Hum808 X.

It is a synthesizer designed to be easy to use thanks to its intuitive all-in-one interface.

The reading of the signal is possible thanks to its spectrum analyzer and
to your oscilloscope that allow us to shape the sound with great ease from a technical as well as a creative approach.

Its three oscillators together with the sampler can operate in subtractive synthesis or FM according to the configuration of each user, facilitating sound experimentation with unimaginable ranges., .

A quick example.

1., Load the Default preset
2., In master panel put Carrier freq with Osc1 - Osc2 and Mod in Sampler activate the FM button
3., Drag a sample from a bell to the sampler and activate it
4., Activate the Pitch Modulator with a 10% mix in the Envelope tab
5., Adjust modulation from -3.84 to 3.80 st in 2 steps
6., Remember to Activate the Pitch mod and Loop button
7., Increase voices, unison and spread to your liking and listen to your patch.

And to finish creating your idea you can process your sound with its 5 included effects ...

Let's have fun designing something with the Hum808x.

These are its main characteristics:

  • Additive Synthesis and FM.
  • 3 oscillators with 5 waveforms.

Excuse my English plz! It is preferable to my Spanish! This plugin, a bass and bass drum synth along the lines of future audio's sublab but free just needs a few bug fixes and missing features to become oftop line plugin I would have loved to vote for in KVR DC 21, but the problems are dealbreakers for me...mayb a post-contst fix? Key trouble is that there are zero crossing problems with the signal processing that produce loud clicks that cannot be attributed or used as bass drum clicks. I thought tweaking the envelopes might clear the problem but I was unable to get clean results even with longer attack times on the filter and the amplitude. Missing features: a noise osc, glide/glissando, adjustable pitch bend settings so that I can get my controller to work with the synth's PB. I could not get my samples working in the sampler although they showed up in the graphics, and I think I am missing simething because samples seem to work fine in the presets. The signal flow is difficult to figure without a manual. I tried watching the vids, but my spanish was not good enough. Even a signal flow chart would be welcom. It alseo seems to me likke the sample button should be up top as a tab rather than in its own space, since all the other stuff up top uses the same space.This sounds super critical but it is not---all of these are fixable and I want to encourage the dev to do so (or show me what I am missing!), as the sounds that do come through, both on bass and on bass drum, have a lot of potential, and the synth looks like it has a lot of versatility, even perhaps beyond bass stuff, but I could not get to that because of the problems. Please keep at this one! Thanks and sorry to be a bit negative.
