad that have enhanced no end my renewed vigor for worldbuilding projects. Making rich description come to life through the myriad of free ai tools and open source projects sets the tone for a creative age. See, in mixed media forms, galvanized do worlds emerge through words intent to conjure forth seeds of galaxies forming from quasar's. Blessings to the folk who toil on apps like these 🙏🌐🪡✨
Looks and sound good. And I understand paint for s pro version. But I really would like to be able to test the otg midi functionality before paying or it
Paid, nice app 💯 Allow note recording and save if feasible.
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
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.
I approve of this wonderful application installed on this remarkable day. I must admit it was a spectacular experience.
quite good, copy of the hardware, needs more presets and if possible a touch sensitivity! ( btw, in what sense is it analog? cheers )
The best and most intuitive app I've found for Android! A truly amazing app!
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.
This is amazing. Should be a standard instrument like the 808!
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.
Sweet Controls and Massive Potential! Much impressed with everything except the inability to turn the tablet/phone around 180° in order for easier access to the charging port...
Really like this app. Bugs: Lossing sound completly while changing envelope settings. Only fix is app restart. While using touch keyboard, adding keystrokes past 4 retriggers previous key strokes in consequtive order. Virtual keyboard is generaly kind of a mess; aftertouch going down is really short compared to going up and the black keys zone gliding through all notes as opposed to the white key zone gliding only white keys looks like a nice but unintended feature.
It could be amazing to have an option to record and save directly to the phone
Thanks Sir, it's work.. Specially Slide..Sir please Include More Realistic instrument like Pan flute, Violin, Sarangi, Sitar etc.. like IOS Geoshared..
There should be scrolling system, and adjustable key, so that user can adjust the no. Of keys and width of keyboard, plz plz plz 🙏🙏🙏make these changes
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.
Very simple and easy to do
first impressions is very good....,let's see after some time.....
Only played 1 or 2 patches so far but already in love. Enough to make me think of getting recording gear for my phone
This is a really nice app! Unlike most apps everything sounds much more smooth and less like a generic MIDI player.
Hey how you packed such good sounding instruments in so small size . It's really amazing and I love it
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.
If u fixed the connection problem id give 5stars because it is a sweet app im using a samsung galaxy s10 and im trying to use it with my orba2
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.
