Thanks Ammar! Yeah I love GrainShifter, cool thing. More grain processing is planned for the next updates...

Happy holidays too!

just LOVE IT!

The amazing features, the amazing synth!

http://diversion-synth.com/DiversionSetupWin.exe

Here is a list of changes:
- Exponential and variable slope envelope modes
- 2 analog lowpass filter modes
- Filter parameter DMP renamed to Control. Now it works for each filter mode, except 6 dB lowpass. See the manual for details
- Hyperbolic shaper type
- Feed, Erose and Chip Oscillator Effects. Oscillator Effects are selectable now
- GrainShifter FX
- 2 tube modes for Distortion FX
- Crackles LFO mode
- Redesigned BUS Distortion
- 6 additional slots for ModMatrix
- Fixed occasional crashes
- Minor fixes for ModMatrix, Master Level range, pitch modulation, Scissor and LO-FI modules, GUI and many others
- Added 50 new patches
Let me explain several features. The update intended to expand Diversion in two dimensions. The first part is analogue sound design. Now Diversion has two fat analog modelled lowpass filters with an adjustable internal saturation. From the first look it may seems that these filters produces too strong self-oscillations for high Resonance values. Just tweak internal saturation and you will see it worth that. The second point is new envelope modes. Actually, in EXP mode EG produces more complex envelope for Decay and Release stages than exponential. This curve has more natural fading out and distinct "punch" than a traditional exponent. Variable-slope mode is useful for achieving linear and Bezier-style curves. Finally Diversion now has a fat hyperbolic shaper and tube models for Distortion FX.

Don't forget to try CTRL value field for different filter modes. For example, internal resonance limiting circuit with an adjust threshold was implemented for classic LP/BP/HP filters. Bandwidth, balance, resonance, center frequencies can be controlled for other filter types.

On the other side the update extends atmospheric, FX and LO-FI capabilities of the synth. New GrainShifter FX can produce many cool ambient things. CHIP OscFX is a great addition to BUS' LO-FI. Try it at max low and high pitches, apply it to waves with a low and high harmonic content. FEED FX is great for shaping noise waveforms, producing digital aliasing and extending traditional FM capabilities. BTW, it makes sense to use two and more similar OscFX within single oscillator. OscFXs are smart. For example, if you use two SubOscs then transposition for the first one is one octave below original pitch and two octaves for the second one. And so on…

There are 50 new patches included to show usage of new features. If you want to check only those new patches you could download them from here:

BTW, if you haven't noticed yet, Diversion wins two Computer Music awards in CM173 - Editor's Choice and Performance with a score 9/10.

So have a fun, happy Xmas and New Year!

Great update for a synth who was already very interesting !

The filters are so good.

I have my sounds all things new.
Dmitry it's Christmas, and they give us an Easter egg.

Thanks guys for support!

BTW guys, I forgot to mention, did you enter Computer Music competition in CM173? You can win one of 8 copies of Diversion. More information you could find here http://on.fb.me/cmcomps. The thread's head updated.

That's a good idea to get more attention, Dmitry. All the best and Merry Christmas!

I almost missed the new CTRL feature! Woah! * wipes tears of joy*
Funny how you can use one or two controls to totally mash a standard waveform beyond recognition and then have so many left to play with! You can even tame it back with for instance chip only to bend it away with the scissor again

Then you enter the filter ... The FM, The Bus filters, Dist, Lofi .. and maybe into Bus 2 .. and now we have a grain effect lol

Thanks, it's great that this update isn't fruitless!

Now when you can pick your osc modifier (if that is the name) you can stack for instance four scissors

Those dubsteppers will adore this vsti

I was wondering.. is it possible for the vsti to know when aliasing occurs? It would be handy if a little lamp flashed so you knew when to try 4x or 8x. With all the weirdness going on in a patch it can be hard to detect it but if you switch to 8x suddenly it all sounds so much more pleasant. Maybe the trick is to start at 8x and once done try out 4x and 2x.

This would be a great feature, but it is hardly possible. For aliasing prediction it is needed to estimate signal spectrum in several points of the synth and take into account all modulations for key parameters. This algorithm would be too smart, complex and not enough reliable. It requires a lot of additional, useless for synthesis information, which wastes CPU.

However, here are several guidelines to keep track of aliasing. VST spectrum analyzer is the best tool for monitoring aliasing. If you are looking at analyzer during the preset making you can notice when aliasing occurs. Typically preset's spectrum evolves smoothly with its growth. You can recognize aliasing as a fast spreading, breathing pollution. Like this:

In Diversion there are several modules which can produce aliasing. FM/RM, Feedback OscFX, Drive after filters with a high resonance setting, Filters with an internal saturation, Distortion FX. Aliasing in LO-FI modules and Chip is a normal part of the process due its nature. Oscillator waveforms, other filter types, most of OscFXs, all FXs except Distortion are alias-free.

Typically, you should care about aliasing only when you tweak FM knob and Filter's Drive, which applied after filter with a strong resonance. The most of other cases does not produce any reasonable aliasing. However, sometimes you can make highs clearer at 8x. For example, sample rate reduction, comb filters in some cases can sound much brighter at 8x. So sometimes it would be great to try different oversampling options.

You shouldn't use oversampling for all other cases - typical and simple basses, pads, plucks. Oversampling doesn't improve these kinds of sounds, it simply uses a lot of CPU for no purpose. And finally, good practice is trying to use oversampling only for monophonic sounds. In this case CPU overload is mostly unnoticeable.

I can"t win anything in CM mag cause I am in South Africa...will have to save up for this Baby "Diversion"

TB4C · Post by **TB4C** » Tue Dec 27, 2011 8:06 am

I'll make demo tunes if you want Dimitry....I'll wash your dishes, your car, I will work in your garden for one of these!!!

Yes, unfortunately CM compos only for US/UK citizens

I'm really sorry. I have shoot PM to you.

Big update for Diversion
