The first LabSeven module, representing the VCO of a well-known 80s synthesizer (with a few extensions), is now available via the plugin manager. It comes with the standard blue and a classic gray skin. Enjoy!
P.S.: If you like it and want me to keep on creating VCV Rack modules (apart from completing the 3340 series I already have plans for some unusual but I think very useful stuff), please consider a donation. Any amount is welcome 
I may be showing terrible ignorance here, but I’m dying to know where the “3340” comes from.
It is a tribute to a VCO chip widely used in hardware synths 
I remember now.
Anyway, lovely oscillator. I’ve been playing with it all evening, looking for the perfect filter to pair it with.
Lindenberg Laika is always my first choice.
Nice!
A filter that goes very well this VCO is based on the IR3109 which I think uses LM13700s. That would be another module needed in order to complete the 3340 series.
I decided to better not call it VCO-101 any more for obvious reasons. But yes, that’s the one!
It sounds like a gnarly beast if you pair it with Lindenberg’s Valerie filter (basically the Korg 35 filter made into a module)
I’ve been having a blast while playing with this for the last few hours. Using the noise as a modulator to the pitch generates some really cool and unpredictable glitchy sounds.
This is certainly the truth. In fact, anyone not familiar with the Lindenberg modules is doing themselves a disservice. Except…Westcoast often causes me trouble. I like the sound it makes but it often causes VCV to cut out it’s sound entirely until I reload. This makes it an unacceptable risk during streams so I don’t use it. Also, they look cool.
Just used the VCO-3340 for the first time in the studio, listening with (relatively) big Adam speakers. The ‘classic’ sound is definitely there but, using the modulation and RANGE/SEL inputs, it does not take long until you end up with some really f***** up s*** 
Pro tip: Use the VCO-3340 at sample rates of 96kHz or higher in order to release its full potential (modulation frequency range etc.)
Just fixed a minor bug. Update with bug fix + tidier code + minor performance improvements coming soon!
Possible silly question - how do i access the grey skin?
EDIT - answered by own question. Obviously haven’t felt the need to be in users/xx/rack/plugins for a while…
Simply copy the LabSeven_3340_VCO.svg from the LabSeven_3340_Classic_Skins folder to the res folder above.
Version 0.6.2, correcting a small tuning error, is on github.
Hi! Any chance for a 1.0 version? thanks
I’m not 100% sure but the vco in Valley Interzone looks fairly similar to vco-3340.
even better
Hi! I am very busy at the moment - I’ll port VCO3340 as soon as I have time.
