was a range of MIDI percussion
controllers produced by the Roland Corporation.
The first model was the Pad-8.
The second model was the Pad-80 Octapad II. Again the Pad-80 was an eight pad MIDI
controller that allowed you to play various types of MIDI
sound sources..There was a few improvements to this second model including the larger memory that could store up to 64 different patches. Another 64 patches could be stored onto a Roland M-256E memory card. . Further improvements to the MIDI
specification included the control of modulation, pitch bend and aftertouch using a foot pedal.. The Pad-80 had a patch chain function that allowed a series of 32 patches to be arranged in any sequence, eight of these chains could be stored in memory..
Roland later released their SPD range which were similar to the Octapad range but included on board sounds and effects.
