What's New in pUnKGeN

2.4

May 30, 2025

Updated UI, mostly for easier text to read on iPhone. Minor fixes.

User reviews

Completely unusable

Looked interesting but only about half of the interface elements work and if they do they don’t make any difference to the sound produced. I would have thought that Apple would check the functionality of apps before adding them to the store.

MIDI just doesn’t work

Ok it took a while but I got the MIDI working. I had previously rated lower because IAA MIDI routing can take a bit of figuring out. The app is kinda clunky and a bit noisy, but that’s very punk so I’m here for it.

Wasted Potential.

The app itself is not bad at all and can be quite fun but unfortunately it has a big problem loading in other hosts. In AUM it somehow only shows up half the time and is nowhere to be found the other half. And even when it shows up it won’t load, just instant crashes every single time. In Audiobus 3 it launches the devs other FM app instead, despite me loading this exact app. When I close the other app and retry, it instantly crashes as well. Have contacted the dev and they said it’s working for them somehow so not expecting a fix.

All in all, if you want a standalone only app it could be great but if you’re like me and bought it to use with other apps and in other hosts, you may be out of luck.

Potentially awesome sound machine

Unfortunately I can’t get MIDI to work as expected and there doesn’t appear to be some way to select scales and modes except thru random generation. Which means the app doesn’t play well with others. Was so looking forward to this.

London calling?

I’ve been trying to review this app since it was released, but for some reason Apple keeps disappearing those reviews. So, one more time… PunkGen is a great idea, with lots and lots of potential, as the deliberately uncouth cousin to Riffler (the guitar app, not to be confused with Riffer), spewing out sounds that could have come from the Punk Rock era. The problem, is that it is not (yet) possible to fix a key and scale. So what you get is literally a roll of the digital dice. But to be of use in a workflow key and scale are controls are required.
