It's a great synth app, very flexible and capable of creating a wide range of sounds and soundscapes. It gets 4 stars and not 5 due some glitches. First, in the File menu, there is no delete command, and the Delete button in the File Open screen doesn't actually delete the selected file. Second, in the Node Edit screen, double tapping the value field switches it to Num mode -- tapping it again to edit the value causes the app to crash. Finally, there is no way to enter or edit information about the file. The Information button doesn't work and for some reason the app automatically inserts descriptions from files that come with the app. I hope these issues get fixed. ### 5/5 — Deep and intuitive *2015-02-18, version 1.7.0* This is my favorite app right now. It's very fun to play with, but also seriously capable. I'm still sort of green when it comes to electronic music production and I still have a lot to learn, but using this app is helping me understand a lot of features of the other programs I've been using by having the same tools in an intuitive interface. It's also made some of my other apps a bit redundant, since I can basically create more tweakable versions of them within Jasuto. It's great wether trying to achieve something specific with meticulous detail, or just experimenting with the nodes to see what happens. I only wish I wasn't such a late comer, so I could have grabbed the VST version, which is apparently no longer available. Jasuto is wonderful. Get it. ### 5/5 — Needs update *2014-12-14, version 1.7.0* Good app, but AB not working. Gladly give it 5 stars when updated. Updated 5 stars. ### 5/5 — Classic iOS modular synth revived *2014-07-09, version 1.6.0* Jasuto is one of the older modular synths on iOS, and it was recently (July 2014) revived with an update to add AudioBus and unlock the IAP's that were previously for sale. I found this app very comparable to SunVox, in all the ways that are good and bad. The possibilities with this thing are virtually endless - it can play samples, create tons of synth sound, and do effects. It also added MIDI control, though there are some interesting scale-based keyboards within the app. I do still find that it's a bit intimidating to figure out how to get all of these features to work, but they made a lengthy manual available online. What we really need now is a tutorial video or 10 to really help people discover that functionality. But at the sale price I paid for it, what a fun and excellent modular synth! ### 5/5 — The best app ever, not kidding. *2014-07-05, version 1.6.0* With the last couple of updates this app has become the super app it's always promised to be. I'm so glad it hasn't been abandoned. Audiobus and now midi has made this again the reason I bought an ipad. It is so many things: a sequencer, sampler, synth, modular/math, granular/slicer, and now a midi controller. Just amazing. ### 5/5 — Best modular synth App! *2014-07-05, version 1.6.0* Definetely best modular synth App, last update includes all paid features, thank you so much Chris, I feel in debt with you, gave us much than we paid for, so count with me supporting Jasuto future adds, excellent work! ### 5/5 — Awesomeness *2014-07-04, version 1.6.0* I am brand new to Jasuto, though have played with Audulus. This seems more approachable for a modular synth of this type. Thank you goes to the generosity of the dev, and the thoroughness of the PDF manual. I can see much time vaporizing for me enjoying this app, and that can indeed be a good thing! I will update this once I get to really sink my teeth into it. Talk about an app awaking from a long slumber full of fresh energy! ### 5/5 — My New Best Friend *2013-12-07, version 1.5.0* I have a few of the modular synthesizer-type apps. This one has become my new favorite. It seems very intuitive to me. And you can learn a lot about modular synthesizers and signal paths. Or at least I'm learning a lot. I guess I don't know about you. But for me this was worth every penny and I bought all of the IAP. I think the main thing I have to be careful of with this app is I could end up playing just this, or at least just this through all kinds of Audiobus filters and effects and loops. Very addictive. ### 5/5 — Deep, great sound, amazing potential! *2011-12-29, version 1.3.2* Not for the faint of heart, but really deep synthesis. Makes most other music apps seem way overpriced. Controllers are the one area where more sophisticated modules would be good. The keys module is fairly Spartan. It would be handy to be able to create a custom controller that controls several parameters sent to several modules while also controlling pitch. ### 5/5 — Amazing *2011-11-16, version 1.3.2* I bought this app over the weekend and I am hooked. The quality is outstanding - the interface is beautiful and it hasn't crashed on me once. There are many modules so a great deal to explore. As my brother told me, make sure you have a speaker node or you won't hear anything! ## Most critical reviews (10 lowest-rated) ### 1/5 — Jasuto *2023-10-18* Why did I get a privacy warning when I tried to open the manual? It worked fine on my old iPad but won’t do anything on my iPhone. ### 1/5 — Oh No! iOS 11 No Go! 🙀 *2017-09-28, version 1.7.0* Edit: hoping this gets upgraded to iOS 11 (64 bit)... ________________ Original review: Holy Amazecow! First off: cannot believe I waited this long to try Jasuto. Modular creaminess galore. Does loads of things - drum synth, sequences, fx, pads, self-generating ambient 'scapes, very thick sexy basses, and once you get used to the kind of weird but efficient workflow it's really easy to tweak stuff simply by moving the modules around. I have almost every other modular available for iPhone, but can already tell this is going to be more fun and sonically rewarding than the rest. Just... WOW. ### 1/5 — Dev hit by a bus? *2017-04-18, version 1.7.0* So sad, another set of apps left to rot. Always a risk with mobile, especially with single-dev apps I suppose. ### 1/5 — Welp, looks like it's over *2016-01-21, version 1.7.0* This project is dead. RIP Jasuito. So sad an excellent project went to waste. Hasn't seen updates or bug fixes in a while. The website is iffy at best. My recommendation is to go buy Zmors modular but basically just look elsewhere. ### 1/5 — Refund! *2014-12-28, version 1.7.0* It simply does not work. The app does not open. I've tried deleting it and reinstalling, but still nothing. I gave the App Store my five dollars, and I got nothing in return! ### 1/5 — Great app except Audiobus *2014-11-19, version 1.6.0* Ok it's been well over a month and no update. Audiobus does not work at all so don't believe that it will. Why keep selling the app if you are not going to continue it? Update:: website is back up. But no update to the fact that Audiobus no longer works. I bought Audiobus just to use with this app now I am out a few dollars. I wonder how many more people are also out the money? ### 1/5 — Ahhhhhhhhhhhhhhhhh!!!!! *2014-04-29, version 1.5.0* Ok, generally I like noodling for notes, but this frustrating gadget is only for the pen protector crowd, people willing to push little circles around for three hours just to make one screechy sound. There are hundreds of apps that do the same thing with one one hundredth of the time--which saves you some time to create music. Also, in spite of the fact that you can't record without "buying" record, they nonetheless trigger the red bar at the top of your iPad that you are recording, which you're not. But it stays up there for the remaining lifetime of your iPad--unless you delete, because they don't tell you what arcane command makes it go away, which in my case is ok. I figured it out: delete! ### 1/5 — I want to love it, but it crashes every time I open the app *2010-10-21, version 0* I am running ios 3.2.2 on my iPad. This was just made into a universal app. Correct? Why does it crash after about half a second if the jasuto logo coming on screen? Further more. It worked great before the last two updates. Frustrating. Yes I have rebooted my iPad and done a hard reset. This is getting ridiculous. Please fix this bug. ### 3/5 — Very little, way too late. *2019-06-19, version 1.8.0* Update: When this synth app was first released it was a marvel. But there it pretty much sat for years and years, falling behind standard technologies, existing in an apparent vacuum, slowly becoming ‘odd man out’. Being ‘only’ designed for AudioBus greatly cripples it’s usefulness. Now that I’ve switched from AUM to apeMatrix there’s no looking back. No IAA, no AUv3, no Ableton Link, etc. It’s a shame as Jasuto had a good PDF manual. I’ll leave it at 3-stars, for now, in hopes that this developer will bring Jasuto into modern times. —— I think I missed the 64-bit update, having deleted Jasuto since it wasn’t working any longer and ‘appeared’ to be no longer supported. I was searching on ‘synth’ looking for anything new and stumbled across Jasuto. I about did a summer-salt downloading it immediately. Jasuto was the first synth app I ever owned. It’s a little disappointing though that Jasuto doesn’t support IAA, Ableton Live, etc., so it sorta is a novelty app for now. It is a cryptic comment by Chris. According to his Jasuto manual He joined Apple in 2008. He’s picking up on something from 11 years ago? Good PDF user manual. ### 3/5 — Intriguing, with possibilities, but needs manual *2012-02-27, version 1.3.2* This appears to be a very powerful tool for exploring sound design. It is very robust, with many features, but desperately needs a good user manual. There are some materials available but they fall far short of a good instruction manual. ## Most praised reviews (10 highest-rated) ### 5/5 — Yay! *2019-03-25, version 1.8.0* yay. ### 5/5 — It’s baaaaack!!!! *2018-08-24, version 1.8.0* Super powerful app. I’ve Hardly scratched the surface and already creating weird and wild sounds. No need to be a programming genius to git this bugga shimmering. Considering the depth of this thing I will be immersed for some time. ### 5/5 — Grin a mile wide : 64bit! *2018-08-24, version 1.8.0* This update is a wonderful surprise! Thank you for taking the time to ensure this wonderful piece of software can live on for many more years (hopefully). 128-bit isn't going to be required next month, is it? Curious about your cryptic comment : 'priority to what [you] were working on prior to joining Apple'??? ### 5/5 — Jasuto Lives! *2018-08-23, version 1.8.0* I can't think of a modular iOS app that I've used longer than Jasuto. It's definitely fiddly, but you this thing can do simple synthesis all the way through building a vocoder. Highly recommended, especially if Chris keeps adding to it. ### 5/5 — wow 2018 update!! *2018-08-22, version 1.8.0* Thank you baby jesus!!been waiting years for an update fir this awesome app!!!!! ### 5/5 — Amazing modular synth updated to 64 bit! *2018-08-21, version 1.8.0* I never write reviews, but I had express my joy and admiration to the Dev for updating to 64 bit! Jasuto is one of the most powerful modular environments around (FFT analysis and spectral effects) but with an amazing design focused on the fact that this is running on a touchscreen platform. The distance between nodes affects their modulation strength, so you can "play" your scenes - and, even better, with motion recording, those modulations become complex LFOs. No idea if the Dev will have time to add in modern features (Ableton Link, AUv3, etc.), but regardless, this is still amazingly capable after all these years (and with FFT and motion recording more capable than other, more recent, options) and well worth adding to the collection of any audio explorer. ### 5/5 — iOS 12? *2018-05-20, version 1.7.0* Any chance we might see a version compatible with iOS12.. really missing this app. Don’t want any new features just to be able to use it again! ### 5/5 — Love this app. Any chance of an update? *2017-07-30, version 1.7.0* Takes some real effort, but what an instrument! This is a deep application. Best synth app by far! Im using this app on my record! Totally amazing sounds! Bravo!!! ### 5/5 — Really good *2015-07-03, version 1.7.0* Way better than the logo or screenshots would lead you to believe. I downloaded on a whim despite owning several other modular apps, but this is my fave. ### 5/5 — The best *2015-06-29, version 1.7.0* Jasuto is easily the best balance of raw power, flexibility and ease of use to be found in iOS land. I'm sure it's very difficult to remove all bugs from software this complex, but in the current iteration Chris has done a great job of getting rid of all the glaring usability issues that plagued earlier versions, and this app now fulfills all the promise that was there in 2009. While not for the faint of heart or the rompler-lover, Jasuto is a serious tool for noisemaking. It's an invaluable learning aid for those thinking of getting into hardware modular; most techniques used in Jasuto are directly applicable to that realm. Still great after you own hardware as a sketchpad for your patching ideas, or just to keep up your chops wherever you're at. To get such limitless power in hardware...I'm not sure $50k worth of Eurorack would be able to match this app running on any iPad or iPhone you can buy right now. In a couple years it might take $100k. Seriously. You want 30 oscillators? 14 filters? 6 different delay lines? A dozen envelopes? No problem! Get out your wallet and keep funding this guy, because I want more! More! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
