The Roland TR-626 is more or less the big brother of the TR505 with exactly the same styling and operation but with 30 onboard sounds as opposed to the 505's rather tragic 16. It also features 8 individual outputs as standard, a TRIG output, a memory card slot and pitch control of the sounds, none of which featured on the 505. Despite all this its main similarity with the 505 is that its a rather bland machine, which is where we come in.

The modifications consist of:

24 way main patchbay: This feature enables the 626 to produce some savagely unlikely sounds. The main patchbay consists of 24 minijack sockets mounted on the top of the machine. Connections made between these sockets using standard minijack cables cause all kinds of sound swapping, distortion, pitching, ring modulation, envelope and odd mix effects to be applied to the sounds and patterns. Some connections will effect only one sound while others effect the whole mix. The amount of connections you can make at any one time is limited only by the number of patch cables you have.

2 Patchable switches: These two switches on the far right of the main patchbay are each associated with two minijack sockets each. Each switch can be patched 'in line' with any main patchbay connection allowing you to turn a connection on and off at the flick of a switch instead of having to repatch cables

2X3 way multiples: These two groups of three sockets on the right of the main patchbay act the same as a patching multiple you would find on a modular synthesiser. Each group of three sockets is connected together internally. This means that any signal present at one socket is also available at the other two. This feature is usefull for connecting one main patchbay socket to two other sockets or vice versa.
