Hello all, I wrote some rotines to erase, create a directory, list files, write and read int16_t[256] arrays on an SD card using the SdFat.h library but when I load the audio.h library at the same time, I have compilation errors. Is there a way to bypass the incompatibility of these two...

I have been using Duppa products in my projects for a long time. They work very well and allow you to connect many encoders with only 2 pins of the Teensy. Duppa also sells very easy to use i2c led rings.

For info, there are primitives: midihost.idVendor() midihost.idProduct() with for example: idVendor Akai = 0x9E8 idProduct Midi Mix = 0x31 idProduct MPK Mini Plus = 0x54 idVendor BEHRINGER = 0x1397 idProduct X TOUCH MINI = 0xB3 idVendor fighter_twister = 0x2580 idProduct fighter_twister = 0x7...

I am myself currently developing a very similar project, which uses an Akai MPK miniplus with eight encoders as a controller, a stg5000 card and an ili9488 screen.

Nice project, I have a question, why are the waveform tables sized [257] while the audio library oscillators expect [256]?

Is it possible to have multiple USB device ports on Teensy 4.1?

Yes, I suspected that this was the cause, but when I connect the iPhone to the MacBook, I also have two hosts.

Hello everyone, I am using touchOSC installed on an iPhone 16 Pro Max. I created a template that works to control my Synth on Teensy 4.1 using the Audio library. When I connect my Akai controller to USB Host using the USBHost_t36.h library it works fine. When I connect my iPhone to my MacBook, I...

Thank you for your reply.

If I understand correctly, the pulseWitdth() class does not exist on a waveformMod object but we can modulate the PWM with an LFO, If I use a waveform object, the pulseWitdth() class exists but no modulation possibility. So there is no solution to do both at the same time with a single oscillator?

Hello all, I am currently developing an 8-channel synth using Teensy 4.1, SGT5000 and the audio.h library. Instead of creating eight independent channels, is it possible to index the name of the different modules (oscillator, envelope, filter), so that I can write, for example VCA_ENV.noteOn()...

the problem with a hub is that the order of the devices is never the same and depends on the order of their connection. So I never know who I'm talking to.

Hello everyone, I am developing a midi router with a Teensy 4.1. For the midi host, I use the USBHost_t36.h library and my program works well. I have a question about the hardware, is it possible to have several usb host connectors? And to assign them to hub1, hub2...? In the following...

Thank you very much BriComp, it's very clear. I tested it and it works fine.

Hello all, If I understand correctly, it is possible to power a Teensy LC board with 5v on the Vin pin? If I do this, is it still possible to use the USB cable for programming or will I have a 5V power conflict?
