23 FIRST STEPS
Take SUSTAIN SLOPE down to -32. Negative values cause the
sustain phase to fall (eventually reaching silence – you can
check this by playing a relatively long note on your keyboard).
So what do positive SUSTAIN SLOPE values do to an enve-
lope? The sustain phase rises, eventually reaching maximum if
you don’t release the note beforehand. Set SUSTAIN SLOPE to
+32 and play a long note.
All these envelope “times” (Attack, Decay and Release), as well
as what appears to be a gradient (Sustain Slope), are actually
rates. This technicality can be safely ignored in practice.
TEMPO
Via SHIFT + RELEASE (in the AMP ENVELOPE section). The
Virus has a master clock to which the arpeggiator is always syn-
chronized. LFOs and delay effects can also be synchronized to
this clock.
Locate the program ROM-A 26 “Dr.What?HS”, switch on arpeg-
gio HOLD (via SHIFT + ARP ON), and play a note on your key-
board. You can see the LFO1 indicator blinking in time with the
arpeggio because, in this particular program, it is synchronized
to the clock. Now experiment with TEMPO (SHIFT + RELEASE
in the AMPLIFIER ENVELOPE section). Did you notice how
smoothly the delay effect catches up with any tempo changes
you make?
TEMPO has a range of 63 to 190 bpm. However, the master
clock automatically slaves to any incoming MIDI clock data
(including rates which are beyond these limits). In this case, the
TEMPO parameter is simply ignored.
