Happy to report the updated SquishBoxes and kits are available in the Tindie store! The new update uses a custom PCB with SMT components, which means no need for a separate break-out board for the DAC, and an on-board switching voltage regulator that provides much steadier and more reliable power for your Raspberry Pi from … Read More
The Tindie store has been out of stock for a bit as I work on updating the PCB and making some adjustments to the code to improve performance (more on the code in a later post). I tried a new version of the PCB that moves the contrast potentiometer to the opposite side, where it … Read More
Here’s where things are at the moment. I made a batch of SquishBox kits and units available in the store, after a short delay waiting for parts and making some (I think) helpful modifications to the enclosure layout and updating instructions to match. They sold so quickly I think I might need to order a … Read More
I’ve been working on an update to the SquishBox that uses a rotary encoder instead of two buttons to switch patches, open menus, etc. One stompbutton remains, but is instead sends a MIDI message that can be routed to any function desired depending on the patch/bank settings. I’ve also added a status LED that can … Read More
I took some time to add and properly adjust a bunch of modulators in the ModSynth font. Now one has easy access to most of the useful synth parameters via CC messages – set your controller’s knobs/sliders to CC’s 71-90 and you can control the filter cutoff/resonance, volume and modulation envelopes, and modulation and vibrato … Read More
I devoted a couple days to some bash programming and wrote a script for Raspberry Pi that can install/configure everything for the SquishBox or headless Pi synth. The user selects some options, and the script can then install/update fluidpatcher, configure audio and startup settings, compile and install the latest FluidSynth, set up tinyfilemanager for uploading … Read More
Stickers arrived today! Now I feel like I can show finished images of the MidiFoot and StompByte, and work on getting build instructions for the kits up on Hackaday and building the Tindie store pages. Coming soon!
I sold out of my first batch of SquishBoxes that I built using standard perfboard, so I decided to get serious and print some PCBs. This will make the next batch of SquishBoxes a bit sturdier (and less expensive, since I can put them together more quickly and with less parts), and also lets me … Read More
FluidPatcher has had the wxpython-powered desktop implementation wxfluidpatcher.pyw for a bit, but I’ve added a couple things to make it more complete (e.g. settings menu) and written a simple implementation of Python’s socket library so it can remotely connect to a SquishBox or headless RPi synth – this means you can use it on Windows, … Read More
I’ve put together a headless implementation of FluidPatcher that works on a Raspberry Pi without the need for any extras (i.e. buttons/screens) by polling for specific CC messages to change patches. Just another way people can try out the code and come up with their own use cases. I like to think of someone just … Read More
