I always wondered about that too. I've never heard that in any recordings of the Tri-stereo. It's because in the preset, the rate is extremely slow unless you activate the virtual "Rate jack" (it's down to 0.025hz for chorus 3 and 4), also there is no minimum delay time. When the rate jack is on, the rate is 3.02Hz for chorus 1 and 2, and 0.302hz for 3 and 4, and the minimum delay time is around 7.5ms.
So, are you saying that it's kind of a 'user error' to use a delay time this low and the block is not made to 'work' with minimum delay times like here ? I guess if you increased the delay time a bit you could get rid of the 'slapback' (haven't tried it yet), but then again, that would affect the overall tone and would move us further away from sounding like a Tri again... :?
It's more down to the rate. The rate is just too slow for 2 of the delay lines. I think that when it is that slow, we don't percive it as much as a chorus effect (with the pitch going up and down and it being part of the original signal), but just a moving delay with changing delay time, which goes from being equal to the dry signal (because we have no minimum delay time in the chorus), to a slapback.
Also, every chorus unit that I know of, that you can't control the delay time on, have some minimum delay time. Usually, they are between 5-15ms. Personally, I don't think the rate jack on the Tri would change the minimum delay time. From the statements and user descriptions I've gathered, it only changes the rate. I've also added the manual at the end.
The Sound Quality of the Tri Stereo Chorus is amazing, no other unit
can even touch the sound of the chorus this unit produces. Its like
liquid, very thick. It features on the front panel 4 knobs, 3 of them
are to control the 3 chorus's left, center, Right the 4th knob is for
the rate. There are 5 push bottons also on the front a db pad button,
a Effect on and off button, a Stereo Button and a Manual button and
also a preset button. The preset button cancels the knobs and gives
the unit it preset capibilty. The manual button turns the knobs back
on and you can make your own sounds with the 3 chorus's and the rate
knob. Also there are two huge LED meters on the front, they are
yellow. This chorus was and still is the main chorus for session
players like, Michael landau, Paul Pesco, Dann Huff, Tim Pierce etc..
and is used in countless studios and has been heard on many many
records over the years. No other chorus unit comes close.
The setup is a Left, Middle and Right LFO and the Rate control. But
there
are some knob that I think is the key. The Knob are Manual and Preset.
When you press the preset, I think it react to some of the circuit
inside
that make the unit 3 dimensional.
The Left, Middle and Right LFO really works it wonders by creating
different envelope in either side (+middle) . Also in my unit the all
the
LFO knob can be pull-out to create some kind of "enhancer" effect for
the
corresponding LFO.
Let me describe what the function of all this knob (it's a push knob):
From the far Left
- 20 Peak switch (for line and instrument switch)
Effect bypass knob
Chorus or Flanger mode (Chorus if pressed)
LFO Mode: Preset and Manual.
This is a very strange control. When the preset is engage, the effect
is
more 3-D ish.
Manual means that you can control the Rate control function. If the
manual
was not engage, the Rate will be very minimal (Subtle). The other
strange
this is that the Preset and the manual are both usually engage if you
want
a very 3-D ish and great effect.
Left, Middle and Right (min to max) Chorus Wave control. I don't think
this control function as a depth control but more of a waveform
shaper. If
you hook the system in stereo, you can actualy hear the Left side (if
only
left side being tweaked), Middle and Right.
The last one is a Rate control (Slow to fast) to control the 3 wave
control. Also noted that the 3 Wave control can be pulled (like push
pull
function in an Amp) that work sort of like BBE Maximizer (only
better !!)
for the corresponding Wave (i.e. if you pull the Left Wave form, the
only
effect will only be the left - I can actually hear the difference).
The last two row are the Output LED meter.
In the rear of the unit you have one input and 2 (L & R) output Jack
with
the choice of either Balance or Unbalance.
The last 2 footswitchable control are Bypass and Rate jack.
The Rate jack has an interesting function. When plug with a
footswitch,
this jack will control the front panel Rate control. Example, if you
set
the Rate control at 2 o'clock, when you hit the footswitch the unit
will
"creep" from very slow to your setting ( 2 O'clock) and go back again.
This function is a much debated function, even the creator (Chuck
Monte -
President and CEO of the long diminish Dyno My Piano company) that I
have
the opportunity to talk back in 1987, are puzzle on how people use the
function. Paul Pesco (Madonna, Hall and Oates & Jeniffer Lopez) and
early
days of Michael Landau likes to use this function (they even put it on
their Bradshaw loop), while Steve Lukather and Lee Ritenour did not
use it
(I've seen all of this people rack).
all 3 models of the tri sound different at certain rates too and on
some models the rate jack in the back makes the unit come alive.
------------------------------------------------------------------
(new post talking about recreating the Tri in an Eventide unit)
The front has a DB pad switch
effect on and off button
Stereo, mono button
preset button
manual button
the 3 knobs are for chorus wave form left , right and center and then
some models have an exciter function where there are push pull knobs
that really make the chorus come alive
and then there is the rate jack
its 3 chorus units in one box.
All you need is to get a chorus to wobble alot and your there for
that really landau sound from the late 80's."
This is some stuff I got from very kind folks, willing to help me in
this project.
I have builded two different versions of the "DynoMyPiano" unit:
the first one included more advanced control features, that the
original unit didn't have: the ability to store 10 different tweaks,
like presets.
The second one is the final version, that will be in the V3.0 public
release. This one is closer to the unit, without the control stuff.
The design is a group of parallel microdelays, each one being
modulated by 3 different M_UCURVE modules (Unipolar Mapping for mod
signals ) that create triangular/sine and square waves. I had to
come up with a system to progressively blend these curves, as the
original unit had this cool feature. This is one of the most
interesting sonic aspects of the Dyno unit.
The 3 chorus lines are panned respectively L-C-R.
Next cool feature to reproduce was the knobs pull-outs! Kind of an
Haas fx...so I had to add 6 more microdelays, with indipendent Lfos,
VERY slowly modulating them, w/on-off switches, named L/C/R
spreads...which really do miracles in creating different combos of
psycho-acustic panning tricks.
Next was the adding of a preset amount of feedback (as in the
original box) that could produce flanging, replicating the fx type
control (chorus OR flanging).
Tricky enough was the replica of the mono/stereo choice! With so many
delays, I had to come up with a decent sonic way to collapse
everything in mono...as the original unit allowed that!
It was basically a lot of search, testing, compare...work!
...and a terrific fun!
AND HERE'S THE MANUAL
The Dytronics CS 5 Tri Stereo Chorus / Splitter incorporates multiple waveforms utilizing variable arhythmic cycles to create hundreds of dedicated chorus effects. Multiple layering of up to six waveforms simultaneously and at random, will allow the musician/ recording engineer to duplicate any existing chorus effect imaginable as well as create new chorus colors in Full Tri Stereo.
1. Manual LFO The Manual LFO Selector permits individiual control of three distinctly different waveforms of chorus intensities 1 (left) , intensity 2 ( Center Stereo) and Intenstity 3 (Right).
2.Intensity Controls 2, 3, 4
Each of these intensity control knobs pull out to select Choral Exicter ON. All 3 exciters enhance only the high frequency of there individual chorused effect. These Choral Exciters will emulate a crisp, crystaline choral effects which are great for vocal, guitar and keyboard tracks.
3. Rate Control
One rate control variably selects the overall speed of the 3 manual intensities. A delayed response causes a gradual increase or decrease of the 3 chorus speeds- even after your fingers have left the dial- for a simulated rotating speaker effect.
4. Preset LFO
The preset LFO selector injects a side chain circuit of Tri Stereo Chorus that may be mixed simuilaneously with the manual intensities, generating up to six waveforms and speeds! This unique feature is comparable to having two units in one!
5. Chorus Mode
The Chorus mode when selected in stereo, automatically varies the phase relationship of the left and right outputs in accordance with the rate.
6. The Effect On / off will select chorus active pressing effect on. Effect intensities are actively mixed to the dry signal. Note> No mix or level controls are needed.
