CHANNEL F, MIDI channel filter
This is used to rechannelize or filter MIDI data.
Connect the synth to the PRO-4 MIDI out socket, and set the MIDI filter receive channel to the MIDI
channel music data you want your old synth to respond to. Only data received on that channel will be
sent out of the PRO-4 MIDI out, and any other channels will be filtered out. This data can be sent out on a
different channel if required (see rechannellizing above). An example of rechannelizing might be to
change the transmit channel of early DX7s, for instance, that can only transmit on MIDI channel 1, to
another MIDI channel, say 2. An example of filtering might be on an early MIDI synth that can only
receive in Omni mode (receive on all MIDI channels at the same time), the Jupiter 6, for example.
CHANNEL G, the DCB port
DCB (digital communications bus) is an old digital port Roland designed for linking up their poly synths,
such as the Juno 60 or some Jupiter 8s. This is a polyphonic interface. It only sends note information, but
on Jupiter 8s with DCB, it will also do program changes.
CHANNEL H, the KADI port
The KADI (Kenton Auxiliary Digital Interface) is a digital port. This can be used to play the TR606 or TR808
drum sounds over MIDI, although a small modification will have to be made to the drum machine.
It is also there for any possible future expansion. Note, special cables are needed to use the Wasp, DCB &
KADI ports. These are available direct from Kenton.
SYNC 24 & Clock Pulse
The PRO-4 has a Roland SYNC 24 clock output. Instruments having a SYNC 24 input, such as the TB303,
TR808, TR606, MC202, can be connected to the PRO-4. If the PRO-4 is receiving MIDI clock, these
instruments will play their internal patterns in time to MIDI clock.
The PRO-4 also has a clock pulse (arpeggio output). This can be used to synchronize drum machines,
analogue sequencers, and arpeggio`s to MIDI clock.
