the reason i make music
good choice with reason. id share with you if i had a fast connection (but please support good app developers and buy it if you can afford it; it lets everyone make music for less $).
i use it everyday. i have a solo project (neusound, with one local cd release) and a group project (organech, with one local demo and one full length album) that i use reason with.
it can be played live or used in a studio setting. when you start to expand, it expands easily into cubase or nuendo for midi control and recording. external midi devices (ie. keyboards, controlers, drum pads, switches, etc) can easily control reason and give you more hands on tweaking and playability.
it has the abilty to create music with loops players (rex), samplers (wav, aiff), drum machines (wav, aiff), and synths (low-to-high range synth quality). and all these can be routed through fx units (chorus/flange, phaser, delay, reverb, 2-band eq, distortion, and compressors). you can create as many of these units as your computer can handle.everything is real-time and emulates the real hardware (you can even re-route the cables coming out the back of each unit).
reason was put together for "techno" style music, but this software was used hevily by NIN's Charlie Clouser to make excellent music for NIN and others(can also be heard in the Gorilla's album and remixes). It can be used in conjunction with re-birth to take advatage of the well emulated 303, 808, and 909 (used by Clint Mansell to make most of the loops for the movie Requiem for a Dream).
if your familiar with re-birth, like you stateted, you'll quickly fall in love with reason. look out for my upcoming web sites (homepage.mac.com/organech and homepage.mac.com/neusound) for music made with reason, re-birth and a live band.
