I’ve looked for info in the Teletype documentation and tried Googling it but I cannot find reference or a hint of how many Scenes can be stored in Teletype’s flash memory?
Current limit is 32, but there is talk of it being reduced to 16 to permit a storage-heavy feature to be implemented in a future release.
The USB filesystem is undergoing a rewrite, so that will likely permit live scene loading from a USB stick.
