6.7 Parallel
6.7.1 General Description
Parallel is a 4-way output interface. The first 4 channels have their own individual
output which means that only a maximum of 4 channels can be used. If a note is
recognised the relevant Vend line is set to low for a period of 100 ± 3ms. Pulses
outside these limits should be rejected as a precaution against false triggering.
Caution!
Parallel is an unsecure interface
and should not be used for new
developments!
