Segue - NLC - VC panner/crossfader

These are my build notes for the Nonlinearcircuits Segue.

Its a very versatile unit. a VC panner, VC cross-fader, VCA and VC attenuator, process CV and audio.
Plus should be a easy build.  Though there are plenty of SMDs, they are all passive.

Andrew describes this as a "kind of hybrid between a Buchla 207 panner and a Korg PS3200 VCA".

There are just two through hole 10R resistors to instal.
Then, caps, trannies, headers.
The trim pots are all 100k.They set the gain for each channel.

I'm using Silonex NSL 32 vactrols. The white dot marks the cathode. (K on the PCB).

NLC words of wisdom: (He'll never be) an old man river.
Mmmmmmmm ????

The reference to "Ol' Man River" isn't the song from the 1927 musical of showboat.
Rather it's refering to TISM ... the Australia band.


 
 OK, its time for the pots & jacks.

 The LED works.... so does the VC fader. Very cool.

"The LED provides offset to one side of the current mirror so they turn on/off at different voltages." Andrew F advised me to "drill the panel, or just drill/scrape off the soldermask on the back and the LED will make the panel glow".

Deluge effects - filters & EQ



You can apply effects at the
1. Clip level (Kit & Synth level)
2. Song Level

Effects are available via the grid  shortcuts Or using the select knob

The Total Effects available include:
Volume, panning, HPF, LPF, Envelopes, Saturation , Decimation, Bitcrushing, Modulation (Mod FX)
EQ, Reverb, Delay, Stutter.

Synth Level
Osc type, Oscillator Volume,  HPF, LPF, Amplitude Envelopes, Saturation , Decimation, Bitcrushing, Modulation (Mod FX)
EQ, Reverb, Delay.

Kit Level
Volume, HPF, LPF, Decimation, Bitcrushing, Modulation (Mod FX)
EQ, Reverb, Delay.


Song Level
Modulation (Mod FX)
EQ, Reverb, Delay.Volume, Reverb,
HPF, LPF, Decimation, Bitcrushing,
Stutter


---------------------------------------
Filters
The deluge has 2 filters HP & LP
To access the filters:
1. Enter Clip view
2. Shift
3. Press the relevant shortcut pad
4. Turn the select knob.

There are just 6 button/effects, three for each filter
As of Version 3, the HPF slope doesn't work .. maybe a later revision ?

The short cuts work in clip mode, but don't seem to work in song mode.

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

EQ - Equalizer

 

There are 2 ways to adjust EQ
a. The short cut pads.
b. the [CUTOFF / RES] affect button & upper gold knob


Short Cut pads
Just 4 buttons for bass & Treble. (nothing for mids)

BASS
AMOUNT: 0-50. 25 is central, > 25 to boost, < 25 to cut.
FREQUENCY: 0-50 Position to boost / cut across the bass range.

Treble
AMOUNT: 0-50. 25 is central, > 25 to boost, < 25 to cut.
FREQUENCY: 0-50 Position to boost / cut across the treble range.

To access the Eq:
1. Enter Clip view
2. Shift
3. Press the relevant shortcut pad
4. Turn the select knob.

The short cuts work in clip mode, but don't seem to work in song mode.

 [CUTOFF / RES] affect button & upper gold knob

1. Enter Clip view
2. Press [CUTOFF / RES] affect button
3. Press UPPER gold knob to cycle between LPF, HPF & EQ
4. select EQ by releasing the control.
5. Turn (UPPER) to change TREBLE band amount or turn (LOWER) to
    change BASS band amount for the sound selected.

Note:
You can effect individual notes or the whole kit
Press [AFFECT ENTIRE] to affect the entire kit.
Turn (UPPER) to change TREBLE band amount or turn (LOWER) to
change BASS band amount for the entire kit selected.

NonLinearCircuits - Dual Drums Build notes.

These are my build notes for the NLC Double drum module.
Andrew did include the Dual Drum in one of his 4U drum panels


I plan to put this in with my Buchla. I don't have a face plate so will make that too.
From Andrew's notes:
"The core design was originally (used) in a Japanese DIY
magazine from the late 70s and was intended as a standalone, self
—contained device to be used with a drum kit. 

The cool thing about this module is that it uses an envelope detector
so most input signals should trigger this.

 firstly the virgin PCB.




I usually solder the SMDs first ... to both sides of the PCB.




The 22n SMD should be a 22k resistor?



BC547 --- NPN transistor - four needed --- the unlabeled trannies on PCB
BC557 --- PNP transistor - just two needed.... marked as pnp on the pcb.
Diodes - I'm using 1N414s



The unmarked caps are for the decoupling caps - using 47nf ceramics.

Time to make the panel. It's something a bit out of the square, ..... a half size Buchla panel.


The rear of the panel.



The 1k LED resistors seen to work fine.


First tests:

Essaouira - Morocco

Some pics from Morocco 2004



Essaouira is  on Morocco’s Atlantic coast. 





Its medina (old town) is protected by 18th-century seafront ramparts called the Skala de la Kasbah, which were designed by European engineers. 






Old brass cannons line the walls, and there are ocean views. There are strong "Alizée" trade wind.
Great for wind surfing



Very laid back place.
