Vintage ARP Axxe synthesizer keyboard

via this auction

"The one oscillator's saw and pulse outputs can be mixed with the white noise source. The oscillator may be modulated by LFO (square and/or sine), random sample & hold, and ADSR. Pulse width adjustable from 5% to 50% and may be modulated by LFO and ADSR. 4 pole voltage controlled filter with self-oscillating capabilities. Filter may be modulated by keyboard control voltage, random sample & hold, LFO and ADSR. Normal keyboard triggering mode, as well as keyboard repeat and auto repeat. Pitch bend control, portamento/glide, and transposable up and down 2 octaves. 37 note keyboard.

The case has some holes that have been plugged from a previous MIDI mod which has been removed. The trigger in/out jacks are taped off inside the case (the holes they normally mount in were enlarged by the previous owner). Sliders were replaced and oscillator tuned to get everything working, but otherwise the synth wasn't serviced or restored in order to keep the price affordable. The keys all work, but the bushings are old and the contacts are dirty, so sometimes a key may double trigger. Some wear and marks on the panel, as shown."
