Hi Pete

Does the transpose function work on rotary encoder addresses?

To change the panning from the address i set to another address

This way i can activate/deactivate the encoder button top and adjust the lh or rh panning function in a dual pan setup?

Cheers

Yes. Transpose is just a special version of Bank, so it's probably better to use Transposer for notes, and Bank for everything else.

I don't really understand your question, but all elements have enable and disable methods.

Hi Pete

i am trying to give the mackie control a try, but i cannot get the fader to work it is outputting the cc change on channel 1 address 7 but when it is mapped as a mackie control i get no fader movement in cubase

can you check my code below to make sure it is correct with the current release, i have no idea what is going on
i have even downloaded and installed the controlsurface library again

#include <Encoder.h>
#include <Control_Surface.h>

// Instantiate a MIDI over USB interface.
USBMIDI_Interface midi;

// Create a new instance of the class CCPotentiometer, called potentiometer,
// on pin A0, that sends MIDI messages with controller 7 (channel volume)
// on channel 1.
CCPotentiometer potentiometer(A0, {MIDI_CC::Channel_Volume, CHANNEL_1});

CCRotaryEncoder enc = {
{2, 3},
MCU::V_POT_1,
2,
4,
};

void setup() {
// Use the Mackie Control protocol for sending relative MIDI CC messages.
RelativeCCSender::setMode(MACKIE_CONTROL_RELATIVE);
Control_Surface.begin(); // Initialize Control Surface
}

void loop() {
// Update the control surface
Control_Surface.loop();
}

i know it seems stupid
i am wondering if there is a problem with the way my mackie control is working in cubase
not the controller
i am getting a cc message correctly in midi ox
so it should work

Fader movement in MCU uses Pitch Bend events, so you need a PBPotentiometer.

Hi Peter

Just trying to get a bankable LEDs shift register working
is this possible

Bank<2> bank(1); // Create a new bank with 1 tracks per bank

IncrementDecrementSelector<2> bankselector(bank, {8, 9}); 

ShiftRegisterOut<8> sr2(dataPin2, clockPin2, latchPin2, MSBFIRST);

Bankable::MIDINoteLED leds[] = { 
    bank,
        {{
            {sr2.pin(0), note(E, 2)}, CHANNEL_1}},
            {sr2.pin(1), {note(F, 2), CHANNEL_1}},
            {sr2.pin(2), {note(Gb, 2), CHANNEL_1}},
            {sr2.pin(3), {note(G, 2), CHANNEL_1}}, 
            {sr2.pin(4), {note(Ab, 2), CHANNEL_1}},
            {sr2.pin(5), {note(A, 2), CHANNEL_1}},
            {sr2.pin(6), {note(Bb, 2), CHANNEL_1}},
            {sr2.pin(7), {note(B, 2), CHANNEL_1}},
        }},    
};

Update to ee43f15 and try this:

#include <Control_Surface.h>

USBMIDI_Interface midi;

Bank<2> bank(1); // Create a new bank with 1 tracks per bank

IncrementDecrementSelector<2> bankselector(bank, {8, 9}); 

// There's no need to use different clock and data pins for each shift register,
// Either daisy chain them (i.e. use one 16-bit instance instead of two 8-bit instances)
// or share the data and clock pins, using just a different latch pin for each register.
// Daisy chaining them is preferred, see https://tttapa.github.io/Control-Surface/Doc/Doxygen/d3/d82/Ex_81_8Shift-Register-LED-Effects_8ino-example.html
// It's also much more efficient and faster if you use the SPI bus for the shift 
// registers (8 MHz), and it also saves some pins.
SPIShiftRegisterOut<8> sr2(SS, MSBFIRST);

using namespace MIDI_Notes;

Bankable::MIDINoteLED<2> leds[] = { 
    {{bank, BankType::CHANGE_CHANNEL}, sr2.pin(0), {note(E, 2), CHANNEL_1}},
    {{bank, BankType::CHANGE_CHANNEL}, sr2.pin(1), {note(F, 2), CHANNEL_1}},
    {{bank, BankType::CHANGE_CHANNEL}, sr2.pin(2), {note(Gb, 2), CHANNEL_1}},
    {{bank, BankType::CHANGE_CHANNEL}, sr2.pin(3), {note(G, 2), CHANNEL_1}}, 
    {{bank, BankType::CHANGE_CHANNEL}, sr2.pin(4), {note(Ab, 2), CHANNEL_1}},
    {{bank, BankType::CHANGE_CHANNEL}, sr2.pin(5), {note(A, 2), CHANNEL_1}},
    {{bank, BankType::CHANGE_CHANNEL}, sr2.pin(6), {note(Bb, 2), CHANNEL_1}},
    {{bank, BankType::CHANGE_CHANNEL}, sr2.pin(7), {note(B, 2), CHANNEL_1}},
};

void setup() {
  Control_Surface.begin();
}

void loop() {
  Control_Surface.loop();
}

Hi Pete

Yep it works really well
now my fader module has a 2 bank function i can map as i please with corresponding leds
and i have the encoder in bank 1 as "LR mono pan" and in bank 2 it controls the "LR stereo combined panner".

I saw somewhere a bank indicator led function (to let you know which bank it is on)
but i cant seem to find it in the docs
if you could point me in the right direction that would be much appreciated

Nice work dude, yet again you are the man

code i have loaded at the moment below:

#include <Encoder.h>
#include <Control_Surface.h>



// Instantiate a MIDI over USB interface.
USBMIDI_Interface midi;


const pin_t dataPin2  = 23;  // Pin connected to DS of 74HC595 yellow wire
const pin_t clockPin2 = 25;  // Pin connected to SH_CP of 74HC595 green wire
const pin_t latchPin2 = 27;  // Pin connected to ST_CP of 74HC595 blue wire

// Create a new shift register output connected to pins 12, 13 and 10,
// shift the data out with the most significant bit first.
// There are 8 outputs in total.
SPIShiftRegisterOut<12> sr(SS, MSBFIRST);
ShiftRegisterOut<8> sr2(dataPin2, clockPin2, latchPin2, MSBFIRST);

uint8_t track = 1;
Channel channel = CHANNEL_1;
// Note: a VU meter of 12 LEDs will give the best effect, because
// in the MCU protocol, there are 12 values
// from cubase needs to be set as aftertouch on correct channel and set max value to 12 or 24
MCU::VULEDs<12> vu = { 
  {track, channel}, 
  {{
    sr.pin(0),
    sr.pin(1),
    sr.pin(2),
    sr.pin(3),

};

CCPotentiometer potentiometer(A0, {0x07, CHANNEL_1}); // working 

Bank<2> bank(16); // Create a new bank with 16 tracks per bank

IncrementDecrementSelector<2> bankselector(bank, {8, 9}); // does loop back to original setting from one button

You can use IncrementSelectorLEDs. (There's IncrementDecrementSelectorLEDs as well, but it's not really useful if you only have 2 banks.)

I noticed that the transposer example, lets only the user choose the +or- semitones limit , but the sketch coud also have the "steps" variable, in it, in the case he wants to transpose a whole octave at each +or- transposer button press.
In my case, my controller has only 8 note buttons, so I changed the steps to 8 in the library, so I can cover the whole keyboard. Supposing the user had a 1 ocatve keyboard, the step need to be 12,
SKETCH -> Transposer<-6, +6> transposer;
Library _> Transposer(int8_t step = 8)
