TR-707 ROM Expansion Kit

£57.00 GBP / Sold Out

Adds eight sound banks to the TR-707 or TR-727. Original sound sets from both machines included, so the modified machine can work exactly as stock. Fully reversible & invisible installation - doesn't require any holes drilled, track cuts, etc.

New for April 2022 - bank can be selected at any time (even while the pattern is playing) by holding down the ENTER button and pressing one of the first eight step keys.
