1) Above is a list of how program numbers are used in MAPPING MODE. No matter how the sounds are assigned,
these program numbers always belong to the same sound. (N.B. this assumes programs start at 1 rather than 0)
2) Any program number above 11 will terminate Mapping mode and return you to normal play mode.
3) You can assign more than one sound to the same MIDI note, all of them if you want, however MIDI out uses the
same map, so all sounds would then generate the same note!
4) Assignments are stored in non volatile memory.
5) The TR-808 will always transmit the assigned drum notes as follows:- Normal notes - velocity 64.
Accented notes - velocity 127.
6) Receive Mode 1 - (factory default setting). The TR-808 will play the assigned note at the incoming velocity.
7) Receive Mode 0 - The TR-808 will play the assigned note in two ways only. Received velocity 1 to 63 – will play
normal volume, received velocity 64 to 127 will play an accented sound which is adjustable by the Accent control on
the TR-808. This mode is provided so that patterns/songs sent from the TR-808 to a separate sequencer and
stored, can be played back exactly as if they were in the TR-808.
8) Modes 0/1 can be changed from within a song/sequence by sending a "General purpose controller 1" message.
In hexadecimal 0Bxh – 10h - nn
Where B is Controller status (0B0 hex)
Where x is the current MIDI receive channel (0 to F hex)
Where 10h is controller number 16 (10 hex) [general purpose controller 1]
Where nn is 64 (40 hex) or more for mode 1 - (velocity mode)
Where nn is 63 (3F hex) or less for mode 0 - (accent mode)
9) "MIDI CONTINUE" is treated as a "START" command if Song Position Pointer is zero. (default)
If seleceted, Continue messages can always be treated as Start.
10) When the TR-808 is receiving clock via MIDI the rear panel din sync socket will also carry the decoded MIDI
clock and stop start control signals - enabling another TR-808 or TB-303 to run in sync with the incoming MIDI.
11) For the TR-808 to run correctly from MIDI sync, you will need to use PRE-SCALE setting number 3
(quarter notes).
SETTING PRE-SCALE –
set pre-scale switch to 3
set to pattern write 1st part
select pattern you want to change
press start button
press clear/pre-scale button until change is heard
press stop
reset to pattern play
done
