What's new v1.1a/v2.1a (2024)?

1. Turn cc while arpeggio ON

While an arpeggio is playing, turning a continuous controller caused stuck Note On messages. This has been fixed.

2. Un-block the code

When in the menu, pressing a key or turning a continuous controller was "blocked", meaning that the keyboard or potentiometers do nothing until the menu item currently being selected was set by clicking the encoder. Now, anywhere in the menu selection key presses and potentiometer turns will work.

3. Change keyboard mode while a key is held

If a key is held and the KEYBOARD MODE is changed, it waits for the key release and then changes the KEYBOARD MODE.

4. Digit brightness

Now the 7 segment digital display has a consistent brightness and is updated at 100 Hz. The only exception is when ARPEGGIO is ON. There is some display flicker while an arpeggio is playing due to the increased CPU load on the microcontroller. Releasing the arpeggio eliminates any flicker in the display.

5. Noisy potentiometers

Potentiometers sometimes sent random control changes when no continuous controller was being turned. This has been fixed.

What's new v1.0a/v2.0a (2023)?

1. Firmware can be compiled for any PCB version
2. 7 segment display flicker fixed
3. Potentiometer latency can be adjusted
4. Rotary encoder polarity
5. Pentatonic Major and Pentatonic Minor scales
6. Quick transpose
7. MIDI Arpeggiator

Note: new versions of MPLAB X and the XC8 compiler do not work!

Please use the following ide, compiler and the necessary peripheral library

MPLAB X v4.05

XC8 v1.45

PIC18F Legacy Peripheral Libraries v2.0

After installing all of these, you will have to link the peripheral library.

1. right click the project name
2. select "Properties"
3. under "XC8 global options", select "XC8 linker"
4. scroll down and check "Link in Peripheral Library"
5. the program should compile now
