Thanks for all the kind words.

As for Linux. It may be a thing for the autumn...

I made an extremely unplanned and long video if anyone is interested in the oscillator of the new synth. I have a regular product video that will be released on thursday, but I realized it didn't really show how it is to work with... So if you wanna kill time or just get more bored:

I`d see it so:
- just add a offset position to the modulators on the VCO section for the 2nd voice. Nothing else.
- could probably be even good enough to offset just one or two parameters. Vs. one: phase. Vs. two: the tilt/skew parameter on top of it. Just a feel......i might be wrong.

Just throwing here in some thoughts that have strived me. :)

edit:
I like it sequenzed from a 303 .....as you did in one of the videos. (i use the ABL3)
But when i hand-play it the wish for a (semi-) duophonic mode comes up frequently.
I won't rule it out. I will look into if I find something I find usable after the summer vacation. I have a few other things I wanna try with it anyway. No promises though.

In other news... ...I have yet another oscillator on the drawing board, but I keep telling myself not to start on a new synth for a while as it kind of takes over my entire life during the development process...

All the Best,

I love videos that totally nerd out, and this one gives me a better insight into your creative process. It seems like a completely unique way to use a synth. I can tell that this will be capable of extremely digital sounds, which will be exciting. It looks great, and I'm looking forward to trying it out. :tu:

Thanks. Yeah, the sound palette of it is one of those things that keeps surprising me as it is quite simple in many ways. I think there is an example in the video where I turn up through-zero fm on the oscillator from the mod osc and it changes the sound towards something else (in that case a string sound) - that was kind of a surprise. For mayhem it is quite cool to run the mod osc with sample+hold as wave with keytracking - it creates a very rough and unpleasant noise, that can be used in a small portion to give sounds an extra edge.

Thanks a lot!

I've been meaning to make a new thread about Partials & Discrepancies, so this can go back to being a thread about Curves & Membranes (sorry all for high-jacking it...). Mainly as there are some undocumented features, and I already gotten some good feedback with ideas on further development of it. So it could be good to have a separate subject about it... But it's been totally bananas since the launch yesterday, mainly with the new free plugin (binaural modulator). I hope to get to it this weekend, if anyone else likes to do it before, feel free to do so. ;)

All the best,
Rasmus

Had to start that thread. I hope you like the title... (I could change it to your liking...)
I love that approach to additive...

I dunno if this is really the right thread, but it is kind of the official Unusable Engineering thread...

A new update is out for Harmonic Dissector.

This is v1.2.0, and the main thing here is motion. The interface has grown with an extra section at the bottom, but the sound itself is exactly the same.

Release notes
  • Added randomization of both sections (not affecting filter response, but following the slew setting)
  • Added the 4-slot “slewed preset” system from the Geometry series
  • Added clocked stepping of slots via internal or host clock
  • Added ability to turn off slots by double click or shift click
  • Added copy and paste function, to make it easier to align the 4 slots
  • Added value labels for LFO rates
  • Brightened the interface and increased contrast to make it more usable on low-contrast screens
It might not sound like a huge update on paper, but I found that it opens the plugin up to a lot more range.

Just by changing panning or level between slots, you can get into tremolo and auto-pan territory. Since there are two parallel filter sections, it can also go a lot further than that. You can of course create stepping or sweeping filter effects too.

One tip if you want some extra fun: run the LFOs at audio rate and modulate the depth of FM and BandWidth per step.

If you already own Harmonic Dissector, you can grab the update on your account page:
