CAN is a requirement.

The Teensy 4, its not just "3 CAN". It is 2x Classic CAN and 1x CAN FD. The RP2350 don't have CAN and ESP32 don't have CAN FD which rules out a lot of projects for me. I do like the ESP32P4 with DSI MIPI that can drive large display.

Onboard dual 12-16 bit DAC. The 4.0 lacks this while the 3.2 had one. Maybe use a cortex M55 or M85? Faster than the M7

Pico2's RP2350 (2x150MHz) is still HALF the speed of Teensy 4 (600MHz), has half RAM (520K vs 1M for Teensy) not to mention that Teensy 4 is way easier to program, so Teensy still has all advantages except the price.

Yes, it is dual core but each core is 150MHz. So as I wrote before it is 2x150MHz. It is HALF of performance of Teensy 4 and it is more difficult to program as when you really need those CPU cycles for single really complex real-time calculation...

If I went to a PICO, I would expect to use more of them. Right now, I hope to get at least 12 complex oscillators, 16 ADSRs, 16 LFOs, a huge mod-matrix, 12 PWM/CV outs and CAN commination on 1 TEENSY 4.0/4.1.

@h4yn0nnym0u5e: An update on my efforts to incorporate your modulation/tuning updates to the strings object. Once again, thank you for your efforts. I could never have accomplished this without your help. I struggled for a bit to get...

@h4yn0nnym0u5e "but I fear that anticipation has pretty much failed to materialise. Certainly the Teensyduino release cycle has extended massively, and very little repo maintenance has taken place. A couple of reasons for this have been more or...

FWIW: I have 16 voice polyphony, each voice 3 band-limited polyblep oscillators, 4 envelopes, 3LFOs, two ZDF filters with nonlinear saturation, flexible mod matrix, effects units all running on stock 600MHz Teensy 4 all in floating point written...

Some early videos are here (the thread is focused on my polyphonic after touch keyboard, but the sounds come from that teensy synth)...

@Michael Bachman, you're pretty much right, there's a distinct lack of new modules in the Audio library, though a fair amount of tweaking and bug-fixing has taken place. If you look at that repo you'll not only see that a lot of forks have been...

@h4yn0nnym0u5e . Sorry, I did not see any new modules in the Audio Library. As you implied, these updates/fixes are not well known. I will look around that repository more and see what necessary updates I might be missing. As much as I love...

Awesome. I have presently designed a polyphonic synth using the Teensy 3.2. All analog signal path. https://artisan-technology-workshop.com/iliad Tons of parts. I was thinking of using the Audio Library to replace just the analog...
