is there a sinewaves or sinusoïdale waveform vco ae modular ?
or indeed use the wavefolder module by put the vco or 2osc/d in to create it ?

Hi garden, at the moment there isn't a sinewave oscillator, but I think Robert is working on one. You can get a sinewave either from sending the triangle wave from the VCO through an LPF, eg. via SVFilter, or you can get one of the filters to self oscillate. For instance the SVFilter is beautiful when self oscillating, but of course the pitch is hard to control. |

Yes, some new oscillators are coming up very soon, and they will be able to produce sine also.
The wavefolder is not the right tool for this; a wavefolder always brings in new "edges and corners" into the waveform and therefore increase the amound of harmonics; while a sinewave is only the basic harmonic.

Another way to get the sinewave from a triangle would be to use a slew limiter such as the SLEW/EDGE. If you leave it running, then feed a triangle in from a VCO, you can adjust the SLEW/EDGE to "mush" the sharp curve transitions, which will give you a pretty good approximation of a pure sine. This is sort of the exact opposite of what the WAVEFOLDER does...that module actually folds and skews the waveform, which tends to create additional sharp curve transitions (and with that, more harmonic content).
It's actually an old ARP 2600 trick...too bad Korg thinks that only SPECIAL people are worthy of owning one now...  |

It also looks available (eventually), which is something you can't say about the KARP. I spoke with one of the sales reps I deal with routinely earlier this afternoon, and his company is also scratching their collective heads at Korg's weird behavior as of late. They're sort of at a loss for what's more insane, the release of only 500 units of a synth that everyone had been waiting for since ARP's shutdown in 1981 (given that retailers back in the day were PRAYING that Rhodes would also continue the 2600 and not merely the Chroma), or reREreleasing the MS-20 in a slightly-larger version that's more than twice as expensive as the version with which they've spent the past several years saturating the market.
Someone in Korg's marketing clearly seems to have gotten hold of some of that vintage Woodstock "brown acid". And I ain't buying any of their stuff until/unless that person(s) is trank-darted and put in a rubber room for the safety of the company.

We are forgetting the easiest way to create a sine on a modular : self-oscillating filter ! Only downside is that it doesn't track 1V/O. Another way to get the sinewave from a triangle would be to use a slew limiter such as the SLEW/EDGE. If you leave it running, then feed a triangle in from a VCO, you can adjust the SLEW/EDGE to "mush" the sharp curve transitions, which will give you a pretty good approximation of a pure sine.
In doing this, you are effectively using the slew/edge as a low-pass filter, which is yet another great use of a slew limiter ! And please Robert... No more teasing  |

Turn the resonance all the way up.
