What's New

Version 1.5.4

- new "Microtonal scale" feature added as a part parameter with 116 different microtonal scales to select from! Now you can select a microtonal tuning for each part in the pattern individually to achieve interesting inharmonic or ethnic sounds. It is located in the Part menu -> "Tuning" setting. Note: if you wish to play and explore all the steps of selected microtonal scale using onscreen pads, don't forget to set Pattern menu -> "Scale" parameter to "Chromatic".
- minor bug fixes.

Seriously one of the TOP apps of all time!


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.

Amazing pro level app from the dev who made the phenomenal Poison-202 synth! Anything I can say has probably already been said so I’m just going to use this as a platform to beg the dev for my feature requests. 1) the X-Y JimAudio manipulator pad needs to be like 25-50% bigger PLEASE! [erhaps not all the time but for some functions it would work during live play SOOO much better IMHO... Secondly, okay so the people who you’re really making this app for have already invested tons of $$ in Novation’s iMachine-Launchpad-Blocs-, Retronyms AudioCopy, Beatmakers Intua, Sampletank, Beat Hawk, (and a couple more I’m forgetting) sound bank/libraries.. make it a $5-10 IAP +/- but plz be our hero musical savior and incorporate a way to import these sample libraries into groove rider and manipulate them with your terrific program.

Thank you!!!

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.
