Could Be Amazing

The concept is there, but the UI need some work. It said that in the instructions there’s a scroll bar on iPhone, but it doesn’t exist. You can’t really use it on an iPhone. I would gather it. It’s tight on an iPad mini too. On an iPad it’s a bit better and on a Mac it certainly the best. I’m not quite sure why both the keyboard and the synth images don’t default to larger in the first place.

Insane space fusion of 2 synths

Holding up the retro synth inspiration . The 2600 is certainly retro sounding, but really nice. The only crucial thing is to tame that reverb a bit and it’s ace. Perhaps that’s the way the old one sounded but as of right now (April 2o26) it’s just real dense and is maybe overpowering? It’s big and great for drones of course so that is cool. But to me the synth sound shines though with way lighter reverb or much less. Ok so the Midi in AuM is great so far. Pretty big deal. I have not tried midi learn yet.
Updates are well done and it’s pretty much a dream. So fat it just keeps improving, and is a gift from an alien drop pod which is so cheap I thought it was April fools. Nope, it’s real and no IAP even! The other completely amazing thing is the prescription strength circuit bending. You basically get access to the virtual chip and the bends are appear legit (1st I’ve ever seen.)! It of course depends, as typically a bender used sliders/knobs. That would be quite inspiring, but it’s beyond complex as is. Yet understandable in a strange electric vortex of options seeming infinite even with robotic assistance. In general both synths have a nice quality of sound and are quite wild , almost in headphones you may blow up the universe or brain so maybe ‘ponder’ a limiter or compressor.
I like when the inspired retro gear/apps pushes the way into new tones. I think a lot realize it won’t be a clone sonically but the graphics can make it seem that way.
This sounds unique as well, with functionality quite close(without inspection A\B)! Seems like this came from the drop from portal zel along
hyperspace. I’m feeling like a double neck giraffe that woke up with wings. And the app of course.
Much appreciated and the work must have been done out of passion because I’ve honestly you could have charged way more, and made 2 separate ones. Cheers, the only idea I got is an iap of almost anything with custom graphic or knob/sliders.

Great App! but…

This is my first ever review, so this should say something. Fairly new to the ios music making world, but been diving deep. Out of all the synths and music utility apps and daws and auv3, this one has the smallest font. I saw this talked about for a few days in different forum destinations and I heeded the warning but oh, god how right they all were.

The synths sound great, I actually would like to play with them and use them and incorporate into my workflow as I can, but truly impossible with not being able to read anything I’m doing.

I’ve screen all three keyboards, the two in the mod and the toy sampler so I do have an idea now about what all the buttons are but that doesn’t help when in the moment of crafting a sound and trying to find with patch is going to connect to which output.

I truly want to like this app, and I do, like this app but I don’t think any of us can actually use this app until this feature gets figured out. Maybe with an actual zoom feature in app that let’s you scroll very far into the keys and does so smoothly. Or the devs can figure out a way to enlarge the font without sacrificing the intent they were going for in the vision of the app.

This is all coming from someone who has great eyesight, and accessibility zoom feature on, screens shots taken while zoomed in. It shouldn’t be this hard to read the work flow, even at the fiver price point. Small knobs I can do, most apps are featured with that, but small font to the point of unreadable is kind of impossible though, impressive coming from someone with equally small handwriting ;)

iphone - updated to most recent ios - 3.5 stars until this gets sorted.

Other than that, it’s a great sounding synth with fun features and I would like to use them.

A good synth…

…that the devs have made a terrible UI for…
Don’t buy it unless they fix it, so much wasted space, a tiny unplayable keyboard, maddeningly fiddly for no reason..
Hopefully they fix, it could be good, but at the moment it isn’t really useable..
Such a shame…

Arp 2600!

This came from out of hyperspace and dropped a synthetic alien (arp 2600) into portable use. Pretty big deal. Ok, so from the start Its hard to tell how authentic the sound quality is compared to the many hardware versions .I don’t think it has to sound exactly alike, but I hope the patch-points and functions are close enough. So, besides some small quirks/issues, they update and fix it often. I think can only Get better and better as they appear to listen to feedback as well!This is working well at this point, and midi was rolling through AUM great. This is a dream in my world, and I haven’t event touched the other keyboard. Cheers!
