Groove Rider GR-16 is a professional step-sequenced groove box, inspired by professional hardware drum machines and rhythm boxes. It has a powerful Poison-202 based two oscillator synthesizer engine, plus a big variety of included PCM drum samples, insert/send/master effects, arpeggiator, automation recording, modulator, ADSR and filter block, and more! Built-in factory pattern library includes patterns in different music styles, which will inspire you (the list will be appended with the regular updates).

Groove Rider GR-16’s Engine – When High-Quality Synthesis Meets Samples 

Groove Rider’s engine features two main architectures: a high-quality synthesis and a sample engine. A source can be either a Synthesizer engine generated sound, or a PCM sample, internal or external (imported by user). The synth part is based on the excellent Poison-202 engine and features two oscillators.

Than the signal is routed to a filter block that includes several filter types (low-pass, band-pass, high-pass, peaking-filter or notch). Users can here choose between 2-pole or 4-pole versions of each filter, as well as simple filters and soft-clipped filters with more smooth and compressed sound in high resonance range.

The modulation section of Groove Rider is compared to other available Synthesizer groove-boxes massive. An extensive modulator block is located right next to the filter section and includes 9 different modulation waveforms per part: Envelope Generator Up/Down, Triangle LFO, LFO BPM-synched, Saw up/down, Square up/down and Sample&Hold. Users can assign part’s modulator to control one of 6 destinations: Filter, Pitch, Level, Pan, Oscillator parameter or Insert FX parameter. This allows musicians to create complex sounds very quickly.

Right next to the effects, an envelope section is available with a simple ADSR envelope generator. This can be routed to the amp or/and to the filter cutoff. All this is rounded up with a massive amount of high-quality on-board effects. Groove Rider features 34 different effects as insert effects with dedicated parameters for fine adjustments. It includes: reverb, chorus, flangers, phasers, mono & stereo delays, filters, distortions, decimators, vinyl break, slicers & more.

To get an excellent overview over your 16 parts tracks it features also a straightforward mixer page with all essential features of modern mixers (pan, mute, send FX, limiter…)

A Rhythmic Power-Horse – Arpeggiator, Sequencer & More 

Groove Rider is sold as the ultimate Groove Box and that’s it. It features an full-featured arpeggiator module with 6 different modes and over 30 rhythm patterns. For endless playability, an excellent scale play mode is included with 36 different scales to select from. Also it’s possible to play chords and notes directly with the interfaces. To work directly with the app, it comes also with more than 30 different midi groove templates.

Enough space is also provided. The app allows musicians to save up to 256 user patterns in a dedicated user pattern bank. It’s also possible to import & export user patterns via the iTunes File Sharing system and format.
