Hello,
i am a professional bass player from Berlin and i m trying to upgrade my guitar by adding a teensy 3.6 and trellis (look here ). Everything works fine exept the the beginFreeze() . It work on 3.2 but i want to work with samples this is why i decided to use the 3.6 (more memory, faster). Any why nothing is happening when i am activating beginFreeze()? Do i need somthing like a debounce function for the trellis pad? if so do you know how to write that? here is the code. THX hottib
