IV YOU'RE IN A HURRY. . . CONNECTING THK DS-2 TO YOUR SYNTHESIZER 1. The DS-2 si ores cuntrol voltaic signals from your synthesizer: Connect a patch cord from your control voltage output to the jack labeled "CV IN" on the back of I he DS-2. 2. The DS-2 sends stored control voltages back to your synthesizer: Connect a patch cord from the jack labeled "CV OUT" on the back of the DS-2 to the rontrol voltage input of at least one VCO in your synthesizer. 't. The DS-2 also stores the* length of time between trigger signals from your keyboard: Connect a patch cord from the trigger connection of your synthesizer to the jack labeled "TRIG OUT (TRIG IN)1' on the back of the DS-2. (For ARP 2600's, also connects a patch cord from the "+15" jack on the DS-2 to the "GATE" jack on the 2600.) 4. Kor most synthesizers, the connection made in (3), above, serves for both trigger signals to the DS-2 and trigger signals from the DS-2. For certain synthesizers, however, an additional patch cord must bo connected between 'TRIG IN" on the DS-2 to the trigger output on your synthesizer. 5. Set up a standard keyboard patch on your synthesizer, using as your sound source only the VCO(s) that are under the control of the DS-2. Be sure, of course, that the synthesizer is turned on. ('.KITING READY WITH THE DS-2 1. Turn on the power to the DS-2 with the power switch in the lower left corner of the upper panel. 2. Press the first LOAD button on the right-hand side of the lower panel. 3. Set the CLOCK RATE knob so the arrow is pointing to the " 12 o'clock" position. 4. Re sure that the three toggle switches in the middle of the lower panel an* off (down). AND NOW USE IT. IT'S AS SIMPLE AS ... . . . ABC Play any series of notes-high, low, long, short, but not more than 24. As soon as youVe hit the last one, punch the TERMINATE button. You will hear the sequence repeated exactly <>y your synthesizer, under the control of the DS-2.

MAKING THE ADJUSTMENTS The DS-2 stores control voltages from your synthesizer which occur in discrete increments, namely 1/12 volt per semitone. While most popular synthesizers (such as Arp and Moog) nnnuiuillv put out such a voltage, in reality, the actual voltage put out by your synthe sizer may he slightly different. If your DS-2 is not precisely adjusted for your synthe sizer, notes may sound flat or sharp during play, and/or certain notes may he skipped or repeated when a chromatic scale is loaded into the DS-2. However, don't make these adjustments needlessly if the pitch of the AV-J during playback scenic okay. The diagram below shows the locations of the three DS-2 adjustments: OPFSLT Ml adjustment pp^edures assume that the DS-2 is connected to your synthesizer and *c(|ii!'nces can be loaded and played back.
