What is giabalanaipico

A sister product of giabalanai, a self-made keyboard kit of a split type MIDI keyboard that simulates Chromatic Button Accordion, has appeared. giabalanaipico is the same size as giabalanai, but the brain part is changed from Pro Micro to Raspberry Pi Pico. The Raspberry Pi Pico version has the following differences.

• Since the number of IOs increased, all keys on the right hand side became independent. The right-hand side of the C-System binding is now freed to allow B-System placement or any other key binding.
• Since the number of IOs has increased, it is now possible to implement a tact switch that can have up to 10 register switches (tone switching) functions on the left side and up to 7 on the right side (if used, a separate tact switch can be installed). Is required). In the past, it was necessary to press the layer button while pressing and holding the rotary encoder, but using a register switch may make it easier to change various settings during a performance.
• The good thing about Raspberry Pi Pico is that the firmware size limit is almost gone. The Pro Micro's FLASH memory is 32 kBytes, while the Raspberry Pi Pico's is 2 Mbytes. You can also include how to light up the LED MATRIX.

60 buttons (60 bass) + 10 tact switches can be attached to the left hand side for accompaniment, and 62 buttons + 1 rotary encoder (for system volume adjustment and mute) + 7 tact switches can be attached to the right hand side for melody performance.
It is also possible to illuminate the backlight of the button being pressed with an LED (separate LED required).

For the time being, it is designed to be a QWERTY array by changing the layer (bonus).
Since it supports REMAP, it is possible to easily change the keyboard layout. changes can be implemented without problems).

Items that need to be prepared separately

• Raspberry Pi Pico x2
• 20 pin 2.5 mm through x4. For Raspberry Pi Pico implementation
• Cherry MX compatible switch (5pin type recommended) x122
• MX compatible keycap x122
• TRRS cable x1
• microUSB cable x1 (The one that can communicate data. Please note that many cables attached to the charger cannot be used.)
• Soldering iron, tweezers, screwdriver, etc.
• Software that recognizes MIDI devices (Win: Piano 10, etc., Mac: GarageBand, etc.)

option

• Rotary encoder (with knob) x1 (for system volume adjustment, mode switching)
• Keyboard acrylic plate (For those who use 3-pin type key switches. It is very convenient if the key switch is positioned.) Click here for the keyboard acrylic plate for the left hand side.
• RGB LED SK6812mini-E x123 (if you want to illuminate the pressed key)
• giabalanai only supports SK6812mini, but giabalanaipico supports only SK6812mini-E. Please note that they are not compatible.
• Up to 17 tact switches (for register switches, as needed)

important point

• Never hot-swap a TRRS cable. If the 5 V wire in the TRRS cable touches the communication wire, the IO of the Raspberry Pi Pico will be damaged. The left and right boards will not be able to communicate with each other, and input from the left keyboard will not work.
• Also, be sure to insert the TRRS cable all the way in.
• Width x Depth = 28 cm x 10.5 cm on one side (same size on both sides). Almost 60% the same size as the keyboard. A fairly wide desk space (at least 60 cm) is required for performance.
• Please note that soldering is required.
• Not compatible with Kailh low profile switches. We also recommend a 5-pin type Cherry MX compatible key switch.
• As of 2021/11/13, QMK Firmware does not officially support Raspberry Pi. We use the sauce developed by Mr. Sekigon. Move QMK (unofficial) compatible with https://scrapbox.io/self-made-kbds-ja/RP2040
• The photo is a creation sample and is not the same as the product content.
• As of September 2020, in the MIDI function of QMK firmware, when the same sound is played with multiple buttons, the sound may sustain the sustain effect. Please note.
  ⇨ 2020/9/18 Fixed. but it's broken again on platforms with the latest firmware. See the build guide above for details on how to deal with this.
• I connect the left and right keyboards with TRRS cables, but I mix giabalanai (Pro Micro version) and giabalanaipico (Raspberry Pi Pico version). Please do not The Pro Micro operates at 5 V, and the Raspberry Pi Pico operates at 3.3 V, so there is a risk of damage due to a level mismatch on the serial signal line. but not).
