[. . . ] Let's take a look at the internal modulation sources: AMPENV & FILTENV The corresponding envelope is the modulation source. According to the fact, that the note off velocity is only known when the key is released again, here, the VIRUS uses the note on velocity, when the key is held. KEYFLW The note number respectively the pitch is used as the modulation source (Keyfollow) RANDOM A random number which remains for the whole duration of the note on, is used as the modulation source here. The control range of the source may be limited via the AMOUNT values or inverted so that the modulation occurs strictly within the desired value range for the target parameter. For your target parameters, you can chose from among virtually all sound parameters that feature an infinitely variable control range ­ ergo, you have more than 100 modulation destinations at your disposal. If you haven't selected a source for one of the ASSIGN options (SOURCE = OFF), the subordinate parameters will not be displayed. ACCESS VIRUS OS4 131 Assign In addition to the three ASSIGN options, the user interface features ­ as discussed earlier ­ a freely definable modulation destination for LFO 1 and 2 called ASSIGN.

The clock generator works either internally with a freely variable speed or it can in turn by synced up to the MIDI clock of an external sequencer. This synchronization occurs automatically when the device receives a MIDI clock signal via its MIDI In. You can vary the speed of the clock generator within a range of 63 to 190 BPM (beats per minute) via CLOCK TEMPO. When the device is synchronized via MIDI clock, the clock generator automatically accepts the speed dictated by the connected sequencer; the internal tempo is invalid. The individual sections of the Virus are synced up to the clock generator at rhythmic intervals such as 1/16, 1/4 and so forth. (ARPEGGIATOR CLOCK, CLOCK LFO 1, CLOCK LFO 2, CLOCK LFO 3, DELAY CLOCK, see the respective sections). 01111111111111111112 1 CLOCK Tempo (bpm) 120 61111111111111111154 In SINGLE MODE, CLOCK TEMPO pertains to the current SINGLE PROGRAM and is stored along with it. [. . . ] If this product is found to be the source of interference, which can be determinated by turning the unit , , OFF" and , , ON", please try to eliminate the problem by using one of the following measures: Relocate either this product or the device that is being affected by the interference. Utilise power outlets that are on branch (Circuit breaker or fuse) circuits or install AC line filter/s. ACCESS VIRUS OS4 287 FCC Information (U. S. A) In the case of radio or TV interference, relocate/reorient the antenna. If the antenna lead-in is 300 ohm ribbon lead, change the lead-in to co-axial type cable. If these corrective measures do not produce satisfactory results, please contact the local retailer authorised to distribute this type of product. [. . . ]
