Roland JD-800 has 2 per part, so 8 LFOs are possible when using 4 oscillators.

well, the Machinedrum has 16 freely assignable LFO's that can be assigned to any of the 16 tracks, meaning you can easily dump 8-12 LFO's on one part if you want to.. not anyones first choise of synth tho, but still pretty nice

Kurzweil K2000 has a bunch of lfos, loop able envelopes and FUN generators which can be used similarly. Korg MS2000 has but 2 true lfos, but a 3 step mod sequencer which can be used as 3 synched loopable lfos.

<offtopic>
Honestly, if the MS2000 didn't sound so damned metallic it would have stayed my main synth. It has a surprisingly flexible mod matrix considering how easy it is to use. Very Evolver-esque in a lot of ways. However, I only pull it out these days when I want something explicitly digital sounding.

command station has 15 different types of LFOS. Having 2 of them per voice inside a patch. A linked single patch can have 12 instruments so it can contain 24 LFOS,

those LFOs can be routed one inside another, or the variation of LFO1 can control the speed of variation of the LFO 2 or viceversa, can be smothered with lag processors, or you can mix them with white or pink noises, reverse them, delay their entrance sync with tempo.

Also, two different LFOs can become one, linking them inside a SUM lag processor, and then, being sent to any destination.

Also, there is an extra section in the list of patch sources on the modular section known as clock divisor, wich acts as a primitive LFO, with clock16th, clock8th, clock4th, clockhalf, clockwhole, etc....

... is a shame it's so slow, because possibilities of modulating LFOS on the EMU are endless

Yeah, the modern E-mu P2K-based synths have crazy possibilities as it concerns LFOs, just as balma described.

The Clavia Nord Modular can have many LFOs in a patch, or you can use the LFOs for synthesis. You can also build your own custom LFOs from other parts if you so desire.

While not a synthesizer in intent, the Eventide H8000FW can have oodles of LFO modulation in a patch.

Alesis Fusion has 8 lfo's and 8 envelopes.

Just as important as the number of lfo's though, are the number and type of shapes those lfo's can produce.

I forgot about that one...

One important point is that the LFO's shape can be modulated, which is great.
The only minus when compared to the Ion is that you can't get different shapes from the same LFO... you must use different LFOs to get different shapes.
But given you can modulate the shapes like if it was an oscillator and you get 8 of them... I'd say it's not bad :P

Is a shame is so slow, I think that even Aaron Appolito (one of the CS programmers) mentioned it as a failure. On most of digital synths, you have 127 possibilities for speed, but on the modern protean romplers there are only 25 possible velocities for an LFO on the non-tempo synch mode.

But there's a gateaway from this frustrating limitation: patchcords.

LFOS can be modulated in very intrincate ways with the patchcords. The parameter "variation" on each LFO is pretty interesting. If you add variation (0-127) the harder you press the pad, the wider the oscillation of the LFO will be.
Also, LFOs can be routed to almost any parameter existing inside the engine. There are such crazy LFOS, that carefully programmed, can be transform a flat and simple pad into an arpeggio with multiple notes, just moving one knob.

So the LFOS are static on velocity, but very dinamic when combined or smoothed by processors before being sent to a filter envelope. Combined with a third source as Clock divisors, now alternatives that cannot be reached by common romplers appear on the horizon

You can even program 16 knobs exclusively for only LFO changes, and still missing more possibilities.....

The OASYS MOD-7 FM Synthesizer has 5 LFO's per voice, and is 52 voice polyphonic = 260 LFO's. So it has true 'polyphonic LFO's'. Though you set just five sets of parameters, they can be made to respond differently on a per-voice level, as for example when you make the LFO's key-velocity sensitive. For example, if LFO-1 is set to vibrato and is set to be velocity sensitive then every note played will have a vibrato (rate or depth) related to the key velocity. So its unique to each note played and is very expressive. It gets even wackier if one LFO is set to modulate another one - meaning that you have, per voice/note, control over very sophisticated modulation.

A lot of synths, sound modules and soft-synths have polyphonic LFO's but the OASYS synth engines are all massively equipped in this department.

and now for something completely different:

the Jupiter-8 has one LFO.
(the 2nd OSC can be set to low freq, but is only routable to osc1 frequency so it's rather wasted)
