# info
|
|
|
|
this chip uses the [Generic Sample](../4-instrument/amiga.md) instrument editor.
|
|
|
|
- the maximum rate for sample playback is technically 31469Hz but anything higher than 28867Hz will sound glitchy on hardware.
|
|
- sample lengths and loop will be set to an even number.
|
|
- samples can't be longer than 131070. |
