free TR 606/808/909 for Windows
Who says you only get what you pay for? This donation-ware download from d-lusion is a hidden treasure for those in search of simple drum programming and great sounds on no budget. It's been around for a while but I came across it again recently and fell in love all over again with drum programming. Also check RubberDuck, a re-imagined TB-303, and the MJ Studio MP3 mixing tool. Don't forget to throw a few beans in d-lusion's Donation bucket for providing all this great stuff for free!
From the d-lusion site:
"Based on the concept of the legendary Roland drum synthesizers TR-909, TR-808 and TR-606 whose throbbing bassdrums and crashing hihats sent generations of dance-music enthusiasts into extasy, Drumstation combines cool old drum machine features with cutting-edge software synthesis technology. Drumstation is a drum software synthesizer and features 8 channels of drums (either samples or synthesized drum sounds), programmable via an easy-to-use step sequencer, effects (realtime reverb, delay, flanger, filter, distortion) for each channel, loops could be sliced and stretched.
"All this in the year 1998!
This free downloadable version also contains - beside the standalone software synthesizer - a complete set of free drum samples and effects to get you started (Roland TR-606, TR-808, TR-909, Real Drums, Sound Effects, DR-101, DPM-48, and additional Yamaha/etc. sampled sounds)."
