Roland TR-707 Rhythm Composer - Exclusive Soundgas HKA Modified Edition- SN 738009

Modified and expanded Roland TR-707 Rhythm Composer for sale with exclusive Soundgas HKA mod.

Supplied freshly serviced and modified with extra voice EPROM expansion from HKA Design, but for this one we've added four banks (of the eight) with our own sounds - an idiosyncratic selection culled from some of our favourite drum machines by our wizard synth tech, Chris.

This non-invasive, reversible mod allows switching between eight banks of sounds (it still operates exactly as a stock 707 at power up). Featuring new drum sounds in each kit. The last two sounds (707 crash + ride or 727 quijada + chime) remain the same across all banks, as they are stored on their own ROMs. The banks included are:

TR-707

TR-727

TR-808

TR-909

Soundgas Roland CR/TR (CR-78 & TR-66) - hear the first demo of this bank

Soundgas Korg favourites (KR-55 & Mini Pops 7)

Soundgas Elka/Maestro (Drummer One meets Rhythm King)

Soundgas Toy Box (Mattell + Casio)


Note that we will add more detailed info soon. All sounds are extracted from our own machines. Note that the limitations of the EPROM storage mean samples must be short and punchy (hence the cymbals having their own EPROM). This affects the choice of sounds to include, and also means you won't get a deep booming 808 kick.

Bank switching is done by pressing down one of the first 8 step keys whilst holding down the Enter key. The setting is remembered and will be recalled the next time it’s turned on. There are no modifications to the outside of the machine, and the installation is easily reversible.

Covered by our usual warranty.
