CANFORD MIDI AC MAINS POWER SWITCHER
A free-standing unit that allows any mains-powered equipment such as signal-lights, pyrotechnics, etc., to be switched under MIDI control. Six different operating modes may be selected, including note velocity (>63=“on”), note-on/note-off, controller value, note-on toggle, thus allowing operation from all types of MIDI controller (synthesiser, sequencer, etc) including those which do not send “note-off” information. Settings can be controlled remotely using MIDI commands or by a local default, set by 16 DIL switches:
| Switch |
Function |
Notes |
| 1-3 |
Mode |
Defines the operating mode (1-6) |
| 4-7 |
Channel |
Defines which MIDI channel is used to listen for messages (1-16) |
| 8-15 |
Value |
Defines note/controller value the switch will respond to (1-128) |
| 16 |
Omni |
When set allows the unit to respond to any channel. |
Operating any default switch automatically resets the unit to the new default, and there is also a reset switch to set the unit to the current default. Mains switching occurs at the zero-crossing point of the mains cycle, which, together with spike suppression components, ensures that interference is virtually eliminated. Mains inlet and switched output are on IEC connectors and MIDI-IN and THRU connections are provided, allowing the switcher to be connected in line with other equipment. LED indicators show input and switched mains power, MIDI data present, omni and mode status.
