Table6 – FAQ & troubleshooting
Problem:
Solution:
The device doesn't receive
MIDI data at all.
Set SYNC switch on rear panel of TR-808 instrument to middle
position.
Use special MIDI cable delivered with the interface. The interface
doesn't work with standard MIDI cable!
The device doesn't receive
MIDI Notes.
Check if MIDI Notes are sent on acceptable MIDI channel (channel
Nr. 10 is default after Factory Reset).
Be sure that used MIDI notes are assigned to an instrument (sound
generator) of TR-808 - check instrument map of the interface.
The device can't be synced
with MIDI clock.
Check if transmission of MIDI clock is enabled on your sequencer.
Be sure that the interface is switched (with Program Change MIDI
command) to program which enables receiving of MIDI clock. Only
programs Nr. 2, 4, 6, 8, 10, and 12 have that possibility after Factory
Reset.
More instruments (drums) of
TR-808 are sounding
simultaneously when only
one MIDI note is transmitted
to the interface.
Try to calibrate DA converter of the interface as described in
installation manual.
