Roland TR-707 Drum machine with both HKA V2 ROM Expansion and Cymbals Board

Description

Roland TR-707 Drum machine with both the HKA V2 ROM Expansion and the HKA Cymbals Board. The V2 Expansion allows you to change the sounds without re-booting the machine. This 707 is in very good condition and comes with a UK compatible PSU. Check the HKA design design for more in-depth info on these expansions. If you're going to have an expanded TR 707 it is define toy worth having the additional Cymbals board. Please contact me before purchase for overseas shipping cost outside the UK. Will ship with full insurance cover. The 8 banks included with the HKA Expansion are : TR-707 TR-727 TR-808 TR-909 LinnDrum LM-1 DMX TR-707 + TR-727 mix (handy for those who don’t own both machines) TR-707 Cymbals BoardIntroduction This is an add-on board for the TR-707 ROM Expansion, which addresses the shortcoming that it cannot change the last two sounds on the machine (either the crash/ride cymbal on the TR-707, or the quijada/chime on the TR-727). The reason for this is because unlike the rest of the sounds, which are all stored together in one block of memory, the cymbals are stored in their own separate ROMs, with their own address counters and DACs.
