TR-707 ROM Expansion
£60.00 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.
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. The new Rev. 2 board also allows banks to be selected with MIDI Program Change messages on MIDI channel 10.
