Well I’ve always liked groove boxes and apps where you can do everything in one place. From the developer who brought us Poison-202, comes Groove Rider GR-16. This 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).

Check out the patterns demo video:

One remarkable feature of GR-16 is that it has made all of the controls available on just one single screen, like on a real groove box device. Groove Rider GR-16 lets you access almost all useful parameters from this one single screen, and so you can forget about loads of sub-windows and dialogs, which can ruin your inspiration and workflow. Groove Rider is the fastest path from your imagination to reality!

You can use GR-16 as a ready-to-go realtime musical instrument (groove box) in your jam sessions together with Ableton Link feature to synchronize it with your other music gear. Groove Rider is also very handy for quickly sketching your musical ideas, allowing you to instantly record them directly by using the Record function. Making music becomes easy and fun, in contrast with boring note drawing process and dealing with tons of files and expensive plugins in the DAW’s! Don’t loose your inspiration, boost it up with Groove Rider!
