"Seventies bass synthesizer in good working condition. the low C key sticks and the middle C & D work intermittently but otherwise all functions and keys operate as they should. Comes with lid.

From the web:

In 1977 German organ company released the two in one Bass Synthesizer AP-6. Its a bass syntheszer and a bass guitar synthesizer in one with a quarky glide setting named "Hawaii" which worked as a slide guitar function presumably to play Hawaiian style slide guitar riffs.

The robustly built instrument is monophonic with square, saw and sine waveforms. There are 5 organ stops for playing various octaves. 3 envelope generators are available with attack and decay for the sine waves and attack and decay for the filter envelope. The bass guitar section only has decay available as an envelope.

The filter section is a formant filter which acts like an autowah than a traditional analog filter. There are 2 LFO modulators available LFO 1 is a rotorary style effect and LFO 2 is vibrato effect with a normal and slow setting.

There are 2 slider performance controls, 22 buttons and 10 knobs available for creating and setting sounds. The unit features 37 keys and is built into it's own case with lid for transporting. The output section has two monophonic outputs for low and high impedance."
