Kenton CR-68 - Manual

INSTRUCTIONS FOR MIDI INTERFACE
ROLAND CR-68 DRUM MACHINE
These instructions are for CR-68 MIDI retrofit kits produced after 29
th
August 2013 – Firmware CR682105 or later.
Different instructions apply to earlier CR-68 MIDI retrofit kits.
Your CR-68 drum machine is now equipped to send and receive MIDI information. When turned on the will function
normally but will also send and receive MIDI note & velocity information on the channels set in memory. It will also
send and receive MIDI clock information. The velocity data conveys accented or unaccented note data only.
The factory default settings are:
Receive channel 10 omni off / Transmit channel 10 / Stop/start receive enabled
You can return to the factory default settings at any time by turning the CR-68 on while holding the red push button
pressed. Hold for a couple of seconds – then release.
If the CR-68 is already playing from its internal clock, then all MIDI clock commands are ignored. If the CR-68 is
stopped, then when a MIDI Start command** is received, the CR-68 will take its timing information from the MIDI
clock source. If the start button on the CR-68 is then pressed, it will be ignored until a MIDI stop command has been
received. ** (or SPP = zero + continue – see below)
Many sequencers do not send a MIDI start command and instead send a Song Position Pointer zero followed by
Continue message. This is recognised by the CR-68 as a MIDI start. Continue messages received at any other time
will be ignored. If however you want Continue messages to be always treated as Start, this can be selected.
You can make the CR-68 ignore start/stop/continue/clock commands by selecting it from the programming mode
described in the next paragraph, when set to disable the CR-68 will not respond to start, stop, continue or clock
commands, this is to enable the CR-68 to function as a sound module in systems where MIDI clock is being used to
drive other devices.
You can set the CR-68 to MIDI receive OFF, this will enable the CR-68 to run in time with MIDI clock, but ignore any
incoming notes.
Using the red push button to program the MIDI settings
Two modes are available by pushing the red push button. Before you do press the red button however, make sure
the CR-68 drum is not playing, otherwise the results may be unpredictable.
1) SETUP MODE - Setting MIDI channels and assignments (start-stop etc)
Give the red push button a short press (half a second) - then release. Follow this with a note or sequence of notes
(on the remote keyboard) as detailed on page 2. After selecting a MIDI channel (receive or transmit) you will be
automatically returned to playing mode, but after making any other assignments you will need to press the ENTER
key (Top C on a 61 note keyboard) to return to playing mode. (N.B. set-ups are stored in non volatile memory).
2) MAPPING MODE - assigning MIDI notes to sounds
Press the red button hold for about four seconds - then release. Follow this (on the remote keyboard) with a
program change number, then any MIDI note. The drum sound specified by that program change number will be
mapped to the key you pressed. You may keep assigning drum sounds to keys in the same fashion (program then
key). When you have assigned all the sounds that you want to, press any invalid program change number (12 and
above), you will then be automatically returned to normal play mode. On page 3 is a list of which program numbers
correspond to what drum sounds.
Note: When in setup and mapping modes the CR-68 will receive on ALL MIDI channels.
