REDRUM a drum breakbeat sampler for Game Boy

Can be played on original hardware or in an emulator.
This is a sample smasher based on "Amenizer" 

You can hear it here:

While the loop is playing, the ROM sends out an LSDj compatible sync signal on the link port.

You can apply effects by holding either B or A, or both (A enables a stutter effect, B enables a granular/repeater).

Effect values can not be changed while one direction on the D-Pad is held down. The purpose of this is that you could be able to “roll” around on the D-Pad to mash the beat while an effect is triggered without changing the effect values.

You can also press Select+Start to enable a “special” effect. When this effect is active, the pitch of the wave channel does not follow the general pitch of the loop. This causes a phasing type effect when adjusting the pitch.

Start - Start/Stop playback of the loop

Select+Up/Down - Pitch loop

D-Pad - Rearrange the loop in 16th “slices”

B+Up/Down - Control the repeat size

A+Left/Right - Control the stutter length

Select+Start - Enable a “special” effect
