So on the manual :CLOCK input
The signal patched into the CLOCK input controls the timing of all four tracks simultaneously. While the ER-101 is not paused, a rising edge on the CLOCK input will advance the play cursor on all tracks. The threshold voltage for a valid trigger is 2.5V. This clock may be multiplied and/or divided, internally.
If i understand correctly this means the “clock”does not have to be a steady pulse but can be example a rhythmic pulse. Meaning each programed note will trigger everytime a rising edge of a gate is sent to the clk input?
That is correct. ER-101 does not require “regular” / steady clocks.
Every rising edge on CLOCK input will advance the playhead through the steps according to their step lengths.
Making the signal you use for your “clock” very versatile. Really is a cool sequencer.
thanks guys! btw is using loop points the best way to lock to a certain step when editing ?
if the “clk in” pulse is not a constant, I guess the multiply and division won’t work as expected, reason being the calculation is based on an evenly divided group of pulses ?
There is an excellent section explaining the behavior in the manual. It is of course impossible to smoothly multiply an unsteady clock without being able to accurately predict the future. The multiplied clock will stay in phase with the incoming clock, but its tempo will lag behind one full period of the incoming clock.
Also while the sequencer is paused, if you put it in follow mode you can navigate the sequence and the CVs outs will follow the current step. Theres no gate outs so you need to open up any VCAs. Not the same effect as looping a step but still allows you to slowly work through a sequence making changes.
