I still stand by this statement very much –– a bit of chorus by modulating a short stereo delay plus some stereo reverb makes the DCO sound as lush and wide as I could ever want –– but I was thinking about the following concept.Robrecht wrote: ↑Tue Aug 27, 2019 4:38 amEven though multiple outputs would be ideal, the single output works well for me through any filter (Ripples, Wasp, Moog).
In my experience, the retrigger option is key. If you're holding a chord with your right hand and playing a bass line on the left, you don't want to retrigger the filter envelope (and re-articulate that higher sustained chord) with every bass note.
Conversely, a lead melody over a sustained chord works best if the filter envelope is retriggered with every lead note, and the fact that the chord goes through the same filter opening and closing again doesn't matter that much, as it's in a lower register.
By setting the retrigger behavior appropriately, I don't really miss having a separate filter envelope per voice, thanks in part to the individual VCA envelopes. Also, sending that mono output through a good stereo reverb makes it super lush and wide.
Since the sixteen oscillators are derived from a single analog core, they are produced as a single signal and can't be separated, right? But what if you were to add a second, identical oscillator core?
I know you can control the amplitude of each of the sixteen oscillators independently, since they all have their own ADSR envelope. So in theory, you could coordinate two oscillator cores so that they both play exactly the same notes, but core A grades the amplitude of its 16 oscillators from 100 to 0%, and core B does the same but from 0 to 100%. If the mono outputs of both cores are hard panned left and right, that should give the impression of 16 oscillators spread evenly across the stereo spectrum, no?
Like, oscillator 1 has an amplitude of 100% in the left channel and 0% in the right channel; oscillator 2 is at 93.4% left and 6.6% right; oscillator 3 at 13.3% and 86.6%, and so on until oscillator 16, which is at 0% left and 100% right.
OK, that's the theory. Now I'm imagining a small expander module -- let's say 4HP -- with the following components:
- One oscillator core just like the one in the main module
- A knob and corresponding CV input for stereo spread (from mono/centered to super wide)
- Optionally, a bipolar knob and CV input for stereo movement, making all the oscillators continually shift to the left or to the right at a speed determined by the knob/CV
- A single audio output, positioned so it would line up next to the main module's output (when the stereo expander is installed to the left of it), to form a stereo pair to be panned left and right
- Two ribbon cable connectors on the back, so you can connect both the main module and the existing expander simultaneously
Of course, this would require a big firmware update and there are probably lots of technical hurdles I haven't thought about. But it would be fun, wouldn't it?
