Synton , Syntovox 223:
- Rumours say that this vas Syntons
last vocoder before they went under.The vocoder
vas
designed to be programmable and to alow each BPF
channel to be swept in frequency and in Q value,
but all this info are still rumours.

Doepfer A-129:
- Made in conjunction with Florian
of Kraftwerk. 15 channels 13 band pass 1 high
pass
1 lopass.This is Dieters modular vocoder for use
in his modular syntheziser system.
You can off course use it as stand alone but then
you need a separate box and power supply and some
cables.The A129s vocoder are reconfigurable so
you can use slew limiters and other modules, 24dB
BPF.
a acceptable price for an analogue vocoder...also
for the asking price you can crosspatch the BPF
filter
channels as a standard (wery good).
Additional info by Dieter Doepfer:
Our collaboration with Kraftwerk started many
years ago as we made some special designs for
them
(e.g. the miniature keyboards the use on stage
for Taschenrechner/Pocket Calculator and a
special
phonetic keyboard for voice synthesis).
The first unit we built in cooperation with
Florian Schneider was the MAQ16/3. We built some
prototypes and
Florian tested them and told us what we would
improve and which features are not required.
So we went many times to the Klingklang studio in
Dusseldorf until the final version of the MAQ was
complete.
A similiar cooperation - but not as close as with
MAQ - was made for the SCHALTWERK .
The next scoop, was the A-100 vocoder. We tested
all of the vocoders of Florian (and that's a lot)
and compared them
to our A-100 vocoder prototypes (the first
versions with different filter designs in
quantity and filter response types, e.g.
10 band passes, 8 band passes and high/low pass,
13 band passes and the final version with 13 band
passes and
high/low pass). And so we found a very good
compromise between price and sound.
Even the very high priced vocoders sounded not
significant better than the final A-129. But we
learned a lot
about vocoders e.g that a treble boost of the
incoming speech signal is very important for a
good vocoder effect
(is now included in the A-129-5). All high priced
vocoders imply such a treble boost but the
customers is not
aware of this detail as there is no remark in the
user manuals. We experimented together with
Florian with a
32 band graphic equalizer to find the best treble
boost for good speech recognition and implemented
it into the
A-129-5.

Zoom 1205:
- 10 channels, effects processor. 2
parameters adjustable ,some sort of decay and
softness
parameters. sounds OK.But limited variation on
the sound .Mic amp can be used with a dynamic mic.
|
Zoom 1201:
- 18 channels, effects processor, 16
types plus a variation knob, most interesting
unit since it's low price 99UKP only.
Some test reports from music magazines says that
the 1201 sound very good. (I will give this one a
try in my setup.)
Finally i have purchased the unit (1997 summer)
and can report that it does not sound too good,
it lacks sibilance and
channel separation is not the best, the unit does
sound but not god or bad so to speak , it lacks
character on the filters.
For example, S/KK/B/P consonants are not well
vocoded! Nevertheless you get a lot of very good
delay/phaser/reverb
effects whit this unit and its cheap toooo!!! But
as a vocoder, naaa!
|
Roland SE70:
- 10 or 21channels, stereo, chorus,
reverb delay at the same time as vocoder, digital
Effects box besides vocoding,
Sounds very god. sweet sounding . Buy one if you
can get one!.
|
Roland SE50:
- 7 channels , effects box are god
but the vocoder algorithm are crap! Not
recomended for vocoding.
(i have one for many years now, mainly for reverb).

Korg WaveStation AD:
- Digital, Mic input, a vocoder in
the effects unit of this vector synth, sound god.

- Korg MS2000:
Part of the new analogue modelling synth MS2000,
digital implementation of the VC10 says Korg.
Well?

DSP DIY:
- Vocoders today are Texas
instruments TMS320cXX series of DSP's and
AnalogDevices Shark DSP, this is
very powerful dsp's and are mainly obtained in d-i-y
form and you have to apply the software on your
own, no ready made unit yet. Hopefully some one
with the programming skills are making a super
vocoder/harmoniser/format shifter/realtime
allophone synth, then we all can put those old
analogue vocoders to sleep.For example the SHARC
dsp have power to do a real time vocoder with a
minimum 50channels and approximately around 88-93dB
filters and that with super sharp corners on the
filters.And also they became programmable with
memories and midi ....unt so veiter.....

Kyma:
- For the Kyma DSP computer,77
channels and millions of special functions, new
for 1997, look at Symbolic Sound.
This vocoder are a algorithm/program module that
runs on the Kyma system. Motorola 56002 DSP's,
this system
can do any synthesis method that you can think
off. Please look at Symbolic Sound web page for
more info.

Casio VA10:
- 6 notes vocoder, pitch shifter,
headset mic are included , strange instrument ,
not many countres in europa imported
this machine. A sort of mini home keyboard with
strange vocal effects, buy one if you can get one.
|
Clavia:
- 16 channel vocoder algorithm,
module for their Nord Modular, software version 2.0.
,hipass bost , patchable between
modulator channels, included as a module in the
new µNord. I have listened and patched up one
and it sounds OK, but
i was not impressed on the number of modules you
had to patch up to get a resonable sound!
|
VOOX16:
- 1996, DSP/software based, DSP56001,
the first software vocoder i have seen. It's a
program running on the AtariFalcon030, its 16channels,
stereo, matrix panel for cross ptching of the
filters in a million ways like the EMS5000 unit
envelopes on each channel with a time parameter
for each channel, a panorama controll,you can pan
each channel,
16 chanel output mixer a level parameter,slewlimiter
control, freeze/ slow/fast/ a spectrum analyser.
A par of VU meters, its programmable too,it cost
980skr inc tax, since it's running on a computer
it has a nice graphical
interface, mic input and line input . It would be
great to hear it in action. Some people that have
tested this unit ,say's it
sounds great!

Cyclonix:
- A software program running under
WIN95, 18 channels each channel have volume, pan
fader.Inbuilt pitch tracker for
the voice input, a pitch shiftert,internal
oscillator generating pulse and various chord
waves. The filters are all
implemented as 8th order (48 dB/octave cutoff)
Butterworth digital bandpass filters having a
selectable bandwidth of
either 1/6, 1/3 or 2/3 octave. The centre
frequencies, (rounded to the nearest Hertz), of
the filters are as follows:
108, 137, 172, 217, 273, 344, 434, 547, 689, 868,
1093, 1378, 1736, 2187, 2756, 3472, 4375, 5512
Noise generator and a wav playback generator for
the carrier,possible to save vocoded sounds onto
hard disk.
A spectrum display showing the vocoded energy(modulator).
A V/uV detektor applying noise to the signal for
unvoiced speech..
This vocoder are most for tooling around since it
suffers from signal processing latency on slow
computers
(tested on my P133) and it using only 16 bit
dynamics and 11,025kHz sampling rate that
quantising noise audible.
Never the less, it would be to great fun for
people who are doing vocoded sounds for their mod
player and that kind
of stuff...Nice graphic user interface tooo... If
this software had been implemented on a DSP as a
stand alone product
instead of running under WIN 95 it would have
been a splendid vocoder.
Tested 1998-08-31 on a P133/16Mb/Soundblaster32.
