3 Connections
3.2 Outputs
3.2.1 Midi Outputs
Each clock channel has its separate Midi output. Each of these outputs is assigned to one port
of the ACMEs
. This allows the merging of computer-generated Midi commands
into the clock streams generated by the ACME-4.
3.2.2 DIN-Sync/Midi Outputs
Clock channels 1 and 2 have extra outputs labeled “Sync/Midi”. They can be set to either act as
a second Midi output for their channel, or to supply DIN-sync signals.
Note!
The DIN-Sync standard does not support all functions of the ACME-4.
3.2.3 Clock/Reset Outputs
Clock channels 3 and 4 have extra jack outputs labeled “Clock/Reset”. These jacks are stereo.
On the left channel (tip) an analog clock is send out, while the right channel (ring) supplies a reset
signal. Polarity of these signals can be selected, as well as the clock divider.
The reset signal is produced when one of the 3 master clock sources is started, and also every
time a clock channel - having been stopped using the channels “Run/Halt” button - is restarted.
Matching cables (stereo jack to two mono jacks) are often referred to as “insert cables”, and can
be obtained from many sources. If only the clock signal is needed, normal mono cables can be used
since the reset output - like all outputs of the ACME-4 - is short-circuit-proof.
Note!
DIN-sync and analog clocks - unlike Midi connections - do not provide what is called “galvanic
separation” between devices, and thus are prone to cause ground loops. In the ACME-4 special
provisions have been made to prevent that from happening.
