Orion Pro

From Sonic Syndicate:

Orion Pro is the affordable edition of Orion, for beginners and experienced users alike. It provides all the essential tools to get you started making music with your computer: sequencer and playlist for arranging the parts of your song, a selection of generators with preset sounds, a range of effects to process and modify those sounds, and a mixer with everything you need to to bring it all together.

With an ASIO compatible soundcard, Orion Pro can achieve latency as low as 2 milliseconds. VSTi and DXi standard instrument plug-ins are supported, giving you access to a wide market of instrument plugins. The Sampler comes with an integrated Groove Slicer, which automatically chops up beats and grooves, which you can then rearrange in the sequencer.

If you're ready to begin composing original music yourself, Orion Pro is for you. It provides you with the tools you need to create your own unique sound, and compose your music from the ground up - at a fraction of the price of even a humble home studio.
