3U rack-mount format, the Supernova II was also available in a 61-note performance keyboard version with velocity and aftertouch, enabling sound tweaking during live performance. FM synthesis capability was included along with ring modulation, dual analogue inputs and a 42-band vocoder. An 8-part arpeggiator was also on board and in its full version the product offered 8-part multitimbrality and 48-voice polyphony, with 57 and 2304 oscillators running simultaneously. A-Station (2001) was a cross between the BassStation and the Supernova. With voice architecture was based on the Supernova, A-Station added 8-voice polyphony and a basic FM synthesis engine, reverb and delay, plus a 12-voice vocoder for processing external sounds – which can also be used as an oscillator source and processed via filter and envelopes. An arpeggiator was also provided. K-Station (2002) was a 2-octave keyboard version of the A-Station with 8-voice polyphony, three ASM oscillators providing a range of waveforms plus FM synthesis and a noise source, a 12-band vocoder, arpeggiator, dual ADSR envelope shapers and two LFOs, reverb and delay effects. KS Series (2002) – KS4, KS5 and KS Rack – used enhanced versions of the K-Station engine with a range of additional features. The KS4 was a 4-octave keyboard, while the KS5 offered five octaves. Keyboards are semi-weighted and include aftertouch, and all 33 control knobs on the ergonomic control section send MIDI. The KS Series included four-part multitimbral operation with multiple assignable audio outputs, a 14 band vocoder and a separate effects processor for each part. ReMOTE 25 MIDI controller keyboard (2003) was conceived in 2003 to bring back "hands on" tweaking to the computer musician. In addition to the ReMOTE 25, which was MIDI based, the ReMOTE 25 Audio provided the same facilities with the addition of a built-in USB audio interface and later developed into the X-Station. The ReMOTE keyboards were originally developed as controllers for Propellerhead Reason''. V-Station and B-Station (2003). These software products, still available as of January 2017, provide virtual emulations of the K-Station and Bass Station respectively. Both are available for Macintosh and Windows platforms, in both VST and AU formats. X-Station (2004) was designed to create a complete music-making environment by adding a computer/sequencer, microphone and monitoring. Supernova class 8-voice ASM-based synth engine, template-based ReMOTE style MIDI control and a 2-in, 2-out stereo audio interface and multi effects engine plus semi-weighted aftertouch keyboard. ReMOTE Zero SL (2006) was an addition
