FAST LFOs - FAST ENVELOPES (scroll down)
- "the fast synthesizer list" providing really fast LFOs and ENVs
- all Synthesizers that have LFOs that go beyond those sloooowww boring 30Hz. where does "fast" start? well at audio speed (40-50Hz min.) well, in fact it is better to talk about modulation generators .. or even better about Oscillatores that can be used for modulation.. these days..
- alle synthesizer mit schnellen LFOs und hüllkurven (weiter unten) oberhalb 40Hz/ im audiobereich ;) - übrigens: eigentlich ist es besser von Modulationsoszillatoren zu reden,

1) fast LFO-Synthesizers ( better talk about Modulations Oscillators):

• the Korg Prophecy has four 40hz LFOs.. same as the Korg Z1
  
  the EDP Wasp has quite fast LFOs, too
  
  the Yamaha CS series.. excl. cs01@ 50hz CS15,CS30, CS40m, CS80 etc.
  all Yamaha FM Synthesizers (fixed freq. OPs moding other OPs) or the normal LFOs of any FM synth from yamaha - goes up to about <50Hz
  
  the Moog Voyager (50hz again) and of course theee LFO machine:
  minimoog, ems synthi A /AKS /VCS3 (500hz) - the "LFO" is similar to OSC3, so the ARP2600 counts in ,too and other gear like steiner parker synthacon etc. that use the 3 VCO, 3rd is mod for VCO1+2-concept from the 70ies. (OSC speed)
  
  MFB synth I+II,synth lite + lite II + poly lite .. about 50-60hz. the synth II has VCO mod/fm anyway,so it is very fast mod lfo/vco.. but the envs are the slowest I ever had..
  
  possibly the "Oberheim" viscount ob12, but do not ever think of... ;)
  
  Roland Jupiter series (4+6 at 80-100hz, ju8 at 64hz) and Roland Promars - 80hz-100hz
  and juno1/2 + mks50 also works at about 40-50hz (apprx./estimated) but the speed resolution is steppy..
  
  all Waldorf Q series incl micro Q (2600Hz)
  Waldorf Microwave XT / Xtk and Microwave 2 (100Hz)
  
  DSI Evolver & Poly Evolver
  
  Korg MicroKorg / MS2000 (ca.40Hz)
  Korg Electribe SX und MX..
  
  Novation Supernova / Nova I + II
  
  Doepfer MS404 (hi range! 5khz)
  
  Vermona Perfourmer (app.75hz)
  
  Clavia Nord Modular + G2 (ca 380hz o . OSC)
  
  Alesis Fusion Synth (app. 200hz)
  
  and most modular systems - since you can use an oscillator as LFO.. but some systems have LFO Modules with high speed such as the TMSS (theiss) or my "HelLFO" I am using in my moog (quad DIY LFO) ;)
  and the SemtexI should say SCI sixtrack ,too.. but it's range is digitally "reduced" (for its low number of steps/resolution per parameter)by looping the envelopes, you can built a very fast LFO, such as FM7 or the andromeda (the a6 LFOs are very slow, but the env's aren't)

  and some software.. ;) (FM7, Tera, etc.. not listed atm..) forgot one? tell me or post.. habe ich was vergessen? einfach posten..

2) FAST ENVELOPES - SCHNELLE HÜLLKURVEN
basics behind really fast envelopes could be: exponential VCAs and different slopes in the ENV stages - my definition for fast envelopes is: it's around 1msecs

• Jupiter 4 / Promars (one of my fave fast ZAP envs ..)
  
  Moog Modular , Minimoog, etc. (to my ears one of the nicest and ultrafast ZAPPing Envs ever made, maybe because of it's behaviour from max. level to sustain.. somekind of "hold" and fall sounding very snappy!)
  
  a new very very fast Envelope Machine is here: The Cwejman S1 from Sweden.
  it has very scalable fast envs with 0.5ms response time. sorry, this one kicks! should kick of almost any other analogue synth I know atm.
  
  there are quite some SH rolands with nice envelopes, too.. but note: those AR ENVs of ARP or SH5 and other models never sound "fast" for other reasons.. if you want it snappy, you need at least AD or more..
  
  Andromeda A6 set to ultra fast in the "engine optimizer" 
  
  Analogue Systems Spawn (why? = VCA exp, the ENVs themselves are not really "fast"..)
  
  Technosaurus Modular System provides very nice snappy envelopes!
  
  also Clavias Synthesizers are quite fast, but it sounds "digital fastness" (same for a6)
  
  quite nice: Waldorf Q / µQ Envelopes.. same thing about digital envs, you can still hear it is different.. but not bad.. same for access virus series..
  
  not on top of everything but interesting are those env's in yamahas FM synthesizers, especially TG and DX series..
  
  some links: http://analog.no/
  but do not take this too serious, the jx10 1ms? I did not have the impression of ultra-fastness on the jx8p, jx10 ;)
