Recorded on a beautiful sunny sunday morning...if you hear some lags in the tracks, sorry for that, but my laptop had little problems while recording, because of the heat! These lags are not from the software I used on my Nexus7...Anyway I hope you enjoy;)

So here it is  a new drum machine capable and grooveboxy from the creator of G-Stomper Studio and VA-Beast. It is for free and without the dreaded publicity!
It is really a "scaled down" G-Stomper Studio but marvellous in its own right.
So the differences is that it does not come with the VA-Beast synthesizer and without song mode. But with a 24 track sequencer that you can expand to 8 beats which is more than enough especially for live manipulation. Actually it is G-Stomper Studio with the exception of the parts above and it does not have sample import meaning that it comes with the same drums/drum sets as G-Stomper Studio with the possibility to buy extra sets.
And lastly being made for drums the piano roll step sequencer has fixed pitch but this you can easily set in the main view for each drum.
What is great with this is that if you think that G-Stomper has grown too big and you miss when it was just concerned with beats here you have it plus better than the earlier 
G-Stomper Beat Studio in many ways as in audio quality more effects etc.
The other great news is that if you wanted to get into G-Stomper Studio but found it too confusing and with too much options here is the chance to get a application that is really good for free and learn all the basics before you update where you get more functions plus the excellent synthesizer VA-Beast.
In either case this should have been sold for some euros as it is very complete as a drum machine / Groovebox but being for free (or not) it is something that I highly recommend to go install in this moment already.
