Great rompler.

Yes, this was my first groovebox, a kind of module with workstation functions in a box.

I use this machine to make rhythms, also to play 7 sounds at the same time for a multilayer result to play the same notes, I save these sounds as songs because it doesn't have the option to save multi-presets.

It has a drum section with 8 sounds and then it has 7 more tracks for bass keyboards and effects or percussion, 348 sounds in rom.

The machine has good FX quality, the filter is a bit thin, but it does its job well, it's not bad, but it could be improved.

Probably the rompler with roland's most famous sounds.

Preferred Settings + Usage:

drumkits section and FX

It was great, it is great

And I'm a proud owner of this first groovebox, since 1997. Acid samples, techno presets (perhaps too much) now outdated. But programming was a breeze, I had hundreds of hours of fun with this big little machine. Cut-off on every single track was a pleasure.

90s in a box

This thing is mad fun to program. all the sounds in it will take you back to the 90s. only real draw back is that its loaded with uneditable preset songs and only gives you 50 patterns to fill so 1 live performance routine is pretty much the extent of what can be held but that can be stretched thanks to the 8 parts per pattern

Iz OK

Somewhat limited sound bank, but for an analog step sequencer and and old schooly interface, not bad. Manual time sync sucks.

A fun piece of gear

I haven't gotten as much out of this unit as I'd like so far, but it's a fairly capable digital sampled synth with some analogue-modelling features. Combination drum machine and synthesizer, which is nice if you're short on mixer channels.

Killer Bass

The best digital bass you can get for the price and the filters still sound fat

really fun instrument

Making music is easy on this thing. cheap. sounds good. borderline hilarious. It's the year 2015... ditch your laptop and roll over to a party with one of these and you will get some serious attention.
