CLOCKstep:MULTI
External Clock Sync (con nued)
The 'Sample Accurate Clock' method is more reliable and solid than having a
DAW send MIDI Clock. The reasons for that are beyond the scope of this
manual, but simply stated: DAWs are resource intensive applica ons running
on a mul -tasking computer that cannot place a high enough priority on
sending MIDI Clock, especially once the project grows to a certain size.
With the 'Sample Accurate Clock' method, the DAW sends audio for clock
instead, and due to the virtue of a DAWs ability to priori ze playing tracks of
audio at a given digital sample rate, the audio pulses for the clock are
guaranteed to be in sync with the rest of the tracks.

Se ng up the DAW to send Audio Clock
There are two ways to go.
1. The first is to load an audio file containing only 1 short square wave pulse,
and Paste it into the beginning of a new audio track in the DAW. (A suitable
audio file is downloadable from the Support sec on at jmkmusicpedals.com.)
Then use the DAWs "snap to grid" feature set for 64th Note Triplets and Paste a
copy of that audio file 23 more mes, making up 1 Quarter Note of length.
From there, depending on the DAW, you could loop this segment of audio, or
use "Select All", "Copy" and "Paste" repeatedly to grow the length of the track
exponen ally to make 1 long track of pulses.
2. The second and easier method is to install an instrument plugin, such as a
VSTi, that will use the DAWs Tempo to send out a 24 PPQN audio signal. At this
me, JMK Music Pedals has not created a branded plugin, but we have tested
CLOCKstep:MULTI using plugins that are available. See our Support sec on for
a list of any plugins that have been tested.
With either of these 2 choices, you must have a dedicated audio output from
your computer to send the clock signal.
Other control features of CS:M, such as Time Signatures and Transport Control,
exist at a higher level than clock data for maximum flexibility and control.
Combining Audio Clock and MIDI Control makes a very powerful system for
synchronizing with a DAW.
If CLOCKstep:MULTI does not respond to the audio, use the Audio IN Threshold
func on found in the Global Se ngs to calibrate CLOCKstep:MULTI to the
audio input.
