Fenix II & III

Some tweaking of the old Fenixes 
II & III this time.
 
The Fenix III is a sequencer

Comparing the sounds of the filters.
 

This one uses filter 1.
Its a state variable filter with CV controllable inputs
for cutoff frequency and resonance

Synton Fenix III - sequencer companion notes - 2

 This is part 2 of my companion notes for the fenix III sequencer.
 
 
Part 1 is here:

Note that the patch points are colour coded.
+ Inputs = Black
+ CV out = blue
+ Bus in/out = yellow
+ CV step input = grey
 
+ It is NOT OK to interconnect the blue outputs
+ It is OK to interconnect black inputs
+ It is OK to interconnect any number of yellow outputs
       These yellow outputs are binary (gates ... >7V or <1V)
       If one or more of the interconnected yellow sockets is HIGH, then all will be HIGH.
------------------------------------------------------------------------
Buffer Modules.
This module operates only for Logic signals ... eg those from the Yellow Bus outputs .
A Buffer is a special Logic gate. It's a non-inverting amplifier.
 
It is recommended to use a buffer module when connecting the yellow Bus to a normal gate source or an input (such as the clock input) which has internal patching.

A buffer will turn a non-buffered output (yellow jacks) into a buffered output.
When in doubt it doesn't hurt to use a buffer. Its a safety module.


--------------------------------------------------------

----------------------------
 
The Master clock module controls the speed of the sequencer
 
The Clock frequency can be set by the frequency knob
and modulated with an external voltage at the FM1 and
FM2 input or by external Midi
 
There are 5 clock outputs:
Clk out, 
Out x 4
Out/4
Out/16
Out/32
 
 
The Clock outputs are I understand to be same voltage range as Gates .. that is ... 0 to +8V
 (need to confirm with a multimeter) 

If you want to connect the Fénix with an instrument based on S-Trigger (Vintage Moog 
or Korg MS 20 etc), you need an S-Trigger converter. 
If you want to use an S-trigger to control the Fénix, you can connect the S-trigger to
 the (-) input of the comparator and the output of comparator
can be used as gate. You'll have to look for a correct setting with the control knob.

The CV out is the CV of the Frequency knob. 
You can use this as an additional control voltage. 

The R/S and Reset inputs need Gates to work.
Anything larger than +5V is high
Anything under +1V is low
 ------------------------------------------------------
 
The 3 main sequencers (C1/B1/A1) have some unique input controls:
 
To clock the sequencers using an external sequencer you'll need
a +5 gate (or larger).
A signal larger than 5 volts is considered
high, and a signal that lower than one volt, low. 
The gate and trigger outputs produce such a signal.

Synton Fenix III - sequencer companion notes - 1

 Some personal notes to help with the official manual

The Fenix III is a wonderful sequencer. 
One of the most flexible Ive every had the good pleasure to own.
It is totally modular.
 
You can view it as three main CV/Gate sequencers
with a 4th expander sequencer
The sequencers are a bit confusing at first.
I'll divide them into CV & Gate parts, then see how they work together.
 

The CV sequencers

From top the CV sequencers are labeled: C1, B1, A1 (blue knobs)
The 4th (expander) sequencer, named A2, has red knobs.
The sequencers produce CV voltages between 0 & 8 volt.
These are the CV outputs of the sequencers:


They can be clocked via the master clock, external MIDI or external CV.
By default, the master clock is connected to all 4, but can be overridden 
with a signal at the clock input or CV-step input

Sequencers B1, C1 and A1 are pretty standard 16 step.
Forward, ping-pong, random modes.
A2 is an expander of A1
The A1 expander can be 16 steps, 2 x 8 steps, or in Inverse Mute mode.
 

The Gate sequencers

 

There are 4 of these: C4, B3, A4 & A3
It is important to understand the difference between gate and clock signals
A gate is a continuous high signal.
A clock has a high & low state for every step.
The clock can be standard (50% high / 50% low) or variable (called a PW clock) .
The PW (pulse width) clock can be changed ... eg (10% high/90%low or 30% high / 70% low , etc  etc).
We can even apply a CV to modulate this pulse width.
 --------------------------------------
C4-C1
The C4 Gate sequencer is linked to the C1 CV sequencer
 

 The C4 gate sequencer uses 3 position toggle switches (as do all the other gate sequencers).
In the manual, C4 is called Gate expander 1 (page 17).
The extreme left toggle with the yellow cap switches between Gate/clk/PWM.clock.
 
The PWM clock is always the master clock and not any external clock.
Thus the Clk setting can be any external CV used to clock this sequencer
(such as an LFO)
or the master clock if that is what is timing this sequencer.

The 16 toggles (above the rotary encoders) select between Yellow switch/off/clock patterns.
Up = Yellow switch pattern; Middle = off; bottom = clock pattern.

This means that if the switch is in the bottom position, the output will have a clock signal,
and if it is in the top position, it will have whatever the yellow toggle is displaying.
...........................................................................
 B3-B1
The B3 Gate sequencer is linked to the B1 CV sequencer.
 
Slight difference to c4-c1.
In the manual, it's called Gate expander 2 (page 18). 
This gate expander has 2 outputs (row 1 & 2) and runs in sync with the CV sequencer B1 .
 
The extreme left toggle with the yellow cap switches between Clock/skip/PWM.clock.
The extreme right toggle switches between rows 1 & rows 2
The 16 toggles (above the rotary encoders) select between Row 1/ off / row 2.
 Up = row 1 pattern; Middle = off; bottom = row 2 pattern.
 
 
 -----------------------------------------------------------------------
The A3 & A4 gate sequencers
 

The A3 gate sequencer has two rows of outputs -- row 1 (top), row 2 (bottom).
You select which row using each of the 16 switches above the pots.

The A3 gate sequencer exits from Gate output A.
Its outputs are PW/ Row 1/ Row 2
It is identical in function to the B3 gate sequencer

The A4 sequencer outputs via "Gate C4".
(I wonder if this was a mistake in the panel design ???
was it supposed to be A4??)
Its outputs are PW/Mute/Out/Trigger
It functions much like Gate sequencer C4



I'll add to this page over time.
please let me know if there are any mistakes.

Fenix IV - Synton - TINRS

I met Stijn and Priscilla Haring-Kuipers of TINRS (This Is Not Rocket Science) yesterday and was excited to learn that there is a new Fenix in the works.



Looks like this is their new prototype sequencer
I love my Fenixes. I wonder what the new synth will be like.


The old sequencer was awesome ... still one of my fav seqs of all time




Some links to follow:

Fenix I & III (and a Roland CR 78)


video:






The Fenix III sequencer has a very useful clock divider (left of photo). The Roland CR 78 needs a 48 pulse per measure clock to sync. The Fenix clock divider needed a bit of tweaking but worked.

Here is the unedited video:

Fenix 1 & 3 - sequence two


Synton Fenix 1 & 3.
All sounds are from the Fenix 1.
The F3 is purely a sequencer (on steroids).

Synton Fenix 1 - VCOs, EGs & VCAs

I though I'd upload some pics & a brief description of the VCOs, envelope
generators & VCAs of the Synton Fenix 1.

First the oscillators:


There are three VCOs. The first is the most complex with no fewer than 7 CV ins.
CV 1 is fixed to 1v/oct. We also have a CV2, PWM , sync source  & sync level input.
There is also a CV in for FM, and a CV to control the phase of the sub-oscillators.
The sub oscillators are both square an octave & 2 octs down..... great for some deep bass.




 There are 5 audio outs. - sine, square, ramp (reverse) and I've mentioned the square subs already.
The bottom dial is a phase shifter. - allows you to un-sync the phase of the sub-oscillators for added vibrato or to thicken up the sounds if mixed with other waveforms.

VCOs 2 & 3 are simplier. They have square and sawtooth waveforms with individual outs & four CV inputs
------------------------------------------

The VCAs are pretty standard:
Each have an audio  & CV input, and one out.


 The envelope generators are very different to your standard fare. EG 1 is described as a APDSR.



What's the P stand for?
P = Peak Hold.... this is a time control where the envelope is held between the attack and decay phases. (In EG2 the Peak Time is only active if the decay-release switch is set to the decay position)
In EG1 & EG2 the top pot sets the length of Peak Time.


From what I can decipher, EG1 can actually be used as TWO separate envelopes:
Top: A(P)DR.
Bottom:  a simple AD

EG 2 is like nothing I have seen before.
Firstly it has three outputs & there is no sustain control.
It has a switch which allows you to select between a APD envelope or APR envelope. We have pots for the attack time and peak hold time, plus a knob and a CV input for the Decay/Release time.

So it looks like the EG2 can be broken up into 3 separate envelopes:
EG2(a) = 1 which is the APR or APD (depends on the switch setting)
EG2(b) = 1 + 2 {a combination of EG2(a) + EG2(c)}
EG2(c) = 2 which is a APD envelope.

Goodness gracious me !!! :-)

EG3 is also very unusual.
Again, there are 3 outputs.
The upper one is your envelope.
The lower two are outs for gates (positive & Neg).

The envelope itself  has only decay & delay settings.
It behaves like a simple AD envelope with a sharp attack (immediate)

The Delay knob is a time delay. It delays the start of the envelope.
The delay will also delay the gate outputs relative to the gate inputs.
