Popsicle is a Multi Effects Processor built around 2 independent stereo effects engines each having access to a total of 24 different effect algorithms.

Effect engines can be used in series or parallel configuration or split between stereo channels where one is affecting the left channel while the other one is affecting the right channel respectively.

Popsicle features a powerful XY Pad capable of controlling one or more fx parameters per axis. XY motion can be recorded and played back in sync with the host tempo allowing for highly dynamic effects.

In addition, a advanced mode unlocks a fully featured mod-matrix with an additional LFO and Envelope Follower allowing for even more dynamic effect combinations and performances.

Included Effects:
- Lowpass Filter
- Highpass Filter
- Bandpass Filter
- Morphing Filter

Great app, but crashes with iOS12

Great app Kai! I love the app, runs fine on my iPad with iOS 13, but it crashes on my other iPad with iOS 12.5.5. Both the standalone and AUv3 crash at launch. I read another reviewer having tge same issue as me with iOS12. So I hope that this will get fixed. The latest update didn’t fix the crash. I already like to give it 4 stars for what it is capable of doing when it works. Looking forward to a bugfix though! Keep up the great work 👍

Popsicle Fx has melted

I don’t want to diss Kia Aras or his apps. I don’t want to overly criticize any developer. I understand how difficult it is to come up with an app from scratch and then deal with Apple. I bought Popsicle FX and it worked until I upgraded my iPad Pro to the latest iOS, 15.4. I expected some of the older, IAA apps to crash, and they did, but one I bought a month ago? I feel strongly about this, mainly because I did a video praising this app, now it is braindead. I tried to contact the developer to discuss this; the contact link on his webpage does not work. I don’t want to leave a negative review, primarily because when this app worked, I loved it. This morning I downloaded the “fix” (for the ancient iOS 12) and of course this didn’t fix the crash issue. So, I either wait for Mr. Aras to address this issue, or I ask for a refund. I simply have too many malfunctioning or now useless apps on my iPad. That’s quite a bit of money. I love working on the iPad, I love touch opposed to a mouse, but it looks like I may go back to Logic Pro. The plugins there always seem to work and the developers usually state what OS version it will work with. With iOS apps, you’re always taking a chance.

Developer Response ,

Hey there,
of course things get tested a lot especially with popular hosts such as AUM but unfortunately not all bugs are easy to catch as they tend to appear only in select cases. That said, the issue in question should be addressed in v1.0.1 which will be out shortly. In the meantime, feel free to reach out via email and we'll be happy to set you up with a beta version.
