I’ve done some audio demo of the Harvestman Hertz Donut as a “standalone unit”, the audio path is just Hertz Donut and A132-3 VCA , no filters, no efx!
The only modules used to control the vco and the vca are a MFB ADSR on the VCA and a Plan B Model 10 on some sounds to control fm amount and wave discontinuity on the hertz donut.
The Hertz Donut is a voltage controlled digital dual oscillator that can provide sine, saw, tri and square waves on both the generators and a ringmod for the square waves.
The oscillators can work synched together in some different modes :

• No Sync
• Bad
• Worse
• Stupid
• “strong” Sync

As you can imagine except for the No sync option the other sync options go from a classic perfect sync to a bad , worse or even “stupid” wich forces the second oscillator out of sync in random ways, shifting the sync point .

The idea behind the Hertz Donut is to get a Zero-FM oscillator using a Primary (the first oscillator) and a MODULATION (second oscillator) with different kind of sync and modulation capabilities over Frequency , Wave Shape and AMP.
Frequency , Shape and AMP are the possible destinations of the modulation oscillator, the Hertz Donut is indeed a simple 2 operator FM & AM generator!

This is just a short demo of the Cwejman VCO2RM thru the STG Soundlabs “Post  lawsuit ” LPF filter.
The VCO2RM is set on the middle wave (the modulated TRI) modulated by the VULCAN MODULATOR by Livewire.
Each VCO has its indipendent modulation rate.
The 2 vco are mixed by an A138 and then pass thru the STG LPF.

An A145 modulate (sine) the filter frequency.

The filter has 75% resonance and the frequency is between 5-6.

A demo video from the “AutomaticGainsay” channel of the rare Korg PS-3100 (1977)

A short documentary of studio techniques composing the soundtrack for “Infamous”.
It’s amazing how the unconventional use of acoustic instruments or simple objects can produce such wonderful and previously unheard sounds.
The soundtrack is by Amon Tobin.

Waldorf  Microwaves are top wavetable synthetizers, they are the direct descendents of the awesome PPG WAVE.

Analizing the two models (assuming that the XT is an enhanced version of the 2, but it sounds the same) the most important difference is the fact that the Microwave 1 is a hybrid synth with digital oscillators with VCF and VCA (so an analog 24dB lowpass filter for each voice and a vca) while the Microwave 2 is a fully digital DSP synth.

The differences are evident, the microwave 1 has a more organic and warm sound, sound heavier in the mix and is darker, the microwave 2 is more versatile as the synth has multimode filters, a cleaner sound and a lot more functions, but it sounds colder.
One thing to notice is the envelope clicking.
Both the 1 & 2 have env clicking, but while the 2 can be prevented from clicking with a well programmed env curve, on the mw1 the attack clicks, so this noisy attack cannot be avoided.
here is a demo comparison from Retrosound youtube channel:

The Mopho , by Dave Smith  , is a little yellow box with a very powerful synth inside.
As you can read on the manual , the Mopho is a MOnoPHOnic synth with a full analog audio path, this is the main difference with the other DSI monosynth, the Evolver.

The Mopho was born as a single voice from the Prophet 08, with added sub oscillators.
The carachter and presence of the synth is the same of the big brother but the Mopho has a plus , a more powerful bass because of the suboscillators.
The synth structure is simple: 2 DCO with subs(1 oct down, 2 oct down) , the classic DSI Prophet Curtis lowpass filter with 12/24 dB slope 3 LFO, 3 ENV with delay.
There are no effects , but the synth has the Feedback to sound more raw and aggressive.
Another interesting function is the Filter Audio Mod, in simple words dco1 can modulate the filter frequency creating FM sounds, very interesting when the filter is near to self oscillation.

As all the other DSI synth the Mopho has a 4 track motion sequencer that can control every parameter you want, in order to create, sequenced phrases, evolving textures or powerful rhythms.

The last interesting thing is the Audio in to process external sources thru the synth engine.

The mopho has  a different layout from the other DSI products, it has ten knobs with 5 of them assigned to classic controls as pitch, filter cutoff, resonance, attack and decay/release (useful for a realtime tweaking without getting into menu)  and 4 are “assignable parameters”.

The editing on the machine isn’t super fast as you have to scroll the menu, but if you get into it , it can be quite easy, however using the free editor making a patch is really fast and simple.

The strenghts of the mopho are the powerful sound, the 100% analog timbre that reminds the Sequential Circuits Pro-One , the realtime controls and the dimensions, and not to forget the Price!
The down side is the editing on the machine that can be overlooked by the ones who like software editing or who use an external controller/programmer.

The Mopho is a good machine for those who are looking for powerful analog monophonic sounds for classic tasks as bass or leads but is also a good machine for who is working on more experimental sounds thanks to the motion sequencer and modulation capabilities as the fm filter mod.

Toshimaru Nakamura presents his last work , “Egrets” , describing his way of making music thru feedbacks.
A kind of music that’s not rapresented by harmonies and melodies, but just “noises”, or “Sound itself” that can be music…
This is “onkyo”…

An Elektron Monomachine “alone” song!
The Monomachine can handle very well the melodic and rhytmic duties together even with ony 6 note polyphony and six track sequencer…

This is a great sounding filter!

This is a glitch/random bend by Finlay Shakespeare  http://www.futuresoundsystems.co.nr .
The mod was originally done on the casio sa1 but it should work with all the sa-serie.

Here is another random/glitch mod I found in a couple of forums:
