v1.5.4 device struct

• new CIP 6.1. kernel tested on Pi1 and eeepc successfully
• code more modular
• ready for unit-testing, doxygen, ...

v1.5.2 pi1 only

Pi1 only

• mainstream linux-cip-6.1.157-cip48-rt26
• delay still high
• bug: no hdmi output (I think)
• search an event with valid input from a keyboard
• pitchbend 4 half notes (not 2)
• semi fix for longpress 0 for sustain
• handmade modules load after autologin (again)
• remove idea to use my own pi1_defconfig
• feature to change frequency up/down on release

v1.5.1 realtime CIP Kernel

pi delay: 64ms

eeepc delay: 48ms

• pi and eeepc both with linux5.10.162-cip24-rt10
• rt support (mainstream 5.2023)
• not pi kernel (custom 4.2024)
• remove libasound
• New way to build via buildroot (pi1_defconfig)

Pitch Bend Pi1

New application startup, pitch bend feature, but still 70ms delay :-(

I am still working on an eeepc version.

You need min. 64MB sd card for that image in e.g. /dev/mmcblk0. Write with:

gunzip pi1-miniMidiOut-v1.4.2-sdcard.img.gz
sudo dd if=pi1-miniMidiOut-v1.4.2-sdcard.img of=/dev/mmcblk0

v1.4.0 - ready to use images for Pi1 and eeepc

• it use the first midi keyboard pluged into a USB-Port as input device
• optional (pi1): it use the first "letter" keyboard or numpad pluged into a USB-Port and wait for keypress to change e.g. the waveform
  • on eeepc the number keys on the device are used (and . for octave up, - for octave down)
• plug them in before you boot!

pi1

Just format a SD-Card (min. 62MB) FAT32 and copy the content of the 7z file to it. The Pi1 will boot from it and autostart miniMidiOut.

Known issues on Pi1:

• hotplug USB-MIDI device will not work, until you add dwc_otg.speed=1 to the cmdline.txt
• if you add dwc_otg.speed=1, a USB numpad/keyboard will not work

eeepc 4G (701)

Write the eeepc image to SD-Card (e.g. /dev/sdY):

gunzip -c /path/to/eeepc.img.gz | sudo dd of=/dev/sdY bs=4M
