Novation Bass Station Rack Analog synth and MIDI/CV converter with original PSU and photocopied Manual.
Has some magnets stuck on the underside.

The Bass Station has dual-DCO's which are true analog oscillators, digitally synchronized, to generate analog but stable sawtooth and pulse waveforms (the same waveforms offered by the TB-303). They can each be tuned, mixed and synced together. The analog filter is a switchable 12 or 24dB/oct with cutoff, resonance, envelope amount, and assignable ADSR. The LFO has variable speed and delay with random, triangle or sawtooth shapes. The LFO can modulate the filter and/or PWM.A very useful feature includes the built in MIDI/CV converter which allows you to control the Bass Station from an older analog synth, or you can control analog synths with MIDI through the Bass Station! All knob settings are MIDI transmit/receivable and there are 60 user patches for program storage. Another important feature is the analog input for filtering external sound sources.
