Thank you for purchasing the S T UDIO E LECTRONICS ATC- X. You're soon to discover the world's only 4-way discrete multi-filtered analog synthesizer. Like never before, you now have the ability to create and explore all of the classic Analog synthesizer sounds in one powerfully expressive and versatile machine.

Setting Up the Instrument A. Plug the power supply cable into any conventional A.C. outlet. With its auto- ATC-X switching power supply the is capable of accommodating voltages ranging ATC-X from 90 - 250. So, wherever you and your are in this great big world, proper operation is a cinch.

*Note that the display blinks momentarily after each press, informing you that your action has been recognized. The Rotary Encoder ATC-X The main user interface in programming the is the rotary encoder; which turns smoothly in either direction for complete control. After a switch pad is pressed you will use the encoder in almost all operations to edit or change any desired function or parameter.

The waveshape selectors determine the harmonic spectrum of the signal, its basic timbre, or tone color. ATC-X 1 has two oscillators that each produce three waveforms. All the waveforms are continuously being generated, so they are available to be outputted either individually or simultaneously, depending upon how they are selected.

Selects the mix level of Oscillator 2 (same potential for harmonic distortion as Oscillator 1). Selects the mix level of the noise or distortion. Noise is a random signal, a ATC-X rushing, static-like sound. The 's noise generator produces white noise.

The ATC-X with its unique interchangeable filter system features four classic wide range lowpass filters, and in the case of the MINI and 2600, "resonant" filters (see VOICE ARCHITECHURE). The Filter attenuates, or "cuts- off" the higher frequency components––those which lie above the adjustable cutoff frequency, and passes the lower frequency components of the audio signal.
Page 13
The filter envelope shapes the timbre and overtone content of the audio signal as it passes through the modifying circuitry from the mixer. This envelope or "contour" generator is used to dynamically move the cutoff frequency. It works as such: each time a key is depressed an envelope or "contour”...

E n v e l o p e 2 : V C A The volume of the audio signal, which passes through the VCA envelope, is contoured by the envelope controls. Each time a key is pressed, the envelope or "contour" generator attached to the amplifier is actuated, and sends a control signal to the amplifier.

E n v e l o p e 3 : A ss i g n a b l e Envelope 3 can be assigned to modulate a variety of different parameters to create unusual textures and interesting effects. See the target list below for the parameters Envelope 3 can control.

LFO 2 LFO 2 can be synchronized to MIDI time clock (see PROGRAM). The ATC-X also has the capability of allowing Oscillator 2 to modulate Oscillator 1 and the frequency of the filter. This is known as Audio Frequency Modulation because the modulation control signal, in this case Oscillator 2, resides in the audio spectrum.

ATC-X is completely controllable by MIDI, with a long list of parameters and functions assignable to Velocity, Modwheel, and Aftertouch. Certain sound parameters also have a dedicated Continuous Controller assignment (see chart on page 16). In addition, parameter edits made by the rotary encoder are transmitted as Controller data.

Selects the MIDI clock assignment to LFO 2. The rate of LFO 2 can be synchronized to incoming MIDI time clock sent from your sequencer. The beat divisions available are: 1 1 = whole note, 2 2 = half note, 4 4 = quarter note, 4 4 - - 3 3 = quarter note triplet, 8 8 = eighth note, 8 8 - - 3 3 = eighth note triplet, 1 6 1 6 = sixteenth note, 1 6 1 6 - - 3 3 = sixteenth...

Located in this section is the display and rotary encoder, which along with the membrane front panel, makeup the user interface. Playing ATC-X and programming the involves two basic modes of operation: Patch Play Mode and Edit Mode. In Patch Play mode, the unit will ATCX cycle through its 512 patches when the encoder is turned.

Although the ATC-X has been thoroughly tested for potential software bugs, we cannot simulate all possible user setups. So in some instances, the ATC-X may "lock up" or "stick" on a note. To rectify this situation, try one or more of the following fixes: Play and hold more...
