It’s serverely unstable for me - both stand-alone and in AUM. (But lets not derail the thread!
)
Very easy, just drag and drop the files in the Wavetables manager (available on the hamburger menu top left)
Thank you! And this clarifies something - Oscidia can load Serum wavetables!
There is a nice write up on Synth Anatomy: https://synthanatomy.com/2025/08/4pockets-oscidia-advanced-wavetable-synthesizer-plugin-for-ios-and-macos.html
It’s definitely something on my wish list . I’m gonna have to wait a good while (was already having financial difficulties due to my health starting to decline , and now I’m with my wife at the hospital after car accident) but I’m definitely getting this when I can
I have problems with the Mod Matrix. 100% Modwheel on filter frequency has only minor effect. I haven’t been able to create an MPE preset. It looks like a bug.
For me, it's top 2025 iOS synth (so far)
Got awarded an Apple giftcard from my job for performance and picked this up …and yeah I’m digging it !
There was a bug that meant aftertouch wasn't working, but that got fixed (aftertouch needs to be on in settings of course).
The reason you're getting only a minor effect from pitchbend is that you need to also open the env amount knob in the filter section. This controls how far any filter modulation can actually open the filter. Turn it all the way to the right. As long as you do that, cc74 filter automation will also work as you expect. Just assign cc74 to cutoff in the matrix. For mpe control of amplitude, assign cc74 or aftertouch (depending on your preference) to feg 1,2 and 3 in the matrix. Make sure MPE mode is turned on in settings.
I did a few videos about mpe in this on my Patreon BTW. 4 Pockets really needs to explain more in the manual about the mpe settings, I reckon the majority of users will think there are bugs because it's not explained sufficiently. Would also be good if there were some proper mpe presets.
Congratulations man. glad you got recognized, and glad you get to experience what I think is one of Paul's best synths.
Thx @Gavinski for covering the MPE update
thank you @Gavinski for your help. I knew Oscidia is well thought out, and that it was on my part why the modulation didn’t work as I expected. I read the part about the mod matrix in the manual.
Something tells me that Oscidia is a very good MPE synth.
This sounds very good, and pretty intuitive to use.
Thank you …and yeah it’s incredible
@Nighur Thanks for the tip, I was looking for such information
It is useful when using Oscidia in Garageband with on-screen keyboard.
I compared size of the 4Pockets interfaces in Garageband and it looks like this:
4Pockets - Oscidia "default" (38% of the screen width)
4Pockets - Oscidia "allow full screen mode -> OFF" (76% of the screen width)
4Pockets - EvolverFX, Chameleon (88% of the screen width)
76% is not as comfortable as 88%, but now is usable with the on-screen keyboard, exactly 2x larger interface than the default one.
This is my absolute favorite synth and a banger of a deal for 7.99
Between this, ElasticOSC, Vital, and @Rob_Jackson_Music's buttload of offerings- my world is sounding a lot better rn.
I’m saying anyone who hasn’t got this Mr.Paul @4pockets_paul knocks it outta the park & @DMTcymatics dropped some inspiring presets in there for free…FREE… at 7.99 it’s a no brainer.
I think Oscidia is a fantastic synth and a deal for the price, however it's using more processor than I would like at least for some projects. I'm seeing it using around 25-30% with just some simple MIDI input driving it. If I replace it with Chameleon in the same slot in AUM, that consumes around 5-7%. Is anyone else seeing it using resources at that level?
Check if the high CPU presets from Oscidia are using multiple wavetable oscillators, check the polyphony, release times on pad sounds etc as these can all ramp up CPU considerably.
Whoops just got this … latest AUM beta. Will let @4pockets_paul know.
@ craftycurate - It was a couple of the factory presets. I’ll check those out details and see if there’s a patern.
Thanks 👍
I really appreciate that you can remove the background image (@Edward_Alexander), I've said it before: it's nice art but not there. Long-press on the 'Main Menu' button to get that and some other variations.
Wavecloud from same dev has this issue too (only very occasionally and in ways that are hard to replicate)
I purchased Oscidia on Friday after watching Doug demonstrate it on the SoundTestRoom, he started by saying just listen to this one note, it’s classic VANGELIS he was right, the rest of the presets are pretty awesome too, especially using the vast amount of wave tables to create some fantastic sounds, very well worth buying, it’s on half price sale until Wednesday 26 November 👍
Mike.
I'm not sure where to report bugs for @4pockets_paul apps. I found the same bug in both Oscidia and RingsFX (maybe more, but those are the only 4pockets synths I have).
If you hold down a midi note, and then send the same note again, the note will get stuck and you have to panic out. Happens every time.
I found this by using Harmonicer to constrain my midi keyboard to a specific scale. When you do that, the out-of-scale keys get remapped to in-scale notes. So some keys end up sending the same note. And then if you hold one key, and pres another key that sends the same note, the note gets stuck in the synth. Its very easy to trigger while playing.
@DePingus - You can try [email protected]
I'vd tried a couple of times regarding an issue in Surface Builder, and never received any response. I'm told he can be reached on FB, but I abandoned that platform long ago, and I think it's not a good idea to make that one's primary support contact.
He keeps putting out new (usually really interesting) apps, and even updates for them, but seems to have no time for or interest in actually revisiting older work and considering feature changes.
Which is not a heavy-handed criticism, but a frustration. I like his apps, and want to keep using them.
@garden - Understood. I would recommend trying again, since Paul has had some issues with his health and more recently with care for his family in the last couple of years, which has been communicated here and there. I’ve had contact with him over various bugs and feedback over a few years, and I always use email, and I’ve had to follow up a couple times, and in some cases it took a while to reach him, but he’s usually comes through. Not trying to argue, but he has made updates to many of his older apps to support iOS 26, but yes, the feature updates do seem fewer - he was on a real tear with Helium, Neon, and later, Midistep with a flood of new features a while ago. Of course at the end of the day its up to every individual to decide what they need from the app and the developer.
I happen to be a longtime 4Pockets fan, and feel a real commitment to the apps and the developer and try to do what I can to provide helpful information on using some of the apps and share it with the community, so that”s where I’m coming from.
Thanks for all the info. I will try the email and see what happens. I don't think this bug a huge deal breaker, as it only triggers under a very specific use case (when playing with some kind of scale mode enabled). I have several of Paul's other non-synth apps and think they're pretty great. Going by the update history on the app store, he seems to release updates for most of them regularly. So hopefully a fix for this will eventually find its way into an update.
Fwiw, you could put a streambyter or mozaic between the midi source and synth and either filter out the duplicate pitches or make sure a note off precedes the duplicated note on.
UPDATE:
I wanted to add some more data to my email, so I did some more testing. I brought out my Novation 49SLmk3 keyboard, which has a scale mode. Using they keyboard's scale mode, Oscidia works correctly. So I slapped MIDISpy in between and started digging.
With the keyboard in scale mode, MIDISpy sees 4 midi messages: Note On, On, Off, Off. Which is how I played the offending keys. When I put MIDISpy on Harmonicer, it only sees 3 messages: Note On, On, Off. Which is probably why the 2nd note gets stuck. There's a missing Note Off.
So, this looks like a Harmonicer bug. I guess not all iPad synths handle Note Off messages the same. Trooper, Shaper, and J6 don't have a problem with the missing Note Off. But Oscidia, RingsFX, and PhaseMonkey do.
I'm gonna skip the email to Paul and try to contact the Harmonicer dev instead. Thanks again everyone who chimed in!
