New G2 Killer(not really)

Actually the VS/Wavestation vector synthesis was just a marketing term for cross fading (interpolation) between waveforms that may or may not be being wave sequenced. This is only slightly more interesting than wave sequencing alone. Nice filters in the VS though.

I saw somewhere a list of descriptions for the wave tables in the original PPG wave. They were tables, pre calculated (on a PDP11?). Simple things like different combinations of sines, pwm or filter-ish sweeps. All stuff that could most likely be patched in real time on the G2, without the nasty stepping (or you could maybe even simulate that with some sample and holds).
Later models had bigger, higher resolution, downloadable tables but that is strolling into sampler territory

omgwad

you know what else is great about wavesequencing on the g2?

so you have your eight waveforms going into yr x-muxer. what's to stop you from having another few x-muxers with different envelopes?

it saves on the processing, and you can make huge evolveing pads that way-the waveforms are running all the time after all, so it's not that much more of a drain to have them running through different chains.

will post patch after i make it sound good:) but indeed, it does sound a bit like the wavetable synthesis i've heard before.

I think we should create a sub-forum for these kind of discussions. It's annoying to see these posts. It would be nice if these kind of opinion/flame war starting discussions be moved over there. I consider them neither useful or a benefit to this forum. This way the moderators can move it over there for people who want these kind of discussions and take part in them.

here's what i'm not sure about, though.

g2ian, are you sure that "interpolation" in that context meant just "crossfading"?

oh!

right

i thought you meant something else by "not simutaneous"

I never played a Prophet VS, but -

The basic "vector synthesis" engine was designed by Chris Meyer, a guy I used to know and occassionally play with in college. We got together a few years after after that synth came out, and he told me how he pitched the idea to Dave Smith: he basically patched it up on an old EML modular. As I remember, while there were some sampled waveforms in the synth, they were not wavetables by either of the usual definitions (sweepable tables as in the PPG, or static samples as in ROMplers). So to call this a wavetable synth would be inaccurate.

The key to the sound, as I recall him saying, was that they took care to make sure all of the harmonics in the various sampled waves were in-phase, so that there would not be strange dips in level as the crossfaeds occurred. But that's, in essence, all there was/is to vector synthesis: crossfading.

the main thing that really excited me about the prophet was the ability to save waveforms at the push of a button.

yeah, by simultaneous I meant being able to send evolver oscs to g2 and send g2 back to the filter of evolver.

Erm, I thought the G2 *does* have wavetables? As far as I know the oscilators are based on indexed tables.

Yep, VMS is a nice freeware program, created in addition to the Nord Modular Rack, I believe...

BTW the statement the Nord Modular has an open end... How far does Clavia have to go? It has a lot of possibilities, for sure.

that bit about wave sequencing needing the oscillators to be in pahse with each other is no joke. i mocked up a wavesequencing synth in the g2 last night (it's over at the experimental patch section). when they are not synced together, they phase alllll over the place, and it makes the sound very odd.

i am not a big fan of waldorf products, but i am glad that there back (they deserve it Smile

I love my Waldorf Pulse, a 3 oscillator monosynth with 4 slots of modular routing, it has a terrible physical interface.. but it sounds fantastic to my ears and is pretty cheap these days.

It's a perfect compliment to the G2 as every parameter can be controlled via cc. Instant modular analogue monosynth! I'm pretty sure the Microwave has a similar midi spec.
