Enticing interface but lacking basic features – RD4 - Groovebox Review

I got this app cuz it's the only 303 emulator I've seen that has standard piano keys instead of notes for the step sequencer, nice implementation and design. Sadly there's only three instruments: one synth plus a 303 and a drum machine. You can assign any one you want to the four tracks in any order, ie 3 drum machines plus one synth or 4 tracks of 303 if you want. The sound quality is ok at best, the main synth very boring sounding and not very tunable even with 3 oscillators. The 303 and drum machines are just as lacking in tuneablity. As for the drum kits they give you "punch" knob instead of a volume knob per instrument that doesn't really change anything. The worst part is the piano roll or grid mode is only for the analog synth why not every instrument? I went of the pictures in the store. Cons: No audio copy/paste - useless No advanced midi features Laggy note input with keys on real time recording Too expensive Pros: Layout and Design Multiple 303s, easy to program All in all: at the moment this is not a very inspiring music app with a few tweaks could be great. If you want something better and cheaper, I recommend Xenon, 5 tracks and grid sequencer for every instrument and they are all extremely tune-able just like real hardware. Good luck mikrosonic
