Roland 100m 184 Keyboard

via this auction
"This is the largest and most specified of the 100M keyboards. Although there are the same number of keys as the 181, i.e. 49 keys 4-octaves, the action is definitely an improvement on the other models. It has all the features of the 181 keyboard except for the 6 pin DIN socket. Power is via a captive mains lead, & not from the rack. It does have a number of useful additions over the 181. There is an arpeggiator with a rate control and hold, and four push buttons for selecting Up, Down, Up&Down, or Random modes. Plus an arpeggiator clock input on the rear for connecting to a drum machine or sequencer trigger output. There are 4 assign mode buttons for selecting two Unison (monophonic) modes and two Poly (4 voice) modes of playing. Next to these buttons is a hold (sustain) switch. The bender also has a pitch bend sensitivity knob. The Pitch Bend lever affects the notes played, and also has a dedicated CV output. The return to zero spring-loaded lever is very accurate and I find it much easier to use than the Doepfer Joystick, for example. The transpose switch only has two positions on this model, normal and 1 octave down. There is a knob for portamento which can be switched in or out. Along the rear of the keyboard are 4 CV and 5 Gate outputs. The fifth gate socket is a combined output of gates 1-4. and all the outputs are duplicated on mini and standard jack sockets which can be used simultaneously."
