Rubberduck is a bass synthesizer that was originally released for Windows 95 in 1996. Roughly based on the the well known TB-303, Rubberduck's synthesis model consists of an oscillator wave with a resonant filter sweep applied to it combined with a hardware sequencer design which resolves in the typical twisted, screaming, bubbling bass sound that is often used in Acid House, Goa Trance, or Techno productions. Rubberduck features realtime digital resonant dynamic filters, frequency and volume envelope (DCA, DCF), 4 basic waveforms, dual oscillator sound generation (starting with version 2.0), a 224 note sequencer, a drum section where samples could be synchronously played back, an effect unit (delay/feedback/distortion) and is fully Windows 95 compatible.
Drumstation is based on the concept of the legendary drum computers TR-909, TR-808 and TR-606. It 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. With the drumkit manager, you can create your own drumkits.
