The first half of the oscillator is represented by 32 blocks and the second half is its mirror, generating all sorts of possible raw retroish sounds. 16 pages per oscillator allows to interpolate between different shapes. Add effects like arpeggio, stereo delay and a resonant filter and record your sounds on a classic tape. Modulate any parameter with keyboard, MIDI MPE or the device accelerometer. Connect to other apps with AudioBus, IAA, AUv3 and midi. +++ 16 voice polyphony +++ 2 oscillators, draw your own shape +++ 3 oscillator mixing functions (add, subtract or multiply) +++ Lfo modulation with ADSR: envelope, pitch, duty cycle, square, page or filter +++ Record on tape with infinite overdubs (save, load, import, export) +++ Arpeggiator +++ Stereo delay +++ Resonant filter (low, band and high pass) +++ Modulate any parameter using keyboard, MIDI MPE or accelerometer (Built in or Sphero) +++ Mini linear sequencer with euclidean rhythm +++ On screen 25 key stylophone style keyboard +++ AudioBus, Inter App Audio and AUv3 +++ Ableton link or AUv3 host sync +++ CoreMIDI, IAA MIDI, Bluetooth MIDI, limited MPE and MIDI out +++ Audio Paste, files app drag’n drop or open with ## shapesynth Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/39/a2/68/39a26824-73b3-ee68-c424-09efc724d5cd/mzl.xdamwtsl.png/960x640.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/83/ef/86/83ef8616-986c-8b0e-f81e-baa1f2b3224d/mzl.aofculca.png/960x640.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/Purple113/v4/dd/87/46/dd87465c-6837-2707-c660-857083858076/mzl.nhbvrcna.png/960x640.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/a7/3f/6d/a73f6d7d-0018-1607-8705-ef590377b1e5/mzl.ckvjhmyi.png/960x640.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/Purple123/v4/a8/e5/3c/a8e53c09-6635-d440-588a-e8ff9322a9c0/mzl.gmwxyedh.png/960x640.png) ## shapesynth Rating Breakdown in United States - 5 stars: 21 (95%) - 4 stars: 0 (0%) - 3 stars: 1 (5%) - 2 stars: 0 (0%) - 1 stars: 0 (0%) ## shapesynth Reviews in United States ### ***-- "Disappointed" Was expecting to get evolving SoundScapes. Instead, all the app seems to produce is variations on a theme. -- Jackster847, 2023-08-22 ### ***** "Nice Update and now AU!" Glad to see this go AU. Get all of this devs apps. They are excellent! UPDATE 11/2018: The controls are somewhat cryptic but once you know what they do (as the on-screen hints indicate) you will find these are very cool apps. This update makes this much more fun. Nice crazy sounds. Get it! -- anickt, 2019-12-14 ### ***** "Erik The Great does it again!" First class updates to a first class app from a first class developer. Get them all! What are you waiting for? -- Ben Efitofadoubt, 2017-06-01 ### **--- "Snap Crackle Pop" Absolutely love the concept here, but I'm getting all sorts of crackling static sounds when playing any note. Tried closing all other apps and it still crackles. I'm using an iPhone 6s. Can you fix it Erik? -- Motor D, 2016-11-17 ### ***** "Unique" I love Erik Sigth a.k.a. Humbletunes' apps. Imaginative, inexpensive, innovative and like nothing else on iOS. Buy them all. -- Philowerx, 2016-08-17 ### ***** "Allows you to create some rich sounds." This update makes it a lot of fun to experiment and make sounds that are extremely good for such a low priced synth. Very cool interface. -- Synthmd, 2016-03-26 ### ****- "Erik's update makes it a whole new app" Erik Sigth's apps are some of the most unique iOS music production tools around. They all have a GUI that admittedly one likes or doesn't like most of the time. If there are indicators to what a control does or at least a manual or help (?) option I don't mind the layouts. Thing with the old version of the shapesynth was trying to make patches while using such a bare interface did cause problems. Now that things are labeled and laid out better, the synth is a joy to play. And a totally unheralded aspect of this synth is the brilliant recorder. For an old analog dude who learned on Tascam PortaStudios there is the joy of seeing the little tape graphic and some of the more tape oriented controls. The real use of the recorder should be explored, most synths get AudioBussed or AUMed out to a DAW like Auria or Cubasis, this recorder can allow you to make some cool experimental soundscapes and then manipulate them further on in a DAW or app like Samplr. Just a great app for under $5 and incredible at just $2. -- JRSIV1975, 2016-03-25 ### ***** "shapesynth comes full circle!" Sonic possibility abounds inside this app, all wrapped in a more user inviting environment. Highly recommended for those with a sound affinity. -- WendysFrostyCarlos, 2016-03-25 ### ***** "Awesome Update!!!" I always loved the sound of Shapesynth, but could never wrap my head around the minimal and confusing interface. But this update basically restructures everything--it's virtually a new app. The developer has grown and grown, I think. His more recent apps like Elsa and Strng are brilliant, and I think all that experience has been applied to reinvent Shapsynth! So nothing but mad props from this girl! 😊 -- SynthyMiranda, 2016-03-24 ### ***** "I love Shapesynth" From the get go I dig this instrument. It is fun, inspiring and just PLAIN COOL. I am thankful for it and also NILS - Humble's awesome effects processor. With Shapesynth I have a blast with its syncing LFO's, delays and just total uniqueness. The fat sound it emits is very playable and as I've said (too much) in other reviews I LOVE A MINIMALIST GUI that harnesses a tremendous sound. This app is like no other and truly is a favorite of mine. Thanks for designing it! -- Mo Freeapps, 2013-10-25 [View all shapesynth reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## shapesynth Available In - [United States](https://apptail.io/app/shapesynth-Wxwe/united-states) - [United Kingdom](https://apptail.io/app/shapesynth-Wxwe/united-kingdom) - [Germany](https://apptail.io/app/shapesynth-Wxwe/germany) - [Canada](https://apptail.io/app/shapesynth-Wxwe/canada) - [Japan](https://apptail.io/app/shapesynth-Wxwe/japan) - [Spain](https://apptail.io/app/shapesynth-Wxwe/spain) - [Italy](https://apptail.io/app/shapesynth-Wxwe/italy) - [Sweden](https://apptail.io/app/shapesynth-Wxwe/sweden) - [Greece](https://apptail.io/app/shapesynth-Wxwe/greece) - [Denmark](https://apptail.io/app/shapesynth-Wxwe/denmark) - [Austria](https://apptail.io/app/shapesynth-Wxwe/austria) - [Russia](https://apptail.io/app/shapesynth-Wxwe/russia) - [South Africa](https://apptail.io/app/shapesynth-Wxwe/south-africa) - [Norway](https://apptail.io/app/shapesynth-Wxwe/norway) - [Switzerland](https://apptail.io/app/shapesynth-Wxwe/switzerland) - [Egypt](https://apptail.io/app/shapesynth-Wxwe/egypt) - [Romania](https://apptail.io/app/shapesynth-Wxwe/romania) - [Finland](https://apptail.io/app/shapesynth-Wxwe/finland) - [France](https://apptail.io/app/shapesynth-Wxwe/france) - [Australia](https://apptail.io/app/shapesynth-Wxwe/australia) - [Netherlands](https://apptail.io/app/shapesynth-Wxwe/netherlands) - [Ireland](https://apptail.io/app/shapesynth-Wxwe/ireland) - [Israel](https://apptail.io/app/shapesynth-Wxwe/israel) - [India](https://apptail.io/app/shapesynth-Wxwe/india) - [Jamaica](https://apptail.io/app/shapesynth-Wxwe/jamaica) - [South Korea](https://apptail.io/app/shapesynth-Wxwe/south-korea) - [Kuwait](https://apptail.io/app/shapesynth-Wxwe/kuwait) - [Kazakhstan](https://apptail.io/app/shapesynth-Wxwe/kazakhstan) - [Lebanon](https://apptail.io/app/shapesynth-Wxwe/lebanon) - [Malta](https://apptail.io/app/shapesynth-Wxwe/malta) - [Mexico](https://apptail.io/app/shapesynth-Wxwe/mexico) - [Malaysia](https://apptail.io/app/shapesynth-Wxwe/malaysia) - [Nigeria](https://apptail.io/app/shapesynth-Wxwe/nigeria) - [New Zealand](https://apptail.io/app/shapesynth-Wxwe/new-zealand) - [Peru](https://apptail.io/app/shapesynth-Wxwe/peru) - [Philippines](https://apptail.io/app/shapesynth-Wxwe/philippines) - [Pakistan](https://apptail.io/app/shapesynth-Wxwe/pakistan) - [Poland](https://apptail.io/app/shapesynth-Wxwe/poland) - [Portugal](https://apptail.io/app/shapesynth-Wxwe/portugal) - [Saudi Arabia](https://apptail.io/app/shapesynth-Wxwe/saudi-arabia) - [United Arab Emirates](https://apptail.io/app/shapesynth-Wxwe/united-arab-emirates) - [Slovenia](https://apptail.io/app/shapesynth-Wxwe/slovenia) - [Thailand](https://apptail.io/app/shapesynth-Wxwe/thailand) - [Türkiye](https://apptail.io/app/shapesynth-Wxwe/turkey) - [Taiwan](https://apptail.io/app/shapesynth-Wxwe/taiwan) - [Ukraine](https://apptail.io/app/shapesynth-Wxwe/ukraine) - [Uzbekistan](https://apptail.io/app/shapesynth-Wxwe/uzbekistan) - [Singapore](https://apptail.io/app/shapesynth-Wxwe/singapore) - [Armenia](https://apptail.io/app/shapesynth-Wxwe/armenia) - [Argentina](https://apptail.io/app/shapesynth-Wxwe/argentina) - [Azerbaijan](https://apptail.io/app/shapesynth-Wxwe/azerbaijan) - [Belgium](https://apptail.io/app/shapesynth-Wxwe/belgium) - [Bulgaria](https://apptail.io/app/shapesynth-Wxwe/bulgaria) - [Bermuda](https://apptail.io/app/shapesynth-Wxwe/bermuda) - [Brunei](https://apptail.io/app/shapesynth-Wxwe/brunei) - [Brazil](https://apptail.io/app/shapesynth-Wxwe/brazil) - [Belarus](https://apptail.io/app/shapesynth-Wxwe/belarus) - [Chile](https://apptail.io/app/shapesynth-Wxwe/chile) - [China](https://apptail.io/app/shapesynth-Wxwe/china) - [Colombia](https://apptail.io/app/shapesynth-Wxwe/colombia) - [Cyprus](https://apptail.io/app/shapesynth-Wxwe/cyprus) - [Czechia](https://apptail.io/app/shapesynth-Wxwe/czechia) - [Dominican Republic](https://apptail.io/app/shapesynth-Wxwe/dominican-republic) - [Algeria](https://apptail.io/app/shapesynth-Wxwe/algeria) - [Ecuador](https://apptail.io/app/shapesynth-Wxwe/ecuador) - [Hong Kong SAR China](https://apptail.io/app/shapesynth-Wxwe/hong-kong) - [Hungary](https://apptail.io/app/shapesynth-Wxwe/hungary) - [Indonesia](https://apptail.io/app/shapesynth-Wxwe/indonesia) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
