@TomHawker7 No solution needed. Presets from 2.7 work just fine in 2.8!

Founded in 2001 by industrial designer and synthesizer fan Urs Heckmann as a one-man show, the Berlin-based audio software company u-he has since evolved into a tightly knit team of employees, active associates and 3rd-party contractors – with ambitious plans.

Known primarily for Zebra2 and Diva, u-he has released several other successful products over the years, and has contributed freeware plug-ins to popular music technology magazines. Despite their underlying complexity, u-he synths and effects are widely acclaimed for their ease of use.

The u-he team has been exploring new technologies for vastly improved analogue synth and delay emulation, as well as various "physical modelling" approaches to acoustic instruments and effects. All valuable groundwork for the Zebra3 project and other spin-off products - watch this space!
Especially well known for the Zebra2 and Diva software synthesizers, u-he has developed several other successful products over the last decade, and regularly contributes freeware to popular magazines (available as download or on cover discs).

Despite their underlying complexity, u-he synths and effects are widely acclaimed for their ease of use. This is often attributed to Urs Heckmann's background as industrial designer. Heckmann sees the seemingly unconventional decision to start an audio software company as a direct result of his equal love for industrial design and for synthesizers.

Most recently, u-he has been exploring concepts for analogue synthesizers, and the first results can be heard in the software synths ACE / Bazille (audio-rate modulation paths) as well as Diva, Presswerk and Satin (accurate simulation of electronic circuitry). Hive is u-he's first foray into the world of low CPU dance-oriented synths.

The fourth in our series of bite-sized tutorials aimed at users of u-he's Diva, this one is all about the ever-popular "pulse width modulation" (PWM) effect. PWM was traditionally used to add tonal movement -- especially useful for synths that only had one oscillator e.g. ARP Axxe.

Act I - standard PWM: How to set up typical cyclic PWM in the various oscillator models. The ratio between the upper and lower levels ("mark space ratio") of a rectangular waveform is slowly modulated by an LFO. Note: One of the sawtooth waveforms in the "DCO" oscillator model also delivers a similar effect, but I neglected to demonstrated it in this video!

Act II - the very first PWM is likely to have been an attempt to emulate the satisfying "zippy" sound of two detuned sawtooth waves, one of which is inverted. Because the Triple VCO model features a Ramp wave (i.e. inverted sawtooth), it's worth trying this out in Diva. A taste of history, this method is my personal favourite.

Even if your 2-oscillator hardware synth didn't have a ramp wave, you could still make similar sounds by detuning two pulse waves - as shown here.

Act III - "sync" i.e. oscillator synchronization means that the phase of a slave oscillator is reset by a master oscillator. If you modulate the pitch of the slave within a very narrow range, you can get effects that are very similar to PWM. This method requires some practise...

Homework: how dense can can make your PWM sound by stacking and detuning 2 voices (no more), and using the Voice modulator to offset pulse widths and even the LFO rate? Read that again...

Hi u-he, .

I am having problems with Diva. It keeps telling me that it has problems with permissions and it is unable to write the files into the diva folders.

I have already tried all the solutions in this forum and yet it still does not work. I've already tried installing it out of Program Files and granting full permissions to the Diva folder but the problem still persist.

Please help.
