Thanks for all the input! I’ll have a play around with these approaches.

I have a question that I think is answered by this thread, so I’ll post my question and answer here and see if anyone can confirm it. Q: Should the AudioEffectWaveShaper’s shape() method use __disable_irq() / __enable_irq() ? A: Yes, otherwise...

Adding a 100ohm resistor solved the problem. I added it to the transmitting end of the SPI clock (next to Teensy pin 13). It eliminated the ringing from the clock signal transients and all the SPI devices are working fine without having to add...

Old thread, but I started seeing exactly this issue today (also using platformio). But I’m already using v1.110301.0 of the toolchain, and having tested my hardware with the same code compiled in Teensyduino vs. platformio I see the same “early...

Thanks! The enclosure is custom made from folded aluminium by a local company (near Oxford, UK). They laser cut the metal, fold it, add internal welded standoffs and powder coat it black. There’s another company nearby that screen prints the top...

@houtson thanks! The digipots do a few different things: variable resistance to control the PT2399 delay length, variable resistance to set the decay of the kick/tom/woodblock drum circuits as part of a Twin-T setup, and voltage dividers to set...

@tomas The audio performance is why I chose it – it sounds great! I’ve spent a lot of time playing 1960s transistor organs so I’m quite partial to a noisy signal. Digital delay is nice, but to my ears not very appropriate for a 1978-sounding drum...

FlasherX is a great resource! It still feels a little scary to swap the car out while you’re driving it, but since I got a good sequence of commands, responses and error handling in place on both sides of the serial port it has been extremely...

This is amazing. At first I thought it was weird that there was no obvious way to program a pattern, but I love the idea of making it "intelligent". I would probably get more use out of something this if I didn't spend time tweaking the pattern.

Earlier this year I finally launched a drum machine that I’ve been working on for a few years. It’s all based around a Teensy 4.1, and I learned a LOT from this forum along the way. I haven’t open sourced the code, but might do in the future when...

I don't know if this counts but it's running a Teensy 4.1 as the synth editor/controller.
