ARP 2500 - 1046 envelope generator & eloquencer

Some notes on the ARP 1046 envelope generator.

Triggering the ARP's envelopes is a bit tricky if you are using eurorack, as most modules put out only 5V gates & triggers. This is usually not enough.

...

I've just ordered FuzzBass TTSH gate booster PCB but while I'm waiting for it to arrive

I decided to test the Eloquencer sequencer by Winter Modular with a ARP 2500

 

The Eloquencer sends out 8V gates - good enough to trigger the 1046 EGs
You need to adjust the gate length from the Eloquencer.

Most of the old ARP gear seems to want +10V but will usually act on +8v.

yOU CAN trigger the EG from either the upper matrix or lower matrix

The upper matrix allows you to treat the 1046 as if it is 4 "basic" EGs

Use the lower matrix if you want to use the 1046 as two "combined" EGs
When the Trigger Mode switch is in the Multiple setting you need both gates & triggers to activate an envelope. In the single mode, only a gate is required (T not needed).

If you apply another trigger signal while the gate is still present the cycle
will restart. ..a good way for creating multi-peak envelopes.

The 1046 QUAD Exponential Envelope Generator is actually a ARP 1003 & 1033 in a single module.

The 1003 has the stages: Attack, Initial Decay, Sustain, Final Decay

The 1033 has the stages: Gate Delay, Attack, Initial Decay, Sustain, Final Decay

 The main difference between the two is the addition of a gate delay

As a side note, the ARP 2600's envelopes also can't be triggered with most eurorack gate/trigger modules. The ARP 2600 uses a gate range of 0-10v

The Gate & trigger output of the ARP 2600 keyboard is +10V

The FuzzBass TTSH gate booster is a useful module to have. In addition to the need for a 10V gate, the 2600's ADSR circuit has a retrigger function.

This requires a 10V trigger signal. This allows you to reset/restart the cycle when you press a second key (without disabling the gate signal).

I can also clock the eloquencer (slave) from the ARP 1027 sequencer's clock (master).
The 1027 clock sends triggers not gates.

The Greyscale Algorhythm also triggers the 1046 envelopes.

Use the gate inputs of the 1046

+ More about the 2500's EGs

Eurorack modules that might work (I haven't tested this) with a 2500 or 2600 are:

+ MI Marbles - Output levels: -5V to +5V for CVs (largest setting), 0V to +8V for gates.

+ Make Noise -- maths, Rene & pressure points, 0-coast/0-control

+ ER - 101 - 9V

+ Doepfer A-149-2 .... +12V gates

+ TTSH gate booster (fuzzbass) .. converts voltages over 3V to about 10V 

+ The Arturia Keystep is also very useful.

    CV/GATE outputs: CV supports 1Volt per octave, Volt>Hz modes, 

    Gate output 5V or 12V for modern or vintage gear support

+ Arturia beatstep 

    CV/GATE outputs (1 volt per octave CV, 10 volt gates)

+ Arturia Microfreak

   Gate signals can also have different output ranges (S-Trig, V-Trig 5V, V-Trig 10V).

   CV: 1 Volt/octave (0-10V), Hertz per Volt, 1.2 Volt/octave (a Buchla specific standard)

Eloquencer - Copy A Track To Another Track In A Different Pattern

 Copy A Track To Another Track In A Different Pattern

We are in edit mode (CV, GATE, GATE LEN, RATCHET) and we have chosen the track we want to copy.

1. Copy (press Function + Copy and hold) 

    The OLED will display "Trak Copy"

2. (While holding) deselect the parameters you don’t want to copy by pressing the relevant green lit edit mode buttons 

3. Release Function + Copy 

4. Go to Pattern Mode (hold Function + Pattern for at least ½ second) 

5. Choose the desired Bank and Pattern (via the Track then Step buttons) 

6. Go to any of the editing modes (CV, Gate, Gate Length, Ratcheting) 

7. Select the desired track you want to paste the track to 

8. Paste (Function + Paste for at least ½)

Eloquencer - creating parts.

 In the Eloquencer, you create parts by joining patterns.

You join Parts to make songs.

The manual says that a song can have a potential max of 256 linked parts.

(Some of these parts would be repeated as you can only save 64 unique parts into

the memory of each project).

To make Parts

1. Go to Song Mode

     Function & Song (Long Press).

You will see displayed this on the OLED

2. Scroll down to Create Parts.

3. press the encoder

4. We have 4 banks of 16 patterns to choose from.

     You will see this on the OLED

      A1 is your first Part.

      You can create 4 banks of 16 parts -- 64 parts

      The parts are labelled 

      A1 - A16, B1 to B16, C1-c16, D1-D16.

5. Part length

    This changes every time you add a pattern.

     

6. Press Start

    You will see the patterns that are available displayed

     as lit step buttons

      A1 - A16, B1 to B16, C1-c16, D1-D16.

     You can select any of the 4 banks

7. Add your patterns by pressing the step buttons.

    You will see the part length go up each time.

8. When you are done press Finish.

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

To play a part return to SONG Mode.

If you wish to return to PATTERN mode to edit patterns, you must turn OFF song mode.

You do this while in Song Mode

    

Eloquencer - master track length

 This can be accessed by pressing Function & the clock button.

 

The Master track length changes the reset point of the pattern when master track is set to INT'.

 

The default is 16

 

 

It has a  max of 64 steps. 

This is not to be confused with making longer sequences.

 

 If I want to extend the length of my sequences to 32 I just need to chain two 16-step patterns. 

If I want to make a 64 step sequence, just chain four 16 step patterns

 

 To explain better what the Master Track Length really is I'll quote something I read in

 the WM forum

"Let's say I chain A1 and A2, MT is INT, and MTL is 16. When I press play the Eloq would play 16 steps in A1 and then will reset, so it will jump to the next pattern (A2). It would play 16 steps in A2 and will to jump to A1 again.  A1-A2 > A1-A2

If I set the configuration where MTL is 32, Eloq will play 32 steps in A1 and 32 steps in A2, so that would be like playing A1-A1-A2-A2 > A1-A1-A2-A2"

(Winter modular forum) 

 So in other words, making the master length to 32 will make the pattern repeat.

Eloquencer Sequencer - Notes - SONG structure

This are some personal notes for getting aquainted with your new Eloquencer sequencer.

The structure

The eloquencer's method of storing patterns and creating songs seems a bit confusing at first glance.

The thing to remember is that the "project" is at the top level of the system structure.

You can create up to 128 projects.

I like to view each project as something special I create for a particular gig.

Every Project is made up of songs.

Songs are made up of parts

Parts are made up of patterns.

Every pattern is made up of a max of 16 steps.

I think the best way to work with the Eloquencer is to start  at the most

basic level and make PATTERNS.

Then chain the patterns to make PARTs.

Then chain the PARTS to make SONGS.

Once you have enough songs for your gig, store then into a project.

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

Each project contains 4 banks of 64 patterns.

Thus one project can have 64 x 4 = 256 patterns.

Each bank can be accessed while in Pattern mode by pressing the first 4 Track buttons.

A,B,C,D.

Then press one of the the 16 step buttons
 

A pattern is made up of 8 tracks.

How these  patterns are grouped and chained is how you make a song for live performance..

and each of these songs are stored with other songs within a project.

These patterns can be joined or chained to make "PARTS".

(The parts have a max number of 16 patterns

These patterns can be any of the 64 patterns that are stored within that project).

You can join these "Parts" to make a "Song".

 A Song is a sequence of Parts with a maximum length of 256 Parts

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

So when you begin, you can assess your patterns, in Pattern mode.

You go to Pattern Mode by

1. Holding down Function & long press the Pattern button.

2. you navigate between the 4 banks of 16  with the top 4 track buttons

and the 16 step buttons.

3. add your new pattern by pressing an unlit step button then

    entering your notes.

4. save.

 

 

 

Saving is done in Project Mode

 

 

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

 

This is song Mode;

Its here where you create PARTS and SONGs

 

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

The CV, GATE , G Length, Ratchet buttons have multiple function.

 

 

 

They change colour if pressed repeately... to indicate probablilty etc etc
