I have Reaper & love recording with it. I really hadn't ever recorded on my PC, I have a BOSS BR-8, BR-600 and BR-1600 recorders, and my PC wasn't really set up for recording.
But I wanted to learn more about PC recording. My brother sent me a
Edirol UA4FX external audio device that came bundled with SONAR LE. My PC was hanging with SONAR, and I read that Reaper used less CPU resources.
I downloaded the fully working demo, and after a few days of learning the recording steps, brought a home use license ($60). There is a learning curve, but the most all the features are very intuitive IMO.
Reaper has RealDrums, which I could never figure out, and the fact of not having drums, or having to drum software kept me from using Reaper on a regular basis. Than I brought a copy of
Drumcore ver 2 on closeout from Sam Ash for $79.99. Wow, this made a huge different.
With
Drumcore, you simply drag & drop a drum groove right into Reaper.
Than I learnt about DX & VST(i) plugins! I must have over 200 different plugins. Once you download a plugin, and un-zip it, you simply copy the .dll into Reaper's plugin folder. The next time you start Reaper, the plugin will show in the plugin list.
Just a couple of weeks ago I got a
M-Audio Axiom 25 MIDI/Controller. The A-25 has transport controls, which mapped to Reaper's transport. The A-25 also works great with all the soft-synth patches I have now.
But the most important feature of Reaper are the free updates, and user support
