A device that uses the duration of a music disc to sort discs with the same signal strength.

Features

• Includes schematicDefinition: Typically a .litematic file or a .schematic file in older versions or with different mods than litematica. It is a blueprint that tells you how to build redstone builds, tells you what materials yo... for a hopperspeedDefinition: Refers to the speed at which items are processed in a hopper (1 item every 8gt, or 2.5 items per second). Usually written as an integer (e.g. '3x hopper speed'). ## Common hopperspeeds 1x: 9000 ite... prechecker device which checks if an item is a musc disc and has a signal strength of 9-14 first before sending to length based sorter.
• Can discriminate strad, wait, 11, ward, otherside, pigstep, relic, precipice, creator (music box version), creator, lava chicken, and tears music discs.

Considerations

• The Prechecker and the length sorter can be fully hopperlockedDefinition: Hopper-locking powers inactive hoppers with redstone to prevent them from doing anything, reducing lag. Because a locked hopper can’t move items, it can skip several expensive checks each tick and ... with additional wiring, but is not included in the schematic
• Prechecker has an idle cart

Notes

The magenta glazed terracotta in the sorter part are discs that need swapping in the output stream for proper arrangement in the ROM. Works with all discs from 1.21.8 and below, do not change rom as it needs to be ordered in a certain way
