As the holidays approach, we’re excited to share something we’ve been working on here at Blokas HQ.
We present Pimidi – a stackable 2×2 MIDI interface HAT for Raspberry Pi and pimidipy – a Python library to make MIDI processing rather effortless!
We created these two primarily for makers and MIDI enthusiasts seeking total flexibility. Together, they’re designed to handle even the most demanding MIDI scenarios!
We’re launching Pimidi and pimidipy as a Beta program for our community, and we’d love for you to join in!
What makes Pimidi HAT awesome?
- Compact: Pimidi comes with 4 mini jacks following the official MIDI pinout standard (Type A).
- Stackable: Connect up to 4 Pimidi boards together for 8 inputs and 8 outputs. Perfect for bigger MIDI setups.
- Ultra-Low Latency: 1.28ms loopback latency using direct I²C communication – great for real-time performance.
- Minimal GPIO Usage: Pimidi only uses I²C and 2 GPIO pins, leaving the rest free for your custom projects.
- Activity LEDs: Dedicated LEDs for every input/output port to easily monitor MIDI data flows.
Paired with Raspberry Pi’s USB ports for USB-MIDI, MIDI-over-Bluetooth, and MIDI-over-network, Pimidi will transform your Raspberry Pi into a complete MIDI connectivity hub!
Enter the pimidipy Python library
- Simple API: Easy to use, even for complex workflows like generative MIDI effects or advanced routings. You can find script examples here.
- Universal: Works on all Linux-based environments and is compatible with any MIDI interface or device. Plus, it automatically handles device disconnects and reconnects.
- Open-Source: The community can explore, customize, and enhance it to meet broader needs.
- Shareable: Download and tweak community-made scripts from Patchstorage.com or share your own to inspire others!
We have also created a pimidipy Patchbox OS module to handle script auto-launching, so you can focus on making music, not connections!
Beta Program & Pimidi Early-Birds!
You can start experimenting with the pimidipy library right away – install it via pip or as a Patchbox OS module. We’re looking to expand the example section on Patchstorage, so let us know what scenarios or features you’d like to see covered!
If you’re interested in the Pimidi HAT, our initial batch is ready, and we’re offering an early bird price of 40.5€ (25% off the 54€ MSRP). Don’t miss out – it’s available for our community via THIS LINK ONLY: https://blokas.io/store/?secret=blokasfam.
Dive in and share your feedback – we can’t wait to see what you’ll create!
Cheers, and happy holiday season!
