A sequencer is a tool used for control synthesizers, sound modules and any devices which have MIDI connectors. It sends and receives standard MIDI messages. It is a description of a device based on a sequencer from: **broken link removed**. It is a new version, which was improved by:
USB support
software downloading
MIDI – 4 ports
2 sets of standard MIDI
network and SD card connector
If you have one of previous versions (for example v2), you only need to change the control board with the software to get described here MIDBOX V4 sequencer. All switches and encoders are connected in the same way as in v2. Descriptions on the faceplate should also be changed to new ones, because they are assigned to different functions in software.
