If you have suggestions for transient samples let me know.
Max length is 50ms in signed 8 bit pcm format
Should be royalty free material.
At the moment they will be hard coded into the firmware.
User sample upload via SD card may be a future update but is not planned yet.
Comments
There should be quite some flash memory left on the STM32.
So it would be possible to add custom waves/samples (like the 909 crash/cymbal you can select as an osc. waveform. But I think I won't address this until the current features are all working.
Firmware will be open source (but I think it will be a non commercial license).
I just have to tidy it up a little bit before uploading it to github.
