Deluge Scales & velocity (Clip/track view)

Scales

Obviously, go to Synth mode.
To changes scales :
Shift + Scale button.

The Deluge will cycle through the 7 Western-music scales: major (ionian), minor (aeolian), dorian, phrygian, lydian, mixolydian, and locrian.
Scales on the Deluge will usually contain seven different notes.
(sometimes there will be more notes - for instance, if both a major 3rd and a minor 3rd are present when entering scale mode, both will be added to the scale.)

The deluge is quite clever as it can detect if a note you entered is in the correct scale.
If not , it will try to guess where that note will be 

The root note (at every octave) is indicated, anytime that a clip is in scale mode, with its audition pad permanently illuminated.

Any change that you make to the scale while editing one clip will affect all others that are also in scale mode

If you wish to transpose a clip up or down, this can be achieved by holding down the ▼▲ knob and turning it. Doing this alone will transpose a whole octave at a time. If you wish to transpose just a semitone, then hold down the shift button as well while turning.

To sharpen or flatten a note
1. Hold the audition button.
2. Turn the select knob.

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

Note Velocity
This effects both synth & kits

The Deluge’s pads are not velocity-sensitive but you can still edit the velocity.
Changing velocity has the effect  of changing volume.
1. hold down the pad corresponding to a note.
2. turn the ◄► encoder. (Velocity values range between 1 and 127.)



1050 Mixer sequencer - Build notes

This is a Eurorack module inspired by the ARP 2500 mix sequencer.

There are lots of SMD components so it's probably not a good one for beginners.


Here are Andrew's build notes:

Some pics of the virgin PCB & Panel

Some NLC words of wisdom

This is great SMD soldering practice.
I like to get those ICs on first. These are SOIC.
The sequencer section uses one CD 4017 (decade counter) , three CD4071s (quad 2-input OR gate) and  one CD 4081 (CMOS Quad 2-input AND gate).


The 4017 decade counter is central to this sequencer.
Sending a pulse to the clock input (pin 14) sends a pulse out from each of the outputs in sequence.

A bit about gates.

CD4071 (quad 2-input OR gate)
 
 Truth table of the OR gate:

 CD 4081 (CMOS Quad 2-input AND gate).
This is the truth table for the AND gate
I'm using a DG 212.
Here are the mouser details.

You can also use a DG 442. Just make sure it can handle +/-12V.
My DG 212 can handle +/-15V so should be OK.
It's an analogue switch. 4x SPST.

Some earlier versions of the DG442 require a voltage offset on pin12, the spaces for these resistors are on the PCB marked 100k* and 120k*.
New versions do not require these resistors, so check the datasheet for your  IC, if pin 12 is marked ‘NC’ you do not have to install these resistors.

My DG 212 has pin 12 marked as VL. so I will install the resistors.
Data sheet.

Next install the rest of the SMDs.... lots of resistors & caps. These are 0805s
Parts marked "c" are 100K .

Then the through hole stuff.


Install jacks, switches first. Line up with panel.
Then pots. I used B100K.

Don't forget the ground wires for the jacks. I use left overs from caps & resistors.

The PCB looks like this:

Finally the LEDs

LED orientation : The long lead (anode) , (+) goes into the square hole on PCB.


Yah it works. Nice one Andrew.

Korg PS 3100 - Envelope Modifiers (EM)

These EMs establish the changes in volume that occur over time when a key is pressed.
It's basically a VCA with an attached envelope generator.

Looks simple enough. .... An attack, a Decay & sustain knob.

In addition to controlling the VCA, it also can be used to control the filters.... specifically their cut off frequency. This effect is controlled by the EXPAND knob in the filter section.

The RELEASE is interesting ... it's a switch with 3 settings:
Damped, half damped & release.



 Re the KBD HOLD switch:
When the switch is ON, all EM controls (with the exception of Attack) are disconnected.
To experiment with this feature:
1. Turn the attack knob to the range of 7 to10.
2. Turn on the HOLD switch
3. Press a number of keys , one after another leaving a small space of time between each.
     Wait ... about 5 secs if the attack knob is at 10... sound will suddenly appear.... in the order you played the keys . Set the attack knob to 7 if you wish to hear the sounds sooner.

To release the HOLD, turn attack to 3 or below & turn the hold switch to off.

Korg PS 3100 - Resonator

The resonator section is made up of 3 filters.
The top knob  adjusts the degree to which the resonator will effect the sound.


They may be set to resonate at a peak anywhere between 100Hz to 10KHz
The 3 resonator knobs will determine the frequency of the resonator peaks.


These filters are great for effecting the timbre.

The switch turns on or off modulation from MG2
The knob limits modulation from external CV which may be patched in via the patch panel to the right.

Switches - Toggle mainly

All about switches

MTS stands for Minature Toggle switch.
The Switch bushing  has a 6mm diameter.

There are a few variations on these switches.
1. Momentary switch remains in its “on” state only as long as it is being compressed. Once the user removes the compression of the switch the device is no longer on. ...
2. Latching switch needs to be pressed once for ON and again for OFF, for example a light switch.
3. Non-Latching - When pressed it is on. The reverse action is off 

There are also various codes:

MTS 101 On - Off. SPST

Korg PS 3100 - Modulation Generator 1 & 2

Basically these are LFOs

You have a choice of 4 wave forms  plus white & pink noise.

You can send the MG1 to the LPF & SG
Most synths have LFOs with frequencies between 0.1Hz & 10Hz.
MG1 however has a range between 0.1Hz to 1KHz.
----------------------------------

MG 2 --- another LFO
Just 1 waveform  - saw.
You can only adjust the frequency.

It is routed to the resonator by default.

You can also use the patchbay.

Arranger View - deluge

This allows you to put all your clips together in one place to build a complete song..
It's pretty much like a DAW  ..... such as the Arranger View in Abelton Live.
(Song view is like Session View in Abelton, and clip/track view  is akin to playing individual clips in Abelton) .
And just like in abelton, the Arranger, Song & clip views are not independent of one another.
Song view is made up of clips, and Arranger view is made up of tracks ... kinda like in Abelton
The nice thing about this view is that the song loops CAN BE  arranged independently from one another ..
It's not linear .....
that is they can overlap...... clips can start and end at separate times.

To enter arranger view:
1. enter song view. (solid blue LED)
2. Press the song view button again.
    The Blue LED should be flashing and you are now in arranger view.
     (The main Grid is blank. The mute / launch pads will be lit.).
3. You can place an instance of a clip onto a track’s row by pressing a pad.
     if you tap a pad on the clip-instance other than its leftmost pad, you'll be taken into
     clip view for that clip.
    Clips are arranged according to the section colours (there are 12 colours in total)
    ie: the colours of clips in arranger view reflect the colours for the respective
    section in song view.
 4. There is  just one row per instrument, MIDI, CV, audio.
      eg: a synth in one row. A drum in another row , Cv  & midi in another, etc etc
     Holding down on audition pad will reveal the name of that preset in the display.
     Each instrument can be muted and unmuted as in song view.
4a.  To Change or add a new Instrument for a row
        Hold Audition pad + turn select knob or press instrument-type buttons
5. If you press any song instance tail pad ie a pad to the right of the first brightly lit one),
    you can see the original clip.
6. You can change the CLIP INSTANCE of an instrument by holding the PAD and
     turning the Select knob.
7. The Undo / redo button works in arranger view.
8. Press SHIFT + SCROLL<> to move clips left or right.
8a. To Move a clip-instance horizontally
      Hold grid pad of clip-instance and scroll horizontally

9. Press PLAY to play the song of Arranger view.
10. Press PLAY to stop



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

White Clips

White Clips are unique.  they are independent from the original.
You can create two types of white clip.
1. A brand new white clip in the row that is totally blank.
(That is, it doesn't contain any note or sound pattern information).
 OR
2. A white clip that has a variation in the original pattern.

1. To create a Blank White Clip.
a. hold a PAD and turn the Select knob (turn anticlockwise) till the pad turns white.
   You may also convert an existing coloured clip to a white clip by pressing :
          [SHIFT] + [PAD head]
b. Pressing the clip ‘tail’will switch to clip view where you can see that no
    notes or sound patterns exist.

2. Creating a White Clip with the old pattern.
    You are converting an existing clip to a white clip    
    This allows you to make a variation of the old pattern which won't effect
     the original source clip.
    a. Press [SHIFT] + [PAD head] of an existing coloured clip
        The head of the clip will go white.
    b. Press the 'tail' of the white clip to switch to clip view.
        The clip will still contain the old note info.
    d.  make your variations to the pattern.
    e. Press [song] to return to arranger view

 ---------------------------------------------------------------------------------------------
Recording your Song into Arranger view
Another way to use the arranger view is to play the clips in Song view and record that
performance into arranger view.
This is just like in Abelton.

1.Set up song view as usual (mute what is necessary)
   Solid blue LED.
2. Press & hold the Record button
3. Press the Song button again
    You will now see a flashing blue LED but will stay in song view.
    The Play button will automatically light green.
4. Do your performance.
5. When finished, press PLAY.
     The flashing blue song button will now be solid.
6. Press song to enter arranger view.

--------------------------------------
Entering a clip from song view into Arranger view (and vice versa)
1. enter song view
2. Press a pad on that clip
3. Press song button
4. The clip will be copied into arranger view

You can do the reverse of this if you are in Arranger view, and wish to
drag a clip into song view. This is useful if you have made a white clip in arranger view.
You can drop it into song view. Once you have done this, the white clip will be assigned a new section colour, which will also be visible the next time you go back into arranger view.,,,

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

Deleting tracks in Arranger view ****
1. Hold down the audition button
2. Press save/delete

*** this feature doesn't seem to work
        Future update ??

Clearing the entire existing Arrangement.
Hold [SCROLL▼▲] + [BACK / UNDO]

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

Playing in Arranger View

To start from the beginning, 
 1. press PLAY

To play from a  desired/current scroll position. 
1. Scroll to the position
2.  Press & hold (left/right SCROLL◄►)
     (don't turn the knob)
3. Press [PLAY]

To solo a track.
 1. Hold down the Left/right SCROLL◄►knob
 2. press the Launch/mute pad (turns blue)
 3. to Unsolo -  press the mute pad again.

To move an instrument
1. Hold down the audition pad
  2. turn the up/down knob

Changing a Tracks Preset / instrument
1. Hold down the Audition Button.
2. Turn the select knob
     or
    Press the track type button (Synth, Kit, MIDI, CV)

Note:
You can jump from arranger view to song view (and back again)
while the song is playing in arranger view.
This won't effect or interrupt the performance.
----------------------------------------------------------------
Rename tracks
1. Press Audition tab
2. Press name tab
3. Press eNTER (on qwerty keyboard to confirm & save)


----------------------
To clear the entire arranger view.
1. Hold down the left/right knob
2. Press Back/undo

-----------------------------------------------
Automation

Press shift + these header buttons (for the clips)
They are now stand alone clips and you can add your automation to them without it effecting
all the other clips in that row.

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

Inserting & deleting time
1. Hold shift and turn the ◄► knob
    This will move all clip-instances which are currently on-screen or to the right of the current screen.

2. Any clip-instances which “fall off” the left of the screen are deleted -
    but you can get these back using the undo function (press back).

Korg PS 3200 - 15. Keyboard PS 3010

The Keyboard is quite useful.
Though I can control the 3200 with a Midi keyboard, The 3010 has lots of extras such as a joystick,
a slide switch, and a momentary switch (M.SW).


It connects to the PS 3200 via the chunky cable.

Korg PS 3200 - 13. Adding Amp

The adding amp is much like a mixer.
It has two inputs for the signals to be mixed.
The inputs can be anything ... even DC, though they should be in the -5V to +5V range.
You can use it to add & mix things like the MG-1 & GEG for example.

There are 2 outputs: Normal & inverse.
Inverse provides an output where the signal is of an inverted phase polarity.
Notice the outs have a range of -10V to +10V.
In addition to mixing, it can also multiply or amplify the output voltages.
So it's probably a good idea to be careful when patching out from this module into the
rest of the system.

EMS Synthi - 1. Playing the keyboard

If you have never used a synthi AKS, you may wonder why the keyboard doesn't just work straight out of the box.
This is a basic patch to use the KS as a simple keyboard.


So there are 3 required pins: D3, A12, I8.




An extra pin can be put in at O9 for loudness control
OR
L9 for decay
