What surprised me was that not until sitting down now to write about it,
is that it in Android apps years an oldie goldie, all the way from 2011!
It does look more up to date though.
Some of these apps that have not been updated can be problematic to run but it works fine on my main device but it runs on Adobe Air and Adobe flash so it is possible that you need to install those before getting it to run.
There is no Synthesizer engine but you have a broad selection of sounds to choose from plus echo and LFO filter to play with. Allows for many tracks and sequenced parts and can be used for whole tracks.
Strangely enough being for free and without publicity it has had less than a thousand downloads. Maybe it was too demanding for the devices when it came out and then got forgotten and hidden in search results?
In the end it is a nice multi track sequencer application with decent possibilities.
