Hey all, thought others might find this useful. This is a plug and go custom unit that produces an audible metronome given a clock signal. By default it is listening for a clock on G4, but you can easily change this to any input, or the output of a global chain.
Parameters:
vol: a volume control clock: choose your clock input pitch1: the pitch of the click you hear on beats 2,3, and 4. By default, the lower pitch pitch2: the pitch of the click you hear on beat 1. By default the higher pitch tap: You can change your PPQN setting by adjusting the DIV parameter in the tap tempo unit inside the tap control
By default, this is set up for 24 PPQN (pulses per quarter note, which is a MIDI standard and fairly common in Eurorack).
If you clock is pulsing on:
Quarter notes, set to 1
Eighth notes, set to 2
Sixteenth notes, set to 4
etc.
Hereās a a quick video demo and quick setup instructions.
I was struggling with my own metronome unit and found this old thread that didnāt get enough love! So, I wanted to compare the units to see if we could do some cherry picking and produce a ācommunity metronomeā. I couldnāt get yours working though @Joe! It was somehow glitchy and weird Not sure what seemed to be the problem. Are you still using it with the current firmware?
I wanted to share my unit as a work in progress and I have some questions regarding the clock units in the ER-301 for anyone who can answer. There is no information yet on the wiki about these units and I canāt figure out some of the controls. So this is my metronome unit:
div: this is supposed to be a master divider so you can use a very fast clock and still hear a human scale 4/4 beat for example
Bpm: this is the tempo control in absence of a clock input
rate: forgot what this does, but it needs to be there itās just custom unit routing I thinkā¦
sign: here you can make move the base count to different signatures like 3/4 or 5/4
input: connect to external clock if you have one
Iām using two little samples instead of producing the sound in the unit like Joe did.
My metronome does work in a constrained environment but itās not rock solid. For starters I canāt get the master clock division to work. because the clock just stops if I increase the div control inside the BPM clock unit. @odevices any ideas on why that happens? Then, if I feed a very fast or slow clock to the metronome unit, all goes haywire, maybe for the same āsyncā reason.
The constant beat is just following every pulse which is easy to set up. Itās the base count that is causing me trouble because it requires dividing the clock. Right now I am using a tap tempo unit to divide the main clock because itās the only technique that gave me acceptable results, but after that I need to sync it back again with the original clock, otherwise it starts to drift off. Seems like tap tempo is somehow āinterpretingā the clock speed in it its own way and canāt exactly follow every beat to produce a super steady clock.
A general question about the Sync control in the Bpm unit: how does it work exactly, and am I using it in an acceptable way? I somehow assumed I could use this to override the manual Bpm in this unit (which would suit my use case), but that doesnāt seem to always be the case. If I move in extreme Bpm values manually up or down, it alters the external clock that is āsyncingā the unit.
Maybe I am going about this all the wrong way, but Iām keen to learn how these units work. Iāll probably start over when I do
Looks like I built this back in the 0.2 firmware. I havenāt used it in ages. Wouldnāt surprise me at all if something doesnāt work given that weāre coming up on 0.4!
Still seems like this might be pretty useful though. Like for example on the drumma! patch that @hyena built, to give you a sense of time before you start recording. Iāll check yours out when I get a little time (have a few things in the pipeline).
Thatās exactly what Iām using it for actually! I was simultaneously making a very similar drum unit as @hyenaās but mine is sample based. He beat me to it though, but I still want to build my own unit and I need this metronome for it. The idea is to use it as a guide for drumming, and then quantize the beat to that same clock.
Oh there is no great wizardry going on and no actual sound producing in the unit. Itās will be more of a sample beat maker, but I hope to make it into a rhythm workhorse for my compositions. When itās done and I think itās relevant I will definitely share it. There are still a couple of ingredients that Iām missing though.
