The final version of the Pulse 2 contains several additional Osc waveshapes.

This is copied from page 19-21 of the manual:

The following shapes are currently available:

• PWM (only OSC 1 and OSC 2) selects the pulse waveform. This waveform produces a hollow / metallic sound. If the PWM waveform is selected, the
parameter Pulsewidth is used to change the pulsewidth of the waveform.

• SQR (only OSC 3) selects a square wave with a fixed pulsewidth of 50%.

• SAW selects the sawtooth waveform. A Sawtooth wave has all the harmonics of the fundamental frequency in descending magnitude.

• TRI selects the triangular waveform. The triangle mainly consists of the odd harmonics with very low magnitudes and sounds close to a sine wave.

• APW (only OSC 1) means "Alternate Pulse Wave". The positive effect is that you get PWM like sounds but with constant energy, at the cost of having to tolerate a subharmonic one octave below.

• UNISON M (only OSC 1) creates an unison in mono mode by using a cluster of eight pulse oscillators at once. So if you play a single note, all eight
oscillators play this note, slightly detuned to enrich the sound. Detuning (UNISON DETUNE) can be controlled with Keytrack.

• UNISON P (only OSC 1) creates an unison in polyphonic mode by using a cluster of eight pulse oscillators. If you trigger one note only, all eight oscillators will be played with the same root pitch.
If you trigger eight different notes, every oscillators plays its own pitch. Detuning (UNI-DETUNE) can be controlled with the Keytrack parameter.

• UNIAPW M (only OSC 1) creates an unison in mono mode (same as UNISON M) by using a cluster of eight APW oscillators at once.

• UNIAPW P (only OSC 1) creates an unison in polyphonic mode (same as UNISON P) by using a cluster of eight APW oscillators at once.

Keep in mind: If one of the Unison shapes is selected, the Keytrack parameter controls the detuning of the poly pulse oscillators.
w If one of the Unison modes is selected as Shape, you cannot use OSC 2 and OSC 3. Both oscillators are not accessible then.

• Para-8 (only OSC 1) creates a special paraphonic mode where all eight PWM oscillators sound with frequencies according to the held notes. So if you
play a chord with up to eight notes, that chord is played by the oscillators. In this special case, the the Keytrack parameter controls the fading of the
pulsewidth modulation. The rate also depends on Attack and Release of the amplifier envelope ENVA.

Keep in mind: If Para-8 is selected as Shape, you cannot use OSC 2 and OSC 3. Both oscillators are not accessible then.
Keep also in mind: The signal path of the Pulse 2 is mono. All eight voices need to use one VCF and one VCA.

• Para-4 (only OSC 1) ist he same as Para-8. But two oscillators per note are used. This will reduce the polyphony to four voices. You can set up pulsewidth, pitch and fade individually.
w Keep in mind: When Para-4 is selected as Shape you cannot use OSC 3. This oscillator is not accessible then.

• X3-PWM (only OSC 2) creates a PWM crossmodulation. Crossmodulation is a XOR combination of the waveshapes of OSC 2 and OSC 3 which can be used for creating very complex sounds with unharmonic frequency proportions.

• X1-PWM (only OSC 2) creates a PWM crossmodulation. Crossmodulation is a XOR combination of the waveshapes of OSC 2 and OSC 1 which can be used for creating very complex sounds with unharmonic frequency proportions.

Although Oscillator 1's or 3's square waveshape is used for crossmodulation, it does not mean that this square waveshape must be used as the source signal. Because the crossmodulation is purely internal, you can select another waveshape
for Oscillator 1 or 3 if you so desire. Please note that you can also modulate Oscillator 2's pulsewidth at any time. Additionally, you can switch
synchronization on and off independently.

• EXT (only OSC 3) switches off OSC 3 and enables the external audio input for routing its signal through the Pulse 2 synthesis path.

Please keep in mind, that an incoming signal can get to the output section only when the VCA envelope is triggered or the VCA is open. This means that the volume envelope ENV A has to be started by an MIDI note. This can be achieved
by playing on a keyboard or by activating the built-in arpeggiator.

• FB (only OSC 3) creates a feedback from the drive output back to the mixer. Depending on the filter settings this can create interesting resonance effects
that cannot be realized with the regular Resonance parameter.

This is nice news. No sine wave btw?

No sine with the Oscs, only with LFO1 + LFO2 or if you use self-oscillation.

silly question, that's not answered directly in the specs:

Monophonic or polyphonic?
how many voices max?

Monophonic AND paraphonic. Look at the list of Osc waveshapes i just posted.

Paraphonic waveshapes are: PARA-4, PARA-8, UNISON-P, UNIAPW-P

I just added the waveshapes list to the "reserved" post below the first post of this thread.

Thanks. Hope the unit arrives soon so I can figure it out.

Actually that was already know since around a year but the Unison and APW modes are new...

For additional informations about the Pulse 2 the manual is available here (link also added to the OP):

Seems to get better and better.

Also cv and gate added. Nice features!

Don't think I've seen a hardware synth announced in KvR news before

Just seen to too. That's new indeed...

Lol page 10 of the manual: "Do not leave your Pulse 2 near children, mothersin-
law or pets. This could lead to critical interactions".

The featurelist is great and the price is fair, it is rather tempting

!
Is the output volume louder than on the Blofeld ?

it turned out today that the Waldorf Pulse 2 analog synth seems to be officially released now.

Here are links from the Waldorf website and the Waldorf Music facebook page:

https://www.facebook.com/WaldorfMusic

The Waldorf website also includes a few audio demos (in the player at the right border of the page).

The Pulse 2 manual (in german and english) is available now:

I participated as a Beta tester and factory sounds designer and will try to add more infos and audio demos ASAP.

Ingo

you started a new thread just to talk about your involvment in the synth?

wow

Mods, do we really need two threads about the same subject? No. Lets get this one locked shall we...

Waldorf Pulse 2: officially released (OS updated to v1.18)
