A Question on Korg Delta connections

Postby Alex Hamilton » Sun Jul 06, 2008 12:35 am

Hey,

The Korg Delta has connections for:
VCF fcM IN
TRIG IN
TRIG OUT
synth and string seperate outs
synth and string mix outs (high and low)
phones out

Most of these are self-explanatory, but what's the point of the TRIG options? The Delta has no way of controlling the pitch using an external CV (or sending a CV to another synth), so why would you choose to trigger the envelopes externally, and vice versa? Does anyone have any recordings of applications that they've put it to? I'm intrigued as to why Korg would only give it 'half' external control. :?:

Well, the trigger out could be used to control the envelopes on a modular system or another Korg of that vintage so that you could play the Delta through another synthesizer without having to trigger the envelopes on that synthesizer.

The Trigger In plus the filter control in could allow you to control the Delta from another synth, as long as you played the chords or notes... which wouldn't necessarily be unlikely when it was released.

Thanks for the reply. This, though, wouldn't allow you to control the pitch of the oscillators on the 'slave' synth, making it very limited - you'd have to control the pitch using a CV from another source (although obviously this has its own experimental applications). Or are you talking about maybe using it to trigger the envelopes on e.g. an external filter, into which you're running the Delta output? This seems like it would have actual application, but it still seems half-arsed to have not put a CV out on the Delta.

But why would they not put in a CV in, so that you didn't have to hold down the keys? You could drive it from a sequencer triggering the envelops, while using the Delta's paraphony to allow it to sequence chords as you hold them down, but you could do this with a TRIG in anyway - you'd just have to not connect the CV in.

Thinking about it, this probably answers my own question: you would only be able to drive the Delta monophonically from an external CV (unless you had multiple inputs), which although has its uses, it's primarily a chord machine. Also, it would only be able to put out one CV if there's only one output, despite the fact that it can generate many, leading to the rhetorical question as to how it would prioritise if you put down two notes at the same time.

No, it wouldn't control the synth at all, it would just allow you to use the synth's non-oscillator functionality. It's not like MIDI; it's just a situation wherein you could add functionality to the Delta. It's most ideal application would be with a modular synth.
Seems like unnecessary expense and effort on the part of Korg, though.

Well, the deal is... it wasn't designed for sequencers... most people played their synths back in 1979. It's not about the control of other synths, it's about playing through them to use their filter and functionality in realtime.
Since the Delta was divide-down, they merely went for a means of using other synths filters and functionality.

It's not the only stringer with a trigger out - didn't the RS-202 have one? The RS-101 doesn't, though (shame).

Yeah I guess that's it - you can set the Delta's synth envelope to a simple gate, so you could then shape it externally, just leaving the filter open.

Thanks for your thoughts, appreciated.

The Lambda has one, too.

You should hear the Delta through an MS-20's filters, using the trigger out to control the EG's on the MS-20.
Also, it wouldn't control the delta monophinically if they included a CV in, the Delta was divide down circuitry, just like an organ.
