Each envelope can be either polyphonic or single trigger. This is especially interesting with the monophonic voice allocation, as the filter envelope can be set to be triggered only by the first note(s) while the Amp Envelope is triggered anew (i.e. on each note). Think "organ percussion register", for instance.
The Envelope types include the standard ADSR as well as an enhanced ADSR-variant (with controllable attack level and two decay and sustain stages), two different loop envelopes and a "one shot" Envelope.
The Loop types can be used to act as additional LFOs, while the One Shot is perfectly suited for percussion sounds (which typically ignore the note release).
Each of the three LFOs offers sine, triangle, square and sawtooth waveforms, plus sample & hold and random.
LFOs can be synchronized to MIDI clock, they can be polyphonic or monophonic, reset on key trigger to a freely definable phase, and the speed can be scaled by MIDI note (key follow). There are separate delay and fade in/out parameters for e.g. delayed vibrato (positive Fade values) or a burst of vibrato at the start of each note (negative Fade values).
One important feature of the Blofeld LFOs is that higher rates reach well into the audio frequency range, thus making them useful extra FM sources. There are two basic modes: either linear FM as seen in classic digital synths, or logarithmic FM, which is primarily the domain of analog modular systems.
Here's where the real Waldorf power lies. Each and every instrument designed and built by Waldorf lets you connect dozens of modulation sources to all the important sound generation parameters.
Individual or multiple oscillator pitches, their pulsewidths and waveforms, their levels and filter-balances, FM modulation amounts, individual filter cutoff and resonance, filter FM amounts and stereo panning, or just the good old sound output level – everything can be controlled from internal modulation sources or from a variety of MIDI messages such as velocity, keytrack, continuous controllers (including wheels, breath and foot controllers) etc.
You can of course "modulate the modulators" i.e. control LFO speeds and individual envelope rates and levels. But in Blofeld you can even specify that these sources modulate themselves – recursive modulation! For instance, modulating an envelope rate by the same envelope (or another one) can alter the shape of the slope dramatically from the standard exponential curve to linear to inverse exponential.
And how many slots do you get in the mod matrix? Two? Three? Four? No, we're talking big here. You get 16 freely definable slots plus all the pre-routed modulation destinations such as pitch, Osc 1, 2 and 3 frequency and PWM (pulse width modulation), filter 1 and 2 cutoff, panorama and amp level modulation. And let's not forget that the filter envelope is already routed to filter 1 and 2 cutoff, and the amp envelope is routed to the amp level. Makes a total of 33 simultaneous connections if we counted correctly.
What if you want something really really crazy, like controlling a pitch vibrato done by LFO 3 with the modulation wheel. Although there are a few such composite modulation sources such as "LFO1*MW" (LFO 1 controlled by Modulation Wheel) and "LFO2*Press" (LFO 2 controlled by monophonic Aftertouch), there's nobody doing the "LFO3*MW" thing for you.
But, don't worry, that's where the Modifiers come into play. In seconds you can set up a new modifier, with the two sources set to LFO 3 and modulation wheel, and the "operation" set to "*" (multiply). You can use such custom-made modulation sources in any of the modulation slots described above.
Okay, maybe you are more the regular musician who simply wants to perform a binary OR between two modulation sources? Okay, go for it! This operation is just one of several at your service.
It features variable clock divisions from 1/64 triplets to more than 1000 bars, with variable swing/shuffle, a range of up to 10 octaves. Up, down and alternate figures, selectable play order from low to high note, low to high velocity, as played or reversed, variable note length, different velocity modes. And Hold or One-Shot, if you like.
But more importantly, it has the most powerful Pattern Editor we have ever seen.
You can set each Step to either play the note it would do so anyway, to pause, to play the previous note again, play the first or the last note, play those together, play a chord consisting of all held notes or a randomly selected note.
Then you can adjust the Accent of each step (including silence), activate or deactivate Glide for each step, set the timing to play a step ahead or behind its nominal time, and finely adjust the note length between short staccato and full legato.
No wonder this arpeggiator had great reviews when it first appeared in the Waldorf Q. It will take you straight to arpeggiator-heaven, as has already happened to thousands of Waldorf customers. Dig it!
