Delia Derbyshire and Karlheinz Stockhausen’s Legitimate Child

I feel like I’m Delia Derbyshire and Karlheinz Stockhausen’s legitimate child set loose with more noise/sine wave tone generators than logically imaginable with this AUv3 plugin inside AUM. Thank you so very much. Would it be possible to allow setting way past 104.858 seconds LFO rate please? 10 minutes would be welcomed.

Some sliders not committing to new values in AU instances

So I’m having issues with this app running as an audiounit. I use cubasis 3 almost exclusively if that is useful info. While triggering auGEN x and adjusting parameters the adjustments will not commit. For example, moving a slider from 143 Hz to 87 Hz immediately jumps back to 143 Hz. Every time auGEN x is triggered the changes that I have made to certain parameters will not stay at the adjusted level. Other that that I like the concept of this app, some of the parameters are slightly cryptic to me. This is sort a strange phenomenon to me because I feel like I am a well seasoned synth tweaker. It’s kind of rare for me to not feel like I understand what is going on with parameters in synth apps. I think I have figured it out and the manual is very good but the icons don’t imply the association’s with the functions to me. ‘Fixed’ ‘Freq Sweep’ and ‘Level Sweep’ are my main issue. This in no way takes away from the app, the only real problem is some of the sliders jumping and unable to commit to new values running as an audiounit.

Response from developer

Hi Obis11, Thanks using auGEN X and thanks for the detailed review. As for the parameters resetting to their original values, you wouldn’t by any chance have any Cubasis 3 automations on them? This would certainly jump them back. Or if you have a MIDI Program Change or Bank Change message, this would also cause parameters to change value. If it’s not one of these, please e-mail us at support@auDSPr.com and we’ll be happy to help figure out what’s going on here. As for the parameter names not sounding so “synthy”, it’s because auGEN X started life as a piece of test equipment so maybe this is why they might sound “testy” instead. Zoinks! Cheers! auDSPr

Complete waste of money

Only “works” as an Audio Unit Extension in GarageBand. Does not work with Inter-App Audio.

Now for the bad news. Can only be used on one track per song.

Now for the blunt truth. This app crashes more than any audio app I have ever used.

What’s more, it is insanely-overpriced (especially considering that it is, essentially, nonfunctional).

Really crummy of the developer to market this as a “cool thing to make weird noises with” [paraphrase] in GarageBand when it is, in reality, an expensive, poorly-made, poorly-designed nightmare.

We’re sorry you’re not happy with auGEN X. Please e-mail us at support@auDSPr.com and so we attempt to help you. auGEN X does not support Inter-App Audio - we never claimed that it did. As for working as an Audio Unit Extension, numerous people have posted videos using auGEN X in AUM, apeMatrix, and Cubasis. Check out our website for examples. For our App Store demo video, we used 5 instances of auGEN X in Cubasis. Please share your crash information with us, so we can understand your issues. It’s curious because we have not heard complaints of crashes from anyone else. Cheers? David Simpao auDSPr

Nice

Nothing like a new and different app, especially when its well done. Even the developer is new to the scene. I hope he continues to release apps because he obviously knows what he is doing. I rarely say anythng about the price of a good app but this one is far from cheap. Is it too expensive? It depends what that means. I bought it despite the price because i was impressed by a review and demo done by someone i think knows more than his own name. I hope the price goes down so that more people can enjoy it.

Thanks the kind and honest review, Perry Pelican! Stay tuned - auGEN X is going to keep getting better! I’ve been catching heat on the pricing, so we’ll have to wait and see how things go. Interested parties will have to follow auDSPr on social media so they know if and when I’m gonna have a flash sale! Even I haven’t decided yet when or if these will happen...

DJ Puzzle recommended this on YouTube

So I’m buying it! Amazing app. Please make it 8 voice poly with detuning! As an AU I’d say one instance for each timbre, and then 1..n voices per instance. I like the way Volt Synth lets you adjust the polyphony.

Amazing first app! Go go go!

Also, is it MMXVIII already? How time flies.

Oh, and an oscilloscope would be killer. I can hook it up the the tek but then I’d have to get off the couch.

I love the enthusiasm @jdubiner! Thank you! And... Thank You, Dj Puzzle! auGEN X started life as an audio test tool, but the community is pulling me to make it a synth — so it looks like that’s where I’m heading! Now, you’ve got me thinking about polyphony... and an oscilloscope. Remember, apeMatrix has a sweet ‘scope. And yes, Volt rocks! Before we know it, it will be MMXIX. Where does the time go? - auDSPr!
