Looks like this developer decided to adopt a subscription pricing scheme on an already overpriced app. But now you can’t even preview the program templates before you buy which is exactly why I decided against purchasing.

I was about to buy the Mopho, volca fm, and jd xi program interfaces (used to be $20 and is now $30!! Lol) but I’ll look elsewhere as there are plenty of reasonable alternatives with better GUI and free (lemur, max4live, okdev for the jd xi which is free).

I realize I could subscribe for a month and get all the templates for less but I would rather invest my time and money into something I plan on using long term without being billed monthly. If the pricing was reasonable like $10 per synth I probably would have bought all 3 even without being able to demo before buying like before the update and like the website claims you can do. 👎👎



This app is handy to have for the Volca FM; it provides a mobile solution for patch storage and management, but it’s overpriced for what it is. It has multiple issues, and for $20 these issues are unacceptable. If I pay that kind of money for an app, it better operate near flawlessly. The issues I have noticed are:

-When you import DX7 sysex files for the Volca FM editor, operators are always turned off at random. You spend a large amount of time going through and turning operators back on, anywhere from no to all operators. However, it is very rare that you come across patches with all operators on.

-When you try to load certain patches, the app crashes. You can’t open the patch at all, so you are unable to access the parameters or the voice.

-When you unzip folders to access the individual sysex files, sometimes the app will freeze and you have to close and reopen the app.

To be clear, I have both an iPad Air 1 and iPad 2, and the app behaves the same way on both iPads. If I paid $5, I may not have as big of a problem with the issues I’ve come across, but for $20, the developer is charging too much for a single editor on this app.

Hi, sorry about the crashing bugs. If you'll get in touch with me via the in-app support or my website we can get those bugs fixed. I'll be happy to take a copy of the problem patches.

As for the issue with operators being turned off when you import a DX7 patch to the Volca FM, it's not random; the DX7 doesn't store information about whether an operator is on or off. The Volca FM *does* store that info, and it stores that info in the place where the DX7 stored a checksum value. So when you import a DX7 patch, the Volca reads that checksum as operator on/off data. I could make the editor ignore that info and turn all operators on, but then that would interfere with some Volca patches that *do* want some operators to be off. I figure it's easy enough to tap the "On" boxes after you import a patch... it doesn't seem like that should take much time. Just tap a few boxes. If I can think of a better solution down the road, I'll improve it. Also always open to suggestions.


Pricing is bonkers

It makes sense to offer each synth on its own as people are very unlikely to have all or even most of these synths, most people will have one or maybe two, but to price every synth at $20 makes no sense at all. A $20 app to help with a multi thousand dollar synth makes sense, a $20 app to help with a $150 synth like the Volca FM is crazy. I feel like this was a super short sighted move by the developer that will lose them sales rather than make them money. I’m sure 10x people would grab that if it was $4.99.

Edited review down to 1 star after the dismissive comment by the developer. Completely missed the point while patting himself on the back. Lame.

Developer Response

Hi Sean. I try to strike a balance between an affordable price for customers, and a price that can continue to support the development of an app that is for a rather niche market of users!

I don't believe that looking at the price of Patch Base as a percentage of the price of the synth itself is the best way of seeing it. Speaking to your example: Part of the reason the Volca FM is a cheaper synth is that Korg took a very powerful FM synth engine and put it in a box where it's next-to-impossible to program that synth engine! So, you can look at Patch Base as something that adds a lot of value (the ability to program the synth) to a cheap synth that doesn't have that ability. For the price of the app, your Volca FM becomes something closer to the Yamaha DX7, but for a fraction of the price. From that perspective, Patch Base is a great deal, and many customers have recognized it as such.

I appreciate that you don't agree with the pricing, but I hope you'll understand my perspective, and perhaps rethink your review, which doesn't speak to the quality of the app itself, but rather only your frustration with the price.
