The grey area in the upper area of the DIVA interface is comprised of four sections, each of which has a selection of modules to choose from. On the left is the oscillator section, for which you have four choices (Figs. 2a through 2d). These are:
the second oscillator a slave of the first (the detune button thus controlling the timbre rather that the pitch of the slave). Both oscillators can be set to octaves between two below to two above the central pitch.
The purpose/function of nearly everything is obvious. Of those few things that aren’t, many can be understood with a little ♪ Dual VCO (multi-wave experimentation and the oscillators with sync, PWM and manual fills in the rest. This cross mod) makes it is a good time to take ♪ DCO (single two wave a small detour and talk about oscillator with PWM and flexible the Scope tab in the lower sub-oscillator) section.
♪
Triple VCO (morphing oscillators with FM, sync and filter feedback)
♪ Dual VCO Eco (CPUfriendly with pulse width and, ring modulation) Each of these is reportedly constructed from (modeled on) a real-life piece of gear. Some clues as to what that gear was can be found in the preset browser which, along with the actual musical patches, offers a small set of templates with names like June-60, Jupe-6 and Minipoly.
In the center of the lower panel is a tabbed area, the fourth tab of which is labeled Scope. This is a simple oscilloscope display. When in doubt about what the oscillator settings do, this can clarify a lot of what the ear can’t definitively tell you.
Sliders and knobs with a small downward-pointing triangle next to the label can have alternate modulation sources selected. In a gesture of whimsical panache, when this Let’s look at the Dual VCO choice a little more closely, just is done, the “painted on” label is overlaid by the image of a to explore one model.
