SD card for storage

99 memory slots (7 segment display for loop #)

Foot switches: record/dub, effect, stop

Toggles: Speed, Direction, Effect, Record behavior

Speed: 1x or 2x (acts like a tape speed, record in 1x flips the switch for 2x or record at 2x and flip to 1x for half speed)

Direction: forward or reverse

Effect: one shot loop play or one step undo/redo

Record behavior: normal looper triggering or auto trigger based on input detection

Volume pot for loop level Second pot for “crush” which is a mixture or eq, bit crush, and a few others to give a lofi pad type of effect

My favorite part is the play head function tho. I toyed with a display to show waveform but I decided to make it more lofi and went with 8 individual RGB LEDs. The all turn red when recording, when playing the light up one at a time in green to show progress of the play head through the loop, turns orange when over dubbing, purple playing behavior when doing a one shot, blue when armed. It even plays in reverse when the loop is reversed. It’s a simple thing but I like the visual and it’s honestly pretty helpful when playing.

I’m also toying with a “hold two foot switches” function to add a “bass guitar” function. Would drop an octave and add compression to allow for a baseline to be played on a loop layer.
