Seriously one of the TOP apps of all time!


Argh! Why did the App Store wipe out my previous review! Oh well, you’d have thought I was paid to write it anyway ... it was that glowing.

This app is utterly fabulous, and this developer is amazingly responsive. Feature after feature has been added every week. Groove Rider 16 is a groove box. And it is so feature rich, well designed, and just plain fun to use that I can’t put it down. All my iOS DAWs seem like work rather than play. This is mainly designed around 4-bar patterns, so take the reviews saying this is a full fledged music production system, the best DAW ever, etc. Sure, you can make songs by chaining patterns together, and can export patterns into DAWs, but it’s main attraction for me is as a quick and fun jammin’ idea powerhouse.

That said, it has HUGE power under the hood. A good library of samples included, the ability to import your own, and a surprisingly good synth, that is super-basic, but able to dial in great sounds in a fraction of the time I spend messing around with full synth apps. Did I say synth ... I mean up to 16 of them if you want.

At the very least, consider this an introduction into the best features of high-end hardware groove boxes at a tiny fraction of the cost. If it doesn’t gel with you ... then you just saved yourself hundreds of dollars on hardware, cause you won’t like it either.

Dude:Seriously? OF COURSE!

K, really dude..?! Where has THIS been my whole life!
If you have Poison 202....then YOU know not to expect anything less from the sonic genius and ability of Dmitrij. Gorgeous, User friendly, simple and sonically vibrant,... I am one happy soft synth enthusiast. My 10 bucks was NOT wasted, and man am I stoked about the potential for Live use outta this thang. I DO have two simple requests though... please in your next update, include more ‘instruments’, and more important: please find a way to make it easier to lock-in on non-decimal values when changing/re-tuning a sample’s pitch. The Oscillator’s pitch control is a littttttle sensitive. Just an idea, but maybe think about replacing the knob control with a Fine and Course tune-setting. But man am I excited to take some more time with this baby, thanks Dmitrij, you are a superior sound designer and whoever does your graphic design is quite impressive as well!

Ohh This Is Going To Beee Fun❣️


I'm going through the setting, turning on background play, etc., and probably will be playing with this till sunrise. I can feel it❣️ My Christmas present to me. 🤓 Thank you Dmitrij❣️ I stopped reading when I saw that it used the Poison synth engine and bought it. It became a no brainer, it did. It wasn't that it was 50% off. lol (and that I saw that the filter was a 12/24 dB / octave. I'll come back for the rest.

This, THIS is going to be good. A lot fun. Dmitrij these (and Poison) are like what I would put together with the exact same features if I was so gifted. I had been wishing for something that was both a 'mad synthesizer' but it was hidden under a bigger musical personality. Be back with results of my initial impressions.
