The sounds packed into a sequencer that works in such a way that you choose one of 18 pads that will bring forth a line with a small marker moving from one side to the other of the line you decide how long to make the line, the placement and the volume of each line.
It will make a sound when it when and where it intersects with another line.
Each line have one sound out of 23 that you choose so you could choose three sounds but have 18 lines going.
Sound simple but it can become complex rhythmically if you want it to. What is good with the applications is that it a nice collection of tasteful small electronic noises that in themselves without the sequencer could be useful for music making.
Maybe the best use of it is to set up a sequence that you like (maybe while the music that you are working on is going in the background) and record it and chop it up.
It does not come with a built in record function but you can save the scenes that you are working on.
For free and with small but not too obtrusive publicity if you are connected to the internet.
It is one of these applications that you will find use for soundwise sooner or later as it is not any other ones that I have heard with a similar soundset or at least not this nice.
And of course the sequencer is a nice bonus and will help you come up with rhythmic ideas that would be hard to come up with if you programmed it in a traditional sequencer...
