Finally getting a easel system together which combines the 208 with 200e.
I've had this beautiful 10U case (by Jason Butcher) for a few years now.
Was in a quandary as to which modules to put in. Should it be all 200/ 200& 100 combo
or 200e?
As the case is a variation of the classic Music Easel case from the 1970s (Halliburton)
a 208 is obilgatory.
I've decided to go with 200e for now.
It's good to have something different to the standard easel configs.
Seems like a good combo.

LCD Displays - Arduino
Here is a basic LCD project.
A LCD is a Liquid Crystal Display.
It uses a 16x2 LCD display.
The exercise uses an Arduino.
Some of the older LCDs that Ive tinkered around with have a different pin out, but the basic ideas are the same.
I'm doing this project as it's good way to learn a bit about this older but proven technology.
LCD displays are often used in DIY projects, so this info should come in useful one day.
I'll add to this page over time as I fix the odd synth.
LCD's are pretty commonly found in older
synths. It is sometimes possible to restore older synths with
newer OLEDs , but you may wish to stay as close to the original.
For many instruments such as the Yamaha SY99 &
Korg Wavestation, there are no OLED replacements. They need LCD
display replacements.
LCD's are different to OLEDS.
LED LCD screens use a backlight to illuminate their pixels, while OLED's pixels actually produce their own light.
The back light commonly burns out.
Some of these LCDs had no backlight o
LCDs are thicker, heavier and consume more power than OLEDS.
1.VSS = GND
2. VDD = VCC = 5V
3. Vo = display contrast pin - you will often connect the wiper of a pot to this
4. RS = register select
5. RW = Read/Write
6. E = Enable
7 to 14. D0 to D7 = data pins
15. A = Anode - for the LED Backlight
16. K = Cathode - for the LED Backlight
I've used TinkerCad to test these circuits.
Example 1
This LED screen displays "Hello World"
Such a simple project.
These are the connections:
The resistor is 220 ohms
The pot is 250K ohms

LiquidCrystal Library - Hello World
Demonstrates the use of a 16x2 LCD display. The LiquidCrystal
library works with all LCD displays that are compatible with the
Hitachi HD44780 driver. There are many of them out there, and you
can usually tell them by the 16-pin interface.
This sketch prints "Hello World!" to the LCD
and shows the time.
The circuit:
* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 11
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground
* LCD VSS pin to ground
* LCD VCC pin to 5V
* 10K resistor:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)

Deluge loop sampling - Using drum & midi tracks
I think this is the best way to sample a loop using the deluge.
It maintains length & tempo as your recording is perfectly matched with the deluge.
You will need to make 3 tracks.
Method :
1. make 2 tracks
a) drum - gives the length & tempo
b) midi track - plays the synth (add your midi notes into the deluge sequencer)
2. plug Audio out from synth ---> into line in of Deluge
3. make an audio / recording track
a) press any track pad & press select
display will show "audio1".
b) press learn. & press the track again
The display will show left(dot) or stereo (dot) etc
The dot allows you to monitor
c) press select
4. press record button & check colour.
want purple / magenta.
5. Press record
6. Press play
7. press "Audition" pad or "play" to stop
***** NOTE *********
If the deluge is just sending midi clock to a synth with its own internal sequencer
you still need a midi track on the deluge to trigger your external synth. It can be left empty of notes.
The rest of the steps are the same as above.
-------------------------------------------------------------------
Recording a second audio clip
---------------------------------------------------------------
Recording alternative loops
so we can play one or the other,... but not both at the same time.
Press record & change the audition pad colour to red.

Arduino Dimmable LED - Linear Equations
Dimmable LED Project
This brings up the subject of Linear Equations.
0 to 1023 - this is the read value (potValue)
0 to 255 - this is the write value range. (LEDvalue)
we need to read one value range and convert to another value range.
Led Val = y axis
Pot Val = x axis
m= (y2 -y1)/(x2-x1)
m = (LED Val2 - LED val 1) / (pot val2 - potVal 1)
m = (255-0) / (1023-0) = 255/1023
or
y-y1 =m(x-x1)
or
LED Val - LED val 1 =m(pot val - potVal 1)
LED Val - 0 =m(pot val - 0)
LED Val =m(pot val)
LED Val =m * pot val
Thus
LED Val = (255/1023)pot val
The code:
------------------
// declare your variables
int potPin=A1;// 0 to 255
int gPin=6; // green pin
int potVal; // 0 to 1023 - potentiometer
float LEDVal; // will calculate it depending on potVal
void setup()
{
pinMode(potPin, INPUT);
pinMode(gPin, OUTPUT);
Serial.begin(9600); // opens serial monitor
}
void loop()
{
potVal=analogRead(potPin);
LEDVal=(255./1023.)*potVal;
analogWrite(gPin,LEDVal);
Serial.println(LEDVal);
}
int potPin=A1;// 0 to 255
int gPin=6; // green pin
int potVal; // 0 to 1023 - potentiometer
float LEDVal; // will calculate it depending on potVal
void setup()
{
pinMode(potPin, INPUT);
pinMode(gPin, OUTPUT);
Serial.begin(9600); // opens serial monitor
}
void loop()
{
potVal=analogRead(potPin);
LEDVal=(255./1023.)*potVal;
analogWrite(gPin,LEDVal);
Serial.println(LEDVal);
}
