Roland -SE 02 - clocking with an external trigger

 The SE-02 has a TRIGGER IN and TRIGGER OUT jack on the back of the synthesizer. 
 
This is a great way to sync and clock the se02 with old fashioned analog triggers, gates, etc.
You can of course just use MIDI, but where's the fun in that?
 
The manual is a bit cryptic so here is a brief and hopefully simplier rundown.
 
For this to work you need to set the SEQUENCER clock source to trigger or“trg" (tr9).
 
First, set the MODE switch in the common section to SEQ mode.
The MODE SELECT SWITCH is where you can switch between PATCH, SEQUENCE or SONG mode.
In SEQUENCE mode, use the buttons to choose the type of data you wish to sequence - Note, Gate, Glide, clock, etc
 
IN this case we want the sequencer to advance every time it receives a trigger.
 
1. Set the MODE switch to SEQ.
2. Press the NOTE button and GATE button to make them light 
3. Use the [1] - [3] buttons to select a parameter, and use the VALUE knob to edit the parameter’s value. 
    The display indicates the value . In this case press button [2].
    Button 2 sets the clock sync.
    The choices are: Int: Internal
                              N id: MIDI IN 
                              USb: USB MIDI
                              tr9: Trigger In
4. To save this setting perform the Song Write operation.  
    This setting is saved with a selected sound patch.
 
A. Press the VALUE knob. You will see the current song's blinking LEDs
B. Use the [0] - [16] buttons to select a new destination.
C. Press the VALUE knob. You will see a confirmation message appear on the display.
D. Press the VALUE knob to save.
 
 5. Connect the GATE or TRIGGER output of your external sequencer to the TRIGGER IN 
      jack on the SE-02

Roland SE 02 - Initialize & Fat Bass Patch

This initialise patch is good for most Moog like synths without presets.
Works for the Mini-Moog Model D too.

I'm using a SE-02 (my preset 101)



It's a basic single oscillator saw tooth patch.
 Sounds like this:


AND



Starting from left to right.

Glide = 0

Osc 1
Range  = 16'
Tune = 0
Waveform = saw (ramp up)

Osc 2
Range  = 16'
Tune = 0
Waveform = saw

Osc 3
Range  = 16'
Tune = 0
Waveform = saw

XMod = all zero

Mixer for Osc 1 = 10
Mixer for Osc 2 = 0
Mixer for Osc 3 = 0

Feedback & noise = 0
Filter
Cutoff = 2 - 4 (open)
Emphasis = 0
Contour = 0
attack =0, decay = 0, sustain = 10

Amp
attack =0, decay = 0, sustain = 10

 --------------------------------------------------------------------------------------------------------
Moog synths are famous for their "fattness".
It's hard to put a finger on it.
I think its all about the Ladder Filter & the Oscillators.... not individually,
but in combination. (and it's not just 2 detuned oscillators).
Other synths have these too, but there is something special about a Moog synth.
The SE 02, though not from Moog, sounds pretty darn close.

 To make a fat Bass sound (My preset 102):


Glide = 0

Osc 1
Range  = 32'
Tune = 0
Waveform = saw (ramp up)

Osc 2
Range  = 32'
Tune = 0
Waveform = saw

Osc 3
Range  = 32'
Tune = 0
Waveform = Pulse (25%)

XMod = all zero

Mixer for Osc 1 = 10
Mixer for Osc 2 = 8
Mixer for Osc 3 = 3 - 9 ( I like 5)


Feedback = add just a little (3)
                   Raise the main volume up to make the feedback more prominent.
noise = 1 to 2 (just add a little noise)

Filter
Cutoff = 0 - 3 (open)
Emphasis = 0 - 3
Contour =  5
                (increase if you want more "snap" in the attack)
attack = 0 to 10ms , decay = 0 to 250 ms , sustain = 5 - 10

Amp
attack =0, decay = 600ms , sustain =8

 Sounds like this:

Roland / Studio Electronics SE - 02 envelope

I'm revisiting my SE -02 synth .
The Studio Electronics / Roland Boutique synth has a rather unusual envelope, which is kinda borrowed from the Moog Mini D.
It's not a clone of the Moog, though I thought it would be useful to compare the two.

The most common type of envelope is the ADSR.

It has 4 stages. The stages are:
Attack : is the time taken from nil to peak, beginning when the key is pressed.
Decay : is the time taken from peak to the sustain level.
Sustain : is the level during the main sequence of the sound's duration
Release : is the time taken from the sustain level to zero after the key is released

The Mini Moog D was unusual in that there were just 3 knobs to control a 4 stage envelope.
Most synths have 4 knobs.
Attack, Decay & Release are all time based.
Sustain is a voltage level. It is usually "flat" and does not change during it's phase.

Usually the envelope starts with a signal from a keyboard or other source. It goes through the attack & release stages. When it reaches the sustain phase, it pauses and remains there until the gate goes low (e.g., from the keyboard key being released).



There were two identical envelopes ...  one for the filter, and one for the amplifier

The decay knob doubles as the release knob.
So the envelope can be seen as a ADSD envelope.

It's interesting though not surprising that Studio Electronics decided to use a similar envelope configuration.
My SE-MidiMoog (which is a rack mounted Model D) started this all off.



The SE-01 & SE-1X saw the return of that release knob, but the SE02 saw it's demise once again.
 SE-01

Maybe the decision to drop this pot, was based on practical considerations like the lack of space on the Roland Boutique synths.

SE-02

So looking at the front panel of the SE 02 one can see we have 2 envelopes:
A Filter and a Amp envelope.
Neither envelope has a release knob. They both however share a release switch
which is in the the lower right corner.
It's settings are: 2, 1&2, OFF
2 = The release stage is applied to the Amp
1&2 = The release stage is applied to both the filter & AMP
OFF = No release stage

Remember that the decay value = release value.

----------------
About the other knobs & switches in the Filter/Envelope section:

Key Track
1/3  = The filter frequency changes by 1/3 of the pitch change.
2/3  = The filter cutoff frequency changes by 2/3 of the pitch change.
          If both switches are on, the filter cutoff frequency changes by the same amount as
          the change in keyboard pitch.

Contour
Adjusts the amount the filter envelope effects the filter frequency.

Normal / Invert switch
Specifies the polarity of the filter envelope that is controlled by the [CONTOUR] knob. If this is set to “INVERT,” the polarity is inverted.

Mtrig switch
If this is on, the filter envelope restarts each time you press a key.

LFO/GATE
Specifies the signal that controls the amp envelope.
LFO: The LFO controls the amp envelope.
GATE: The Note or Gate controls the amp envelope
