WORKING CONDITION: Excellent. This synth is back from a fresh service and sounds fantastic. The MIDI io is solid, all controls work well, and the selector potentiometer is super smooth and fast, enabling great filter sweeps. The filters are sharp and the resonance sounds great. Among its other talents, this is one crushing bass synth!

PHYSICAL CONDITION: Excellent. A few very minor abrasions can be seen, mainly on the top of the synth. The screws around the I/O jacks are slightly oxidized as well. Otherwise, everything is solidly built, well-kept, and in excellent physical condition.

FUNCTION: Analog Synthesizer 

PRODUCT DESCRIPTION: This listing is for a Studio Electronics ATC-1 Tone Chameleon Analog Synthesizer w/ MINI (moog) Cartridge

SPECS:

• Serial #C1481

• The Analog Tone Chameleon ATC-1 uses external cartridges for convincing recreation of classic synthesizers and sounds. In fact, the ATC-1 is analog, through and through! It's highly and easily editable, but a bit ugly. It has two LFO's and three envelopes. The filters, however, are on external inter-changeable cartridges. The ATC-1 usually ships with the Minimoog filter cartridge. It sounds pretty convincing too. There are also filters of the Roland TB-303, ARP 2600 and Oberheim SEM each of which cost about $150. With all that analog circuitry they all sound incredible.
  
  There are three envelopes to control VCF, resonance, VCA, OSC2 freq, OSC2 level, pulse width, LFO depth, rate and amount. There are also two great LFOs to modulate the pitch, VCF freq, resonance, OSC1, OSC2, pulse width, noise, and main volume.

  Programming the ATC-1 is also vintage in its design and layout. There is one data knob to which you must assign a parameter for editing. An annoying method that reminds many of the old Moog Source or Alpha Juno synths. This limitation in the 'hands-on' approach to sound editing is OK for studio work, but makes live performance use difficult.
  
  The ATC-1 is well equipped with MIDI and CV / Gate ports. There is also an external audio input to the VCF (filter). In all the ATC-1 is a state of the art synthesizer with a simple goal, emulating the classics while offering current specs for MIDI, memory and extensive edit-ability in an expandable, compact and intuitive machine.
