    Wavetable synthesis, W25Q128JVSIM

    Hello, for a current project I am using the soundfont wavetable synthesis decoder to create wavetables and play them back using the 4.0 with audio-shield. Everything is working fine so far, however 512k is meager for even the leanest of sf2 banks. W25Q128JVSIM is mentioned as a possible source for more memory in this context, although I see it is not curently developed for the audio library as of yet. How trivial is this task? I would be up for writing one, if someone could point me in the right direction.

    Thanks for reading

    I would imagine an entirely different audio object would have to be made to do this, the current wavetable object uses a pointer to the address where the wavetable is stored which can't be emulated without using a special interface. On the upcoming T4 there will be space for two memory chips that can be added on the bottom that will add extra address space through FlexSPI that I believe can be used without any modification to the existing audio code since it's possible to use a pointer with that.

    Earlier this week I threw together a proof of concept of reading the wavetable files generated from the Soundfont Decoder from a SD card, which while it does offer more versatility since you can store as much as you want on an SD card it eats up the RAM since it has to store the wavetable in ram so that it can work with pointers. If you want a video of that working just ask and I can put my test setup back together to film it, the thread about that is here: https://forum.pjrc.com/threads/58735...s-From-SD-Card
    My example is only for the Teensy 3.6 and for only one voice, but I'm sure it could be modified for more voice and to work with a Teensy 4.0 I just don't have a breakout board to test it with.

    The chip I referenced is one of the ones that can be added as flash memory on the audio card, I believe. I had been thinking it would be advantageous to store a lightweight soundfont package on that to keep resources free. Eventually I would like to be able to connect 2 teensy 4.0 via i2s, and have the midi font as a custom input block for the audio tool.

    I do have a 3.6 as well, albeit w/o the audio shield. I was initially running all the code for midi on that, as it is easier to work with the soundfont editor library, but switched to 4.0 solely after reading the forums a bit and updating the 4.0 to show as a midi device. The soundfont on the 4.0 has been trickier, I'm trying to work out a few bugs at the moment.

    I will give your code a try, and will perhaps be able to adapt it to polyphony. If I can tailor it to suit my project, it could be the easier solution for now.

    cheers!

    I think I may have misunderstood the first part of your reply. A new version of the t4 is going to be released that has mem slots on the t4 board as opposed to the audio shield?

    Correct, but the memory slots aren’t just standard SPI like the audio shield, they are FlexSPI so they show up as address space which can be used to extend the ram or flash memory of the Teensy seamlessly without having to make calls to SPI to read and write to it. Meaning you can just declare a variable like you normally do with probably an extra keyword like DMAMEM to have it stored on the external chip and that means it works with pointers like any other variable.

    So I was trying to get the code going for the T4 but ended up getting with this compiler error, any thoughts on how to correct this?

    There is a problem with the converted files
    Each sample should be marked with PROGMEM:

    static const PROGMEM uint32_t samplename
    This prevent the whole sample to be copied to ram which runs out very fast @512kB
